Preface
This manual describes how to use VAX. 4000 Model 300 timesharing and
VAXserver 4000 Model 300 server systems. The hardware and software
for each of these systems differs slightly, according to the function of the
system. The VAX. 4000 is a multiuser system that uses the VMS operating
system. The VAXserver 4000 system is a single-user system that uses VMS
or VAXELN operating systems. Both systems can function as an end- or
full-function node on an Ethernet network.
The manual is structured as follows:
•

Chapter 1 provides an overview of the systems.

•

Chapter 2 describes how to use each system.

•

Chapter 3 describes how to use options installed in the systems.

•

Appendix A lists related documentation.

•

Appendix B describes how to set and examine internal parameters for
RF-series ISAs.

•

Appendix C describes procedures for creating backup files.

•

Appendix D describes how to use VMSTAILOR to remove unwanted
VMS files from the system disk.

•

A glossary explains key tenns.

NOTE: VAXserver systems are designed to offer maximum performance for
applications that do not require timesharing. Some of the devices referred to
in this manual are designed for multiuser systems and may not be suitable
for server systems. Contact your Digital service representative if you have
any questions about whether use of a specific device is appropriate for your
server system.

1.1.1.1 Mass Storage Shelf
The mass storage shelf extends across the top of the enclosure. The shelf
contains a system control panel (SCP), tape drive, and up to three RF-series
ISAs (tapeless systems can have up to four RF-series ISAs). Each ISA has
its own panel with controls and indicators. Instructions for using ISAs and
the TK70 or TLZ04 tape drive are in Chapter 3. The SCP is to the right of
the storage devices. Figure 1-6 shows the mass storage shelf.

MLO"()04036

The SCP has two indicators: the Over Temperature Warning light and
the DC OK light. The red Over Temperature Warning indicator flashes to
indicate that the system's internal temperature is approaching a level that
may cause system components to overheat. In addition to the flashing Over
Temperature Warning light, an audible alarm also provides warning of a
possible over temperature condition. If the components continue to heat,
the system will automatically shut down to prevent components from being
damaged. Chapter 2 provides instruction for turning on the system after a
preventive shutdown due to overheat conditions.
The green DC OK light indicates that the power supply voltages are within
the correct operating range. If the DC OK light is not lit when the system
power is on, refer to the VAX 4000 Troubleshooting and Diagnostics manual
included in the Customer Hardware Information Kit.
Below the indicators are the Halt and Restart buttons. The Halt button is
a two-position button. When you press the button, the system halts. A red
indicator on the Halt button lights when the button is set to the in position.
Before you can enter console commands, press the Halt button again to

1-8 VAX 4000 Model 300 Operation

return it to the out position. When the Halt button is returned to the out
position, the console mode prompt »> is displayed on the console terminal
screen. Now you can enter console commands. If you inadvertently press
the Halt button, type "c IReturn I" to continue. Chapter 2 describes halting the
system in more detail.
CAUTION: Pressing the Halt button halts the system regardless of the
setting of the Break Enable / Disable switch on the console module.

Below the Halt button is the Restart button. The Restart button has a
green indicator. When you press the Restart button, the system returns to
a power-on condition and self-tests are run. If you have specified a device
as the boot device and if the BreaklEnable Disable switch is set to disable,
the system will reboot system software. Further instructions on restarting
your system are in Chapter 2.
NOTE: The Halt and Restart buttons can be disabled to prevent accidental
activation. Contact your Digital service representative if you want to disable
the controls on the SCP.

1.1.1.2 Card Cage
The modules in your system are mounted in a 12-slot card cage under the
mass storage shelf, as shown in Figure 1-7.

System Overview

1-9

Figure 1-7: Card Cage

Slots 12 - 6

Slots 5 - 1

__-----A------~~----~A~--__\

•
MLO·004037

The first four slots are reserved for memory modules. The fifth slot is
reserved for the central processing unit (CPU). A console module with
system controls and connectors covers these first five slots. Slots 6 through
12 are available for Q-bus option modules.
The number and type of modules installed in your system depend on your
configuration. Each Q-bus slot, even an empty one, is protected by a module
cover. Together the covers form a shield with a three-fold purpose:
•

To protect external devices from electrical interference generated by the
system

•

To protect the system from electrical interference generated by external
devices

•

To maintain air flow integrity

CAUTION: Do not operate the system without Digital-supplied module
covers. The covers are required to protect the equipment and to meet
international regulatory standards. Do not substitute other module covers
as they may not meet the required specifications.

1-10 VAX 4000 Model 300 Operation

Operating the system without the module covers has the following
consequences:
•

The system may overheat due to improper air circulation.

•

The system will not comply with FCC and VDE requirements for
electrostatic shielding and may produce electrical interference that
affects other equipment.

•

The system is susceptible to electrical interference or damage from
external sources.

The design of the module covers varies, depending on the type of module
installed in the slot. Modules requiring external cable connections, such as
communications controllers, have recessed covers that are riveted directly
to the module. The recessed module covers allow space for connecting
cables. Modules requiring no external cable connections, such as mass
storage controllers, are covered by flush covers. Empty slots are also
covered by flush covers which may be single or double width. All covers,
except those covering empty slots, have a label identifying the module
installed in the slot.
Cables connecting your system to peripheral devices (such as terminals,
modems, and printers) are attached to communications controllers. Each
cable can contain multiple lines. The cables run under the BA440 enclosure
and out the back or side of the enclosure, where the cables are split into
individual lines. Chapter 3 describes these connections in more detail.
1.1.1.3 Console Module
Your system can have up to four memory modules. The memory modules
occupy the first four slots of the card cage and are followed by the CPU.
The memory and CPU modules are behind the console module that covers
the first five slots. The console module, shown in Figure 1-8, has several
system controls and connectors.

The console module has the following components:

•

Power-On Mode switch - This three-position rotary switch
determines how the system responds at power-on:
Language Inquiry Mode (in the top position, indicated
by a profile of a face) causes the system to display a
language selection menu at power-on if your console
terminal supports multiple languages. Also, if a default
boot device has not been selected, this mode causes the
system to issue a list of bootable devices and prompts you
to select a device from the list. Once a device is selected,
the sY$tem autoboots from that device each time you turn
it on.

1-12 VAX 4000 Model 300 Operation

-t>

Run Mode (in the middle position, indicated by an arrow)
is the nonnal operating setting.

Loop Back Test Mode (in the bottom position, indicated by
a T in a circle) causes the system to run loopback tests on
the console serial line at power-on. This setting requires
specialloopback connectors and is for Digital Customer
Services use only.

•

Baud Rate Select switch - The Baud Rate Select switch is
used to set the system's baud rate to match that of the console
terminal. The factory setting is position 5 (9600).
Modified modular jack (MMJ) - This console terminal connector
provides the connection for the console tenninal.

The light-emitting diode (LED) display shows the testing
sequence during power-on.

Break EnablelDisable switch - When the switch is down
(position 0), breaks are disabled. When the switch is up (position
1), breaks are enabled. When breaks are enabled, pressing
IBreak I on the console terminal halts the processor and transfers
control to the console program. Using the console command SET
CONTROLP, you can specify the control character, ICtrllP I, rather than
IBreak I to initiate a break signal.
The Break EnablelDisable switch also controls what happens at
power-on. When breaks are disabled (down, position 0), the
system attempts to automatically boot software at power-on.
When breaks are enabled (up, position 1), the system enters
console mode (indicated by the »>prompt) at power-on.
Using the console command, SET HALT REBOOT or SET HALT
RESTART_REBOOT, you can set your system to automatically boot
software after the system is halted due to pressing IBreak I.

•

Bus node ID plugs - VAX 4000 systems have two separate
Digital Storage System Interconnect (DSSI) busses. 1\vo DSSI
bus node ID plugs, one for the internal DSSI bus, Bus 0, and
one for the external bus, Bus 1, identify the bus node of the
System Overview

1-13

CPU. These plugs are configured at the factory. For single-host
systems, Bus 0 is identified as bus node 6, bus 1 is identified as
bus node 7; for dual-host systems, both busses on the first host
are identified as bus node 7, and both busses on the second host
are identified as bus node 6.

•

DSSI connectors (DSSI Bus 1) - Two Digital Storage System
Interconnect (DSSI) connectors, labeled X and Y, on the console
module allow you to expand your system by connecting additional
mass storage devices to the second DSSI bus. '
Ethernet connectors - The console module has two Ethernet
connectors: a BNe-type connector for ThinWire Ethernet, and
a 15-pin connector for a standard Ethernet transceiver cable.
The Ethernet connector switch allows you to set the type of
connection. To use the standard transceiver cable connection,
set the switch to the up position. To use the ThinWire cable
connection, set the switch to the down position. A green indicator
light (LED) for each connector indicates which connection is
active.

1.1.1.4 DSSI Connector (DSSI Bus 0)

To the left of the card cage is the nSSI connector for DSSI Bus O. Bus

o provides the nSSI bus for ISAs installed in the system enclosure. The

connector allows you to expand your system by connecting additional mass
storage devices to the bus. You can also share mass storage devices with a
second system by forming a dual-host configuration. Figure 1-9 shows the
location of the nSSI connector for nSSI Bus O.

1.1.1.5 Power Supply Controls and Indicators
To the right of the card cage is the power supply. The power supply provides
power to the mass storage devices, the modules installed in the card cage,
and the fans.

To prevent damage due to overheating, the power supply monitors the
internal temperature and the speed of the fans. If the power supply detects
overheating or a fan failure, the power supply will shut down the system.
Figure 1-10 shows the controls and indicators on the power supply.

The controls and indicator lights function as follows:
Power switch - The power switch is used to tum system power
on and off. The off position is indicated by a 0; the on position is
indicated by a 1.
The power switch also functions as the system circuit breaker.
In the event of a power surge, the breaker will trip, causing the
power switch to return to the off position (0). Turning the system
on resets the circuit breaker. If the circuit breaker trips, wait one
minute before turning on the system back on.

•

AC Present Indicator - The orange AC Present indicator lights
when the power switch is set to on and voltage is present at the
input of the power supply. If the AC Present indicator does not

light when the power switch is set to on, refer to your VAX 4000
Troubleshooting and Diagnostics manual.
DC OK - When the green DC OK indicator is lit, the power
supply voltages are within the correct operating range. If the
DC OK indicator does not light when the power switch is set
to on, refer to your VAX 4000 7roubleshooting and Diagnostics
manual.

Fan Failure indicator - The amber Fan Failure indicator lights
if either of the two cooling fans stop working. The power supply
will automatically shut down the system as a precautionary
measure when a fan failure is detected. Call your Digital service
representative if a fan failure occurs.

Over Temperature Condition indicator - The amber Over
Temperature Condition indicator lights if the enclosure has shut
down due to an over temperature condition. Section 2.9 provides
instructions on recovering from an over temperature condition.

•

Power bus connectors - Three power bus connectors allow you
to configure a power bus for systems expanded with the R400X
or B400X expander. The power bus allows you to turn power
on and off for one or more expanders through the power supply
designated as the main power supply: this way, one power switch
can control power for an entire expanded system. Figure 1-11
illustrates a possible power bus configuration for an expanded
system.

NOTE: Dual-host systems should not be configured with a power
bus. Inadvertently shutting off a host system defeats the added
reliability of a dual-host system.
The main out (MO) connector sends the power control
MO bus
signal to the expander. One end of a power bus
cable is connected here, the other end is connected to the
secondary in (81) connector of an expander power supply.

The secondary in (81) connector receives the power bus
control signal from the main power supply. In a power
bus with more than one expander, the power control bus
signal is passed along, using the secondary in and out
connectors as shown in Figure 1-11.

System Overview

1-17

The secondary out (SO) connector sends the signal down
the power bus for configurations of more than one
expander.

1.1.1.6 Fans
1\vo fans located under the card cage draw air in through the top of the
enclosure, down through the card cage, and out the bottom. The speed of
the fans varies, depending on the surrounding room temperature. To reduce
the load on the fans, keep the system away from heat sources. Figure 1-12
shows the air flow through the system enclosure.
NOTE: The power supply monitors the fans. If either fan stops working,
the Fan Failure indicator on the power supply lights, and the system
automatically shuts down as a precautionary measure. Call your Digital
service representative if a fan fails.
NOTE: The fan speed control can be set so that the fans will run at their

maximum speed. This setting is recommended ifyou want potentially higher
system module reliability~ and do not object to the increased fan noise.
Contact your Digital service representative to override the fan speed control.

1.2 Functional Description of Base System
Each VAX 4000 system includes base system components common to all
systems. Your system may have optional components as well. Your system
was configured at the factory, based on your order.
The following sections describe base system components and options, in

turn.

1.2.1 Base System Components
Base system components include the following:
•

Central processing unit (CPU)

•

Console serial line unit (SL U)

•

Main memory

•

Network controller

•

Embedded DSSI host adapters

System Overview

1-19

1.2.1.1 Centra~ Processing Unit (CPU)

The central processing unit (CPU) controls the execution of all instructions
and processes. The CPU circuits contain the logic, arithmetic, and control
functions used by the system.
1.2.1.2 Console Serial Line Unit (SLU)

Each system has a serial line unit connecting the console terminal to the
system. The SLU connector (a modified modular jack) is located on the
console module. The console serial line provides a means of communicating
with the CPU.
1.2.1.3 Main Memory

Main memory provides the electrical storage area for data and instructions
used by the CPU. When you start your system, the operating system is
loaded into main memory. Application programs must also be loaded into
memory.
When the system cannot load everything into memory at once, it reads
in units of data called pages (512 bytes of data) from disk. A large main
memory increases the efficiency of processing, since fewer pages must be
copied to and from the disk. Each configuration comes with a standard
memory option. There is room for up to four memory modules. By adding
more main memory, you can increase efficiency.
The contents of memory are volatile. This means they are lost when
you turn off power to the system. Use mass storage devices, such as
integrated storage assemblies and tape cartridges, to store software and
data permanently.
1.2.1.4 Network Controller

Network communications controllers allow you to connect to an Ethemet
network. With a network connection and appropriate DECnet software, you
can use network services, such as mail; access data stored on other systems;
perform operations, such as editing and printing on remote systems; and
share resources, such as laser printers. Your system comes with an onboard
Ethemet controller that is part of the CPU. The system can connect to
an Ethernet network through either standard Ethemet cable or ThinWire
Ethemet cable. Connectors for both types of cables are on the console
module.
.

1-20 VAX 4000 Model 300 Operation

1.2.1.5 Embedded DSSI Host Adapters
Your system has two Digital Storage System Interconnect (DSSI) adapters
built into the CPU. The DSSI adapters provide two separate DSSI busses
(Bus 0 and Bus 1) through which the CPU can communicate with the RFseries ISAs. Each nSSI bus can support seven RF-series ISAs.

The DSSI host adapters also allow you to link one of the DSSI busses
to a second host to form a dual-host configuration. When a nSSI bus is
extended to a second system, both systems can share up to six ISAs. Refer
to Section 1.3 for further discussion of dual-host systems.

1.2.2 Optional Components
System options can include multiples of components that are part of the
base system (for example, additional memory modules or ISAs) and the
following kinds of options:
•

Mass storage devices and controllers

•

Mass storage subsystems

•

Mass storage expanders

•

Communications controllers and adapters

•

Real-time controllers

•

Printer interfaces

1.2.2.1 Mass Storage Devices and Controllers
Mass storage devices record data on magnetic media. The data recorded is
not lost when you turn off the system, but can be altered or erased if you
record over the data. Use mass storage devices to store data and software
permanently. When the data or software is needed, the CPU transfers it
from the mass storage device into main memory. The two primary types
of mass storage devices are the RF-series ISAs and devices with removable
!D.edia, such as tape cartridges and compact disks.
Integrated Storage Assemblies
Up to four RF-series ISAs can be installed in your system. An ISA is
an intelligent storage device that contains its own controller and server.
Special mounting bracketry allows the device to plug directly into the
BA400-series backplane.
Devices with Removable Media
Devices with removable media, such as tape cartridges, are used as both
input and output devices. In addition, compact optical disks are used as

System Overview

1-21

input devices when you install software or copy data to your system. You
use tape cartridges and tapes as output devices when you copy software or
data from your system. You can copy individual files or programs, or you
can copy (back up) the contents of an entire fixed disk. Tapes are commonly
used to archive data.
Mass Storage Controllers and Adapters

All mass storage devices require a controller, a device that controls activity
between the CPU and the mass storage devices. While the controller
for each RF-series ISA is built into the storage assembly, other storage
options require a controller module located in your system's card cage. The
controller for the TK70 tape drive is the TQK70j the KDA50 is a controller
for RA-series disk drives. Each KDA50 controller supports up to four RAseries disk drives.
The KZQSA adapter allows the CPU to communicate with the TLZ04 tape
drive or RRD40 digital compact disk drive through a Small Computer
System Interface (SCSI). Each KZQSA adapter can support up to three
drives.
The CPU communicates with the ISAs through a Digital Storage System
Interconnect (DSSI) adapter, which is built into the CPU. Your VAX 4000
system has two DSSI adapters, and hence, two separate DSSI busses. Each
DSSI bus is capable of supporting seven integrated storage assemblies. A
third and fourth DSSI bus can be added to your system by using up to two
KFQSA DSSI storage adapter modules. Each KFQSA storage adapter can
support up to seven RF-series ISAs.
1.2.2.2 Mass Storage Subsystem.

Several optional mass storage subsystems are available for VAX 4000
systems. Such subsystems include RRD40 Digital Disk Subsystems, the
RV20 Optical Disk Subsystem, TS05 and TUB1 tape drives, and the SA600
Storage Array (with up to eight RA90 disk drives). If your system includes
an optional mass storage subsystem, refer to the user's guide or owner's
manual for that subsystem for instructions on how to operate the device.
1.2.2.3 Mal. Storage Expander.

You can expand the mass storage and Q-bus capacity of your VAX 4000
system by using expanders. The R400X mass storage expander provides
space for up to seven additional RF-series ISAs. Using R400X expanders,
you can fill both DSSI busses for a total of 14 ISAs.
The B400X expander provides 11 additional Q-bus slots and space for up
to four additional RF-series ISAs. Refer to the addendum shipped with the
expander for more information.

1-22 VAX 4000 Model 300 Operation

1.2.2.4 Communications Controllers
Besides the console serial line, most systems have additional communications controllers for connecting additional terminals, and for communicating with other systems over telephone or network lines. Communications
controllers provide standard interfaces between peripheral devices and the
system. Many communications controllers provide support for multiple
data lines.
The following types of communications controllers are available:
•

Asynchronous serial controllers

•

Synchronous serial controllers

•

DECservers

•

Network controllers

Serial controllers transmit data one character at a time. A device at the
transmitting end breaks bytes of data into bits. A device at the receiving
end assembles incoming bits into bytes of data.

Asynchronous Serial Controllers
Asynchronous serial controllers provide low-speed connections between
peripheral devices and the system. Asynchronous communication between
the system and the peripheral depends' on recognition of a pattern of start
and stop bits, not on a time interval.
Asynchronous serial controllers may be divided into those without modem
support and those with modem support.
You use serial controllers without modem support to connect additional
terminals and printers to your system. For example, the CXA16 module
provides connections for up to 16 serial lines with no modem support.
NOTE: Printers equipped with a microprocessor (intelligent printers) may
require modem control signals to function correctly. Do not attach a printer
requiring modem control signals to a controller with no modem support.
Check your printer documentation to determine the proper communications
interface for your printer.

Communications controllers with modem support allow you to communicate
over telephone lines. With a modem connected to your system, you can
access other computers and you can dial into your system from a remote
terminal or computer.
Computers transmit digital signals, while telephone lin~s (with the
exception of digital leased lines) transmit analog signals. When two

System Overview

1-23

computers communicate over telephone lines, a modem is required at both
the transmitting and receiving ends of the line. At the transmitting end, the
modem converts digital signals from the computer (or terminal) to analog
signals prior to transmission. At the receiving end, another modem converts
the analog signals back into digital signals the computer can process.
The degree of modem support depends on the number of modem control
signals recognized by the device. Full modem support (according to Digital
standards) requires recognition of eleven signals. The CXYOB module
supports up to eight serial lines with full modem support.
Synchronous Serial Controllers

Synchronous serial controllers provide high-speed connections between
systems. Communication between synchronous devices depends on time
intervals that are synchronized before transmission of data begins.
Synchronous devices can also have modem support.
DECservers

DECservers are terminal servers (a combination of hardware and software)
that allow you to connect multiple terminals or printers to hosts in an
Ethernet Local Area Network (LAN).
Terminal servers perform the functions of traditional data terminal
switches but multiplex the lines over the Ethernet. Using a DECserver
offloads communications processing from the host system.
Network Controllers

Network communications controllers allow you to connect to an Ethernet
LAN or other network type. With a network connection and appropriate
DECnet software, you can use network services, such as mail; access data
stored on other systems; perform operations, such as editing and printing on
remote systems; and share resources, such as laser printers. The network
controller function for your system is implemented on the CPU module, but
a second network controller, the DESQA Ethernet, adapter module can be
added to your system.
1.2.2.5 Re.I-Tlme Controllers

Real-time controllers interface with devices that monitor or control
particular processes, lor example, laboratory equipment or manufacturing
equipment connected to the system. Typically, real-time controllers are
parallel devices, not serial devices.

1-24 VAX 4000 Model 300 Operation

1.2.2.6 Printer Interfaces
Some printers require specific interfaces to communicate with the system.
For example, the LGOl, LG02, and LP25-LP29 printers require the LPVllSA interface module.
1.2.2.7 Other Available Options
Your system arrives configured with the options you ordered. As your needs
change, you can add more options. Your Digital sales representative can
advise you on available options. VAX 4000 Model 300 Thchnical Information
describes the options currently available for VAX 4000 systems. Digital
provides installation for additional options that you order.

1.3 Dual-Host Capability (VMS Systems Only)
A dual-host system consists of two systems in a VAXcluster sharing their
ISAs via a Digital Storage System Interconnect (DSS!) bus. Each system
can have direct access to any of the ISAs in either system; this can include
a shared common system disk.
The primary application for such a configuration is a VAXcluster system.
The simplest dual-host configuration, for example, is to configure one
system disk to be used as the system disk by both systems. The system
disk physically resides in one enclosure, however, both systems have equal
access to the system disk and to any other DSSI mass storage device in
either enclosure.
A DSSI ISA, such as the RF71, has a built-in dual-host capability that
allows it to connect to two DSSI host adapters. The DSSI storage adapter,
embedded in the system's CPU, allows you to extend a DSSI bus by
physically connecting it to a second system.
Using an external DSSI cable, any two DSSI-based systems can be
connected to form a dual-host configuration. Figure 1-13 shows a dualhost configuration with two VAX 4000 systems.
NOTE: Dual-host capability for VAX 4000 systems is only supported under
VMS (version 5.3-2 and later) when the two systems are configured into the
same VAXclus ter.

The benefits of a dual-host configuration are:
•

VAXcluster features such as shared data across systems and satellite
nodes.

•

Higher system availability - If one of the DSSI-based systems is
unavailable, for example, due to a system malfunction, the satellites

System Overview

1-25

booted through it are able to continue operating through the other
system.
. If one of the nSSI-based systems fails, all satellite nodes booted through
that system lose connections to the system disk. Each satellite node knows,
however, that the system disk is also available through a second path. The
satellite nodes establish a new connection through the other system and
continue operation.
To increase system availability, a second system disk may be added to each
boot node. In the event of one system disk failure, the remaining system
disk would continue to serve one nSSI-based system and the satellite nodes
booted through it. As with any VAXcluster, however, a second system disk
improves availability while increasing system management tasks.

Chapter 2

Operating the System
This chapter describes how to operate your VAX 4000 system once
the system software has been installed or you have completed startup
procedures for factory-installed VMS.

2.1 Before You Operate the System
This chapter assumes that your system has been properly installed.
Installation includes running the diagnostic software shipped with your
system and installing the base operating system, or completing the first
time startup procedures for factory-installed VMS. Refer to Appendix A of
the VAX 4000 Model 300 Installation manual for instructions on starting up
factory-installed VMS. To install other operating system options or layered
products, see the instructions in your system software installation manual
or layered product installation manual. Some of the instructions may
require you to open the front door of the system to change switch settings
on the console module.
The remainder of this chapter assumes that system software has been
installed and first time startup procedures for factory-installed VMS have
been completed.

2.2 Switch Settings
Switch settings vary, depending on the operation being performed. The next
two sections describe switch settings for normal and for special operations.
Set the switches according to your needs.

2.2.1 Normal Operation
Switch settings for nonnal operation are the following:
•

The Break EnablelDisable switch on the console module is set to disable
(down, position 0). Digital recommends you run the system with breaks
disabled to prevent the user from inadvertently halting the system by
pressing IBreak I on the console terminal. Halting the system causes all
activity to stop.

Operating the System

2-1

With breaks disabled, the system automatically boots system software
when powered on.
NOTE: You can use the console command SET CONTROLP to specify
the control character, IClrvpl, rather than IBreakl, to initiate a break signal.

Using the console command, SET HALT REBOOT or SET HALT
RESTART_REBOOT, you can set your ~stem to automatically boot
software after the system is halted due to pressing IBreak I.
•

The Power-On Mode switch on the console module is set to Run
(indicated by an arrow).

•

The Baud Rate Select switch on the console module is set to 9600
(indicated by a switch setting of 5).

•

The Write-Protect button for each RF-series ISA is set to out (not lit).
This setting allows system software to write to the storage element.

•

The RunlReady button for each RF-series ISA is set to in (glows green
when the storage element is not being used). This setting makes the
storage element available for use.

•

The Halt button on the SCP is set to out (not lit).

•

For expanded systems using power bus cables to link the R400X or
B400X expander, the power switches on all expander power supplies
should remain on (set to 1) at all times. The system power supply
sends the power bus signal needed to turn the expanders on or off.

2.2.2 Special Operation
Certain operations require that you change some of the normal operating
settings.
•

If you need the ability to halt the system from the console terminal, for
example, when installing system software or performing certain types
of backup, set the Break EnablelDisable switch to enable (up, position
1). This allows you to halt the system by pressing IBreak! on the console
terminal.
NOTE: You can use the console command SET CONTROLP to specify
the control character, ICtrvpI, rather than IBreak I, to initiate a break si6nal.

Using the console command, SET HALT REBOOT or SET HALT
RESTART_REBOOT, you can set your system to automatically boot
software after the system is halted due to pressing IBreakl.

2-2 VAX 4000 Model 300 Operation

•

If you want data on a particular ISA to be write-protected, you must
set the Write-Protect switch to in (glows).
NOTE: ISAs containing system software and user accounts must remain
write-enabled. ISAs containing applications or sensitive data may be
write-protected.

•

If you want to use the Language Selection Menu to select a new
language for the console program, before you turn on your system, set
the Power-On Mode switch to Language Inquiry Mode. A human profile
indicates the language inquiry mode. When you tum on your system,
a Language Selection Menu appears, as shown in Figure 2-1.

NOTE: If you do not select a language within thirty seconds, the system
defaults to English (United States / Canada).

If the Power-On Mode switch is set to Run Mode (indicated by an arrow),
then the language selected is saved and is automatically used during
subsequent reboots of the system.

Operating the System

2-3

NOTE: If the Power-On Mode switch is set to Language Inquiry Mode
(indicated by the human profile), the system will prompt for the language
at each power-on.

In addition to the Language Selection Menu, the system may issue a
list of bootable devices and prompt you to select a device from the list.
If this happens, refer to Section 2.4.1 for more information.
If your system has been powered off for more than 10 days, the
battery unit that saves the system clock and the language selection may
have run down. The Language Selection Menu will be automatically
displayed when you power on your system, regardless of the Power-On
Mode switch setting. Once the system is booted, reset the system clock
as described in your system software manual.

2.3 Turning On the System
Once you have set the switches correctly, you are ready to tum on the
system. Use the following procedure:
1. Turn on the console terminal and wait for it to complete its self-tests.

2. Turn on the system by setting the power'switch to 1.
NOTE: For systems using the R400X or B400X expander linked by a
power bus cable, the power switch on the VAX 4000 provides the power
control bus signal to the expander(s). Setting the power switch to on (1)
on the VAX 4000 will cause the expander(s) to power on as well. The
power switch on the expander(s) should always remain in the on position
(1).

When you tum on the power, you should see the indications listed in Table
2-1.

chapter, the CPU is identified as a KA670-A, and the versions of the
firmware and primary bootstrap are indicated as n.n. Your system will
display actual version numbers. The console terminal then displays a
countdown as the system tests itself. When the self-tests are successful,
the system either autoboots system software or goes into console mode, as
described in Sections 2.4.1 and 2.4.2.
If your system detects an error during its self-tests, it displays an error
summary consisting of several lines of hexadecimal numbers. A Digital
service representative can use the error summary to diagnose the system.
Depending on the type of error, one or more error summaries may display
on the console terminal. A sample error summary is shown in Figure 2-2.

2.4 Booting the System
VAX 4000 systems boot in one of two ways. You can configure the system
to autoboot on power-on or you can manually boot the system from console
mode. The Break EnablelDisable switch setting determines how the system
boots.

2.4.1 Autobaoting the System
When the Break EnablelDisable switch is set to disable (the normal
operating setting), the system runs self-tests and, on completion, attempts
to load system software. Additionally, if the Break EnablelDisable switch
is set to enable, and the halt action REBOOT or RESTART REBOOT has been
defined using the SET HALT command, the system will automatically attempt
to load system software.
Depending on whether or not a boot device has been selected, the system
loads system software or prompts you to select a boot device.
Loading System Software (With Boot Device Selected)
When a boot device has been selected, the system identifies the boot device
and the number "2" displays on the screen. As the system begins booting,
the countdown continues from 1 to O.

Changing the Boot Device
Once a boot device is identified, the system autoboots from that device each
time you turn it on, until you do one of the following:

•

Change the setting of the Break EnablelDisable switch to enable (up,
position 1). If you do so, the system will not autoboot but will enter
console mode after completing self-tests (assuming you have not defined
a halt action of REBOOT or RESTART_REBOOT using the SET HALT console
command). Refer to Section 2.4.2 for instructions on booting from
console mode.

•

Change the boot device by using the SET BOOT command.

2-8 VAX 4000 Model 300 Operation

Using the SET BOOT Command

To direct the system to boot automatically from a specific device or to change
the setting of the default boot device, put the system into console mode and
at the »> prompt, enter "SET BOOT device-name". For example,
»>SBT BOOT BZAO

sets the system default boot device to be the Ethernet controller.
Once you have selected a boot device, the system autoboots from that device
each time you turn it on.
Using "SET BOOT device-name,device-name,device-name", you can also
specify a string of default boot devices (up to 32 characters, with devices
separated by commas and no spaces) for which the system will check for
bootable software. The system checks the devices in the order specified and
boots from the first one that contains bootable software. For example,
»>SBT BOOT DtJAO,DIAO,MtJAO,BZAO

directs the system to use DUAO, DIAO, MUAO, and EZAO as the default
boot devices. When the system autoboots, or if the BOOT command is used
without specifying a device, the system will boot from the first default boot
device that contains bootable software.
NOTE: If included in a string of boot devices, the Ethernet device, EZAO,
should only be placed as the last device of the string. The system will
continuously attempt to boot from EZAO.

To determine the name of the device from which to boot the system, refer
to Table 2-2, or enter the SHOW DEVICE command at the console prompt
»>. Figure 2-6 shows a sample list of devices. The system displays the
logical device name, preceded by a dash (-), for each device.
NOTE: Selecting a default boot device other than the Ethernet device, EZAO,
is not appropriate for diskless and tapeless systems which must boot software
over the network.

Loading System Software
To load system software from console mode, enter the BOOT command,
"BOOT device name". For example,
»>8001' NOAO

tells the system to boot software from a cartridge in the TK70 tape drive.
If you enter the BOOT command without specifying a device, the system
will attempt to boot from the default boot device, or string of devices defined
by the SET BOOT command.
Using "BOOT device-name,device-name1device-name", you can also specify
a string of boot devices (up to 32 characters, with devices separated by
commas and no spaces) for which the system will attempt to boot software.
The system checks the devices in the order specified and boots from the
first one that contains bootable software. For example,
»>8001' DOAO, DIAO, NOAO, EZAO

directs the system to boot from the first device in the list that contains
bootable software.
NOTE: If included in a string of boot devices the Ethernet device, EZA01
should only be placed as the last device of the string. The system will
continuously attempt to boot from EZAO.

Operating the System

2-11

NOTE: 7b determine the name ofthe device from which to boot the system,
refer to 7hble 2-2.

Software manuals may instruct you to power on with break enabled and to
use the BOOT command.

2.5 Using the System
Once the system software is loaded, the first display for the system software
appears on the console terminal after a few seconds. That display is
described in the system software documentation.
You are now ready to use the system. Refer to the system software manuals
and application manuals for more specific instructions on using the system.
Your system software manuals cover the following:
•

Installing software on your system

•

Running software to perform tasks

•

Making and restoring backup copies of system software or data files

•

Accessing devices and utilities in your system

2.6 Halting the System
Halting the system interrupts all processes and returns control to the
console program. You may need to halt the system during software
installation. Or, you may want to boot the system from another device, for
example, a tape cartridge containing MicroVAX Diagnostic Monitor (MDM)
software.
CAUTION: Halting your system without following the shutdown procedure

described in your system software manuals may result in loss of data.
You can halt the system in two ways:
•

You can press the Halt button twice - in to halt the system, and out
to enter console mode.

•

If the Break EnablelDisable switch on the console module is set to
enable (indicated by 1) you can press the IBreak I key on the console
terminal. If the Break EnablelDisable switch is not set to enable and
you wish to halt the system by.pressingIBreakl, change the setting of the
Break EnablelDisable switch from disable to enable.

2-12 VAX 4000 Model 300 Operation

NOTE: You can use the console command SET CONTROLP to specify
the control character, IctrllPl, rather than jBreakl, to initiate a break signal.
CAUTION: If you shut off your console terminal while breaks are enabled,
the system interprets the action as a break, and the system halts.

If you are using a system that is part of a VAXcluster, do not halt, restart,
or turn off the system without consulting the cluster manager. Performing
any of these activities will interrupt the processes of the entire cluster.
When the console mode prompt (»» is displayed on your screen, the
system is halted.
If you inadvertently halt the system, type "c IRetuml" at the console prompt.
The processes interrupted by the halt will continue.

2.7 Restarting the System
NOTE: Restarting the system aborts all current and pending operations. 7b
prevent loss of data, warn all users to log off prior to restarting the system.
Follow the shutdown procedure described in your system software manuals
before restarting the system.

Restarting returns the system to a povrer-on condition. All current and
pending operations are aborted and the usual power-on tests are run.
You restart the system by pressing the Restart button on the system control
panel.
NOTE: The Halt button must be out (not lit) to effect a restart operation.

2.8 Turning Off the System
CAUTION: Turning off your system without following the shutdown
procedure described in your system software manuals may result in loss
of data.

Once you have completed the recommended procedure, you can turn off
your system by setting the power switch to O.
NOTE: For systems expanded with the R400X or B400X expander and
linked by a power bus cable, you need only turn off the system unit: The
expander(s) will power off when you set the system power switch to off (0).
Note that the orange ac indicator on the expander power supply should
remain lit even though the system is powered off.

2.9 Recovering from an Over Temperature
Condition
If your system's internal temperature approaches a level that may cause
components to overheat, an audible alarm will sound and the Over
Temperature Warning indicator on the SCP will flash. If the temperature
continues to increase, the system will automatically shut down.
If the overheat warnings are activated, the alarm sounds and the Over
Temperature Warning indicator flashes.
When the system shuts down due to overheating, the Over Temperature
Condition indicator on the power supply remains lit. To recover from a
shutdown, set the power switch to off (0) and wait five minutes before
turning on the system.
To prevent an over temperature condition, use the following precautions:
•

Make sure your system is away from heat sources.

•

Check that the system's air vents are not blocked.

•

Check that the room temperature is within acceptable limits as specified
in your VAX 4000 Site Preparation manual.

Operating the System Options
This chapter describes how to use options that may already be part of your
system, or that you can add to your system. The following types of options
are covered:
•

Mass storage devices and controllers

•

Communications controllers

•

Real-time con trollers

•

Printers

NOTE: Some of these options may not be appropriate for VAXserver 4000
systems. Contact your Digital representative if you have any questions about
whether a specific option is appropriate for your system.

3.1 Mass Storage Options
The following mass storage options are included with VAX 4000 systems:
•

RF-series Integrated Storage Assembly (lSA)

•

TK70 or TLZ04 tape drive

NOTE: In addition, the RV20 Optical Disk Subsystem, RRD40 Digital Disk
Subsystems, and TSV05 and TUB1 tape drives can be attached to the VAX
4000 system. If your system contains one of these options, refer to the user's
guide or owner's manual for instructions on how to operate the device.

This chapter describes how to use the controls for the RF-series ISAs
and the TK70 and TLZ04 tape drives. In the case of the tape drives, it
also describes how to insert and remove the tape cartridge. To use any
mass storage device, you must properly identify the device to the operating
system and use appropriate operating system commands. Refer to your
system software documentation for details.

Operating the System Options

3-1

3.1.1 RF-Series Integrated Storage Assemblies
Your system may have up to four RF-series ISAs, or up to three RF-series
ISAs and a TK70 tape drive. When your system has multiple ISAs, Digital
recommends that you separate them according to function. For example, if
your system has two ISAs, you may want to use them as follows:
•

ISA 0 contains the operating system and applications installed on the
system.

•

ISA 1 contains work areas for each user with an account on the system.

The storage capacities and other specifications for RF-series ISAs are listed
in VAX 4000 Model 300 '1echnical Information.
Refer to Appendix B of this manual for information on setting or examining
internal parameters for RF-series ISAs.
RF-Serles Controls and Indicators
Each RF-series ISA has controls and indicators on its front panel. To access
the ISA controls you need only open the upper door (top key position).
Figure 3-1 shows the front panel of an RF-series ISA
NOTE: If your system has less than the maximum number of I8As: three if
you have a TK70 tape drive, or four without the tape drive, a blank [SA front
panel with no controls or indicators is used to cover the empty [SA cavities.
The front panels are required to meet international regulatory standards.

system can write to the ISA. Your system disk (the ISA containing system
software) and ISAs containing work areas for users should be write-enabled,
the normal operating setting.
If you want to write-protect an ISA containing sensitive data that you do
not want changed or accidentally erased, set the Write-Protect button to in
(lit).

Changing the Bus Node 10 Plugs
Spare bus node ID plugs are supplied with your system. Use the spare
plugs to renumber your ISAs if you reconfigure your system with an R400X
expander, or if you create a dual-host configuration.

3-4 VAX 4000 Model 300 Operation

The bus node ID plugs have prongs on the back that indicate the bus node
number (and by default, the unit number) of the ISA. To remove a bus node
ID plug, grasp it firmly and pull straight out. To insert a bus node ID plug,
align the two center prongs with the two center slots and press the plug
into the slots. See Figure 3-2.
Figure 3-2: Inserting Bus Node 10 Plugs

MLO-004045

Use the rules below for renumbering your storage assemblies:
•

For each DSSI bus, do not duplicate bus node numbers for your storage
assemblies. You can only have one storage assembly on bus 0 identified
as bus node 1, one storage assembly as 2, and so on; you can only have
one storage assembly on bus 1 identified as bus node 1, one storage
assembly as 2, and so on.

•

By convention, the ISAs are numbered in increasing order from right
to left.

NOTE: If you change the bus node ID plugs while the system is operating,
you must turn off the system and then turn it back on for the new plug
positions to take effect.

3.1.2 TK70 Tape Drive
The TK70 tape drive is located behind the upper door of the system. To use
the drive, move the key to the top position and open the door.
The TK70 tape drive holds one removable magnetic tape cartridge. The
drive can read data written on either a CompacTape II or CompacTape
cartridge. You can identify the type of cartridge by the label on the
cartridge.
You can use a CompacTape II or CompacTape cartridge as an input device
to load software or data into your system. The TK70 drive can read data
on both types of cartridges, written by either a TK70 drive or a TK50 drive.
(The TK50 drive records data in a format different from that of the TK70.)
You should use a CompacTape II as an output device to make copies or
backups of software or data. The TK70 drive cannot write to a CompacTape
II or CompacTape that has been previously written by a TK50 tape drive.
TK70 Tape Drive Controls

The tape drive has two primary controls: the cartridge insert/release handle
(subsequently referred to as "the handle") and the Unload button. You use
the handle to insert or remove cartridges and lock them into position. Pull
the handle open to insert or remove a tape cartridge. Push the handle
closed to lock a tape cartridge into position and load the tape.
You use the Unload button to rewind and unload the tape. Unloading and
rewinding can also be controlled by software. Refer to your system software
manuals for appropriate commands.
The drive also has three indicator lights that tell you the status of the drive.
•

Orange light (Write-Protected): A steady orange light indicates that the
cartridge is write-protected.

•

Yellow light (Tape in Use): A steady yellow light indicates that the tape
is loaded. A blinking yellow light indicates that the tape is in motion.

•

Green light (Operate Handle): A steady green light indicates that you
can move the handle to insert or remove a tape. A blinking green light
indicates a cartridge load fault. You can also move the handle when
the green light is blinking.

All three lights blinking simultaneously indicates a fault condition.
Figure 3-3 shows the TK70 tape drive with the controls and indicator lights
labeled.

3-6 VAX 4000 Model 300 Operation

To operate the drive properly, you must carefully monitor the indicator
lights. The instructions for inserting and removing cartridges, which

The TK70 tape drive operates like a reel-to-reel tape deck. Inside the drive
is a take-up reel with a leader attached. Inside the cartridge is a single
reel containing the magnetic tape. When you insert the cartridge and push
in the handle, the leader in the drive automatically couples with the leader
in the cartridge, and the tape winds onto the take-up reel. The coupling
and winding process is called loading. When the automatic loading process
is complete, the tape is ready to use.

Once the cartridge is loaded, you cannot remove it without rewinding and
uncoupling the leaders, a process called unloading. Even if you have not
used the tape, you must unload it before you can remove the cartridge.
When you press the Unload button, the tape rewinds into the cartridge
and the leaders uncouple.

3.1.2.2 labeling a Tape Cartridge
When recording data on a cartridge, label its contents.
For your
convenience, a slot for the label is provided on the front of the cartridge.
Write the identification on the label and insert the label in the slot on the
front of the cartridge, as shown in Figure 3-4. The label is visible when
the tape is in the drive.

3.1.2.3 Write-Protecting a Tape Cartridge
Write-protecting a tape cartridge prevents accidental erasure ofinfonnation
stored on the tape. You can write-protect a tape cartridge in two ways:

•

Set the write-protect switch on the cartridge to the write-protect
position.

•

Write-protect the cartridge by using operating system commands
described in your system software manuals.

Your system can read information on the tape regardless of the position of
the write-protect switch or whether writing is software-disabled. However,
the system cannot write data to the tape when the write-protect switch is
set to the write-protect position, or when writing is software disabled.
When you use a cartridge to install software, make sure the cartridge is
write-protected. Two icons on the switch indicate the write-protect status,
as shown in Figure 3--5. An orange rectangle is visible when the switch is
in the write-protect position. If you do not see an orange rectangle, slide
the switch toward the label slot.
When you insert a write-protected cartridge into the drive, the orange
indicator light comes on. The system recognizes the tape as being writeprotected under anyone of the following conditions:
•

The write-protect switch on the cartridge is set to the write-protect
position.

•

An operating system command has write-protected the tape.

•

A tape recorded on a TK50 tape drive is inserted into the drive.

Removing write-protection depends on how the tape was recorded and
how it is write-protected. You cannot write-enable a tape recorded on a
TK50 tape drive either by moving the write-protect switch on the cartridge
or by using software commands. The TK70 drive always recognizes a
tape recorded on a TKSO drive as write-protected. You can remove writeprotection on tapes recorded on a TK70 drive as follows:
•

If the cartridge is write-protected only by the write-protect switch on
the cartridge and not the operating system, moving the switch to the
write-enabled position causes the orange light to go out at the end of
the executing command.

Operating the System Options

3-9

Figure 3-5: Tape Cartridge Write-Protect Switch

•

If the cartridge is write-protected only by a software command and
not the write-protect switch, l"emoving the operating system restriction
causes the orange light to go out.

•

If the cartridge is write-protected by both the switch on the cartridge
and a software command, you must change the switch setting and
remove the operating system restriction.

3-10 VAX 4000 Model 300 Operation

When you use a CompacTape II cartridge to make a backup copy of files,
make sure the orange write-protect light on the TK70 drive is off. If the
light is not off, check for any of the write-protect conditions described above.
Change the switch setting and/or operating system restriction as necessary.
Do not begin your operation until the orange light goes off.
3.1.2.4 Tape Cartridge Handling and Storage Guidelines

•

Do not touch the exposed surface of the tape.

•

Do not drop the tape cartridge. The impact from a fall can damage the
tape cartridge.

•

Allow new tapes to stabilize at room temperature for 24 hours before
using them.

•

Place an identification label only in the label slot on the front of the
tape cartridge.

•

Store tape cartridges in a dust-free environment.

•

Keep tape cartridges away from direct sunlight, heaters, and other
sources of heat. Store tape cartridges in a stable temperature between
10° and 40°C (50° and 104°F).

•

Store tape cartridges where the relative humidity is between 20 and 80
percent.

•

Keep tape cartridges away from magnets and equipment that generate
magnetic fields, such as motors, transformers, terminals, and audio
equipment.

•

Keep tape cartridges away from x-ray equipment.

3.1.2.5 Inserting a Tape Cartridge

Before you use the tape drive, make sure the system is turned on (the
power switch glows). During power-on, the TK70 drive runs self-tests that
last a few seconds. All three lights (orange, yellow, and green) come on
momentarily, then the yellow light blinks during the self-tests. At the
end of the tests, the yellow light goes off and the green light comes on,
accompanied by a short beep. The green light and the beep indicate that
you can move the cartridge release handle.
CAUTION: Move the handle only when the green indicator light is on.
Moving the handle while the yellow light is on could damage the drive.
If all three lights blink rapidly at any time, a fault condition exists. Press
the Unload button once. If the fault is cleared, the tape unloads. The yellow
light blinks during unloading, then the green light comes on. If the fault

Operating the System Options

is not cleared, the three lights continue to flash. Do not attempt to use
the tape drive or to remove the tape cartridge. Call your Digital service
representative.
Use the following procedure to insert a tape cartridge (see Figure 3-6):
1. Pull the handle open.

2. Position the cartridge so the arrow on the cartridge faces left and points
toward the drive. Insert the cartridge into the TK70 tape drive until
you feel the cartridge lock into place.
3. Push the handle closed.
The green light goes off and the yellow light blinks as the tape loads.
When the yellow light glows steadily, the tape is ready to use.
NOTE: If the green light blinks rapidly when you push the handle
closed, the drive has detected a cartridge fault. Pull the handle open
and remove the cartridge. Use another cartridge.

Refer to Appendix C of this manual for instructions on how to create backup
files on a tape cartridge.
NOTE: If a cartridge is new, the drive performs a calibration sequence that
takes approximately 30 seconds when the drive receives the first command
from the operating system. The yellow light blinks rapidly and irregularly
during calibration.

3.1.3 TLZ04 Tape Drive
The TLZ04 tape drive is located behind the upper door of the system. To
use the drive, move the key to the top position and open the door.
The TLZ04 tape drive is a backup device that uses digital data storage
(DDS) and digital audio tape (DAT) recording technologies. Digital audio
tape, such as TLZ04 cassettes, takes advantage of the TLZ04 tape drive's
helical scan technology. This technology allows more data to be stored
on tape by recording data diagonally. DAT recording also minimizes
"crosstalk," providing you with higher data integrity.
Digital data storage uses a recording format that supports the use of digital
audio tape for computer applications. The DDSIDAT format allows you to
backup 1.2 gigabytes of data in approximately 2 hours with no operator
intervention. In addition, this format has three levels of error correction,
which ensures high data integrity.

3.1.3.5 Cleaning the Heads

Statistics show that over ninety percent of drive-related problems are
associated with the media. Therefore, Digital Equipment Corporation
strongly recommends that you follow the instructions for handling cassette
tapes and cleaning the heads of the drive.
This section shows you how to perform TLZ04 head cleaning. The heads
are the components, in a drive, that magnetically read and write data to
and from the media (in this case, a cassette tape).
NOTE: Digital Equipment Corporation recommends that you perform the
head cleaning procedure about every two weeks, or after every 25 hours of
drive usage.

Under normal conditions, it should not be necessary to exceed this cleaning
schedule. If a particular cassette causes problems, try changing to another
cassette.
CAUTION: Never attempt to clean the heads in a manner other than
described herein. Doing so will void the product warranty.

To clean the heads, use the head cleaning cassette as follows:
1. Observe that the drive indicator is lit solid green.

2. Insert the head cleaning cassette (part number TLZ04-HA) into the
drive as shown in Figure 3-11.
3. With the head cleaning cassette inserted, the drive automatically
cleans the head. The drive ejects the head cleaning cassette after
approximately 30 se~ondf!.
4. In the space provided. on the card enclosed with the head cleaning
cassette, place a check mark every time you use the head cleaning
cassette.
Under normal conditions, the head cleaning cassette performs for
approximately 25 cleanings. Additional cassettes are available from
your Digital sales representative or DECdirect.
If the head cleaning cassette has been used more times than it was
designed to be used, the drive will eject the cartridge in approximately
8 to 10 seconds. No cleaning action will occur.
CAUTION: Do not exceed the recommended 25 uses of the cleaning
cassette. After 25 uses, the cleaning cassette no longer cleans the heads.
You must use a new cassette.

3.2.2 Synchronous Controllers
The following synchronous controllers are available for your VAX 4000
system:
•

DPV11-Single-line programmable controller

•

DSV11-Dual-line controller

•

KMVlA-Programmable communications interface, Q-bus controller

Before using a synchronous controller you must verify the following:
•

The system you want to communicate with has an appropriate
synchronous controller.
Synchronous communications require a
synchronous controller on both the transmitting and receiving system.

•

Both the transmitting and receiving systems must have supporting host
software installed. Synchronous communications operate under specific
protocols that define how data is interpreted. Two common protocols
are X.25 and PSI. Appropriate host software is required to interpret
the protocol.

3.2.3 Network Controllers
NOTE: VAX 4000 systems contain an Ethernet controller embedded in the
CPU module. You can have a second optional Ethernet controller, the
DESQA module, included with your system.

Before using a network controller you must do the following:
1. Make sure the Ethernet cable (either standard transceiver cable or
ThinWire cable) is connected to the console module (or optional DESQA
module). The light next to the connector should be lit, indicating an
active connection. If not lit, move the Ethernet Connector switch to the
proper position.

3-28 VAX 4000 Model 300 Operation

2. Make sure the Ethernet cable is properly connected to the network. A
transceiver cable can be connected in one of the following ways:

•

To an H4000 or H4005 transceiver located on a traditional Ethernet

•

To a local network interconnect (DELNI), which can be connected
to a larger Ethernet or can serve to connect up to eight systems in
a local area network

A ThinWire cable can be connected as follows:
•

To a ThinWire Ethernet multiport repeater (DEMPR) or ThinWire
single port repeater (DESPR), which can be connected to a larger
Ethernet or can serve to connect many systems in a local area
network

•

To an available connection on a T-connector of other ThinWire nodes

3. Have the DECnet application installed on your system.
4. Register your node with the network manager so that your node is
recognized by other systems in the network.
Some software products, for example, Ethernet-based VAXcluster systems,
use the Ethernet hardware address of other systems to operate properly.
To find the hardware address of your Ethernet device, use the command
SHOW ETHER from console mode. The hardware address of your Ethernet
device displays on the terminal as shown in the following example:
»>SBOW E'l'BBRNE'I'

Appendix B

Programming Parameters for RF-Series
ISAs
This appendix describes the procedures for setting and examining
parameters for RF-series ISAs.
VAX. 4000 Model 300 systems have two DSSI host adapters built into the

CPU. Each host adapter provides a separate DSSI bus that can support up
to seven RF-series ISAs. The host adapters make a connection between the
CPU and the requested ISA on their respective DSSI bus. Each ISA has its
own controller and server that contain the intelligence and logic necessary
to control data transfers over the DSSI bus.
Four principal parameters are associated with each RF-series ISA:
•

ALLCLASS

•

UNITNUM

•

NODENAME

•

Bus Node ID

The ALL CLASS parameter determines the device allocation class. The
allocation class is a numeric value from 0 to 255 that is used by the VMS
operating system to derive a path-independent name for multiple access
paths to the same ISA. RF-series ISAs are shipped from the factory with
a default allocation class of zero. Each RF-series ISA to be served to the
cluster should have an allocation class that matches the allocation class
of the host system. Refer to the VMS VAXcluster manual for rules for
specifying allocation class values.
The UNITNUM parameter determines the unit number of the ISA. By
default, the ISA unit number is supplied by the bus node ID plug on the
ISA front panel. To set unit numbers and override the default values, you
use the console-based diagnostic and utility protocol (DUP) driver utility
to supply values to the UNITNUM parameter and to set a value of zero to
ISA parameter FORCEUNI.
The NODENAME parameter allows each ISA to have an alphanumeric
node name of up to eight characters. RF-series ISAs are shipped from the

Programming Parameters for RF-Series ISAs

B-1

factory with a unique identifier, such as R7CZZC, R7ALUC, etc. You can
provide a node name of your choosing if you prefer.
The Bus Node ID parameter is provided by the bus node ID plug on the
lSA front panel. Each DSSI bus can support up to seven lBAs, bus nodes
o through 6. Refer to Section 3.1.1 for instructions on changing bus node
ID plugs.
NOTE: All lSA parameters, with the exception of the Bus Node 1D, are
programmed and emmined usiT16 the console-based DUP driver utility. The
lSA Bus Node 1D is physically determined by the numbered bus node ID
plUII that inserts into the 1& front panel.

With an allocation class of zero, the operating system can use the default
parameter values to provide each ISA with a unique device name. The
operating system uses the node name along with the device logical name
in the following m~~er:
NODENAME$DIAu
where
NODENAME is a unique node name and u is the unit number.
With a nonzero allocation class, the operating system relies on unit number
values to create a unique device name. The operating system uses the
allocation class along with the device logical name in the following manner:
$ALLCLASS$DIAu
where
ALLCLASS is the allocation class for the system and ISAs, and u is a
unique unit number.
.
Using mass storage expanders, you can fill both DSSI busses (0 and 1),
giving a total of 14 RF-series ISAs. Each bus can have seven ISAs (bus
nodes 0-6). When devices are added to the second bus (bus 1), and your
system is using a nonzero allocation class. you need to assign new unit
numbers for ISAs on one of the busses. as the unit numbers for lSAs
throughout the system must be unique. The following table illustrates
the need to program unit numbers for a system using both DSSI busses (0
and 1). and a nonzero allocation class. In the case of the nonzero allocation
class. the operating system sees the ISAs as having duplicate device names.

The following instructions describe how to change ISA parameters using
the DUP driver utility. In the sample procedures, the allocation class will
be set to 2, the ISAs for bus 0 (in the VAX 4000) will be assigned new unit
numbers, and the system disk will be assigned a new node name.
Figure B-1 shows the DSSI busses and bus node IDs for an expanded VAX

lowercase letters. Unless otherwise instructed, type each command,
then press IR81Urnl.
Enter console mode as follows.
a. Set the Break EnablelDisable switch on the console module of the
VAX 4000 system to the enable position (up, position 1).
b. Set the power switch for each unit (both hosts for a dual-host
system, and any R400X expanders for expanded systems) to on (1).
Wait for the system to display the console prompt (»».
2. Make sure the lSAs for which you want to set parameters are on line
and are not write-protected. The RunlReady button should be in (lit).
and the Write-Protect button should be out (not lit).

3. At the console prompt, enter SHOW DSSI for a display of all DSSI devices
in your expanded system.
The firmware displays two lines of information for each ISA. The first
line contains the bus number, node number, and node name. The second
line contains the device name and unit number followed by the device
type in parentheses. The device name consists of the letters DIA or
DIB-devices on bus 0 are listed as DIA, devices on bus 1 are listed as
DIB. The DSSI host adapter for each bus is identified by an asterisk
(*).

In Example B-1, the system contains three RF71 ISAs (unit numbers
0-2), and the R400X expander contains seven RF71 ISAs (unit numbers
0-6).

In this example, each ISA will be assigned an allocation class of 2, and the
system disk will be given a new node name. When both DSSI busses (0
and 1) contain devices, and a nonzero allocation is used, each DSSI device
with the same allocation class must have a unique unit number. This is to
guarantee that all device names in the cluster are unique.

In this example, the ISAs in the VAX. 4000, DIAO, DIAl, and DIA2 will be
assigned unit numbers 10, 11, and 12.
Entering the DUP Driver Utility

To examine and change internal RF-series ISA parameters, you must first
activate the DUP driver utility by setting host to the specific ISA for which
you want to modify or examine parameters.
Use the command
SET HOST/DOP/DSSI/BOS : <BUS_NUMBER> <NODE_NUMBER> PARAMS

where
<bus_number> is the DSSI bus number (0 or 1). and <node_number> is the
bus node ID (0-6) for the !SA on the bus.

Appendix C

Backup Procedures
This appendix describes the following procedures:
•

Installing and booting standalone BACKUP on the system disk

•

Installing and booting standalone BACKUP on a TK50 tape cartridge

•

Backing up and restoring the system disk

C.1 Overview of Standalone BACKUP
The Backup Utility lets you create and restore backup copies of files,
directories, and user disks. Because the Backup Utility copies only what
is on the disk and ignores sections of any open files contained in memory,
you should use it to back up user disks, not the system disk. If you use
the Backup Utility to back up the system disk, the portions of the files that
were in memory and data about files not yet written back to the disk (cache)
will not be recorded on the resulting backup copy.
Use standalone BACKUP to make a complete backup of the system disk.
Standalone BACKUP is a version of the Backup Utility that runs without
the support of the entire VMS operating system. Before you use standalone
BACKup, you must shut down the VMS operating system. The shutdown
procedure sends the contents of the caches back to the disk and closes any
open files. By shutting down the system and using standalone BACKup,
you can make an exact copy of the system disk.
You can keep standalone BACKUP on the system disk, a TK50 tape
cartridge, or any other media the system supports. DIGITAL recommends
that you keep standalone BACKUP on the system disk and on a tape
cartridge.
Usually you boot standalone BACKUP from the system disk because it
saves time. You should, however, keep a copy of standalone BACKUP on a
tape cartridge in case the system disk becomes damaged.

Backup ~rocedures

C-1

C.1.1 Installing Standalone BACKUP on System Disk
You can install standalone BACKUP in any available root directory on
the system disk from [SYSI] to [SYSE]. However, Digital has established
[SYSE] as the standard directory for standalone BACKUP.
To install standalone BACKUP in [SYSE] on the system disk, use the

following procedure.
1. Log in to the SYSTEM account.

2. Enter the following command:
$ @SYS$OPDATB:STABACKIT SYS$SYSDBVIC8: I~~I

The procedure places the files in the directories [SYSE.SYSEXE] and
[SYSE.SYS$LDR] on the system disk. It lists the files as they are
copied. When the procedure finishes, the system displays the following
message:
The kit is complete.

3. To boot standalone BACKUP from the system disk, see Section C.1.2.

C.1.2 Booting Standalone BACKUP from the System Disk
To boot standalone BACKUP from the system disk, use the following

procedure.
1. If the VMS operating system is not running, go to step 2.

If the VMS operating system is running, enter the following command
to shut down the system:
$ @SYS$SYSTBM:SBOTD01IN lRetuml

Answer the questions. When the procedure asks if an automatic system
reboot should be performed, press Return for No. When the procedure
is finished, the system displays the following message:
SYSTEM SHUTDOWN COMPLETE - USE CONSOLE TO HALT SYSTEM

2. Stop the system by pressing the Halt button on the SCPo
3. Enter the BOOT command in the following format:
»> B/BOOOOOOO device_name IReturn I

Substitute the device name of the system disk for device_name. For
example, if the system disk has a device name of DIAO, enter the
following:

C-2 VAX 4000 Model 300 Operation

»> B/20000000 D~O I~NmI
4. Standalone BACKUP displays a message similar to the following:
VAX/VMS Version V5.3-2 Major version id = 1 Minor version id = 0

5. A few minutes later the procedure asks for the date and the time. Enter
the date and time using the 24-hour clock format, for example:
PLEASE ENTER DATE AND TIME (DD-MMM-YYYY HH:MM)
19-APR-1990 13:00 I~NmI

6. The system displays a list of the local devices on your system, for
example:
Available device MUAO:
Available device DIAO:

device type TK70
device type RF71

Check the list of devices. If the list is incomplete, make sure that all
the devices are connected properly to the system. See the VAX 4000
Model 300 Installation manual for details.
7. When standalone BACKUP finishes booting, it displays an identification message followed by the dollar-sign prompt ($):
%BACKUP-I-IDENT, stand-alone BACKUP V5.3--2; the date is
19-APR-1990 13:00:00.00
$

To back up the system disk, see Section C.2.1.
To restore the system disk, see Section C.2.2.

C.1.3 Installing Standalone BACKUP on a Tape Cartridge
If your system has a tape drive, Digital recommends that you keep
standalone BACKUP on a tape cartridge in case the system disk becomes
damaged. To install standalone BACKUP on tape cartridge, use the
following procedure.
NOTE: If you have a tape cartridge distribution kit, you already have
standalone BACKUP on a tape cartridge. If the original tape cartridge
becomes damaged, or if you need to make extra copies, use the procedure in
this section.
1.

Obtain a blank tape cartridge. Write the name on the paper label. For
example, you would use the name SfA BKUP V5.3-2 TK50 to build a
version 5.3-2 kit. Insert the label into the label slot.

Backup Procedures

C-5

8. When standalone BACKUP finishes booting, it displays an identification message followed by the dollar-sign prompt ($):
%BACKUP-I-IDENT, stand-alone BACKUP V5.3--2; the date is
19-APR-1990 13:00:00.00
$

9. Remove the tape cartridge containing standalone BACKUP from the
tape cartridge drive.

To back up the system disk, see Section C.2.1.
To restore the system disk, see Section C.2.2.

C.2 Backing Up the System Disk
There are several reasons to back up a system disk:
•

In case a problem occurs during a VMS upgrade or update, or during
the installation of other software prodllcts: Before you attempt any of
these procedures, you should back up the system disk. If a problem
occurs, you can restore the backup copy of the system disk.

•

To prevent loss of system files if they are deleted accidentally: After
you install or upgrade the VMS operating system, or any other software
products, you should back up the system disk. If a system file is deleted
and renders the system disk inoperable, you can restore the backup copy
and continue to use the system.

•

In case the system disk malfunctions: If you have a backup copy of
the VMS operating system, you can restore it to a functioning disk and
continue to use the system.

•

To eliminate disk fragmentation: Fragmentation happens when files
are not stored contiguously on the disk. Back up the system disk to a
tape cartridge, diskettes, or another disk. Then restore the files to the
original system disk. The BACKUP command creates a copy on which
files are stored contiguously.

Digital recommends that you use standalone BACKUP, which uses a subset
of Backup Utility qualifiers, to back up and restore the system disk. It is
especially important that you understand the functions of the !IMAGE and
!PHYSICAL qualifiers to the BACKUP command before using standalone
BACKUP.

C-6 VAX 4000 Mode\300 Operation

Table C-1 : Standalone BACKUP Qualifiers
Qualifier

Function

!IMAGE

Allows you to create a functionally equivalent copy of the entire
system disk

!PHYSICAL

Copies, saves, restores, or compares the entire system disk in
terms of logical blocks, ignoring any file structure

For a complete description of the Backup Utility and its qualifiers, see the
VMS Backup Utility Manual.

C.2.1 Backing Up the System Disk
To back up the system disk, use the following procedure:
1. Decide whether you want to back up the system to another fixed disk or
to a tape cartridge. If you are using a tape cartridge, obtain a scratch
tape that you can use for the backup copy. A scratch tape cartridge is a
tape cartridge that is either blank or contains files that you no longer
need.
2. If you are using a tape cartridge, write-enable it. To write-enable a tape
cartridge, slide the write-protect switch away from the tape cartridge
label. Insert the tape cartridge in the tape cartridge drive.
3. Determine the device name of the drive holding the system disk and
the drive holding the backup disk or tape cartridge. Enter the SHOW
DEVICE command at the console prompt (»».
4. Boot standalone BACKUP as described in Section C.1.2 or Section C.1.4.
5. Enter the BACKUP command in one of the following formats:
$ BACKOP/I~GE/VERIFY source_drive: target_drive:
$ BACKOP/I~GE/VERIFY source drive: target drive:-$ saveset .BCIt/LABEL--volume_Iabel/REWIND JR;tuml

IR.~rnl
I~wml

where:
•

source_ dr i ve is the location of the files that you want to back up.
Use the device name of the drive holding the system disk.

•

target drive is the destination. Use the device name of the drive
holdingthe backup disk or tape cartridge.

Backup Procedures

C-7

•

saveset.BCK is the name of the saveset (the name should reflect
the contents of the backup tape and cannot exceed 17 characters in
length).

•

volume label is the volume label of the tape cartridge in the tape
drive. if the tape has been initialized already, use the same volume
label that was assigned by the INITIALIZE command. If the tape
has not been initialized, you can assign a volume label at this time.
The volume label cannot have more than six characters.

The following example uses the BACKUP command to make a backup
disk. You can use a backup disk as the system disk:
$ BACKUP /IJIlAGB/V&P.IFY DIAO: DIAl IReturn I

The following example uses the BACKUP command to make a backup
tape cartridge. The contents of the backup tape cartridge must be
restored to a disk before you can use them. For more information,
see Section C.2.2.
$ BACKUP /ItfIAGB/V&P.IFY DIAO: MOAO: - IRetum I
-$ APR_lg_lgg0 • BCK/LABBL=l gAPRJ' /RBWINn IRetum I

6. The system displays the following message:
%BACKUP-I-STARTVERIFY, starting verification pass

7. If you are backing up the system disk to another disk, proceed to step

8.
If you are backing up your system disk to a tape cartridge and the
contents of the system disk fit on one tape cartridge, remove the backup
tape cartridge from the drive. Label the tape COMPLETE SYSTEM
BACKUP, number it, and include the date. Proceed to step 8.
If you are backing up your system disk to a tape cartridge and the
system disk contains more data than one tape cartridge can store, the
system displays the following messages:
%BACKUP-l-RESUME, Resuming operation on volume 2
%BACKUP-l-READYWRITE, Mount volume 2 on MUAO: for writing
Enter "YES" when ready:

Do the following:
a. Remove the backup tape cartridge from the drive.
h. Label the tape COMPLETE SYSTEM BACKup, number it, and
include the date.
c.

Write-protect the tape cartridge.

C-8 VAX 4000 Model 300 Operation

d. Write-enable another scratch tape cartridge and insert it in the
drive.
e. When you are ready to continue, enter Y (for Yes) and press Return.
The procedure displays the following message:
%BACKUP-I-STARTVERIFY, starting verification pass

Each time the procedure displays a mount request, follow steps
a through e.
8. When the procedure is finished, the system displays the following
message:
%BACKUP-I-PROCDONE, operation completed. Processing finished at
19-APR-1990 15:00:00.00
If you do not want to perform another standalone BACKUP operation,
use the console to halt the system.
If you do not want to perform another standalone BACKUP operation,
ensure the standalone application volume is online and ready.
Enter "YES" to continue:

9. Press the Halt button
10. Reboot the system.
Store the backup tape cartridge in a safe place.
NOTE: The BACKUP command creates a system disk that includes a
Digital-provided set of volume parameters including a CLUSTER_SIZE
(disk access scheme) of value 1. (The CLUSTER_SIZE parameter refers
to the way files are stored on the disk, NOT to VAXcluster environments.)
You can change most volume parameters later with the SET VOLUME
command. However to change the CLUSTER_SIZE parameter, you must
back up the system disk that has been initialized previously with the
CLUSTER_SIZE value that you want. 7b prevent the BACKUP command
from reinitializing the target disk, use the / NOINITIALIZE qualifier. For
more information about initializing a disk, see the Guide to Maintaining
a VMS System. For more information on the BACKUP command, see the
VMS Backup Utility Manual.

Appendix D

Removing Unwanted VMS Files
D.1 Using VMSTAILOR
Read this appendix if you want to remove the VMS operating system and
DECwindows files that you do not need from the system disk. For example,
if you are not running DECnet-VAX, you do not need the network support
files. You can remove unwanted files with the VMSTAILOR program. Enter
the following command to log in to the SYSTEM account:
$ RON SYS$UPDA'l'B: VNS'l'AILOR

IReturn I

The VMSTAILOR program asks you if you want to tailor files ON or OFF.
Type OFF to remove unwanted files.
CAUTION: Do not delete files from the factory-installed software (FIS)
system until you have backed up your software. A VMS distribution
kit is needed to return files to the system disk. Also, VMSTAILOR and
DECW$TAIWR procedures cannot restore files from a backup set. It may
be necessary to reload the system software from a backup set if files are
incorrectly deleted and if a VMS distribution kit is not available.

The VMSTAILOR program lists each group of files and its size in blocks.
Files are grouped according to their function. For example, all the files
required for cluster support are in one group. A file group is made up of
many small subgroups. You can eliminate an entire group of files, or you
can eliminate one or more of its subgroups.
Decide which file groups or subgroups you do not need to support your
system. The VMSTAILOR program displays step-by-step instructions that
are easy to follow.
VMSTAILOR displays the names of the files it deletes. After it finishes,
AUTOGEN runs automatically to make the adjustments that are necessary
after system files are deleted.
NOTE: You can use VMSTAILOR at any time to delete or add groups of
VMS files to the system disk. After adding files to the system disk, you
should apply any updates that affect them.

Removing Unwanted VMS Files

0-1

For example, suppose you do not need the VMS Version 5.0 MAIL utility
and you run VMSTAILOR to remove those files. Later on, if you decide
you want to use mail, you can run VMSTAILOR to return the MAIL files
to the system disk. You then apply any VMS upgrade or update that has
occurred since Version 5.0 that affected the MAIL utility. To remove VMS
DECwindows files from the system disk, enter the following command:
$ RON SYS$OPDA'fB:DBCW$TAILOR IRetuml

The DECW$TAILOR program works just like the VMSTAILOR program.
