Chapter 1

Your System
Your system is a member of the MicroVAX 3100 family. This family
includes MicroVAX 3100 multiuser (time-sharing) systems and VAXserver
3100 systems. The MicroVAX 3100 family is an entry-level member of
DIGITAL's VAX family of computers.
MicroVAX 3100 multiuser systems are general purpose desktop VAX
computer systems. They have been designed for use in small business and
distributed processing environments. Several users (the number depending
on the software license purchased) can access a variety of applications
through easy-to-use directly connected terminals.
Your MicroVAX 3100 system is equipped with networking facilities which
allow you to create small local work groups or integrate your system (or
work group) into a larger network configuration.
VAXserver 3100 systems are desktop servers designed to provide operating
system services for dedicated applications or devices.
•

You can connect other VAX systems to your VAXserver 3100 to form a
networked work group.

•

You can connect other devices, for example, PCs or cash registers, to
form dedicated application work groups.

VAXserver 3100 systems support one user, the ownerllocal system manager.
Two models of the MicroVAX 3100 and VAXserver 3100 system are
available: Model 10 and Model 20. The label on the back of the system
unit identifies the model type of your system. Model 10 and Model 20
systems are similar, the primary difference being the physical size of the
system unit and consequently the number of internal storage options which
can be included.
Due to the similarity of the models, illustrations in this manual which
depict Model 20 systems are equally applicable to Model 10 systems.
Specific differences between Model 10 and Model 20 systems are explained
in the text.

(Digital Equipment Corporation's version of the UNIX operating
system). Operating system software may be factory installed on the
system disk or may be purchased separately from the hardware.

•

RX23 Diskette Drives-Model 10 systems can be configured with one
RX23 (1.4Mb) diskette drive while Model 20 systems can be configured
with one or two RX23 diskette drives.

•

Self-sensing power supply-The system power supply will accept power
inputs in the ranges 100/120 VAC and 200/240 VAC, at 50 or 60 Hertz,
without the need for a selection switch.

•

Communication ports-Three DEC423 asynchronous ports (with MMJ
connectors for VTxxx type terminals) and one MODEM port (RS232)
are provided as standard. A H8571-A adapter is provided to enable the
RS232 port to be used with many cable types.
The maximum baud rate for all four serial ports is preset to 19.2 Kbaud
but can be changed to 19.8 Kbaud (or 38.4 Kbaud) by repositioning
jumper wires on the system module. This conversion will be done by
your authorized DIGITAL service representative. The actual baud rate
for the serial ports is software programmable.

•

Optional DSH32-B communications module-The optional DSH32-B
communications module (included in some configurations) adds eight
asynchronous lines and one synchronous line to your system. There are
three different types. The type is determined by the electrical interface
of the synchronous port. See Table 1-1 for a list of the models.

1.2 System Configurations
The range of options available to MicroVAX 3100 and VAXserver
3100 systems provide many different system configurations.
These
configurations are divided into two main categories, packaged systems and
base systems. The configuration categories are defined as follows:
•

Packaged systems are predefined system configurations. Additional
factory integrated options ordered by the prospective Owner must be
installed by Field Service personnel.

•

Base systems are minimum system configurations which the Owner can
enhance by selecting desired options when ordering. These options are
installed in the factory.

Chapter 2

Installing Your System
Setting up your MicroVAX 3100 or VAXserver 3100 system is easy. After
helping you check that you have all your equipment (see Section 2.2), this
chapter describes:
•

Setting up your system unit

•

Attaching Ethernet terminators to prepare for networking or diagnostic
tests

•

Connecting a terminal

•

Connecting the power cord

•

Starting your system

The chapter goes on to show you everything you need to do to get your
system up and running, including:
•

What to do if you're planning to connect to a network

•

The operating system software and the options available

•

Booting your system from the system disk

•

Using VMS Factory Installed Software (FIS)

•

Connecting additional terminals

2.1 Choosing the Right Location
Use the following checklist to keep your system operating at its best:
•

Carefully read all installation instructions before you turn on the power.

•

Keep the temperature between 10° and 32°C (50° and 90°F) if your
system has a TZ30 tape drive installed. If the system does not have a
TZ30 installed, keep the temperature between 10° and 40°C (50° and
104°F).

•

Keep the relative humidity between 40% and 80% if your system has a
TZ30 tape drive installed. Tape cartridges should also be stored at this

Installing Your System

2-1

relative humidity. If the system does not have a TZ30 installed, keep
the relative humidity between 10% and 90%.
•

Keep the air well circulated to prevent excess heat and dust from
accumulating.

•

Keep your equipment away from heaters, photocopiers, direct sunlight,
and abrasive particles.

•

Before you set up your system, select a surface that is large enough to
hold the system unit. Your desk or work table is a good choice.

•

Keep the area clean. Do not place food or liquid on or near your
equipment, and do not place your system unit directly on the floor.
Dust and dirt will damage the system components.

•

Keep air vents clear on each side of the system unit for proper
ventilation.

•

Do not place the system unit on its side. Blocking the air vents can
cause the system unit to overheat.

•

Connect your system to a dedicated grounded circuit.
If you have several pieces of equipment that need to be plugged into an
electrical outlet, use a grounded power strip. Many power strips come
with an on/off switch and a surge protector.

Do not exceed the voltage requirement of the circuit.
•

To avoid damaging equipment that has been moved inside from a cold
environment, let the equipment warm to room temperature before you
tum it on. Let tape cartridges stabilize for 24 hours.

2.2 Unpacking
CAUTION: Because of the weight of the system unit, two people should lift
the equipment out of the shipping carton and place it on a work surface.

The shipping carton contains three boxes and an accessory tray. The large
box under the accessory tray contains the system unit. The other two boxes
contain the country kit and the software licenses respectively. Figure 2-:-1
shows the contents of each box. When unpacking the boxes keep the
contents of each box separate from the others. Expansion boxes are packed
in separate cartons (see Section 4.3).

NOTE: Some systems shipped within the United States include a VT320-AA
console terminal.

The contents of the shipping carton may differ from that shown in
Figure 2-1 depending on what you order. Check the contents of the shipping
carton against the shipping list.
NOTE: Depending on how you set up your system, you may not use all the
components supplied with your system. Unused parts should be stored safely
for future use.

Always repack the system unit in its original packing material when moving
or relocating your system. This precaution will protect the hard disks from
damage.

2.3 Setting Up Your System
You are ready to set up your system.

2.3.1 Identifying System Unit Ports and Connectors
Turn the system unit around so that the back of it faces you. Take a minute
to look at all the ports and connectors. Symbols (called icons) identify each
port and connector you will need to install your system.
Figure 2-2 shows the ports and connectors on the back of a MicroVAX 3100
or VAXserver 3100 Model 20 system. The arrangement of the ports and
connectors on Model 10 systems is almost identical; the only difference is
the absence of the B2 Reserved connector on the top level due to the reduced
height of the system enclosure.

2.3.3 Installing Connector Covers
Three connector covers have been provided with your system to protect·
the unused connectors on the rear panel of the system unit. After you have
identified the ports and connectors, you should install covers on the unused
connectors as determined by your system configuration.
Determine if the optional DSH32-B communications module is included in
your system. If this module is not included, install cover 1 and cover 2 as
shown in Figure 2-4 A.
NOTE: Due to the construction of the covers, cover 2 must be installed first.
NOTE: On Modell 0 systems, cover 2 is slightly different than the one shown
in Figure 2-4 A, that is, it does not contain the flat portion which conceals
the B2 Reserved connector on Model 20 systems.

If the DSH32-B communications module is included in your system, install
cover 1 as shown in Figure 2-4 B.
If you do not wish to use the external SCSI interface, install cover 3 over
the SCSI terminator as shown in Figure 2-4 A and B.

2.3.4 Attaching Ethernet Terminators
You need to connect the T-connector, two Ethernet terminators, and the
loopback connector (see Figure 2-1), to the system unit to successfully
complete the diagnostic tests later in this chapter.
NOTE: The system will not boot if an Ethernet error is detected during
power-up self-test.

The T-connector is used with two terminators to complete the ThinWire
Ethernet circuit for diagnostic purposes. Later, if you decide to connect to a
network, you exchange ThinWire cable sections for one or both terminators,
depending on your network setup.
The loopback connector, by itself, completes the standard Ethernet circuit
for diagnostic purposes.

Installing Your System 2-7

To connect the two terminators to the T-connector:
1. Push one terminator into one side of the T-connector and tum it
clockwise until it locks into place. See Figure 2-5.

2. Push the second terminator into the other side of the T-connector and
turn it clockwise until it locks into place.

2.7.3 Modifying FIS for a System in a Larger Cluster
If you intend to configure your system in a larger cluster, see the VMS

VAXcluster Manual supplied with your software documentation for detailed
information.

2.8 Installing Operating System Software
If you need to install your operating system or if you are upgrading your
operating system, you will need to have one of the following:
•

TZ30 tape drive

•

Connection to a network to load the software from another system

•

RRD40 compact disc expansion box

•

TK50Z tape drive expansion box

To set your system up to automatically start operating system software
from a particular device, see Appendix A.

2-22 MicroVAX 3100 and VAXserver 3100 Owner's Manual

Install any expansion boxes before you install your software. See Chapter 4
for additional information.
To install the VMS or ULTRIX operating system software on a MicroVAX
3100 or VAXserver 3100 system, follow the operating system software
installation instructions that are shipped with the software. During
software installation, the operating system software is transferred from
the installation media (tape or compact disc) to a hard disk in the system
or to an expansion box connected to your system.
If your MicroVAX 3100 or VAXserver 3100 is network connected, you may
be accessing the operating system from a VAXserver. For information about
accessing the VMS or ULTRIX operating system software on your server,
see your operating system documentation.

2.9 Connecting Additional Terminals
Three additional terminals can be connected to the system unit. These
terminals are connected to MMJ ports 2 and 3, and to the modem port.
A H8571-A adapter is required to convert the modem port 25-pin D-sub
connector to an MMJ connector before a terminal can be connected.
Figure 2-10 shows the ports to which these terminals are connected and
the H8571-A adapter.
CAUTION: If you use an adapter to convert the MODEM port to an MMJ
terminal port, the recommended maximum cable length is 50 ft.

3.1.1 RZ23 Hard Disk
A hard disk stores information on a nonremovable disk. In Model 10
systems, you can have up to three RZ23 hard disk drives, while in Model
20 systems, you can have up to five RZ23 hard disks in your system unit.
The RZ23 disk drive has a storage capacity of 104 Mb.
RZ23 disks are mounted internally in the system unit. Additional disks
can only be added if there is space available. To determine the number of
disks in your system, enter SHOW DEVICE at the console prompt (»»,
then press the RETURN. The resulting display lists the storage devices
mounted in your .system, the type of device, and its address on the SCSI
bus, along with other information. See Section 6.5 for further information
on the SHOW DEVICE command.
You can increase the hard disk storage capacity of your system further by
using RZ55 expansion boxes. See Chapter 4 to learn about these add-on
devices.

MicroVAX 3100 and VAXserver 3100 Owner's Manual

3.1.2 TZ30 Tape Drive
The TZ30 is a cartridge tape drive that can store up to 95Mb (or characters)
per CompacTape or CompacTape II cartridge.
The TZ30 can read or write data from a tape that was written by a TK50.
The TZ30, however, can not read or write data from a tape that has been
written by a TK70.
The TZ30 is used primarily to backup storage devices, and to load software
onto your system. For example, the VMS operating system may be loaded
from the TZ30. The tape-distributed version of VMS is loaded from a
TK50-formatted tape.
On Model 10 systems, the TZ30 tape drive (if installed) is directly accessible
from the front panel of the system unit.
On Model 20 systems, to access the TZ30 tape drive, position the system
unit so that the front of it is facing you. Open the cover by pushing it in
the direction indicated by the arrow in Figure 3-1 and then releasing it.
Use the same procedure to close the cover when you have finished using
the TZ30.
3.1.2.1 Tape Cartridges

The TZ30 uses a tape cartridge (labeled COMPACTape or COMPACTape
II) that contains the magnetic tape on a single reel. This single reel is an
important feature to understand, because it affects the use of the TZ30.
When you insert the tape cartridge into the drive and load it, the tape is
automatically threaded onto a take-up reel inside the drive. When the tape
has been fully wound onto the take-up reel, it takes approximately 100
seconds to rewind completely.
NOTE: The tape must be fully rewound before you can remove the cartridge
from the tape drive.

See Appendix F for information on the handling and storage of
COMPACTape and COMPACTape II cartridges.

3.1.2.3 Inserting and Using the Tape Cartridge
To insert a tape cartridge, perform the following steps:
1. Be sure that the cartridge lever is in the unlock position.
2.

Insert the tape cartridge.

If you insert the cartridge more than half way into the drive, you must
complete this procedure. If you wish to use another cartridge, complete
this procedure and perform the unload procedure to remove the tape
cartridge.

3-6 MicroVAX 3100 and VAXserver 3100 Owner's Manual

If the tape cartridge cannot be inserted into the TZ30, move the
cartridge lever to the lock position. Now move the cartridge lever back
to the unlock position and reinsert the cartridge. Do not push the tape
cartridge into the TZ30 while moving the cartridge lever between the
lock and unlock positions. Otherwise the TZ30 interprets this as an
insertion of the tape cartridge.
3. The green LED will light.
4. Move the cartridge lever to the lock position to lock the tape cartridge in
the drive. The green LED turns off and the yellow LED begins to blink,
indicating that the tape is loading. When the tape is loaded (ready for
use), the yellow LED stays on steadily. Whenever the yellow LED is on
steadily and the green LED remains off, the tape is ready to use.
If the write protect switch on the cartridge is in the protected position, the
orange write protect LED is on and you will be unable to write data to
the tape. If you move the write protect switch to the write enable position
during operation, the system software does not recognize the fact that the
tape is no longer write protected. You must reload the tape cartridge again
before the system software recognizes the cartridge as write enabled.
Similarly, if you move the write protect switch from the write enabled
position to the write protected position during operation, the tape is
not actually write protected until the operating system dismounts and
remounts the tape.
When the yellow LED is on steadily, you can proceed with your operation.
For example, you may boot your operating system, or possibly, back up files
onto the TZ30. See your system documentation for instructions for these
and other operations.
When the tape drive is reading, writing, or rewinding a tape cartridge, the
yellow LED blinks rapidly.
If errors occur during an operation, all three LEDs blink. The green
LED will blink if a faulty tape cartridge is inserted. If this occurs, see
Section 3.1.2.5.

3.1.2.4 Removing a Tape Cartridge from the Drive
To remove a tape cartridge, perform the following steps:
1. Press the unload button (Figure 3-4) or issue the appropriate system
software command. The yellow LED will flash as the tape rewinds.
Once the tape has rewound completely, the beeper sounds twice and
the green LED will light.

2. Move the cartridge lever to the unlock position.
3. The cartridge ejects and can be removed from the tape drive.
CAUTION: Remove tape cartridges from the drive before turning off the
drive's power. Failure to do this can result in damage to the cartridge and
tape drive.

3.1.2.5 If You Have Problems

If the TZ30 tape drive fails, read the following information. It may help
you resolve the problem.
Recoverable Errors During Tape Motion

If a drive error occurs during an operation, you may be able to clear the
fault, reset the drive, rewind, unload, and remove the tape cartridge. Try
another tape cartridge to determine if the TZ30 or the tape cartridge is at
fault.
Clearing a Recoverable Error
If all three LEDs are blinking (indicating that an error has occurred), press
the unload button. If the detected error is recoverable, the tape will begin

to rewind. While the tape is rewinding, the yellow LED blinks. When the
tape has unloaded, the drive will beep twice and the green LED will light.
You can then move the cartridge lever to the unlock position to eject the
tape cartridge.

Learning About Your System 3-9

Nonrecoverable Errors During Tape Motion
If the tape does not rewind when you push the unload button and the LEDs
continue to blink, the error is not recoverable. Call your authorized service
representative.
Errors During Cartridge Insertion
When the tape cartridge is damaged, or if internal portions of the drive that
handle the cartridge are not working, a cartridge fault occurs. If the green
LED blinks and the tape does not move (the yellow LED does not blink), a
cartridge fault has been detected. Remove the cartridge and try another.
Cartridge Incompatibility
If you cannot read or write on a tape cartridge, you may be using a
cartridge that is incompatible with the TZ30. The green LED may also
blink indicating that the TZ30 detected a cartridge error.
Testing
If you obtained diagnostics from DIGITAL or your authorized DIGITAL
representative, follow the instructions you received with your diagnostic
tape or diskette to detect any problems with the TZ30 or other device on
your system.
Inspection
If you have trouble loading a tape cartridge, it is a good idea to perform a
brief inspection of the tape cartridge leader.
Inspecting the Cartridge
Figure 3-5 shows the correct position of the tape leader inside the cartridge.
Before you attempt to use the tape cartridge, be sure the tape leader is in
the same position as the one in Figure 3-5. Lift the catch with your thumb
and open the small door to expose the leader.
CAUTION: Do not touch exposed portions of magnetic tape. If the tape
leader is not in the correct position, do not attempt to fix it. Use a new
cartridge instead.

Chapter 4

Expanding Your System
This chapter provides information about installing and using external
add-on disk storage and software load devices.
The following expansion boxes are recommended for use with MicroVAX
3100 and VAXserver 3100 systems:
•

RRD40 compact disc expansion box (600Mb)

•

RZ55 hard disk expansion box (332Mb)

•

TK50Z tape expansion box (95Mb).

Instructions for the following tasks are included in this chapter:
•

Connecting two expansion boxes of the same type to your system unit

•

Verifying the SCSI ID default (factory) switch setting on the first
expansion box

•

Setting the SCSI switches on a second expansion box.

The RZ55 and TK50Z Expansion Boxes

The RZ55 hard disk and the TK50Z tape drive provide disk and tape storage
for your system. Optionally, the TK50Z can be used as a software . load
device.
•

The RZ55 and the TK50Z are enclosed in similar expansion boxes.

•

These expansion boxes are shipped with the appropriate cables and
connectors for connecting more than one box.
The installation
procedure is the same for both types of expansion box.

•

The RZ55 and the TK50Z expansion boxes have external SCSI ID
switches. If a second RZ55 or a second TK50Z is added to the SCSI
bus, its SCSI ID must be changed to an unused ID. This is because
no two devices on an SCSI bus can have the same ID. The external
switches make it easier to change the SCSI ID.

Expanding Your System

4-1

The RRD40 Expansion Box
The RRD40 expansion box is a read-only storage device that reads data
from removable compact discs.

The RRD40 can be used for many purposes. For example, it can be used
for software installation and database storage.
•

The tabletop version of the RRD40 is contained in a smaller expansion
box than the RZ55 and the TK50Z expansion box.

•

The installation procedure for the RRD40 is the same as that for the
RZ55 expansion box and TK50Z expansion box.

•

The RRD40 expansion box has external SCSI ID switches that can be
changed if necessary, depending on your configuration.

•

A voltage selector switch permits the selection of the correct voltage for
your power requirements.

4.1 Guidelines for Connecting Expansion Boxes
Use the following guidelines when connecting expansion boxes:
•

You can connect any combination of the three expansion boxes (RZ55,
TK50Z-GA, RRD40), as long as you do not connect more than three
expansion boxes to the system at a time.

•

You must attach the 50-pin terminator that comes with your expansion
box to an unused SCSI connector on the back of an expansion box.

•

All expansion boxes should be plugged into the same grounded power
strip or electrical outlet.
CAUTION: Some expansion boxes are restricted to either 110 VAC or
220 VAC operation. Check to ensure that the voltage requirement of any
expansion box used is compatible with the supply voltage. The RRD40
expansion box has a switch for power input voltage selection.

•

Turn on all expansion boxes before you turn on your system unit.
This procedure ensures that the device in each expansion box is ready
for use, and that the system firmware includes the device in its
configuration.

4-2 MicroVAX 3100 and VAXserver 3100 Owner's Manual

4.2 Preparing Your System for an Expansion Box
If you plan to add an expansion box to your system, you must first remove
the SCSI cover and the terminator connected to the SCSI port.
1.

To remove the SCSI cover, place your fingers under the locking tab and
lift the cover to release it as shown in Figure 4-1.

MLO-0027S7

Save the terminator and cover - you must reattach them if you disconnect
all expansion boxes from the system unit.

4.3 Unpacking An Expansion Box
Each expansion box is shipped from the factory with the following
accessories:
•

One 50-pin to 50-pin cable. Use this cable to connect the expansion box
to the system unit or to other expansion boxes.

•

One power cord.

•

One 50-pin terminator. Use this to terminate the last expansion box.

•

One cable with a 68-pin connector at one end and a 50-pin connector at
the other end. This cable is not used with MicroVAX 3100 or VAXserver
3100 systems.

Make sure you have all the parts shown in Figure 4-3 before you set up
your expansion box.
In addition, the TK50Z expansion box comes with a blank tape and the
RRD40 compact disc drive expansion box comes with a empty CD caddy
and a test disc.

4.5 Connecting Two Expansion Boxes
You can add an additional expansion box at a later time and daisy-chain the
second box to the first. To daisy-chain (link two expansion boxes together
in series), perform the following steps:
1. Make sure the on/off switches on the system unit and all expansion

boxes are set to off (0).
2. Remove the 50-pin terminator on the first expansion box. Store the
terminator for future use.
3. Connect one end of the 50-pin to 50-pin connector cable to the second
expansion box.
NOTE: If you have more than one of the same type of device attached
to your system, you must change the SCSI ID on the second device to
an open ID number on the SCSI bus. See Appendix B for additional
information.

4. Connect the other end of the 50-pin to 50-pin connector cable to an
available port on the first expansion box.
5. Attach a 50-pin terminator to the unused SCSI port on the second
expansion box.
6. Connect the power cord of the second expansion box to the expansion
power receptacle and plug the other end into an electrical outlet. Each
expansion box needs its own source of power.

4.6.4 Loading A Compact Disc
When you load a disc into the compact disc drive, insert the entire disc
caddy into the disc door on the drive. Do not remove the disc from the
caddy.
To load a disc:
1.

Make sure the green power light on the front of the compact disc drive
is on.

2. Examine the disc caddy. Make sure that it is not cracked or damaged
in any way. Never load a damaged caddy into a compact disc drive.
3. Insert the disc caddy as shown in Figure 4-10. The label on the disc
should always be facing up when you insert the disc into the drive.
Make sure the notches on the left side of the disc caddy line up with
the notches on the door of the drive.
NOTE: If you have the disc positioned label side up and the notches are
on the right, then the disc is oriented improperly in the caddy. Proceed
no further with the disc loading.

4. Slide the caddy in as far as it will go and then remove it. When removed,
you will notice that the disc and its housing remain in the drive. Only
the transparent sleeve comes out.
The green activity light should come on within 5 seconds. If the drive
accepted the disc and caddy, and the activity light does not light, then
the disc may be sitting incorrectly in the caddy. Remove the disc and
then check to make sure that the label is facing up as you insert the
disc into the drive again. If the activity light still does not come on,
there may be a problem with the RRD40. Contact your local DIGITAL
Service Representative.

Chapter 5

Connecting to a Network
This chapter contains information on how to:
•

Connect and test your system with a T-connector and loopback
connector in preparation for connecting to a network

•

Create a simple daisy-chain work group

When you daisy-chain systems together to form a work group, you connect
systems together sequentially with cables and connectors.
Connecting a system to a ThinWire Ethernet network or a Standard
Ethernet network takes only a few minutes for an experienced user, slightly
longer for a new user.

5.1 A Brief Introduction to Networks
Networks are useful to people who need to work together and share
information. People like working cooperatively on projects; they need to
communicate and exchange information, share common databases, share
files and disk storage, share printers, or use a mail system. DIGITAL
networking lets them do all these.
For network installation instructions, proceed to Section 5.2. For users who
want more background, here are a few networking definitions to help you
get started:

•

Network-A network is a group of computers, connected by
communications lines, that share information and resources. A network
can span a small office, a department, a building, a country, or it can be
worldwide. DIGITAL hardware and DEC net software enable computers
to form a network.

•

Local Area Network (LAN)-A local area network is a high-speed
communications network that covers a limited geographical area, such
as an office area, a department, a building, or a campus (group of
buildings).

Connecting to a Network 5-1

•

Ethernet-Ethernet is the DIGITAL local area network.
In
1980, Digital Equipment Corporation, Xerox Corporation, and Intel
Corporation came up with a specification for the Ethernet local area
network. The specification includes information on how to connect
devices to a coaxial cable, how to configure nodes, the maximum number
of nodes, and the distance between nodes.

•

ThinWire Ethernet-All DIGITAL Ethernet products can connect to
ThinWire cable. ThinWire cable can be used in any size environment;
it is flexible, fully compatible with standard Ethernet, inexpensive,
and offers 10 megabit-per-second communication. ThinWire is ideal
for small daisy-chain standalone networks in which the users share
resources, such as printers and storage devices.

•

Standard Ethernet-Standard Ethernet coaxial cable is used to connect
wiring centers and computer facilities, floors of buildings, and
standalone ThinWire segments. It is of rugged construction, reliable,
and immune to external factors that might otherwise limit high-speed
10 megabit-per-second data communication.

•

DECnet-DECnet networking software enables many DIGITAL
computer systems to form a network. It runs on systems in both local
area networks and wide-area networks.

•

DECnet-ULTRIX-ULTRIX-32 software is DIGITAL's version of the
UNIX operating system. DECnet-ULTRIX provides an Ethernet-based
communication link between the VMS and ULTRIX operating systems.
ULTRIX-32 also uses Transmission Control ProtocollInternet Protocols
(TCPIIP) to facilitate interaction with Internet networks.

•

Work group-A work group consists of cooperating systems; Ethernet
cable connects each of the computers together. Work groups are formed
using ULTRIX-32 software or VAXNMS and DECnet software.

•

Local Area VAXcluster (LAVcJ-A Local Area VAXcluster is a group of
VAX systems that connect by means of Ethernet cable to form a cluster
(a special work group) in order to share resources, printers, and disk
storage. A LAVc consists of up to 42 nodes, any member can be the
server node. The VAXserver 3100 system is used as a server node in a
local area VAXcluster.

•

5.2 Connecting to a ThinWire Ethernet Network
If your system is a networked standalone system, that is, a system that
starts and operates independently of all other computers, you need only
make one network connection.
If you are setting up a Local Area VAXcluster (LAVc) or work group, you
may need to designate someone as the network coordinator to help create
and manage the work group, assign unique node nantes and addresses for
each system, and provide administrative assistance to users. Call your
service representative for network specific information.

If you are connecting a work group to an existing network, ask the network
coordinator for the best way to connect to the larger network. Check that
all node names and node addresses in your work group are unique and do
not already exist in the larger network.

5.2.1 Verifying the Network Select Button Position
The ThinWire/Standard Ethernet network select button is usually set to
the in position when you receive your system.
•

In - ThinWire Ethernet

•

Out - standard Ethernet

When you turn on your system, the green light to the left of the ThinWire
connector should be on, indicating that you are ready to connect to ThinWire
Ethernet.
Figure 5-1 shows the location of the network select button and the
ThinWire and standard Ethernet lights.

5.2.3 Connecting Your System to ThinWire Ethernet Cable
To connect a MicroVAX 3100 or VAXserver 3100 system to ThinWire
Ethernet cable:
1. Set your system unit on/off switch to the off (0) position.

2. Attach ThinWire cable to one side of the T-connector.
3. If your system is the first or last system in a single ThinWire segment,
leave the terminator attached to one side of the T-connector.
A segment is a length of cable made up of one or more cable sections
connected with barrel connectors or T-connectors.
4. If your system is not the first or last system and you want to connect
another system to the ThinWire cable, add another section of cable to
the T-connector as shown in Figure 5-3.
Figure 5-3:

5.3 .Creating a Daisy-Chained Work Group
A daisy-chained work group is created by serially connecting several
systems together on the same ThinWire segment. This segment can
function as a standalone network or it can be connected to a larger network.
The daisy-chain configuration lowers the cost of wiring, but there is a risk
that someone might improperly unplug a system and make the network
connections inoperative between systems on the same ThinWire segment.

5.3.1 Connecting Your System to a DECconnect Faceplate
If your office has been wired with DIGITAL DECconnect products, then
connect your system to the DECconnect faceplate in your office. A faceplate
is a wall receptacle that provides a single network connection for your
system.
DECconnect cabling components support network configurations ranging
from simple standalone ThinWire networks to multi-media LANs that
connect PCs, workstations, and other VAX systems. No matter how large or
how small your network, the most visible DECconnect component in your
office is the faceplate.
•

A faceplate may contain a single ThinWire BNC connector which
permits several systems, including VAXserver 3100 and MicroVAX 3100
systems, to be daisy-chained one to the other on the office side of the
faceplate.

•

A faceplate may contain a ThinWire Ethernet daisy-chain connector
which permits behind-the-wall daisy-chaining of multiple faceplates to
a single segment of ThinWire cable. One system can be attached to
each faceplate.
Your network coordinator will know which type of DECconnect faceplate
you have in your office.

To connect your system, attach one end of the ThinWire cable to the office
side of the DECconnect faceplate. Attach the other end of the ThinWire
cable to the ThinWire port on the back of your system unit.
Figure 5-5 shows a MicroVAX 3100 system plugged into a DEC connect
office faceplate.

5.3.2 Troubleshooting the ThinWire Segment
If you have verified your ThinWire Ethernet installation and have found
problems, use the following checklist to make sure all connections are
correct:

1. Check that all connections are secure on the ThinWire Ethernet
segment.
2. Check that there is a T-connector between the connector on the
ThinWire cable and the system unit.
3. Check that there is no ThinWire segment between the system and the
T-connector. (The T-connector must attach directly to the system.)
4.

Check that there are no branches off a ThinWire segment except
through a DEMPR (DIGITAL Ethernet Multi-port Repeater).
A DEMPR provides eight ThinWire Ethernet drops from a single
standard Ethernet connection.

Connecting to a Network 5-9

5. Check that a ThinWire segment is not looped from one port on the
DEMPR to another port on the DEMPR.
6. Check that the T-connector has not been disconnected from an operating
ThinWire Ethernet segment.
CAUTION: If you need to remove a system from an active Thin Wire
segment, simply disconnect the center of the T-connector from the system.
Figure 5-6 shows the correct way to remove a T-connector from an active
Thin Wire segment.
Figure 5-6:

Removing a System from an Active ThinWire Segment

5.4 Connecting to a Standard Ethernet Network
If you are setting up a Local VAXcluster (LAVe), you will need to designate
someone as the network coordinator to manage the network, assign unique
node names and addresses for each system, and provide administrative
assistance to users.
If you are connecting a work group to an existing network, ask the network
coordinator for the best way to connect your work group to the larger

6.6 Using the System Exerciser
The system exerciser emulates an operating system through interaction
among devices within the system. The system exerciser tests all internal
and external devices. Use the system exerciser if your system has
intermittent problems. The system exerciser takes up to 11 minutes to
complete and will not write on any media.
If you suspect problems, use the system exerciser to check the quality of
your software media. Insert a blank tape into the TZ30 or TK50Z tape
drive and the RRD40 test disc into the RRD40 compact disc drive before
running the system exerciser.
NOTE: Read your operating system documentation for shutdown procedures
before pressing the halt button.

To test your system, perform the following steps:

Handling Problems 6-13

Use the TEST 50 command to display your configuration. Check that
all devices are present in the configuration display.

2. Put the system in console mode by pressing the halt button on the rear
of the system and then pressing RETURN.
3. Enter the TEST 0 command as follows:
»> TEST 0

Appendix A

System Parameters
This appendix describes how to customize your system's startup procedures,
including how to:
•

Set the hardware to boot the operating system software from a device
other than the system disk

•

Set your system to have a particular mode of action should the system
lose power

•

Set the default boot flags for your software

•

Set a remote trigger to permit a remote system to request a local boot
of the system

A.1 Booting the System
Booting your system means an internal program attempts to load the
operating system software from a mass storage device.

A.1.1 Set the Default Boot Device
Set the default boot device to the disk drive on which the operating system
is installed. Your operating system may have been installed on the system
disk before it left the factory. If so, the MicroVAX 3100 or VAXserver 3100
system can be booted from that device at startup, using the console program
BOOT command.
If you install a higher version of the operating system on another device, or
if you have copied it from one device to another, you must set the default
boot device to the new device. The operating system software can reside in
one of the following places:
•

On a hard disk in the system unit

•

On a hard disk in an expansion box

•

On a compact disc

System Parameters

A-1

•

On a remote system that you access through the Ethernet.

Table A-I shows the names assigned to each of the possible devices. Note
that x refers to any number a through 7. The default boot device should
be set to one of the listed device names. The system disk for a MicroVAX
3100 or VAXserver 3100 system is usually DKA300.

Appendix B

SCSI IDs
This appendix contains information common to both MicroVAX 3100 and
VAXserver 3100 systems. The information is for technical users who wish
to create custom configurations.
SCSI is the acronym for Small Computer Systems Interface. SCSI is an
interface designed for connecting disks and other peripheral devices to
computer systems. SCSI is defined by an American National Standards
Institute (ANSI) standard and is used by many computer and peripheral
vendors throughout the industry.
Up to eight SCSI devices can share a SCSI bus (a cable). All data is sent
back and forth on the cable. Each SCSI device attached to the cable looks
at all the data, but a SCSI device only takes the data that has the proper
device identification (called a SCSI ID).

B.1 SCSI ID Default Settings
You are responsible for the SCSI ID settings on your equipment. Digital
Equipment Corporation sets each SCSI device to a default setting before
the equipment' leaves the factory. You may never need to change a
default setting. Default settings should only be changed when a system
is configured with more than one of a particular device.
The SCSI.ID numbers are 0 through 7; 7 is the highest ID. The number 7
is reserved for a device requiring the highest priority on the SCSI bus. The
number 6 is reserved for the controller. Six IDs (0 through 5) are available
for custom configuration.
SCSI default settings for both the MicroVAX 3100 and VAXserver 3100
systems are listed in Table B-1. The identification numbers listed give
optimal performance on most systems. However, if you have special
performance needs, you can set the identification number on each SCSI
device manually. For most applications, SCSI IDs can be set arbitrarily as
long as no two devices share the same ID.

SCSI IDs

8-1

Each device has a set of switches or jumpers that can be set for a specific ID.
The TK50Z tape drive, the RZ55 hard disk drive, and the RRD40 compact
disc drive are mounted in expansion boxes. Each of these devices have
external switches which you can set.
The integral RZ23 hard disk, the TZ30 tape drive and the RX23 diskette
drive have internal switches or jumpers. These must be reset by your
DIGITAL service representative if you need to change their default settings.

B.2 Setting the SCSI 10
Enter the TEST 50 command at the console prompt (»», then press
RETURN. Your system configuration is displayed on the screen.
Note that FFFFFF05 identifies an open ID. See Table 4-2 for a complete
list of the device status codes and their meaning. The system given in the
example contains a controller, two RZ23 hard disks, one RRD40 compact
disc drive expansion box and one TK50Z tape drive expansion box on the
external SCSI-B bus. This leaves three open IDs. Of these, ID 7 is reserved
for a device requiring the highest priority on the SCSI bus.

Follow these rules when you set SCSI IDs:
•

You can have up to seven devices on one bus.

•

Each device must have its own unique identifier.

8-2 MicroVAX 3100 and VAXserver 3100 Owner's Manual

•

Two devices may have the same identifier only if they are on different
busses.

•

Each SCSI bus must be terminated. Add a terminator to an unused
SCSI port.

NOTE: Proper operation of the SCSI bus requires that high-quality,
properly configured cables and connectors be used to connect all
devices. It is recommended that only DIGITAL-supplied cable assemblies
intended for interconnecting SCSI devices be used. This ensures that
the impedance characteristics, signal propagation velocity, inductance,
capacitance, cross-talk, grounding, conductor pairing, and shielding meet
the requirements for proper operation of the bus. In addition, it is
recommended that all units on the SCSI bus be powered from a common
AC power source. The proper operation of any SCSI bus that uses
cable assemblies not supplied by DIGITAL, or that are not configured in
accordance with DIGITAL's recommendations, is not guaranteed.

8.3 Setting SCSI Switches
SCSI IDs (addresses on SCSI bus) and the corresponding switch positions
shown in the following tables are the possible IDs and switch positions for
each expansion box.

Options
This appendix describes the hardware options available to MicroYAX 3100
and VAXserver 3100 systems.

C.1 Adding Memory
Optional memory modules can be added to MicroVAX 3100 and VAXserver
3100 systems.
NOTE: Additional memory modules must be installed by DIGITAL Field
Service personnel only.

There are three memory modules available: 4Mb, 12Mb, and 16Mb
modules. The 4Mb and 12Mb modules are physically the same. The 16Mb
module is slightly larger than the other two and it contains two additional
connectors that allow one of the other two memory modules to be connected
piggyback style. This piggyback connection allows the 4Mb and 12Mb
modules to increase the total memory in the system to 24Mb and 32Mb
(including 4Mb on the system module). The additional memory expansion
modules are shown in Table C-1:

Removable Storage Media
MicroVAX 3100 and VAXserver 3100 systems support the TZ30 tape drive,
the TK50Z-GA tape drive expansion box, the RX23 diskette drive, and the
RRD40 compact disc expansion box. All these devices use removable storage
media. This appendix contains information on the use and storage of the
media used by these devices: tape cartridges, diskettes and compact discs.

F.1 Tape Cartridges
The COMPACTape tape cartridge, Figure F -1, is a 10 by 10 cm (4 by 4
in) plastic cartridge that can be used by TZ30 or TK50 tape drives. The
TZ30 tape drive is supplied with a COMPACTape. The COMPACTape II
is the successor to the COMPACTape cartridge. The COMPACTape II is
designed with tighter tolerances than the COMPACTape to support the
higher recording densities of the TK70.
The TZ30 can use either COMPACTape or COMPACTape II tape cartridges
to record data. The TZ30 is able to read any COMPACTape cartridge
originally written by the TK5{\ If a COMPACTape II cartridge written
by a TK70 is used on a TZ30, the TZ30 automatically unloads the tape
cartridge, since the TZ30 cannot rC'ld the tape cartridge. The green LED
will then blink indicating a tape error.

F.1.1 Labeling a Tape Cartridge
Always label tape cartridges. A slot for the label is provided on the front
of the cartridge, as shown in Figure F-2. This label is visible when the
cartridge is in the drive. Labels or markings on any other part of the
cartridge can interfere with proper operation of the drive. Do not write
directly on the cartridge with pen, pencil, or other marking medium.
The labels provided with the COMPACTape or COMPACTape II tape
cartridge have spaces to check the cap'acity of the tape cartridge. If data
was written to the tape cartridge with a TK50 or a TZ30, the 95Mb block
on the label should be checked. If data was written to the tape cartridge
with a TK70, the 296Mb block on the label should be checked.
If you use both TK70 and TZ30 drives, remember that the TZ30 is unable to
read or write tapes that have originally been written by the TK70. However,
the TK70 can read tapes written by the TZ30 or the TK50.

Removable Storage Media

F-3

Figure F-2:

Labeling a Tape Cartridge

F.1.2 Writing to and Protecting Tape Cartridges
COMPACTape and COMPACTape II cartridges have a write-protect switch
to prevent accidental over-write of data. Write-protecting a tape prevents
accidental erasure of information. The system can read information on the
tape regardless of the position of the write-protect switch. However, the
system cannot write data to a write-protected tape.
F.1.2.1 Write-Protecting a Tape

When you use a tape to install software, set the write-protect switch on the
front of the cartridge to the write-protect position.
To write protect a tape, slide the write-protect switch left toward the label
until it locks in place (Figure F -3). An orange rectangle appears when the
write-protect switch locks in the write-protect position.

F-4

MicroVAX 3100 and VAXserver 3100 Owner's Manual

Figure F-3: Write-Protecting a Tape

F.1.2.2 Writing to a Tape
When you use a tape to make a backup copy or to write out data, set the
write-protect switch to enable writing to the tape.

To enable writing, slide the switch to the right, away from the label, until
the switch locks in place.

Removable Storage Media F-5·

F.1.3 Handling and Storing Tape Cartridges
Inside the cartridge, a 600-foot single reel of magnetic tape stores data. A
plastic cartridge leader is at the beginning of the tape. Take the following
precautions when handling and storing tapes:
•

Do not touch the exposed surface of the tape.

•

Avoid dropping the tape cartridge. The impact can cause damage.

•

Allow tape cartridges to reach room temperature before using them.

•

Write on the identification label before sliding it into the slot on the tape
cartridge. Do not put the label anywhere else on the tape cartridge.

•

Store tape cartridges away from dust in their plastic covers.

•

Keep tape cartridges out of direct sunlight, and away from heaters
and other heat sources. Store tape cartridges at an even temperature
between 10°C and 40°C (50°F and 104°F). Store tape cartridges where
the relative humidity is between 20% and 80%.

•

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

•

Keep tapes away from X-ray equipment.

F.2 Diskettes
Diskettes are magnetic disks that store information the same way a hard
disk does, though their storage capacity is considerably less. DIGITAL
recommends that you use high-density (HD) diskettes.
Keep your diskettes dry, out of extreme temperatures and direct sunlight,
and away from anything that contains a magnet, such as a telephone.
CAUTION: Do not place diskettes or magnetic media on or near your
terminal. The electromagnetism from your terminal may damage diskettes
by distorting or el asing the magnetic patterns.

F.2.1 Writing to and Protecting Diskettes
Write-protecting a diskette prevents accidental erasure of information. The
RX23 diskette drive (included in some MicroVAX 3100 and VAXserver 3100
system configurations) can read information on the diskette regardless of

F-6 MicroVAX 3100 and VAXserver 3100 Owner's Manual

the position of the write-protect switch. However, the system cannot write
data to a write-protected diskette.
F.2.1.1 Write-Protecting a Diskette

When you use a diskette to install application software on your system, or
to protect information on the diskette, move the write-protect switch on the
back of the diskette down until it locks in place as shown in Figure F-4.
Figure F-4:

Write-Protect Switch

Write-Protecting a Diskette

----------~

MLO-002056

F.2.1.2 Writing to a Diskette

When you use a diskette to make a backup copy of a file or to write out
data, set the write-protect switch to enable writing to the diskette.
To enable writing, slide the switch up, until the switch locks in place.

F.3 Compact Discs
The RRD40 expansion box uses compact discs with a memory capacity of
600Mb. These discs are supplied in a protective caddy.

F.3.1 How to Remove the Disc from the Caddy
To remove the disc from the caddy for cleaning or caddy repair, perform the
following steps:
1. Hold the caddy so that it is facing label side down. Locate the locking
tabs on either side of the disc housing. See Figure F -5.

Removable Storage Media

F-7

2. Press down on each of the locking tabs while slightly separating the
housing from the sleeve. Use your fingernail or a sharp, pointed
instrument.
3. When both tabs have been disengaged, pull the disc housing out to
about the midpoint of the disc.
4. Hold the disc housing on each side. Exert inward pressure on the
housing so the disc will not fall out. Remove the sleeve from the
housing. Place the sleeve aside.
5. Hold the disc with your free hand as shown in Figure F-6. Position
your thumb on the outer edge of the disc and your index finger in the
center hole of the disc. Release pressure from the housing and remove
the disc.

F.3.2 How to Insert a Compact Disc Into a Caddy
A compact disc is contained inside a protective caddy for insertion into the
compact disc drive. The caddy consists of three parts: the disc, the housing,
and the transparent sleeve as shown in Figure F -5.

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

G.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 backup 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 that 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 Procedures G-1

G.1.1 Installing Standalone BACKUP on System Disk
You can install standalone BACKUP in any available root directory on the
system disk from [SYSl] 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$UPDATE:STABACKIT SYS$SYSDEVICE: IRffiurnl

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, it displays the following message:
The kit is complete.

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

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

tape cartridge drive.
To back up the system disk, see Section G.2.1.
To restore the system disk, see Section G.2.2

G.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 products. 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.

G-6 MicroVAX 3100 and VAXserver 3100 Owner's Manual

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.

Table G-1 : Standalone BACKUP Qualifiers
Qualifier

Function

/IMAGE

Allows you 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.

G.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
Section G.1.4.

described in Section G.1.2

5. Enter the BACKUP command in one of the following formats:
$ BACKUP/IMAGE/VERIFY source_drive: target_drive:

IR~urnl

$ BACKUP/IMAGE/VERIFY source drive: target drive:- IReturn I
-$ saveset.BCK/LABEL=volume_label/REWIND lR";turnl

Backup Procedures G-7

where:
•

source_drive 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
holding the backup disk or tape cartridge.

•

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/IMAGE/VERIFY DKA300: DKA200

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 G.2.2.
$ BACKUP/lMAGE/VERIFY/BUFFER COUNT=5 DKA300: MKA500: -

IReturn I

-$ APR_19_1990.BCK/LABEL=19APRF/REWIND IReturn I

6. The procedure displays the following message:
%BACKUP-I-STARTVVERIFY, 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
procedure displays the following messages:

G-8 MicroVAX 3100 and VAXserver 3100 Owner's Manual

drive.
e. When you are ready to continue, type 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, it 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. To prevent the BACKUP command

Appendix H

Removing Unwanted VMS Files
H.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 into the SYSTEM account:
$ RUN SYS$UPDATE:VMSTAILOR IReturn I

The VMSTAILOR program asks you if you want to tailor files ON or OFF.
Type OFF to remove unwanted files.
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.

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
