VAXft System
The VAXft system is a fault-tolerant VAX computer that provides high
levels of availability and reliability for a variety of applications. Hardware
redundancy and failover techniques ensure uninterrupted operation in
the event of a single point of failure anywhere in the system. Modular
components simplify repair and maintenance procedures, reducing the
time required to bring components back into service.
The VAXft system:
•

Operates as a stand-alone system or as the boot or satellite node for a
local area VAXcluster configuration.

•

Has expansion capabilities in the areas of main memory, input/output
(I/O) devices, synchronous communications adapters, and disk storage.

1–2 VAXft System

1.1 Fault-Tolerant Operation
The VAXft system achieves fault tolerance through a combination of
redundancy and failover techniques. All critical functions of the VAXft
hardware are duplicated.
The VAXft system has two zones. Each of the zones contains the
hardware required to execute an application. The two zones are identical
in configuration, except in cases where the customer chooses not to have
hardware redundancy. The zones are physically and logically connected,
and simultaneously process the same instructions. When both zones
operate in this synchronous manner, they perform as a single, faulttolerant system. If a single hardware fault occurs in a component in
either zone, the problem is communicated to the other zone.
Once the fault is ‘‘known’’ within the system, the system takes action to
isolate the faulty component. This action can be:
•

Disabling an I/O path

•

Removing an element from service (for example, a memory module)

•

Removing an entire zone from service

Despite the nature of the failure and recovery action, the system is able
to remain in full operation.
A simplified representation of the two zones is shown in Figure 1–1.

Model 610 and 612 base systems

•

Model 610 and 612 systems with expansion

The VAXft model 110, 310 and 410 systems are configured as pedestal or
rackmount systems.
NOTE
The system cabinet is the pedestal package.
Each pedestal is 68.6 cm (27.0 in) high by 53.3 cm (21.0 in) wide. The
VAXft 110 system has two zones enclosed in one cabinet, which is similar
to a BA213 cabinet.
A model 310 or 410 base system has two system cabinets. Each system
cabinet includes power supplies, cooling, logic modules, and two storage
slots. Thus, a model 310 or 410 base system has four storage slots. One
of the four storage slots may house a TF70 tape drive.
The tape drive can be used for loading software. It can also be used as a
backup device. The other three storage slots can be used for disks, or if
desired, each zone can house one disk and one tape. RF-series disks are
used.
A model 310 and 410 system with expansion has two system cabinets
and two expander cabinets. Each system cabinet is connected to both
expander cabinets.
An expander cabinet has seven storage slots, six of which can be used.
One expander cabinet may house a TF70 tape drive in one of the storage
slots. Each expander cabinet can house up to six fixed disk drives or five
fixed disk drives and a removable tape drive or a removable disk drive.

VAXft System

1–5

The VAXft model 610 and 612 systems are 152.4 cm (60.0 in) cabinets.
Each cabinet contains two zones (upper and lower). A model 610 base
system has one cabinet. Each zone enclosure houses power supplies,
cooling, logic modules, and four storage slots. A base cabinet has two
additional storage slots. One of the six storage slots may house a TFseries tape drive.
Customers needing more storage space can order a model 610 system
with one or two expander cabinets. Each expander cabinet contains power
supplies, cooling, and more storage slots.
Also available to customers are the model 612 base system and systems
with expansion. A model 612 base system has two system cabinets and
one expander cabinet. A model 612 system with expansion has two
system cabinets and two expander cabinets. These configurations allow
more processing power and storage space than the model 610 system
configurations.

1.3 Model 110 System Description
This section describes the model 110 base system.

1.3.1 Model 110 Base System
Figure 1–2 shows the front view of a base system with VT-series video
terminals as the local console terminals. Terminals used in console
applications may be hard copy, video, or video with printer. A variety of
video terminals and printer stands are available.
The model 110 is similar to the model 310 system, but is housed in one
cabinet. It has less expandability in terms of memory, disk capacity, and
available module options.
The VAXft model 110 system is available as a pedestal (Figure 1–3) or
rackmount (Figure 1–4) system. The rackmount system is the pedestal
system without the plastic cover and casters. It can be installed in a
standard 19-inch RETMA1 rack cabinet.

RETMA rack cabinets are used by Digital and other major manufacturers of
electronic equipment. The cabinet rails, mounting hole patterns, and spacing
conform to international standards that allow compatibility with products
manufactured by Digital and other major manufacturers.

The media storage used in the model 110 can include the following storage
devices:
•

TK70 tape drive

•

RF-series disk drives

The media storage in zone A can have up to two RF72 or three RF31 disk
drives. The media storage in zone B can have one TK70 tape drive and
either one RF72 or two RF31 disk drives. If a tape drive is not necessary
in zone B, then zone B can have two RF72 or three RF31 disk drives.
For memory shadowing, each zone must have the same number of storage
devices. The maximum is three storage devices in each zone.
The TK70 tape drive can serve as a system software load device as well as
a backup device. The RF-series disk drives can be used as data backup,
software load, or bootstrap devices.
Each zone contains a logic backplane with five slots. The following
three modules are the minimum required in each backplane for system
operation:
•

One MS520 memory module

•

One KA510 processor module

•

One KFE52 system I/O controller module

Each module has a dedicated slot in the backplane.
The MS520 memory module provides 32 MB of main memory with error
correction code (ECC).
The KA510 processor module executes the VAX native instruction set.
Each processor module operates with a pair of synchronized processors.
The processor modules in each zone are connected through a pair of
cross-link cables that provide interprocessor communications.
The KFE52 system I/O controller module supports:
•

An expandable DSSI bus for the system storage devices

•

Two serial ports for the local and remote console terminals

•

An Ethernet interface for either a ThinWire or traditional (thickwire)
network interconnect (NI) link

1–10 VAXft System

Each backplane has two additional slots that may contain up to two
additional MS520 memory modules, up to two wide area network (WAN)
communications adapters, or an additional KFE52 system I/O controller
module.
The WAN communications adapter provides two synchronous
communications lines. These lines can be connected redundantly between
two zones using external cabling and circuitry.
Figure 1–5 shows the correct placement of the logic modules in the
backplane of a zone. Table 1–1 describes the logic modules. The number
of memory modules must be the same in both zones.

The power system for each cabinet consists of two packages: ac power
input box and dc power supply. The ac power input box converts its input
to unregulated dc.
The dc power supply supplies regulated dc power to the logic modules and
storage elements in the system cabinet. A battery backup unit, which is
comprised of batteries, can supply the system cabinet with dc power for
at least 30 minutes on a full charge. Further information on the power
modules can be found in Chapter 2.
Each system cabinet contains a logic backplane with seven slots. The
following three modules are the minimum required in each backplane for
system operation:
•

One MS520 memory module

•

One KA520 (model 310) or KA550 (model 410) processor module

•

One KFE52 system I/O controller module

Each of the above modules has a dedicated slot in the backplane.
The MS520 memory module provides 32 MB or 64 MB of main memory
with error correction code (ECC).
The KA520 or KA550 processor module executes the VAX native
instruction set and incorporates an integral cache memory and floatingpoint accelerator. Each processor module operates with a pair of
synchronized processors. The processor modules in each zone are
connected through a pair of cross-link cables that provide interprocessor
communications.
The KFE52 system I/O controller module supports:
•

An expandable Digital small storage interconnect (DSSI) bus for the
system storage devices

•

Two serial ports for the local and remote console terminals

•

An Ethernet interface for a ThinWire or traditional (thickwire)
network interconnect (NI) link

Each backplane has four additional slots that in a base system may
contain up to three additional MS520 memory modules, up to four wide
area network (WAN) communications adapters, or an additional KFE52
system I/O controller module for connection to a second Ethernet or to
support storage expansion.

VAXft System

The WAN communications adapter provides two synchronous
communications lines. These lines can be connected redundantly between
two zones using external cabling and circuitry.
Figure 1–8 shows correct placement of the logic modules in the system
backplane. Table 1–2 describes the logic modules. The number of memory
modules must be the same in both system cabinets.

A system with expansion offers increased storage over a base system.
The system cabinets are interconnected just as in a base system. The
connections between the system cabinets and expander cabinets are made
using cables between the system I/O controller modules in the system
cabinets and the DSSI bus in the expander cabinets.
In a system with expansion, all drives must be mounted in the expander
cabinets. The system cabinet in a system with expansion contains no
disks or tapes. One to six storage devices can be housed in the expander
cabinet.
One expander cabinet may contain a cannister tape drive in the cannister
slot as a software installation and backup device. The other expander
cabinet may contain a:
•

Removable cannister tape drive in the cannister slot

•

Removable cannister disk drive in the cannister slot

•

Nonremovable carrier disk drive in the top left carrier slot

All cannister drives are removable and shock mounted for portability.
Cannister disk drives may be removed and stored for backup purposes.
An unused cannister slot requires a TM002 blank cannister module (PN
70-27929-01) to maintain cooling airflow inside the cabinet. Unused
carrier slots require a TM003 blank carrier module (PN 70-27928-01).
Appendix C describes how to remove and replace a cannister or carrier
drive.
The ac power input box and dc power supply in an expander cabinet
perform the same functions as in the system cabinets. The system
cabinets of a system with expansion must have four modules:

1.6 System Architecture
All the memory, processing, and I/O facilities shown in Figure 1–21 are
provided in two interconnected system cabinets in a base system.
During normal operation, both zones operate in lockstep. While operating
in lockstep, there is no single point of hardware failure. An error in one
zone will not disable the VAXft system.
When a solid hardware failure occurs, the zone with the failing component
is brought off-line for repair. When the repair is completed, the zone is
powered on and the VAXft system automatically resynchronizes with
the operating zone, restoring redundancy. This process is transparent to
applications running on the VAXft system.

removable cannister module.
The TF70 cannister tape drive may be used for:
•

Installing or updating the operating system

•

Installing or updating user software

•

Storage and retrieval of archived information

Two switches are located on the TF70 cannister, the power switch and the
server setup (SU) switch.
•

The power switch controls power to the drive. The switch must be set
to off (0) before you remove the cannister from the system. It must
also be set to off (0) when you insert the cannister in the system.

•

The server setup (SU) switch allows you to set the DSSI parameters
for a drive you are installing in a running VAXft system. It has no
effect when the system is halted.
The server setup switch must be pressed in and held while you power
on: a new drive or a drive you are returning to the system after
repair. The switch has no other function; use of the switch at any
other time has no effect. After setting DSSI parameters under the
DUP facility, power off the drive; then power on the drive without
using the server setup switch. For further information on drive DSSI
parameters and the DUP facility, refer to the BOOT command syntax
(Section 4.4), BOOT command description (Section 5.2), and the RBD
command description (Section 6.8).

A magnetic fault indicator (MFI) is located on the cannister. This
indicator shows yellow when a failure is detected in the tape drive. A
fault may be detected at power-on or during operation. Upon successful
completion of the power-on diagnostics, the indicator is blank (not yellow).
For more information on the TF70 cannister tape drive, see Appendix A.
Removal and replacement procedures and the use of the server setup
switch are covered in Appendix C.

2–6 System Components

2.3 TF857 Tape Subsystem
Figure 2–3 shows a front view of the TF857 tape subsystem.
The tape unit is mounted with its associated controller inside a removable
module.
The TF857 tape subsystem can be used for:
•

Installing or updating the operating software

•

Installing or updating the user software

•

Storage and retrieval of archived information

The Mode Select key (Figure 2–3) can lock the loader transfer assembly
into the enclosure, as well as lock the receiver closed. It has four modes:
•

OCP Disabled

•

2.7 Power Modules
Figure 2–7 shows a front view of the power modules located in the model
110 cabinet. Figure 2–8 shows a front view of the power modules located
in each model 310 and 410 cabinet. Figure 2–9 shows a front view of the
power modules located in each model 610 and 612 cabinet.
The VAXft power system consists of the following modules:
•

AC power supply (model 110 only)

•

AC power input box

•

DC power supply

•

Battery pack

•

AC distribution box (model 610 and 612 only)

The H7868 ac power supply provides unregulated direct voltage to the
internal power bus. The ac power input box accepts 115 Vac (nominal) or
230 Vac (nominal) at 47 to 63 Hz from the cabinet line cord.
The H407-A ac power input box provides an unregulated direct voltage of
48 Vdc to the internal power bus. The ac power input box accepts 115 Vac
(nominal) or 230 Vac (nominal) at 47 to 63 Hz from the cabinet line cord.
An input voltage selector switch located on the ac power transformer
selects one of the voltage ranges. The VAXft Systems Site Preparation
and Installation Guide (EK-VXFT1-IN) provides the procedures needed
to check or change the switch position. The power breaker switch for the
cabinet is located on the front of the ac power input box. The magnetic
fault indicator (MFI) on the front of the box shows yellow when a fault is
detected. One of the following faults is most likely:

The H7233 dc power supply converts the 48 Vdc unregulated power to
regulated voltages used within the VAXft cabinets. Table 2–1 lists the
dc voltages required by the VAXft components. The H7233-AA dc power
supply is used in the system cabinet. The H7233-AB dc power supply is
used in the expander cabinet. The system dc power supply regulates the
voltages required for the system logic, storage, and cooling elements. The
dc power supply has a magnetic fault indicator (MFI) on the front of the
box. The magnetic fault indicator shows yellow when a fault is detected.
One of the following faults is most likely:
•

PCIM logic

•

Logic regulator

•

Disk regulator

•

Cooling fan

Within the dc power supply is a power and cooling intelligence module
(PCIM). It monitors the power system and cooling system inside the
cabinet and communicates with the operating system. When a power or
cooling problem occurs, the operating system is informed, so it can take
appropriate action.
Each of the VAXft cabinets has a battery pack that typically provides
about ½ hour of power to the cabinet during ac power outages. Thus,
during a power outage, the VAXft system can be shut down after
completion of all outstanding transactions and processes. The PCIM
also tracks the operation of the battery and notifies the operating system
when the battery is:
•

Active due to ac power outage

•

Charging

The dc power supplies used in the VAXft system contain a right and a left
regulator that supply two separate sections of the cabinet. Table 2–1 lists
the dc power available to the internal system cabinet components from
the H7233-AA dc power supply. One regulator supplies the logic power.
The other regulator supplies power to the disk drives and fans. In the
expander cabinets, each of the two regulators in the H7233-AB dc power
supply provides power to the disk drives and fans.

2.9 Cabinet Cooling System
Figure 2–12 shows the airflow pattern for the model 110 cabinet.
Figure 2–13 shows the airflow pattern for each of the cabinets in the
model 310 and 410 system. Figure 2–14 shows the airflow pattern for
each of the cabinets in the model 610 and 612 system.
The cabinets are continuously cooled by two variable-speed dc fans, one in
the left side and one in the right side of each cabinet (Figure 2–8). The
speed of the fans is based on the ambient temperature of the cabinet as
determined by thermal sensors. The thermal sensor output is issued to
the PCIMs, which control the speed of the fans.
When the magnetic fault indicator on the cooling fan panel shows yellow,
one of the following conditions is likely:
•

Cooling fan is stopped.

•

Cooling fan is running at less than 20% of the speed of the fan located
in the dc power supply.

The fans direct the airflow in the cabinet. The system must rest on a firm
surface to maintain cooling airflow.

NOTE
The focus of this chapter is model 310, 410, 610, and 612 systems.
If you own a model 110 system, keep in mind the following:
•

An expanded system is always a model 310, 410, 610, or 612
system.

•

A dual cabinet system is always a model 310, 410, 610, or 612
system. In a model 110 system, the two zones are housed in a
single cabinet.

•

The Local Console Disable switch is present on model 310, 410,
610, and 612 systems. In a model 110 system, the consoles are
always enabled.

4–2 Console Operations

4.1 Console Description
The VAXft system supports a local console terminal in each zone as shown
in Figure 4–1. Console firmware (console programs located in ROM)
resides on the primary system I/O controller module and on the processor
module in each system cabinet.

Console Operations 4–3

An optional remote console terminal may be connected to each zone. The
remote console terminal and the local console terminal are connected to
the zone through the primary system I/O controller module. The primary
system I/O controller module is located in slot 2 of the module card cage in
model 310, 410, 610, and 612 systems. The primary system I/O controller
module is located in slot 1 in each zone of the model 110 system.
Table 4–1 describes the function of each component of the VAXft console.
Table 4–1 VAXft Console Parts
Part

Function

Local console terminal

Terminal located with the system that is used for
console input and display output.

Remote console port

One remote port is available in each zone. The
port may be connected to a remote console terminal
through a modem. The remote console port provides
the same functions as the local console port.
If connected through a modem, the remote port may
serve as a dial-in port for the user or as a dial-out
port for the autonotification process.

Console firmware

The VAXft console firmware resides on the primary
system I/O controller module and on the processor
module.

It is best to use only one of the four possible console terminals for input
commands at any given time. All of the console terminals echo the
response of the system to a console command.
When the VAXft system is operating with only a single zone, the local or
remote console terminals connected to the operational zone are used as
the input devices.

4–4 Console Operations

4.2 Console Operating Modes
Console operators communicate with the system in one of the three
input/output (I/O) operating modes shown in Figure 4–2.

Console Operations 4–5

The three console operating modes are:
•

Program I/O mode (PIO mode)

•

Console I/O mode (CIO mode)

•

Module I/O mode (MIO mode)

Normal operation takes place in the PIO mode. The CIO and MIO
modes are used by system managers to control the system and to set the
operating parameters.
PIO mode allows the operator to use the console terminal. Specifically, in
PIO mode the operator can use the VAXft console terminal to log in, use
the mail facility, create and edit files, and do other types of work typically
done from a user terminal.
PIO mode can be entered from either of the two other console operating
modes. To transition the console into PIO mode, use one of these console
commands: SET TERMINAL PROGRAM or PIO.
CIO mode allows the operator to execute the VAXft console commands.
These commands are a subset of the VAX–11 console command language
and include the VAXft specific commands. The CIO commands are
described in Chapter 5 of this manual.
To transition from PIO mode to CIO mode, be sure the Local Console
Disable switch on the summary panel is released (button out). Then
press the Break key on the console terminal once. Be sure you press the
Break key once only. By pressing the key more than once, you will enable
baud-rate cycling (Section 5.11.2, SET PORT).
MIO mode is used to set or change console parameters involving the
primary system I/O controller module. The only way to enter MIO mode
is by using the MIO command from CIO mode. While in MIO mode, the
VAXft operating system may be running or halted. A complete listing of
the MIO commands is provided in Chapter 6 of this manual. The CIO
or PIO mode can then be entered from MIO mode using the CIO or PIO
command.

4–6 Console Operations

4.3 Console Control Characters
The ASCII control characters and function keys listed in Table 4–2 have
special meanings when typed on a console terminal running in CIO or
MIO mode.
Table 4–2 Console Control Characters and Function Keys
Character/Key

Function

Break

Causes the console to exit PIO mode and enter CIO mode.
First, be sure the Local Console Disable switch on the
summary panel is released (button out). Then press the
Break key on the console terminal.

Ctrl/C

Echoes ^C and causes the console to abort processing of a
command.

Ctrl/O

Alternately enables and disables console output to the
terminal.

Ctrl/R

Echoes ^R and retypes the command line.

Ctrl/S

Stops console transmission to the terminal until Ctrl/Q is
typed.

Ctrl/Q

Resumes console output previously suspended by Ctrl/S .

Ctrl/U

Echoes ^U and erases the command line.

Esc or Ctrl/[

Disables the meaning of the next character you type. This
function is keyboard dependent. Refer to your terminal
owner’s manual.

Ctrl/P

Exits the z mode and returns to the CIO mode.

Return

Terminates a command line and executes the command.

<x (delete)

Deletes the character to the left of the cursor. On a hardcopy terminal, use the rubout key. Refer to your terminal
owner’s manual.

Break Break

Enables autobaud.

Console Operations 4–7

In PIO mode, the Break key causes the console to exit PIO mode and enter
CIO mode (if the Local Console Disable switch is not enabled). In CIO
or MIO mode, Break is the equivalent of Ctrl/C and is echoed as ^C. If
issued from a remote console terminal without full privileges, the break
character is passed to the operating software like any other character.
(For a remote operator to use CIO mode, full privileges must be set by the
local operator.)
Ctrl/C echoes ^C and aborts the processing of a command in progress. To
ensure the abort, you may need to press Ctrl/C twice.
Ctrl/O alternately enables and disables console output to the terminal.
When the output is disabled, the console echoes ^O and ignores further
software transmissions. Console output may also be reenabled using the
Break key or Ctrl/C .
Ctrl/R echoes ^R and retypes the command line. This feature is useful
when editing a command line on a hard-copy terminal.
Ctrl/S stops console transmission to the terminal. Ctrl/Q resumes a console
transmission previously stopped by Ctrl/S .
Ctrl/U echoes ^U and erases all characters previously typed on the
command line.

The Esc (Escape) key or a Ctrl/[ (control/left bracket) disables the meaning
of the next character typed, allowing a control character or special
character to be included in the command line. Refer to your terminal
owner’s manual.
Ctrl/P changes the console from the z mode to the CIO mode.

The Return key terminates a command line. Pressing Return enters the
command line and invokes the command function. By typing Ctrl/U or
Ctrl/C before you press Return , you cancel the command and erase the
command line.
The <x (delete) key deletes the last character typed. On a hard-copy
terminal, the rubout key functions the same way. Refer to your terminal
owner’s manual.

4–8 Console Operations

4.4 Console Command Language Syntax
The console commands accept qualifiers. A qualifier is used to specify a
numerical value or to select an option from a list of options. Command
elements may be abbreviated and any extra tabs or spaces are ignored.
Unless otherwise noted, numerical values must be given in hexadecimal
(hex) notation. The command length may not exceed 80 characters.
Table 4–3 lists the console command language syntax rules. The console
commands available for the VAXft system are listed in Chapter 5 and
Chapter 6. The console command language syntax rules are valid for the
commands listed in those chapters.
Table 4–3 Console Command Language Syntax
Command Element

Rule

Abbreviations

A command verb or argument may be abbreviated
to the extent that it remains unique.

Multiple adjacent spaces
and tabs

Are treated as a single space.

Qualifiers

May appear after a command verb, option, or
symbol. They must be preceded by a slash (/).

Numbers

Must be hexadecimal (hex).

No characters

Are treated as a null command. No action is taken.

Console Operations 4–9

Commands, qualifiers, and options may be shortened. However a
minimum number of characters (enough to uniquely identify the command
keyword) must be entered. At the beginning of Chapters 5 and 6 of this
manual, console abbreviations are shown in bold capital letters.
Qualifiers may be used after the command keyword or after any symbol
or number in the command. Each qualifier must be preceded by a slash
(/). Spaces are allowed before a slash, but no spaces are allowed between
a slash and the qualifier.
Comments are allowed on a command line. Comments, or characters
following an exclamation point (!), are ignored by the console when the
Return key is pressed. This feature is useful when you document a console
session on a hard-copy terminal.
Uppercase or lowercase characters may be used for the command input.
A command line with no characters is a null command. If you press the
Return key, the console takes no action.

4–10 Console Operations

4.5 Bootstrap Procedures
The BOOT command initializes the system and then loads and starts the
virtual memory bootstrap (VMB) program from read-only memory (ROM).
The VMB program, in turn, loads and starts the operating system from
the specified boot device. Figure 4–3 and Table 4–4 show the steps in the
boot procedure.

Procedure

The operator enters the BOOT command at the console terminal,
which is in CIO mode. The operator may use device specifiers with
the BOOT command to select one or more boot devices of the same
type.

The system enters a reset procedure that initializes all system
components.

The BOOT command loads and starts the VMB program from the
specified boot source.

VMB loads and starts the operating system.

Boot Devices
The VAXft system may be booted from the following types of boot devices:
•

TF-series tape drives

•

RF-series disk drives

•

Boot sources available over an Ethernet

CAUTION
You cannot boot the system from the remote console. The
KFE52 I/O module is reset when the system boots, and this reset
disconnects the modem.
VMB
The VMB program is the primary bootstrap program. It is stored in ROM
in the VAXft system.

has established a boot name using the SET BOOT name command.

Console Operations 4–13

4.7 Boot Devices and Module Expansion
For a complete description of the commands to determine the
configuration of the disks in the system, see Section 6.8, RBD.
The device specifier shown in Figure 4–4 takes the form ddan where:
•

dd specifies the device type
MI is a TF-series tape drive
DI is an RF-series disk drive
EP is an Ethernet port

•

a specifies the zone and slot of the primary or secondary system I/O
controller module. Figure 4–5 shows this for the model 110 system.
Figure 4–6 shows this for the model 310, 410, 610, and 612 systems.
Figure 4–6 also lists the correct module expansion sequence.

•

n specifies the decimal unit number of the boot device. If FORCEUNI
is set to 1 on a particular system drive, n specifies the DSSI node ID
number selected by the backplane.

If the FORCEUNI parameter is set to 0 in all system drives, the device
specifier ddan must specify the device unit number stored in the drive.
The RBD command description in Chapter 6 provides information on
setting the drive parameters.
You may specify as many as four paths to one or more of the same type
of device (see variation 2). The boot procedure then tries one or more of
the specified boot paths. Remember, the specifiers must be separated by
commas.
Chapter 5 provides more information on the BOOT command. Section 5.2
provides the BOOT command parameters and VMB program flags.
Section 5.11.1 explains how to store up to ten boot commands with
symbolic names.

CIO Mode Console Commands
This chapter describes the console commands available when the console
is in the console I/O (CIO) mode.
To recognize and process most CIO commands, the operating software
must be halted and the processor must be running the console firmware.
Certain CIO commands may be executed when the operating software
is not halted. These commands are: MIO, PIO, SET PORT, SET
TERMINAL, and SHOW PORT. This chapter includes:
•

Entering CIO mode

•

CIO mode console commands:

5–2 CIO Mode Console Commands

NOTE
The focus of this chapter is model 310, 410, 610, and 612 systems.
If you own a model 110 system, keep in mind the following:
•

An expanded system is always a model 310, 410, 610, or 612
system.

•

A dual cabinet system is always a model 310, 410, 610, or 612
system. In a model 110 system, the two zones are housed in a
single cabinet.

•

The Local Console Disable switch is present on model 310, 410,
610, and 612 systems. In a model 110 system, the consoles are
always enabled.

5.1 Entering CIO Mode
Using the example as a guide, follow the numbered steps to enter CIO
mode. A remote operator can use CIO mode only when full access
privileges for the remote console have been set at the local console.
Example
$
Break
$
>>> HALT
?002 External halt
PC = 01E01473
>>>

>>> CONTINUE
>>> PIO
$

! From PIO mode, release the Local Console
! Disable switch (button out). Press the
! Break key. Halt the processor. Be sure
! you press the Break key once only.
!
! Begin your console session in CIO mode.
.
.
.
! After completing your console session,
! you may continue, start, or boot the
! system. If you continue, entering the
! PIO command returns you to PIO mode and
! issues the DCL $ prompt.

Comments are allowed on a command line. Comments, or characters
following an exclamation point (!), are ignored by the console when the
Return key is pressed. This feature is useful when you document a console
session on a hard-copy terminal. The terminal mode change commands
are listed in Table 5–6.

CIO Mode Console Commands 5–3

To enter and use CIO mode:
1. Your console terminal is connected to a system cabinet. While still
in PIO mode, check the summary panel on that system cabinet.
Make sure the Local Console Disable switch on the summary panel is
released (button out, LED not lit).
2. Press the Break key to leave PIO mode. When the console enters CIO
mode it returns the >>> prompt.
3. Enter the HALT command before using the CIO mode commands. If
you do not halt the processor, the console returns an error message.
4. To return to PIO mode, enter one of these commands: SET
TERMINAL PROGRAM or PIO.
Chapter 4 provides more information on use of the various console
operating modes.
Some commands controlling the terminal ports on the primary system
I/O controller module (SET PORT and SET TERMINAL PROGRAM) are
recognized in CIO and MIO modes. MIO commands may be used with the
processor running or halted and are described in Chapter 6.

5–4 CIO Mode Console Commands

5.2 BOOT
The BOOT command initializes the system and then loads and starts the
virtual memory bootstrap (VMB) program from ROM. The VMB program,
in turn, loads and starts the VMS operating system.
CAUTION
You cannot boot the system from the remote console. The
KFE52 I/O module is reset when the system boots, and this reset
disconnects the modem.
Examples
1.

>>> BOOT MIA5

! Zone A boots from TF70 tape drive
! unit 5 through the primary system
! I/O controller module.

>>> BOOT DIA0

! Zone B boots from RF-series disk drive
! unit 0 through the primary system
! I/O controller module.

>>> BOOT TAPE

! Boots from the stored boot command
! called TAPE that was created by the
! SET BOOT command.

>>> BOOT

! Boots from the stored boot command
! called DEFAULT that was created by
! the SET BOOT command.

>>> BOOT DIA0, DIG0, DIB6, DIF6
! Boots from the first RF-series disk
! drive found in zone A or B.

>>> BOOT EPA0, EPF0
! Boots from the first responding
! Ethernet device requested by
! zone A or zone B.

The BOOT command syntax is:
B[OOT] [/qualifier] [device list] [/qualifier]

or
B[OOT] [name]

CIO Mode Console Commands 5–5

Specification of the boot device is optional. The boot device is used to
identify the path(s) to the boot device(s). Specify as many as four paths
to one or more of the same type of device. Commas are used to separate
these device specifiers.
The boot device takes the form ddan where:
dd specifies the device type, which could be one of the following:
MI is a TF-series tape drive
DI is an RF-series disk drive
EP is an Ethernet port
The usage of a and n depends on the system DSSI configuration and
storage device settings. Sections 4.6 and 4.7 explain the boot device
specifier usage when the FORCEUNI value is 1 in all storage devices.
Section 6.8 explains the boot device specifier usage when the FORCEUNI
value is 0 in all storage devices.
The qualifier field is optional and may be used before or after the boot
device(s). Table 5–1 describes the /R5:n qualifier and Table 5–2 lists the
VMB program control flag values for n.
The switch R5 is used to pass boot parameters to the VMB program. If
the BOOT command is used without arguments, the stored boot command
is used. Section 5.11.1 explains how to name and store boot commands
with preset values.
The name specifier is used by itself to invoke a stored boot command. It
must be a 1- to 4-character symbolic name.

CIO Mode Console Commands 5–7

5.3 CONTINUE
The CONTINUE command resumes execution from the point where the
system halted.
Example
>>> CONTINUE

! Resumes execution of the system.

The CONTINUE command syntax is:
C[ONTINUE]

When the CONTINUE command is issued, the console reloads the context
saved by the HALT process (PC, PSL, GPRs, and memory management).
The processor resumes program execution at the address held by the PC.
The console terminal remains in CIO mode.

5–8 CIO Mode Console Commands

5.4 DEPOSIT and EXAMINE
The DEPOSIT command stores the specified data in the specified address.
The EXAMINE command displays the data stored in the specified
address.
Examples
1.

>>> D /L /P 27 0
CTB0: D /L /P 27 0

! Deposits a longword value of 0 in
! physical address 27.

>>> E /L /P 27
! Displays the longword value stored
CTB0: E /L /P 27
! in physical address 27.
P 00000027 00000000

The DEPOSIT command syntax is:
D[EPOSIT] [/qualifier] address data [/qualifier]

The EXAMINE command syntax is:
E[XAMINE] [/qualifier] address [/qualifier]

A qualifier may be placed before or after the address and data specifier.
Tables 5–3 and 5–4 describe qualifiers used with the DEPOSIT and
EXAMINE commands.
The address specifier identifies either the physical or virtual hex memory
address for a DEPOSIT or EXAMINE.
The data specifier identifies the hex data to be stored by a DEPOSIT.
When the system is initialized, or when any transition from a running to
a halted state occurs, the default physical address space (0) and data size
(longword) are used.

CIO Mode Console Commands 5–9

Table 5–3 DEPOSIT and EXAMINE Command Data Size Qualifiers
Qualifier

Function

Sets the data size to byte.

Sets the data size to word.

Sets the data size to longword.

Table 5–4 DEPOSIT and EXAMINE Command Address Space Qualifiers
Qualifier

Function

Sets physical address space.

Sets virtual address space. An EXAMINE to virtual
memory returns the translated physical address. A
DEPOSIT to virtual memory sets the PTE <M> bit.

Sets internal processor register (IPR) address space
accessed by the MTPR and MFPR instructions.

Sets general register address space R0 through PC.

/N:count

Sets the range of addresses to be accessed. The console
begins at the specified address and then accesses the
number of ascending addresses specified by count, even
if the symbolic address - (minus) is used. The console
continually accesses the range of addresses until Ctrl/C
is typed. (See the REPEAT command description.)

5–10 CIO Mode Console Commands

The address specifier may be a 1- to 8-character hex address or may
specify one of the following symbolic addresses:
•

PSL — processor status longword. The address space qualifier is not
allowed when PSL is used as the symbolic address.

•

PC — program counter.

•

SP — stack pointer.

•

FP — frame pointer.

•

AP — argument pointer.

•

Rn — general register number n in decimal notation. Valid only for
R0 through R11 with the KA510 abd KA520 processor modules. Valid
for R0 through R15 with the KA550 processor module.

•

+ (plus) — location following the last location accessed by an
EXAMINE or DEPOSIT. For references to physical or virtual memory
address space, the accessed location is the last address plus the size of
the last reference. For all the other addresses, the location is the last
address plus 1.

•

- (minus) — location preceding the last location accessed by an
EXAMINE or DEPOSIT. For references to physical or virtual memory
address space, the accessed location is the last address minus the size
of the last reference. For all the other addresses, the location is the
last address minus 1.

•

* (asterisk) — last location referenced by an EXAMINE or DEPOSIT.

CIO Mode Console Commands 5–11

5.5 HALT
The HALT command suspends execution and causes the processor module
to invoke the processor console firmware.
Example
>>> HALT

! Halts the system.

The HALT command syntax is:
H[ALT]

The HALT command sends a request to the processor to halt program
execution. The HALT process stops execution, invokes the console
firmware, and saves the current processor context (PC, PSL, GPRs,
and memory management).
CAUTION
System operation may be jeopardized when you use this
command.

5.6 INITIALIZE
The INITIALIZE command initializes the system to its power-on state.
Example
>>> INIT

! Initializes the system.

The INITIALIZE command syntax is:
I[NITIALIZE]

The INITIALIZE command sets selected system registers to poweron states by performing a hard reset to the processor module and the
primary system I/O controller module.
The zone executing the INITIALIZE command is forced into a simplex
console mode. Rhe console must be in a simplex mode before executing
most diagnostic commands.

5–12 CIO Mode Console Commands

5.7 MIO
The MIO command changes the console mode from CIO to MIO.
Example
>>> MIO
MIO>

! Changes the console to MIO mode
! and issues the MIO> prompt.

The MIO command syntax is:
M[IO]

The MIO command changes the console mode from CIO to MIO to allow
use of MIO mode console commands (Chapter 6). You do not need to
halt the operating software to use the MIO mode commands, but some
commands are used for maintenance only. Maintenance commands
should be executed only from a halted system. For a remote operator
to use MIO mode, full access privileges must be set by the local operator.
For more information on terminal mode change commands, see Table 5–6.

5.8 NEW CPU
The NEW CPU command updates a new processor module with system
information from the processor module located in the partner zone.
Example
>>> NEW CPU

! The new processor module copies
! EEPROM data from the other zone.

>>> I[NITIALIZE]

! Initializes the system.

The NEW CPU command syntax is:
NEW CPU

CAUTION
The NEW CPU command is executed only by qualified
maintenance personnel.

CIO Mode Console Commands

5–13

5.9 PIO
The PIO command changes the console mode from CIO to PIO.
Example
>>> PIO

! Changes the console to PIO mode.

The PIO command syntax is:
P[IO]

The PIO command has the same function as the SET TERMINAL
PROGRAM command. In PIO mode, all keyboard characters are passed
to the operating software.
For more information on terminal mode change commands, see Table 5–6.

5.10 REPEAT
The REPEAT command continuously executes the specified console
command.
Examples
>>> REPEAT E 27

! Continuously examines location
! 27 (hex) until Ctrl/C is typed.

The REPEAT command syntax is:
R[EPEAT] command

The command may be any CIO mode command except TEST Z (KA550
only), REPEAT, CIO, PIO, MIO, HALT, SHOW, or SET. Execution
continues until the operator types Ctrl/C from the keyboard. A command
must be supplied.
CAUTION
The REPEAT command is used only during maintenance
procedures.

5–14 CIO Mode Console Commands

5.11 SET
Follow these rules whenever you issue the SET commands from
CIO mode:
1. Issue the INITIALIZE command from CIO mode to make sure the
zones are in SIMPLEX mode.
2. Be sure to issue identical SET commands to both zones. Failure to do
so may result in an EEPROM CHECKSUM message each time the
zones attempt to synchronize.
3. A SET BOOT command issued to provide single-fault protection
during boot should include the bootpath designation for both zones
and both members of the system disk shadowset. This ensures that
both zones boot using the same boot command string.
A typical boot command for a model 610 with expansion might be:
>>> SET BOOT DEFAULT /R5:70000000 DIA0, DIG1, DIB10, DIF10

When both zones have booted, the software boots to root 7 on system
disk DIA0 (zone A) or DIG0 (zone B). If the disk is inaccessible, the
shadowset partner provides backup access to the system disk through
the other zone.

CIO Mode Console Commands

5–15

5.11.1 SET BOOT
The SET BOOT command names and stores a boot command.
Examples
1.

>>> SET BOOT DISK /R5:5 DIA0
! Creates an RF-series boot command called
! DISK and stores it in EEPROM.

>>> SET BOOT ENET EPF0
! Creates an Ethernet boot command
! called ENET and stores it in EEPROM.

>>> SET BOOT DEFAULT DIA0
! Creates the default boot specifier
! and stores it in EEPROM.

The SET BOOT command syntax is:
SE[T] B[OOT] name [/qualifier] [device list] [/qualifier]

The name specifier must be a 1- to 4-character symbolic name for
the stored boot command. Use of symbolic names that are the same
as the device specifiers is not recommended. A qualifier may be included
before or after the device specifier. The syntax is the same as for the
BOOT command.
Example 1 creates a command to boot from an RF-series disk and stores
it in EEPROM. When the command BOOT DISK is given, general register
R5 passes a hex value of 5 to the VMB bootstrap program, and the boot
uses disk unit 0 on the primary system I/O controller module in zone A.
Example 2 creates a command to boot from Ethernet and stores it in
EEPROM. When the command BOOT ENET is given, the boot uses the
Ethernet port on the primary system I/O controller module in zone B.

5–16 CIO Mode Console Commands

Example 3 creates a default boot specifier and stores it in EEPROM. The
default boot specifier is used during autoboot or when no device list is
used with the BOOT command. The word DEFAULT must be spelled out.
It is not a symbolic name.
Use the following console command sequence to define a default boot
specifier:
>>> INIT
>>> SET BOOT DEFAULT name

>>> SHOW BOOT

! Initializes the system.
! Creates the default boot specifier.
! (You must use this command for
! both zones.)
! Displays all stored boot commands.
! (You must verify that the default
! is the same for both zones.)

If the BOOT command is issued without arguments, the process uses the
saved boot specification called the default.
If you issue the SET BOOT name command without a device specifier and
press Return , the stored boot location is cleared:
>>> SE[T] B[OOT] [name]
>>>

5.11.2 SET PORT
The SET PORT command sets the operating parameters for the terminal
port issuing the command.
Example
>>> SET PORT /SPEED=9600
! Sets terminal port input and output
! rate to 9600 baud.

The SET PORT command syntax is:
SE[T] [/P[ermanent]] P[ORT] /qualifier(s)

The qualifiers are listed in Table 5–5. At least one qualifier must be
supplied.
The SET PORT command affects only the terminal port connected to the
terminal issuing the command. It may be issued from the local console
terminal or the remote console terminal (with full access privileges). It
uses the same qualifiers that are used with the SET LOCAL and SET
REMOTE commands.

CIO Mode Console Commands

5–17

Table 5–5 SET PORT Command Qualifiers
Qualifier

Function

/B[reak], /NOB[reak]

/BREAK enables baud-rate cycling for the port after the
port receives two consecutive Break characters from the
terminal. /NOBREAK disables the baud-rate cycling for
the port.

/U[pper], /L[ower]

/UPPER changes the received character to uppercase
before it is interpreted by the console. (Has no effect in
PIO mode.) /LOWER inhibits changes to uppercase; all
characters are accepted and interpreted as received.

/H[ardcopy],
/NOH[ardcopy]

/HARDCOPY sets the console for hard-copy terminal
operation. /NOHARDCOPY sets the console for video
terminal operation. (These qualifiers have the same
effect as /NOSCOPE and /SCOPE.)

/SC[ope], /NOS[cope]

/SCOPE sets the console for video terminal operation.
/NOSCOPE sets the console for hard-copy terminal
operation. (These qualifiers have the same effect as
/NOHARDCOPY and /HARDCOPY.)

/SYNC_I[n],
/NOSYNC_I[n]

/SYNC_IN causes the console to recognize the Ctrl/S and
Ctrl/Q flow-control characters. /NOSYNC_IN causes the
console to ignore Ctrl/S and Ctrl/Q and pass them as
normal characters.

/SYNC_O[ut],
/NOSYNC_O[ut]

/SYNC_OUT causes the console to generate Ctrl/S and
Ctrl/Q for flow control from the processor module.
/NOSYNC_OUT causes the console to disable flow
control.

/SP[eed]=rate or
/SP[eed]:rate

Sets the baud rate for the port issuing the command.
Valid baud rates are: 300, 600, 1200, 2400, 4800, 9600,
and 19200. The default baud rate is 9600.

5–18 CIO Mode Console Commands

5.11.3 SET TERMINAL PROGRAM
The SET TERMINAL PROGRAM command sets the I/O mode for the
terminal issuing the command.
Example
>>> SET TERMINAL PROGRAM
! Sets the terminal to the program
! I/O mode.

The SET TERMINAL PROGRAM command syntax is:
SE[T] T[ERMINAL] P[ROGRAM]

The SET TERMINAL PROGRAM command is synonymous with the PIO
command. The mode change commands are listed in Table 5–6.
Table 5–6 Terminal Mode Change Commands
Command

Function

P[io] or SE[t]
T[erminal] P[rogram]

mode. To recognize and process PIO commands, the
operating software must be running. In PIO mode,
all keyboard characters are passed to the operating
software.

CI[o]

Changes the console mode from MIO to CIO. The Break
key is used to enter CIO mode from PIO mode. To
recognize and process CIO commands, the operating
software must be halted and the processor must be
running the console firmware.

M[io]

Changes the console mode from CIO to MIO. You cannot
enter MIO mode from PIO mode; first enter CIO mode.
You do not need to halt the operating software to use
the MIO mode commands. For a remote operator to use
MIO mode, full access privileges must be set by the local
operator.

The Z command syntax is:
Z n

The n specifies the slot ID number of an approved I/O or adapter module
in the backplane of the local zone (Chapter 4, Console Operations). If
you specify a slot that does not contain a module, the console returns an
error message.
The Z command invokes a system console communication mode that
allows the console operator to run interactive RBD tests on the designated
module. The console returns the RBDn> prompt. The n is the slot ID
number of the module under test. See Figure 4–6.

6–2 MIO Mode Console Commands

NOTE
The focus of this chapter is model 310, 410, 610, and 612 systems.
If you own a model 110 system, keep in mind the following:
•

An expanded system is always a model 310, 410, 610, or 612
system.

•

A dual cabinet system is always a model 310, 410, 610, or 612
system. In a model 110 system, the two zones are housed in a
single cabinet.

•

The Local Console Disable switch is present on model 310, 410,
610, and 612 systems. In a model 110 system, the consoles are
always enabled.

6.1 Entering MIO Mode
Using the example as a guide, follow the numbered steps to enter MIO
mode. For a remote operator to use MIO mode, full access privileges must
be set by the local operator.
Example
$
$

Break

>>>
>>> MIO
MIO>

MIO> CIO or
PIO

! From PIO mode, release the Local Console
! Disable switch (OFF, button out). The
! indicator is dark (unlit). Then press the
! Break key.

.
.
.
! Entering the CIO or PIO command returns
! you to CIO or PIO mode, respectively.

Comments are allowed on a command line. Comments, or characters
following an exclamation point (!), are ignored by the console when the
Return key is pressed. This feature is useful when documenting a console
session on a hard-copy terminal.

MIO Mode Console Commands 6–3

To enter and use MIO mode:
1. Your console terminal is connected to a system cabinet. While still
in PIO mode, check the summary panel on that system cabinet.
Make sure the Local Console Disable switch on the summary panel is
released (OFF, button out) and the indicator is dark (unlit).
2. Press the Break key to leave PIO mode. When the console enters CIO
mode it returns the >>> prompt.
3. Enter the MIO command and press Return . (The processor may be
running or halted.) When the console returns the MIO> prompt, enter
MIO commands.
4. To return to one of the other modes, enter one of these commands:
SET TERMINAL PROGRAM, PIO, or CIO.
Chapter 4 provides more information on use of the various console
operating modes.
Some commands controlling the terminal ports on the primary system
I/O controller module (SET PORT and SET TERMINAL PROGRAM)
are recognized in CIO and MIO modes. To recognize and process
CIO commands, the operating software must be halted and the
processor must be running the console firmware. CIO commands
are described in Chapter 5.

6–4 MIO Mode Console Commands

6.2 CIO
The CIO command changes the console mode from MIO to CIO.
Example
MIO> CIO
>>>

! Changes the console to CIO mode
! and issues the >>> console prompt.

The CIO command syntax is:
CI[O]

The CIO command changes the console mode from MIO to CIO to allow
use of CIO mode console commands (Chapter 5). Halt the operating
software to use the CIO mode commands.
For more information on terminal mode change commands, see
Table 6–10.

MIO Mode Console Commands 6–5

6.3 DIALOUT
The DIALOUT command invokes the console autonotification process.
Example
MIO> DIALOUT

! Invokes the console dialout procedure.

The DIALOUT command syntax is:
DIA[LOUT]

When the DIALOUT command is issued, the autonotification process dials
out using the stored notification phone number, retry count, and retry
delay time. (These parameters are set using the SET NOTIFICATION
command.) If the connection is successful, the notification message is
transmitted and the MIO> prompt is returned to the issuing console
terminal. If the connection is not successful, an error message is returned
to the issuing console terminal.
CAUTION
The DIALOUT command is used only during maintenance
procedures.

6–6 MIO Mode Console Commands

6.4 DISABLE REMOTE
The DISABLE REMOTE command disables all remote terminal console
privileges.
Example
MIO> DISABLE REMOTE

! Disables all remote console privileges.

The DISABLE REMOTE command syntax is:
DIS[ABLE] R[EMOTE]

The DISABLE REMOTE command has the same function as the SET
REMOTE OFF command. If a remote session is in progress, the command
does not take effect until the remote terminal ‘‘hangs up’’ and breaks the
connection. Future dial-in attempts are ignored.

MIO Mode Console Commands 6–7

6.5 ENABLE REMOTE
The ENABLE REMOTE command enables remote terminal console
privileges.
Examples
1.

MIO> ENABLE REMOTE
! Enables all remote console privileges.

MIO> ENABLE REMOTE USER
! Enables PIO mode access for the remote
! console.

The ENABLE REMOTE command syntax is:
E[NABLE] R[EMOTE] [U[SER]]

Without the USER option, the command has the same function as the
SET REMOTE FULL command, enabling all privileges including dial-in
access when the remote connection is made through a modem.
With the USER option, the command has the same function as the SET
REMOTE SECURE command, enabling access for the remote operator,
but only in PIO mode. If the remote terminal is in any other mode,
the command does not take effect until the remote operator enters PIO
mode. Then the remote operator cannot leave PIO mode until full access
privileges are set by the local operator.

6–8 MIO Mode Console Commands

6.6 HANGUP
The HANGUP command breaks the remote terminal telephone
connection.
Example
MIO> HANGUP

! Disconnects the telephone connection.

The HANGUP command syntax is:
H[ANGUP]

When the HANGUP command is issued from a remote terminal connected
through a modem, the modem breaks the connection by deasserting
the data terminal ready (DTR) signal. If a DISABLE REMOTE or SET
REMOTE OFF command has also been issued, the remote terminal
becomes inactive.

MIO Mode Console Commands 6–9

6.7 PIO
The PIO command changes the console mode from MIO to PIO.
Example
MIO> PIO

! Changes the console to PIO mode.

The PIO command syntax is:
P[IO]

6–10 MIO Mode Console Commands

6.8 RBD
The RBD command invokes the ROM-based diagnostic (RBD) monitor
on the primary system I/O controller module. In the RBD monitor, the
system drives can be configured using the diagnostic/utility protocol
(DUP) facility.
Example
>>> MIO
MIO> RBD
RBD1>

! Enters MIO mode from CIO mode.
! Invokes the RBD monitor and
! returns the RBD1> prompt.

The RBD command syntax is:
R[BD]

The RBD command is identical to the TEST/RBD command. It invokes
the RBD interactive mode, returns the RBD> prompt, and terminates all
other console functions. When the operator exits RBD mode, the primary
system I/O controller module initializes itself and returns to PIO mode
(the default).
CAUTION
The RBD command is used only by qualified maintenance
personnel. The RBD command must not be used while the
operating system is running.

6.8.1 Setting System Drive Parameters
Placing two drives with the same DSSI parameters in the same system
can prevent the use of one of the devices or can cause irretrievable loss of
data. Therefore, no two drives at a computer site should have the same
unit number or DSSI node name.
Drives may be written with the parameters shown in the following
sections or as required by the application. The parameters shown
in Sections 6.8.1.1 or 6.8.1.2 should be written during the system
installation. Sections 6.8.2 and 6.8.3 provide examples of how to read
and write parameters on a halted system.
If, at a later date, you need to install a new drive, or a drive that has
had the DSSI controller/interface module replaced, write the drive
parameters to configure the drive into the system. The VAXft System
Services Manager’s Guide provides further information on replacing or
configuring drives in a running system.

MIO Mode Console Commands 6–11

6.8.1.1 Base System

MIO Mode Console Commands

6–13

6.8.2 The SHOW_DSSI Command
NOTE
The SHOW_DSSI command does not apply to model 110 systems
because the node IDs are fixed at 0, 1, and 2.
The SHOW_DSSI command shows the parameters for all available drives
connected to the primary system I/O controller module in the zone issuing
the command.
Zone A of a base system might show the following combination of drives
in the left system cabinet:
RBD1> SHOW_DSSI
DSSI Node 5 (T7GAT0)
-MIA5
(TF70)
DSSI Node 6

(*)

DSSI Node 7 (R3DK3G)
-DIA7
(RF-series)
RBD1>

In the previous example, the zone A cabinet contains a TF70 cannister
tape drive in the DSSI ID 5 slot and an RF-series cannister disk drive in
the DSSI ID 7 slot. DSSI node 6 is occupied by the primary system I/O
controller module.
The drives return the following information:
•

DSSI node ID value (node 5 and 7) from the backplane

•

Factory-set DSSI node name (T7GAT0 and R3DK3G)

•

Unit number (MIA5 and DIA7) from the backplane

•

Device type (TF70 and RF-series)

6–14 MIO Mode Console Commands

Zone B of a base system might show the following combination of drives
in the right system cabinet:
RBD1> SHOW_DSSI
DSSI Node 5 (R3DK3D)
-DIA5
(RF-series)
DSSI Node 6

(*)

DSSI Node 7 (R3DK3E)
-DIA7
(RF-series)
RBD1>

In the above example, the zone B cabinet contains RF-series carrier disk
drives in the DSSI ID 5 and DSSI ID 7 slots. DSSI node 6 is occupied by
the primary system I/O controller module.
The drives return the following information:
•

DSSI node ID value (node 5 and 7) from the backplane

•

Factory-set DSSI node name (R3DK3D and R3DK3E)

•

Unit number (DIA5 and DIA7) from the backplane

•

Device type (RF-series)

6.8.3 DUP PARAMS Commands
Setting the force unit (FORCEUNI) bit to a 0 causes the drives to use the
stored unit numbers written by the DUP PARAMS procedure.
Setting the FORCEUNI bit to a 1 (the factory default) causes the drives
to use the hardwired unit numbers selected by the backplane.
CAUTION
The FORCEUNI bit must be the same in all drives in the system.
Digital recommends setting the FORCEUNI bit to 0. Doing so
causes the unit number to remain the same if the device is moved
to another DSSI device slot.

MIO Mode Console Commands

6–15

The following examples show how to write DSSI parameters to the drives
in both system cabinets of a base system. The same procedures can be
used with a system with expansion. Use the numbering sequences shown
in Section 6.8.1.1 for a base system or Section 6.8.1.2 for a system with
expansion.

Examples
1.

MIO> SET LANGUAGE ENGLISH
! Sets language to the ENGLISH option
! in volatile memory.

MIO> SET /PERMANENT LANGUAGE ENGLISH
! Sets language to the ENGLISH option
! both in volatile memory and in EEPROM.

The SET command syntax is:
SE[T] [/P[ermanent]] option parameter

The /P[ermanent] qualifier is optional, but the option and the parameter
for the option must be supplied.
Without the /P[ermanent] qualifier, the command stores the setting in
volatile memory. The volatile memory value is lost if power is removed
from the processor.
With the /P[ermanent] qualifier, the command stores the setting in volatile
memory and in EEPROM. The EEPROM value is saved if power is
removed from the processor and is written to volatile memory when power
is restored.
The SET command establishes the console settings for the following

A
TF70 Tape Drive Operation
The TF70 cannister tape drive or the TK70 fixed tape drive serves as a
system software load device. The cannister tape drive consists of a TK70
streaming tape drive shock-mounted inside a removable cannister with a
DSSI controller module and an interface module. The fixed tape drive (in
model 110 systems) is fixed behind the I/O bulkhead.
The TF70 drive accepts a TK tape cartridge that contains the magnetic
tape on a single-feed reel. When a tape cartridge is inserted, the drive
hooks the end of the tape and threads it onto a takeup reel inside the
drive. The tape must be completely rewound and unloaded before the
cartridge can be removed from the drive. Rewinding and unloading may
take up to 90 seconds. This appendix includes:

Table A–1 summarizes the TK70 tape drive controls. Table A–2 describes
the TK70 tape drive indicators.
The TF70 drive can read data from a tape written by a TK70 or TK50
drive, but it cannot overwrite a tape originally written by a TK50. (Also,
a TK50 drive cannot read a tape written by a TK70 or TF70.)
Before executing a tape command, the TF70 drive determines whether the
cartridge was written by a TK50 drive. If so, the TF70 drive sets its own
write protection so the tape cannot be written.

A.5 Handling and Storing Tape Cartridges
Observe the following precautions when handling and storing tape
cartridges:
•

Do not drop or bang the cartridge. If the tape leader is displaced, the
cartridge is unusable and may cause damage to the drive.

•

Keep cartridges out of direct sunlight and away from heaters and
other sources of heat.

•

Store cartridges in a dust-free environment where the temperature is
between 10°C and 38°C (50°F and 100°F) and the relative humidity is
between 20% and 80%.

•

If a tape cartridge has been exposed to extreme heat or cold, allow it
to stabilize at room temperature for the same amount of time it was
exposed (up to 24 hours).

•

Do not place cartridges near sources of electromagnetic interference
(terminals, motors, video or X-ray equipment). Data on the tape may
be erased.

•

Place a label on a cartridge only in the label slot shown in Figure A–3.

A.8 If There is a Problem
If you experience a problem with your drive, the following checks may
help you define the problem.
Correctable Failure During Operation
If the TF70 fails during operation, you may be able to reset the fault, then
rewind, unload, and remove the tape cartridge.
If all three drive indicators are blinking, press the unload button. If the
error is correctable, the tape begins to rewind and the yellow indicator
blinks. When the tape is unloaded, the green indicator turns on and the
beeper sounds. Then pull the cartridge release handle open and remove
the cartridge.
Noncorrectable Failure During Tape Motion
If the tape does not rewind when you push the unload button and all
three indicators continue to blink, the error is not correctable. The drive
must be replaced or serviced.
Failure During Cartridge Insertion
A cartridge fault occurs if a tape cartridge is damaged or if internal
portions of the drive that handle the cartridge are not working. Suspect
a cartridge fault if the green indicator blinks, but the tape does not
move (the yellow indicator does not blink). Remove the cartridge and try
another or inspect the tape leader and drive takeup leader.

B.1 Power-On Process
When the TF857 subsystem powers on, all of the indicators on the
operator control panel (OCP) light, within 15 seconds. The power-on
self-test, or POST, is initializing the subsystem. When POST completes
successfully, all OCP indicators, including the Magazine Fault and Loader
Fault indicators, turn off — except for Power On.
NOTE
If the Magazine Fault or Loader Fault indicator remains on, POST
has detected an error. See the TF857 Magazine Tape Subsystem
Owner’s Manual for information on error conditions.

B.2 Mode Select Key
The Mode Select key (Figure B–1) can lock the loader transfer assembly
into the enclosure, as well as lock the receiver closed. It has four modes:
OCP Disabled, Automatic, Manual, and Service. The OCP Disabled,
Automatic, and Manual modes are for operational use; the Service mode
is for head cleaning and servicing procedures.

B.2.1 Operating Modes
The following modes are for operational use:
•

OCP Disabled mode — When the magazine is inserted into the
receiver and the receiver is closed, the loader transfer assembly scans
the magazine. The first cartridge in the magazine automatically loads
into the drive.
Operations stop if you are copying data to tape and the storage
capacity of the last tape cartridge is exceeded or no tape cartridge is
in the next sequential slot in the magazine.
To lock the TF857 subsystem into the enclosure and lock the
receiver, set the Mode Select key to OCP Disabled mode. The OCP
pushbuttons are disabled.

•

Automatic mode — This mode is the default, or normal, mode of
the TF857 subsystem. It automatically loads and unloads cartridges
as necessary during backup procedures. Operations stop if you are
copying data to tape and the storage capacity of the last tape cartridge
is exceeded or no tape cartridge is in the next sequential slot in the
magazine.
To lock the TF857 subsystem into its normal operating position in the
enclosure, but leave the receiver unlocked, set the Mode Select key to
Automatic mode. The receiver can be opened; all OCP pushbuttons
are enabled.

Use the Slot Select button to select a cartridge; press this button
to advance the slot indicator light to the next available slot. After a
successful initialization, the TF857 subsystem automatically selects slot
0 and the Slot Select button becomes active. The Load/Unload and Eject
indicators remain on during the slot selection.

B.4.2 Loading the Cartridge
Press the Load/Unload button to load the cartridge into the drive.
This action causes the Select Slot, Load/Unload, and Eject indicators to
turn off, and the elevator to move to the selected slot, indicated by the
light. The cartridge is then removed from the magazine and placed in
the elevator. The elevator moves to the drive position and inserts the
cartridge into the drive. The indicators remain off until the tape has
loaded to the beginning of the tape (BOT). After the cartridge is loaded
into the drive, the Eject and Load/Unload indicators turn on, and the
corresponding buttons are enabled. The Slot Select indicator remains off.

B–8 TF857 Subsystem Operation

B.4.3 Unloading the Cartridge
CAUTION
Do not press the Load/Unload button until backup or other tape
operations are stopped at the terminal. Doing so can result in
operation failure and drive unavailability.
When you press the Load/Unload button, the Select Slot, Load/Unload,
and Eject indicators turn off, and the cartridge unloads from the drive
into the magazine. However, automatic operation now stops and the
Select Slot operation does not increment. The indicators turn on once the
cartridge is returned to the magazine.
The Load/Unload indicator must be on before you press the button to
load or unload a cartridge. If the Loader Fault indicator is on, showing a
malfunction, press the Load/Unload button to reset the subsystem and try
to clear the error.

B.4.4 Opening the Receiver
The Eject button opens the receiver for insertion or removal of the
magazine. It is disabled when the Mode Select key is in the OCP Disabled
position. The Eject button can also be used to unload a tape from the
drive.
NOTE
When a cartridge is not in the drive, the Slot Select, Load/Unload,
and Eject indicators are on before any operation begins. Pressing
the Eject button causes all indicators to turn off. The elevator
then returns to its home position and the receiver opens.
When a cartridge is in the drive, the Eject and Load/Unload
indicators are on before the operation begins. When you press the
Eject button, both indicators turn off and the cartridge unloads
from the drive and moves back into the magazine. The receiver
then opens to allow access to the magazine.
In both situations, once the receiver is closed again, a magazine
scan begins, and the indicators turn back on when the scan is
complete.

TF857 Subsystem Operation B–9

B.5 Magazine
The front of the magazine has numbers, 0 through 6, that indicate the
number of the slot.
NOTE
Insert and remove all cartridges at the front of the magazine.

B.5.1 Inserting a Cartridge into the Front of the Magazine
To simplify cartridge insertion, place the magazine on its back and facing
you. Each slot is numbered — to ensure you are inserting the cartridge
correctly in the front of the magazine. Usually, cartridges are inserted
into consecutive slots.
To insert a cartridge into the magazine:
1. Grasp the cartridge with the CompacTape III label facing up and the
write-protect switch facing you (Figure B–2).
2. Set the cartridge’s write-protect switch to the desired position. If

System Drive Removal and Replacement C–9

C.3 Using the Server Setup Switch
The server setup (SU) switch is provided for use on a running system and
has no effect when the system is halted.
CAUTION
The server setup switch must only be used during maintenance
procedures.
Using the server setup switch when you power on a drive inhibits the
drive from joining the DSSI cluster. This allows the console operator to
set host from DCL and write DSSI parameters to the drive under the
diagnostic/utility protocol (DUP) facility without halting the system.
DSSI parameters must be set whenever you install a tape or disk drive
with unknown parameters. Placing a drive in service without first
writing the parameters could cause irretrievable loss of data. Write
DSSI parameters if the drive you are installing or replacing is:
•

A new drive with factory-set parameters

•

An existing drive with a new DSSI controller/interface module

The diagnostics chapter of the VAXft Systems Maintenance Guide (EKVXFT1-MG) provides information on setting host from DCL. The RBD
command description in Chapter 6 of this manual provides information
and guidelines for writing DSSI parameters to the storage devices under
the DUP facility.
To set drive parameters on a running system, power on the drive as
follows:
1. Press and hold the server setup switch
2. Set the power switch to on (1)
3. Release the server setup switch
It takes 15 to 20 seconds for a disk drive to come up to speed and the
Ready light to turn on (light). Then set the drive switches as follows:
1. Place a disk drive on-line by releasing the summary panel On-Line
button to the out position
2. Write-enable a disk drive by releasing the summary panel Write
Protect button to the out position
3. The summary panel switches and indicators have no effect on a tape
drive

C–10 System Drive Removal and Replacement

When you have set host and written the DSSI parameters, place the drive
in service as follows:
1. Set the drive power switch to off (0).
2. Wait a few seconds for the drive power to bleed off. Wait 15 to 20
seconds for a disk drive to stop spinning.
3. Set the drive power switch to on (1). Wait 15 to 20 seconds for a disk
drive to come up to speed and the Ready indicator to turn on (light).
4. Set the Write Protect switch to the desired state and add the drive
into the system configuration.

Module Handling, Removal, and
Installation/Replacement Procedures
This appendix describes how to remove or install a logic module in a
system cabinet.
NOTE
The following procedures are intended for use during system
installation. Before using any of these procedures on a
system that is running, first contact the responsible customer
representative, system manager, or application manager to shut
down the zone and power off the system cabinet.
This appendix includes:
•

Module handling and ESD procedures

D–1

D–2 Module Handling, Removal, and Installation/Replacement Procedures

Observe the module handling and ESD procedures (Section D.1) whenever
you need to remove, install, or replace a logic module in a system cabinet.
CAUTION
An ESD wrist strap, ground clip, and grounded ESD workmat
must be used as described in Section D.1 whenever you handle
the logic modules.
If you must use any of these procedures on a running system, first contact
the responsible customer representative, system manager, or application
manager to shut down the zone and power off the system cabinet. The
VAXft System Services Manager’s Guide (AA-NL35A-TE) describes how to
shut down the zone and power off the system cabinet from the console.

D.1 Module Handling and ESD Procedures
Three grounding cords are stored in the lower front door of the system
cabinet. One cord is connected to a wrist strap. The other cord is
connected to a grounding clip for attaching to an antistatic ESD box.
When the wrist strap is in place, there must be no more than 10 M
through the grounding cord, wrist strap, and your wrist.
T3000-series modules are very fragile and static sensitive. Use the
grounding cords and observe the following precautions when handling
logic modules.
•

Always put on a grounded wrist strap before handling a logic module.

•

Be sure nothing touches the module or the components on the module
because leads can be damaged. Avoid contact with the wrist strap,
grounding cord, clothing, jewelry, cables, or other modules.

•

Minimize any potential for physical or ESD damage as follows:
— Remove all unnecessary materials in the service area (tools,
documents, paper, plastics, polystyrene).
— Avoid clothing that contains more than 80% nonconductive
materials (silk or synthetic fiber).
— Do not wear a jacket. Wear a short-sleeve shirt or roll up the
sleeves on a long-sleeve shirt.
— Do not wear jewelry.
— Loose clothing, such as a necktie, must be fastened in place.

Module Handling, Removal, and Installation/Replacement Procedures D–3

•

Before removing a module from an ESD box, place the box on a clean
surface. Do not allow the box to fall.
NOTE
Never place an ESD box on the floor.

•

Keep the module in the antistatic ESD box until you are ready to
install it.

•

Before removing a module from an ESD box, attach the grounding clip
to the ESD box.

•

If you are replacing a module, put the module you just removed on a
grounded ESD workmat on a clean surface in the service area. Put
the module side 2 down on the ESD workmat.

•

Save the ESD box for future use. Store a module in the ESD box until
you are ready to install it.

•

When removing or installing a module, be sure the module does not
come into contact with a cable or another module. Also, be sure
nothing else touches the module or any module components.

•

Hold a module only by the handle or by the edges with your hands
flat and perpendicular to the circuit board. Do not touch the etch
circuit or any components, leads, or connector pins. Do not bend the
module.

•

Do not slide the module across any surface because the leads are
fragile and can be damaged.

•

An ESD sensitive module may come into contact with the following
items only:
— Approved ESD workmat
— Antistatic packaging on the ESD workmat
— Tools and test equipment on the ESD workmat
— Chassis being serviced
— Hands of someone wearing an ESD wrist strap
