1.1 HSD05 DSSI-to-SCSI Bus Adapter Description
Connecting to a single port on a BA400-based VAX 4000 system DSSI bus, the
HSD05 DSSI-to-SCSI bus adapter provides connectivity for up to seven SCSI
disks or five SCSI disks and one SCSI tape device.
A DSSI bus connects to the HSD05 (installed in a BA400-series enclosure) either
internally through the system CPU, or externally through a connector on the
connector panel to the left of the card cage; SCSI bus connection is made through
a backplane connector (J30). The HSD05 is a TMSCP/MSCP-compliant device
that performs the translations required to support devices conforming to SCSI
or SCSI–2 protocols. The HSD05 supports the following devices in VAX 4000
systems:
•

TZ86 series cartridge tape subsystem

1–4 HSD05 DSSI-to-SCSI Bus Adapter Operation

One or more HSD05 DSSI-to-SCSI bus adapters can be connected on the DSSI
bus containing RFxx/TFxx drives, host nodes, or other DSSI-compliant nodes (up
to eight nodes maximum).

1.1.1 HSD05 DSSI-to-SCSI Bus Adapter Features and Capabilities
The HSD05 DSSI-to-SCSI bus adapter provides the following features:
•

Support for OpenVMS VAX systems

•

Multihost support for up to three host DSSI nodes in a cluster environment

•

User-selectable SCSI and DSSI node IDs

•

DUP support for modifying operating parameters, such as DSSI nodename
and device allocation classes

•

Host-based striping

•

Host-based volume shadowing (with some restrictions, see Section 1.1.2.1)

The HSD05 DSSI-to-SCSI bus adapter also exhibits the following performance
metrics:
•

500+ requests/second (aggregate)

•

1.7 MB/second sustained throughput (aggregate)

Each device served by the HSD05 DSSI-to-SCSI bus adapter is independently
addressable. Attached disk and tape drives appear to the host as standard
DIGITAL storage architecture (DSA) devices. Disk allocation class is userdefinable, with all attached disks sharing the class value. Tape allocation class is
independently user-definable in the same manner.
The HSD05 DSSI-to-SCSI bus adapter identifies itself as a node on the DSSI
bus. The HSD05 DSSI-to-SCSI bus adapter identifies attached disk devices as
RF72 or RA82 disk drives, and attached tape devices as TU81 tape drives. This
identification is in device name only, and does not reflect actual device geometries.

HSD05 DSSI-to-SCSI Bus Adapter Operation 1–5

1.1.2 Overview of HSD05 Operating Requirements/Limitations
The HSD05 DSSI-to-SCSI bus adapter normally serves as a terminating end of
the SCSI bus. Its factory-default SCSI node address, or SCSI ID, is 7.
The HSD05 DSSI-to-SCSI bus adapter itself should only be removed when
the power is off to all nodes on the DSSI bus that is attached to the HSD05
DSSI-to-SCSI bus adapter.
Depending upon the complexity of the configuration, total DSSI bus length should
be limited to 60 feet, with an HSD05 DSSI-to-SCSI bus adapter attached, to
guarantee DSSI bus integrity.
The HSD05 DSSI-to-SCSI bus adapter does not support dual pathing or failover
operation for attached devices.
The HSD05 DSSI-to-SCSI bus adapter does not sequence disk drives when
spinning up. To minimize surge current to the power supply, spin up one or two
drives at a time.
1.1.2.1 OpenVMS VAX Volume Shadowing
The HSD05 DSSI-to-SCSI bus adapter supports host-based volume shadowing,
but does not support controller-based shadowing assists. No HSD05 DSSI-to-SCSI
bus adapter-based Redundant Array of Independent Disks (RAID) functionality is
supported.
The HSD05 DSSI-to-SCSI bus adapter identifies attached disk devices as RF72
or RA82 disk drives, and attached tape devices as TU81 tape drives. This does
not affect the actual accessible device storage space. However, the following
restrictions apply to creating shadow sets:
•

Due to device geometry differences, a disk drive served by the HSD05 DSSIto-SCSI bus adapter cannot be part of a shadow set with true RF72 (or any
other DSSI device) disk drives.

•

Shadow sets using HSD05 DSSI-to-SCSI bus adapter-served disk drives must
be of the same SCSI device type, for example all RZ26, or all RZ26L, or all
RZ28 disk drives.

•

Disk drives configured on an HSD05 DSSI-to-SCSI bus adapter may only be
shadowed with disk drives that are also configured on an HSD05 DSSI-toSCSI bus adapter; that is, a disk drive configured on a local SCSI adapter or
on an HSC/HSJ-family controller may not be shadowed with a disk drive that
is configured on an HSD05 DSSI-to-SCSI bus adapter.

1.2 Setting the Device Configuration on the HSD05
DSSI-to-SCSI Bus Adapter
This section explains how to set the switches on the HSD05 DSSI-to-SCSI bus
adapter module board before you install the adapter in the VAX 4000 system.
Locate the configuration switchpack, as shown in Figure 1–2.
The device configuration switchpack contains 10 switch elements, divided into
DSSI ID and SCSI ID sections as shown in Figure 1–2. Refer to Section 1.4.3.1
for detailed information on the MSCP/TMSCP unit numbers.

1.2.1 Selecting and Setting the DSSI ID
The HSD05 DSSI-to-SCSI bus adapter is connected to the standard DSSI bus 0
on the VAX 4000 host computer and is externally accessable through the DSSI
port on the connector panel to the left of the card cage.
Each device on the DSSI bus requires a unique device address in the range of 0
through 7. The DSSI ID of the HSD05 is factory set to 0; you may need to change
this ID to one that is currently not being used on your system.
Table 1–6 lists the sections of SW2 used for setting the DSSI ID and the
corresponding settings for each DSSI ID. On the switchpack, the closed position
is with the switch in the down position, and the open position is with the switch
in the up position.

2. Select an unused DSSI ID number for the HSD05 DSSI-to-SCSI bus adapter.
3. Refer to Figure 1–2 and Table 1–3 to locate the DSSI ID switches on the
device configuration switchpack.
4. Using a small blade screwdriver or similar tool, set the switches to the DSSI
ID number selected in Step 2.

1.2.2 Selecting and Setting the SCSI ID
The SCSI port plugs into the SCSI backplane connector (J30) when the HSD05
DSSI-to-SCSI bus adapter is installed in the card cage. This port must have a
unique SCSI ID.
The HSD05 DSSI-to-SCSI bus adapter is factory set to SCSI ID = 7 to give
the adapter the highest priority on the SCSI bus. The other devices in the
configuration must have SCSI ID numbers between 0 and 6. For normal
operation, you do not need to reset the SCSI ID.
Table 1–7 lists the sections of SW2 used for setting the SCSI ID and the
corresponding settings for each SCSI ID. On the switchpack, the closed position
is with the switch in the down position, and the open position is with the switch
in the up position.

2. Verify that the HSD05 DSSI-to-SCSI bus adapter indicators (shown in
Figure 1–2) are correctly lit as described in Table 1–4.
3. At the system console prompt, enter the console command SHOW DEVICE
on the OpenVMS VAX system to verify that the HSD05 DSSI node address is
online to the host system.

1.4 Setting Parameters for the HSD05 DSSI-to-SCSI Bus
Adapter
The OpenVMS diagnostic and utility protocol (DUP) utility provides a gateway to
modifying HSD05 DSSI-to-SCSI bus adapter parameters and parameters for the
devices connected to the HSD05. You can run this utility from either the system
console or from the OpenVMS system prompt.
Once a DUP connection to the HSD05 DSSI-to-SCSI bus adapter is established,
the onboard PARAMS configuration utility is used to set and show HSD05 and
device parameters. Section 1.5 contains procedures for using the HSD05 onboard
device and diagnostic utility (UTILIT) during normal operation of the subsystem.
In the following sections, user input is shown in boldface type in the examples.

Parameters
Parameter
Name

Definition

NODENAME

HSD05 node name. This value must be unique among all systems
in the VAXcluster system. The string cannot include the dollar
sign ($) or underscore (_) characters, and cannot be longer than
eight characters. The factory default for the node name is a unique
six-digit number.

SYSTEMID

Specifies the lower order 32 bits of the 48-bit system identification
number. The factory default for this identifier is the same as
specified by the NODENAME parameter.

DISK_ALCS

Determines the device allocation class for all disk devices connected
to the HSD05 DSSI-to-SCSI bus adapter. If disks are to be served
to other nodes within the VAXcluster, this parameter must be nonzero and match the ALLOCLASS SYSGEN parameter on connected
systems. The factory default for this parameter is zero.

TAPE_ALCS

Determines the device allocation class for all tape devices connected
to the HSD05 DSSI-to-SCSI bus adapter. If tapes are to be served
to other nodes within the VAXcluster, this parameter must be nonzero and match the ALLOCLASS SYSGEN parameter on connected
systems. The factory default for this parameter is zero.

INTERVAL

Controls the rate at which SCSI device scanning is done. This value
is only used if SCANNING is enabled. The factory default for this
parameter is 60 seconds.

NUMPOLL

Controls the number of SCSI devices to look for during each
INTERVAL. This parameter is currently not implemented but
may be activated in a future revision of the firmware. The factory
default for this parameter is 7, which scans for all available units at
each interval.

UNIT_OFFSET

Helps to differentiate devices when a system has two DSSI buses.
Unit offset is specified as the value to be used in the thousands
position of the MSCP unit ID, such as x for DIAx210. This offset is
automatically created by the system. The unit offset values must
be unique for each DSSI bus on the system. The factory default for
this parameter is 0.

SYNC_RATE

The rate in MHz that data is transferred during the data
transmission phase between target and host. The factory default for
this parameter is 7 MHz.

Adapter Parameters
Parameter
Name

Definition

MAX_HOSTS

Determines the maximum number of hosts with which the HSD05
DSSI-to-SCSI bus adapter can communicate. This parameter
is primarily used for disk and tape credit allotment. For best
performance, set this parameter to the maximum number of hosts
to be used. Digital supports up to three hosts (the factory default)
in a multihost HSD05 DSSI-to-SCSI bus adapter configuration.

FASTSCAN

Reduces the SCSI SELECT timeout to a much smaller value, with
the default timeout set at 250 milliseconds. This parameter is
currently not implemented. The factory default for this parameter
is 0 (disabled).

SCANNING

Enables/disables the HSD05 DSSI-to-SCSI bus adapter’s ability
to scan for newly connected devices. If scanning is disabled, the
HSD05 DSSI-to-SCSI bus adapter only does one scan for devices
at power up, and does not look for new devices every INTERVAL
seconds. The factory default for this parameter is 1 (enabled).

DISCONNECT

Enables/disables the ability to disconnect all SCSI devices connected
to the HSD05 DSSI-to-SCSI bus adapter. When only one device is
connected to the HSD05 DSSI-to-SCSI bus adapter, this parameter
can be disabled for better performance. The factory default for this
parameter is 1 (enabled).

POWERONRST

Enables/disables issuing a SCSI BUS RESET command when the
system is turned on. The factory default for this parameter is 1
(enabled).

TRYSYNC

Enables/disables synchronous negotiation when a SCSI device is
initialized. For very short cables, synchronous negotiation can be
disabled for better performance in ASYNC mode rather than SYNC
mode. The factory default for this parameter is 1 (enabled).

SPIN_DOWN

Enables/disables the ability of the HSD05 DSSI-to-SCSI bus adapter
to spin down drives or eject media when the operating system
issues a spin down command, such as the OpenVMS command
DISMOUNT/UNLOAD. The factory default for this parameter is 1
(enabled).

TAGGED_CMD

Enables/disables simple tag queuing. The factory default for this
parameter is 1 (enabled).

Definition

TRUNCATE

This parameter truncates the number of blocks to be divisible
by 126. The factory default for this parameter is 1. This default
supports faster OpenVMS volume shadowing catch-up time. A value
of 0 selects no truncation for compatibility with other third-party
units.

DEVICE_TYPE

This parameter applies to disk drives only. When disabled (set to 0),
the device type reported by the HSD05 DSSI-to-SCSI bus adapter
to the OpenVMS operating system is an RA82 disk drive. When
enabled, the HSD05 DSSI-to-SCSI bus adapter reports the RF72
device type. The device type reported to the host does not affect the
accessible disk space. The factory default for this parameter is 1
(enabled).

IMMEDIATE

When enabled, this parameter causes the IMMEDIATE bit in the
SCSI START and STOP commands to be set. Note that when
IMMEDIATE is set to 0, the OpenVMS prompt does not return
until the drive’s media is ejected or the drive has spun down. The
factory default for this parameter is 1 (enabled).

CMD_P3

Determines the type of transmission used on the DSSI bus for
single host configurations only: 0 for standard and 1 for fast mode.
This is a hidden parameter that is not displayed by the PARAMS
SHOW /ALL, SHOW /SCSI, or SHOW /SCS commands. To display
this parameter value, use the SHOW CMD_P3 command in the
PARAMS utility. The factory default for this parameter is 1 (fast
mode).

TMARKSEARCH

Enables fast tape mark searching. Because some tape drives
perform slowly while looking for tape marks during operations
on large space records, a skip tapemark is done instead. Because
the device does not report the number of records skipped between
tapemarks, the position (object) count is not correct when this
parameter is enabled. The factory default for this parameter is 0
(disabled).

SHORT_TMARK

Enables/disables writing short filemarks on Exabyte devices. When
disabled, all filemarks are written as large filemarks. The factory
default for this parameter is 1 (enabled).

WT_PROTECTED

Enables/disables write protection for each SCSI ID. When disabled
(set to 0), it allows read-write access to a SCSI ID, and when
enabled, it restricts access to read only. This parameter is in the
form of a boolean matrix, with the leftmost position representing a
SCSI ID of 7, and the rightmost position representing a SCSI ID
of 0. For example, a WT_PROTECTED setting of 00000001 allows
read-write access to SCSI IDs 1 through 7 and read only access to
SCSI ID 0. The factory default for this parameter is 00000000 (no
devices write protected).

ONLINE

Controls whether devices are online or offline to the host. This
parameter is in the form of a boolean matrix, with the leftmost
position representing SCSI ID=7, and the rightmost position
representing SCSI ID=0. For example, an ONLINE setting of
10000000 sets SCSI IDs 0 through 6 offline and SCSI ID 7 online.
The factory default for this parameter is 11111111 (all devices
online).

NAME_ALGRM

This parameter is fully described in Section 1.4.3.1.

SCSI_ID_X

Used in conjunction with the NAME_ALGRM parameter to set
alternative device names for each SCSI ID.

1.4.3.1 The NAME_ALGRM Parameter
The NAME_ALGRM parameter toggles between the HSD05 DSSI-to-SCSI bus
adapter’s standard device naming convention and an alternative convention based
upon the TMSCP/MSCP unit number. When NAME_ALGRM is set to the default
of 0, the HSD05 DSSI-to-SCSI bus adapter uses its standard naming algorithm,
which assigns a unit number based on the following parameters:
•

Unit offset (w)—A unique number (0 - 9) for each host DSSI bus. This
parameter can be used to modify bus numbering conflicts in multiple DSSI
bus configurations. It is recommended that this parameter be set to the DSSI
bus number.

•

DSSI ID (x)—The DSSI device address for the HSD05 DSSI-to-SCSI bus
adapter.

•

SCSI ID (y)—The SCSI device address for the storage device. This is set by
the bus node ID plug on the device bezel.

•

SCSI logical unit number (z)—The device address of a subdevice attached
to a SCSI device identified by SCSI ID y (usually 0).

1–20 HSD05 DSSI-to-SCSI Bus Adapter Operation

Setting NAME_ALGRM to 1 activates the alternative naming algorithm, which
assigns a unit number in conjunction with the SCSI_ID_X parameter. These two
conventions are summarized in the next table:

1.4.4 Set Device Parameters Using the PARAMS Configuration
Utility
The HSD05 DSSI-to-SCSI bus adapter operating parameters are initialized at the
factory. Depending upon the specific configuration of your system or cluster, the
following device parameters (at the minimum) may need to be set:
•

NODENAME—A unique six character DSSI node name for the HSD05.

•

DISK_ALCS—It is recommended that this parameter be set to match the
ALLOCLASS VMS SYSGEN parameter on connected systems.

•

TAPE_ALCS—It is recommended that this parameter be set to match the
ALLOCLASS VMS SYSGEN parameter on connected systems.

•

UNIT_OFFSET—It is recommended that this parameter be set to the DSSI
bus number.
CAUTION
Device unit numbers as seen by the hosts must be unique throughout the
system or cluster containing the HSD05 DSSI-to-SCSI bus adapter. If a
unit number is added that overlaps the unit number of another device on
another controller in the system or cluster, all the devices on that other
controller can disappear. In this event, the unit number conflict should
be resolved, and controller power should then be cycled off/on to make the
devices available to the host system or cluster.

Use the following procedure to set new device parameters:
1. At the PARAMS prompt, enter the parameters you wish to change; for
example:
PARAMS> SET NODENAME HSD1
PARAMS> SET DISK_ALCS 10
In this example, the NODENAME has been changed to HSD1 and the DISK_
ALCS parameter set to 10.

3. Save the changes to nonvolatile memory with the following command:
PARAMS> WRITE
4. Reboot the HSD05 DSSI-to-SCSI bus adapter to use the new parameters.
PARAMS> RESTART
5. Reboot the host systems to update the host device tables to the new settings
for the HSD05 DSSI-to-SCSI bus adapter and attached devices. Verify
that any parameter changes are shown at both the console and within the
OpenVMS operating system.
CAUTION
The HSD05 DSSI-to-SCSI bus adapter returns a limited set of device type
identification names to the host. All attached tape drives are identified
as TU81 (MUAxxx). All attached disk drives are normally identified as
RF72 (DIAxxx); this can be changed to identification as RA82 (DUAxxx)
by setting the HSD05 parameter DEVICE_TYPE to 0. These device types
as reported to the host do not affect actual accessible device storage space.
Due to device geometry differences, a disk drive served by the HSD05
DSSI-to-SCSI bus adapter cannot be part of a shadow set with true RF72,
or any other DSSI disk drives. Shadow sets using HSD05 DSSI-to-SCSI
bus adapter-served disk drives must be of the same SCSI device type; for
example, all RZ26L or all RZ28 disk drives.

HSD05 DSSI-to-SCSI Bus Adapter Operation 1–23

1.5.3.7 The QUALIFY Command
It is recommended that you run one or more qualification passes with the
QUALIFY command after a drive is formatted. The device to be qualified must
first be selected with the SELECT command.
Syntax
The following is the syntax of the QUALIFY command:
QUALIFY device_name [/write]
The symbol device_name refers to a valid MSCP device label for a direct access
device. Direct access devices, such as disk drives, are specified with the ‘‘DIA’’
prefix to the device label, for example, ‘‘DIA100.’’ The /WRITE qualifier selects a
write-read qualify operation.
The QUALIFY command can run either read-only or write-read (using the
/WRITE qualifier). The write-read qualification operation consists of writing
sequential 32-kilobyte chunks of data to the device and then reading it back.
This sequence repeats until all logical blocks on the device have been written and
read. Bad blocks are replaced and retested in a write-read qualify operation. You
should use the write-read qualifier for newly formatted drives.
Running QUALIFY in the read-only mode verifies media readability and
consistency, but does not alter any drive data.
You are prompted to confirm the qualify operation on the selected device.
Answering ‘‘N’’ or ‘‘NO’’ aborts the operation with no change to the data on
the device. Answering ‘‘Y’’ or ‘‘YES’’ to this prompt starts the qualify operation on
the device.
QUALIFY runs until it is terminated with the ABORT command or until the
HSD05 DSSI-to-SCSI bus adapter is powered off. The number of passes made is
displayed on a pass counter.

1.5.3.8 The DISKTEST Command
The DISKTEST command performs an exercise on the selected disk device. You
should run DISKTEST on all newly formatted and qualified devices. The device
to be exercised must first be selected with the SELECT command.
Syntax
The following is the syntax of the DISKTEST command:
DISKTEST device_name [/write]
The symbol device_name refers to a valid MSCP device label for a direct access
device. Disk drives are specified with the ‘‘DIA’’ prefix to the device label. The
/WRITE qualifier selects a write-read disktest operation.
The DISKTEST command can run either read-only or write-read (using the
/WRITE qualifier) tests. The write-read DISKTEST operation consists of writing
to randomly selected logical blocks and verifying the data. This sequence repeats
until all logical blocks on the device have been written and read, then the test
begins again until the ABORT command is entered to terminate the DISKTEST.
You must perform a write-read disktest to write data to the disk before you
perform the read-only disktest.
You are prompted to confirm the DISKTEST operation on the selected drive.
Answering ‘‘N’’ or ‘‘NO’’ aborts the operation with no change to the data on the
device. Answering ‘‘Y’’ or ‘‘YES’’ to this prompt starts the DISKTEST on the
device.
Running the DISKTEST operation with the /WRITE qualifier replaces media
errors when encountered. If other types of errors occur, the test is stopped and
the error condition is displayed in the Maint Status field of the display.
The DISKTEST test operation runs until it is terminated with the ABORT
command or until the HSD05 DSSI-to-SCSI bus adapter is powered off.

1.5.3.9 The TAPETEST Command
This command performs a tape exercise on the selected tape device. This test
requires enough tape to accommodate 10 megabytes of 1-kilobyte blocks. The
device to be exercised must first be selected with the SELECT command.
Syntax
The following is the syntax of the TAPETEST command:
TAPETEST device_name
The symbol device_name refers to a valid TMSCP device label for a direct access
or sequential access device. Tape drives are specified with the ‘‘MUA’’ prefix to
the device label.
The TAPETEST exercise consists of writing, rewinding, and reading each section
of tape, up to but not including a filemark. Block sizes start at 32 kilobytes and
are halved on each successive write/rewind/read pass. The test is restarted when
the block size reaches 1 kilobyte.
You are prompted to confirm the TAPETEST operation on the selected drive.

1.6 Troubleshooting
This section contains troubleshooting information for the HSD05 DSSI-to-SCSI
bus adapter. The HSD05 DSSI-to-SCSI bus adapter uses a system of onboard
LED indicator codes to indicate the source of an internal fault. You can also use
the OpenVMS Analyze/Error utility to read an HSD05 error log for information
about devices connected to the HSD05 DSSI-to-SCSI bus adapter.

1.6.1 LED Indicators
The location of the LED indicators (DS1 through DS4) is shown in Figure 1–3.
During normal operation, these indicators are behind the module cover and are
not visible.
CAUTION
The HSD05 DSSI-to-SCSI bus adapter module cover should only be
removed for service or maintenance. This cover needs to be in place
for proper air flow and cooling, and to meet international regulatory
requirements.

When the HSD05 DSSI-to-SCSI bus adapter boots, red indicator DS2 blinks for
15 seconds before it shuts off. If this indicator blinks for more than 15 seconds, it
indicates that the onboard diagnostics have found a fault.
The fault code is read out as a two-digit error code on the indicators; each digit
of the code is indicated by the number of times the indicator blinks. The first
digit of the code is separated from the second digit by a one-second pause. A
two-second pause separates the error code from its next repetition. This code is
repeated until reset by a power-off of the HSD05 DSSI-to-SCSI bus adapter.

HSD05 DSSI-to-SCSI Bus Adapter Operation 1–47

Table 1–9 lists the serviceable error codes and the associated problem. For
all other error codes, recheck the integrity of all bus terminator and cable
connections. If these actions do not resolve the problem, replace the HSD05
DSSI-to-SCSI bus adapter.
Table 1–9 HSD05 LED Indicator Codes
Code

Problem

Resolution

DSSI port problem

Ensure that DSSI termination power is supplied by either
the host bus or the HSD05 DSSI-to-SCSI bus adapter.
Check all DSSI bus connections and terminations.

SCSI port problem

Ensure that SCSI termination power is supplied by either
the host bus or the HSD05 DSSI-to-SCSI bus adapter.
Check all SCSI bus connections and terminations.

1.6.2 HSD05 Error Logs
The HSD05 DSSI-to-SCSI bus adapter logs error conditions in the OpenVMS
error log file ERRLOG.SYS. To retrieve this information, use the OpenVMS
command ANALYZE/ERROR_LOG. Refer to the applicable OpenVMS
documentation to read this error log when troubleshooting the HSD05 DSSIto-SCSI bus adapter.
The HSD05 DSSI-to-SCSI bus adapter reports the following two types of error
logs:
•

Type 1 error logs are SCSI port related.

•

Type 2 error logs are SCSI command related.

For each of the types of error logs, there are also separate formats for disk and
tape devices.

Operating the RZ-series Integrated
Storage Element Options
This chapter tells you how to operate the RZ-series integrated storage element
(ISE) options that are supported by the HSD05 DSSI-to-SCSI bus adapter.

2.1 Introduction
The following RZ-series options are supported by the HSD05 DSSI-to-SCSI bus
adapter in the BA400-based enclosures:
•

RZ26L disk drive

•

RZ28 disk drive

•

RZ73 disk drive

•

RZ74 disk drive

Refer to Table 1–1 for the option number and a description of these ISEs.
To use any mass storage device, you must properly identify the device to your
operating system and use appropriate operating system commands. Refer to your
system software documentation for details.
Note
Refer to Section 1.4.3 and Section 1.4.4 for information on displaying or
setting device parameters.

Using the dual-disk RZ, your system can have up to seven RZ-series ISEs or up
to five RZ-series ISEs and a tape drive.

Operating the RZ-series Integrated Storage Element Options 2–1

Note
Some RZ ISEs have a dual-disk capability: Two separate ISEs can share
the same mass storage cavity and front panel.

When your system has multiple ISEs, you should separate them according to
function. For example, if your system has two ISEs, you may want to use them
as follows:
•

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

•

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

2.2 RZ-Series Controls and Indicators
Each RZ-series ISE has controls and indicators on its front panel. To access them,
open the upper system door (top key position).
Note
If your system has less than the maximum number of ISEs, a blank ISE
front panel with no controls or indicators covers the empty ISE cavities.
Such panels are required to meet international regulatory standards and
airflow requirements.
If your system has a 3.5-inch RZ-series ISE with only one disk, one set of
controls has a blank bus node ID plug and its indicators do not light.

2.4 Write-Protecting an RZ-Series ISE
The following sections describe software and hardware write-protection for the
RZ-series ISEs.

2.4.1 Software Write-Protect for RZ-series ISEs
You may want to write-protect an ISE containing sensitive data you do not want
changed or accidentally erased.
For the RZ-series ISEs, you set write-protection using VMS commands.
Your system disk (the ISE containing system software) and ISEs containing work
areas for users should be write-enabled, the normal setting.
Since the RZ-series ISE does not have a Write-Protect button, the software
write-protect is the primary method for write-protecting an RZ-series ISE.
The software write-protect uses the VMS DCL MOUNT command with the
/NOWRITE qualifier, as shown below:
MOUNT/SYSTEM/NOWRITE device_name volume_label logical_name
In this command, device_name is the device name, as shown using the VMS DCL
command SHOW DEVICE DI, volume_label is the volume label for the device,
and logical_name is the logical name of the device; for example:
$ MOUNT/SYSTEM/NOWRITE $1$DIA10: OMEGA OMEGA$DISK
The above command line software write-protects device $1$DIA10.
Dismounting and then remounting the device (without using the /NOWRITE
qualifier) write-enables the device.
Use the VMS DCL command SHOW DEVICE DI to check the protection status of
the drive. A write-protected drive shows a device status of Mounted wrtlck. Refer
to your VMS documentation for more information on using the MOUNT utility.
CAUTION
When you dismount and then mount the device again, it is no longer
write-protected.

2–6 Operating the RZ-series Integrated Storage Element Options

2.4.2 Hardware Write-Protect for RZ-series ISEs
The hardware write-protect provides a more permanent write-protection than
the software write-protect. Once you hardware write-protect an RZ-series ISE, it
remains write-protected, regardless of the availability of the operating system or
if the system is powered-down. In addition, a hardware write-protect cannot be
removed by using the MOUNT or DISMOUNT commands.
You should consider hardware write-protecting an RZ-series ISE when:
•

You want to write-protect an RZ-series ISE when the VMS operating system
is not available, such as before running the MicroVAX Diagnostic Monitor
(MDM).

•

You want to ensure that an RZ-series ISE remains write-protected, since the
hardware write-protect cannot be removed by the VMS MOUNT command
and remains in effect even if the operating system is brought down.

Refer to Section 1.4.3 and Section 1.4.4 to display and set the HSD05 operating
parameters. Refer to Table 1–8 for a detailed definition of the WT_PROTECTED
parameter.

Operating the RZ-series Integrated Storage Element Options 2–7

2.5 Changing the Bus Node ID Plugs
Spare bus node ID plugs are supplied with your system. Use them to renumber
your ISEs if you
•

Reconfigure your system with an expander

•

Create a DSSI VAXcluster configuration

The ID plugs have prongs on the back that indicate the bus node number (unit
number) of the ISE.
•

To remove a plug, grasp it firmly and pull straight out (see Figure 2–2).

•

To insert a plug, align the two center prongs with the two center slots and
press the plug into the slots (see Figure 2–2).

Figure 2–2 Removing and Inserting a Bus Node ID Plug

Bus Node
ID Plug

MLO-012723

Use these rules for renumbering your storage devices.
•

For each DSSI bus, do not duplicate bus node numbers for your storage
devices/adapters. For Bus 0, you can have only one device identified as
node 0, one device as 1, and so on. For Bus 1, you can have only one device
identified as node 0, one device as 1, and so on.

2–8 Operating the RZ-series Integrated Storage Element Options

•

That rule also applies to DSSI VAXcluster configurations. All DSSI bus node
numbers for storage devices and DSSI adapters must be unique in a shared
DSSI bus.

•

The RZ-series ISEs are numbered in increasing order from right to left
beginning with zero.

•

DSSI adapters use the highest available bus nodes. The next highest
available node (usually five) is reserved for a TZ/TLZ-series tape drive.

•

If more than one DSSI bus is used and your system is using a nonzero
allocation class, assign new Mass Storage Control Program (MSCP) unit
numbers for devices on all but one of the DSSI buses. The unit numbers
for all DSSI devices connected to a system’s associated DSSI buses must be
unique.
Note
If you change the bus node ID plugs while your system is operating,
you must turn off the system and then turn it back on for the new plug
positions to take effect.

Operating the TZ86 and TZ87 Cartridge
Tape Subsystems
This chapter explains how to operate the TZ86 and TZ87 cartridge tape options
that are supported by the HSD05 DSSI-to-SCSI bus adapter.

3.1 TZ86 and TZ87 General Description
The TZ86 and TZ87 drives are streaming tape drives. The TZ86 drive can store
up to 6.0 GB of data on a CompacTape III cartridge. The TZ87 drive can store
up to 10.0 GB of data without compression and 20 GB of data with compression,
assuming a 2:1 compression ratio, on a CompacTape III cartridge.
The TZ86 and TZ87 cartridge tape subsystems are used primarily for data
backup, for data archiving, and for loading software onto computer systems. The
TZ86 and TZ87 cartridge tape subsystems use the SCSI bus.
The TZ86 tape drive writes 56 pairs of tracks—112 tracks total—on the
CompacTape III. The drive reads and writes data in a two-track parallel,
serpentine fashion, traveling the entire length of tape on two tracks (at about 100
inches per second). The drive then steps the head and reverses tape direction and
continues to read/write on the next two tracks.
The TZ87 tape drive writes 64 pairs of tracks—128 tracks total—on the
CompacTape III. The drive reads and writes data in a two-track parallel,
serpentine fashion, traveling the entire length of tape on two tracks (at about 110
inches per second). The drive then steps the head and reverses tape direction and
continues to read/write on the next two tracks.

Description

Bus node ID plug

Identifies the bus node ID number (unit number) of the drive
to the system.

Beeper

A momentary beeper sounds when you can operate the
cartridge insert/release handle. When you hear the beep,
the green Operate Handle light is on.

Unload button

The unload button rewinds the tape and unloads the tape from
the drive back into the cartridge. The tape must be completely
rewound and unloaded into the cartridge before you remove
the cartridge from the drive. Depending on tape position, an
unload operation may take from 10 seconds to 4 minutes.
If the drive is in error state (all four top front panel lights
flashing), pushing the unload button causes the drive to reset
and unload the tape if possible.

Cartridge insert/release
handle

Operate the cartridge insert/release handle to load a cartridge
or to eject a cartridge only when the Operate Handle indicator
is on, and after the momentary beep sounds. The handle pulls
to the left to the open position and pushes to the right to
the closed position. See Section 3.7 and Section 3.8 for the
operating procedures.

Density select switch
(TZ87 only)

Pressing the density select switch once enters the density
select mode. Press the density select switch again to toggle
through the different density options. Stop when you reach the
selected density. The selected density indicator blinks and the
tape’s actual density indicator remains steady.

3.3 Running the Power-on Self-test
When the TZ86/TZ87 subsystem is powered up, the drive performs the power-on
self-test (POST). The sequence of events is listed in Table 3–4.
Table 3–4 Power-on Self-test Events
Stage

What Happens

The indicators on the TZ86 and TZ87 top front panel turn on sequentially, from
left to right and then they all stay on for a few seconds.

All indicators on the TZ87 bottom front panel turn on at the same time for
about three seconds and then turn off.

The green Operate Handle, the orange/yellow Write Protected 1 , and the yellow
Use Cleaning Tape indicators turn off.

The yellow Tape in Use indicator blinks while the tape drive initializes.

After initialization, with no cartridge loaded, the green Operate Handle
indicator turns on and the beeper sounds.

1 The Write Protected indicator is orange on the TZ86 tape drive and yellow on the TZ87 tape drive.

POST completes in about 13 seconds and the subsystem responds normally to all
commands. However, it might take longer for the media to become ready. After a
bus reset, the tape drive responds within a bus selection timeout period.

3.5 Description of the CompacTape III Cartridge
The tape cartridge, shown in Figure 3–2, is a 4 1/8-inch, gray, plastic cartridge
containing 1200 feet of 1/2-inch magnetic metal particle tape.
The CompacTape III is supplied with a:
•

Set of slide-in labels for cartridges

•

Cartridge handling information sheet

3.5.1 Cartridge Write-Protect Switch
The CompacTape III cartridge has a write-protect switch to prevent accidental
erasure of data. Before loading the tape cartridge into the drive, position the
write-protect switch on the front of the cartridge (Figure 3–2). The switch can
move to the:
•

Left, so the cartridge is write-protected

•

Right, so the cartridge is write-enabled

When the switch is moved to the left and the small orange rectangle is visible,
data cannot be written to the tape. Beneath the orange rectangle is an arrow over
two lines on the write-protect switch. The arrow over the two lines symbolizes
that data cannot be written to the tape.
On the right side of the write-protect switch is another symbol, an arrow over one
line. This symbol indicates that if the write-protect switch is moved to the right,
data can be written to the tape.

3.6 TZ86/TZ87 Density Selection
The following sections describe the TZ86 and TZ87 drive’s density select features.
CAUTION
If you reuse a prerecorded tape and write from beginning of tape (BOT),
all prerecorded data is lost. This includes density changes, since they only
occur when writing from BOT.

3.6.1 TZ87 Density Selection
To select density with the TZ87:
1. Insert the tape into the drive. The yellow Tape in Use indicator blinks while
the tape loads and calibrates.
2. After calibration completes, the yellow Tape in Use indicator remains lit.
3. Press the Density Select switch once to enter the density select mode. The
Density Override indicator and the indicator of the tape’s actual density
lights.
4. Press the Density Select switch again to toggle through the different density
options. Stop when you reach the selected density. The selected density
indicator blinks and the tape’s actual density indicator remains steady.
5. After the tape is written to in the selected format, the selected density
indicator lights steadily, and the previous density indicator shuts off.
If you have installed a tape with a prerecorded TK85 density and you use the
density selection button to select TZ87 density, the following occur:
•

The TK85 indicator remains lit, indicating that the density selection of the
current tape has not changed yet.

•

The TZ87 indicator blinks, indicating that a density change is pending.

•

The density override indicator is lit, indicating that a density selection has
been made from the front panel.

When a write from BOT occurs, the following occur:
•

The TK85 indicator goes off.

•

The TZ87 indicator becomes steady.

•

The density override indicator remains lit.

3–12 Operating the TZ86 and TZ87 Cartridge Tape Subsystems

Density selection occurs according to the following rules:
READ WRITE APPEND
The density selected reflects the density of the tape already in the drive.
WRITE from BOT
The density selected may occur via the use of the front panel Density Select
button. Using the Density Select button always overrides the existing density of
the tape.
If the Density Select button is not used, the density selected is the native default,
TZ87 mode (compression enabled).
Caution
Regardless of the operating conditions, a write from BOT destroys existing
data on the tape.

Note
You can use the drive’s control panel at various times, not just after
loading a tape. Density selection is inactive until a write command is
issued at Beginning of Tape (BOT). The controller remembers the density
selection state until you do one of the following:
•

Change the density selection.

•

Unload the tape.

Operating the TZ86 and TZ87 Cartridge Tape Subsystems 3–13

Table 3–10 lists the results of different density selection actions.
Table 3–10 Results of Density Selection
If. . .

Then . . .

You did not use the
density select button

The indicators show the actual density when the tape is
reading and writing. The drive density indicator lights steadily
and the density override indicator is off.

You used the density
select button, and if the
actual tape density is
the same as the density
you selected

The indicator for both the actual density and density override
indicators are lit. For example, if the actual tape density is
TZ87 and the selected tape density is TZ87, then the indicator
next to TZ87 lights.

You used the density
select button, and if
the actual tape density
differs from the density
selected:

1. The density override indicator lights steadily.
2. The indicator next to the actual density lights steadily.
3. The indicator next to the selected density blinks.
For example if the actual tape density is TZ87 and the selected
density is TK86, the TZ87 indicator lights steadily, the TK86
indicator blinks, and the density override indicator remains
steady. After writing from BOT begins, the TZ87 indicator
turns off, the TK86 indicator lights steadily and the density
override indicator lights steadily.

3.6.2 TZ86 Density Selection
In HSD05 applications, the TZ86 tape drive defaults to using TK86 format (high
density) for all writes from Beginning of Tape (BOT). When you append data to a
tape cartridge written in TK85 format, the current media density is used.

3–14 Operating the TZ86 and TZ87 Cartridge Tape Subsystems

3.7 Loading a CompacTape III Cartridge
The directions for loading a cartridge into the drive are printed on the front of
the drive.
The following are more detailed steps for loading a cartridge (Figure 3–3):
1. When the green Operate Handle light is on steadily, pull the cartridge insert
/release handle open.
2. Insert the cartridge and push it into the drive.
3. Push the handle closed.
The green Operate Handle light turns off and the yellow Tape in Use light blinks
to show the tape is loading. When the tape is at the beginning-of-tape (BOT)
marker, the yellow Tape in Use light turns on steadily. The tape is now ready for
use.
Figure 3–3 shows how to load a CompacTape III cartridge into the drive.

3.9 Preserving CompacTape III Cartridges
For longer life of recorded or unrecorded cartridges, store cartridges in a clean
environment with the following conditions:
•

Do not drop or bang the cartridge. Doing so can displace the tape leader,
making the cartridge unusable and possibly damaging the drive.

•

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

•

Store tape cartridges in temperatures between 10°C and 40°C (50°F to 104°F).
For longer cartridge life, always store the cartridge in its plastic container
and in room environment conditions of 22°C ± 4°C (72°F ± 7°F).

•

If the tape cartridge has been exposed to heat or cold extremes, stabilize
the cartridge at room temperature for the same amount of time it was
exposed—up to 24 hours.

•

Do not place cartridges near electromagnetic interference sources, such
as terminals, motors, video, or X-ray equipment. Data on the tape can be
altered.

•

Store tape cartridges in a dust-free environment where the relative humidity
is between 20% and 80%. For longer cartridge life, store the cartridge at 40%
± 20% relative humidity.

•

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

•

Do not adhere labels to the cartridge anywhere except in the slide-in slot.

3.10 Using the CleaningTape III Cartridge
The CleaningTape III is a 4-  -inch square, light yellow, plastic cartridge
containing 1200 feet of  -inch cleaning tape. See Table 3–12 for information on
using the CleaningTape III.
Your CleaningTape III is supplied with a:
•

Slide-in label that has 20 boxes, each for marking a check after cartridge use.

•

Cartridge handling information sheet

You can use the CleaningTape III cartridge 20 times before it expires. The word
expire does not pertain to an expiration date. Expire means that there is no
unused cleaning area left on the tape.
To record the number of uses, mark a check in a box on the cartridge label after
each cleaning. After the final use, discard the cleaning tape cartridge.

3–22 Operating the TZ86 and TZ87 Cartridge Tape Subsystems

3.11 Standard OpenVMS Tape Commands
There are certain guidelines you should follow to use the TZ86 and TZ87
subsystem effectively with your host application. To maximize the subsystem’s
efficiency, you must use certain qualifiers with the MOUNT and BACKUP
commands.
Note
Not all OpenVMS tape qualifiers are functional with tape devices
connected to the HSD05.

For efficient operation of the TZ86 and TZ87 subsystems:
•

Choose a large block size when mounting a tape; 65534 is recommended.

•

Do not use the COPY command to save more than 9999 files onto the tape.
Notes
Using the COPY command to move multiple files may not achieve
optimum performance. Check with your system manager or your
OpenVMS documentation for more information.
The HSD05 DSSI-to-SCSI bus adapter always operates cache-capable
tape devices in cached mode, regardless of the setting of the MOUNT
/CACHE=TAPE command.

The TZ86 and TZ87 cartridge tape subsystems use the standard magnetic tape
commands that can be invoked under the OpenVMS operating system, version
5.4-2 or later. The OpenVMS commands used to operate the TZ86 and TZ87 are:
•

ALLOCATE

•

INITIALIZE

•

MOUNT

•

BACKUP

•

COPY

•

DISMOUNT

•

DEALLOCATE

Operating the TZ86 and TZ87 Cartridge Tape Subsystems 3–23

3.11.1 Using the ALLOCATE Command
The ALLOCATE command provides exclusive access to a device and optionally
establishes a logical name for that device. Once you have allocated a device, other
users cannot access that device until you explicitly DEALLOCATE it, or until you
log out. Use the following format to allocate the TZ86 or TZ87 subsystem:
$ ALLOCATE device_name: [logical name]
For example, to allocate the TZ86 or TZ87 subsystem for your use and assign it
the logical name TAPE1, do the following:
$ ALLOCATE MUA0: TAPE1

3.11.2 Using the INITIALIZE Command
CAUTION
When a tape is initialized, any data already on the tape will be destroyed.
Use the INITIALIZE command to specify the device name, and write a volume
name to the magnetic tape volume loaded into the TZ86 or TZ87 tape drive. The
tape must be write-enabled for the initializing operation.
For the TZ86 and TZ87, use the following format:
$ INITIALIZE device_name: [volume label]

As an example, to initialize the device MUA0 and assign the volume name
GMB001, type the following for the TZ86 and TZ87:
$ INITIALIZE MUA0: GMB001
For the initialization to succeed, the cartridge must not have been mounted (with
the MOUNT command).
For detailed information regarding volume names and magnetic tape operations,
see the Guide to VAX/VMS Disk and Magnetic Tape Operations (AA-M539A-TE).

3–24 Operating the TZ86 and TZ87 Cartridge Tape Subsystems

3.11.3 Using the MOUNT Command
The MOUNT command lets you make a magnetic tape volume available for
processing. It loads the tape with the protection set according to the write-protect
switch on the cartridge. It can determine the maximum block size on the TZ87.
Use the following format to mount a tape on the TZ86 and TZ87 subsystem for
use with the BACKUP utility:
$ MOUNT/FOREIGN/BLOCKSIZE=65534 device_name: [volume label] [logical name]

As an example, to make the device MUA0 available for processing on the TZ86 or
TZ87 and assign it the logical name TAPE1, type the following:
$ MOUNT/FOREIGN/BLOCKSIZE=65534 MUA0: GMB001 TAPE1

The screen displays a message:
%MOUNT-I-MOUNTED, GMB001 mounted on MUA0:
You must use the /FOREIGN qualifier when you are performing BACKUP
commands. Do not use it when you are performing COPY commands.

3.11.4 Using the BACKUP Command
The BACKUP command provides protection against file volume corruption by
creating backup copies.
Use the following format to back up a file on the TZ86 and TZ87:
$ BACKUP/BLOCK=65534/ignore=(label) source:*.* tape:file.name

You can also back up lists of files and entire volumes.
See your system manuals before deciding on qualifiers for use with the BACKUP
command. For detailed information about BACKUP and other OpenVMS tape
commands, see the VAX/VMS Backup Utility Reference Manual (AA-Z407B-TE).

Operating the TZ86 and TZ87 Cartridge Tape Subsystems 3–25

3.11.5 Using the COPY Command
Use the COPY command, with the TZ86 and TZ87 subsystem, to copy files from
tape.
In the following example, the MOUNT command requests that the volume labeled
GMB001 be mounted on the drive at MUA0 and assigns the logical name TAPE1.
The COPY command uses the logical name TAPE1 for the input file specification.
All files on MUA0 are copied to the current default disk and directory. The files
keep their original file names and file types.
Use the following format on the TZ86 and TZ87:
$ MOUNT/BLOCKSIZE=65534 MUA0: GMB001 TAPE1:
$ COPY TAPE1:*.* *.*

Notes
Using the COPY command to move multiple files may not achieve
optimum performance. Check with your system manager or your
OpenVMS documentation for more information.
The HSD05 DSSI-to-SCSI bus adapter always operates cache-capable
tape devices in cached mode, regardless of the setting of the MOUNT
/CACHE=TAPE command.

3.11.6 Using the DISMOUNT Command
The DISMOUNT command cancels the previous MOUNT command, makes the
unit unavailable for processing, and unloads the tape.
Use the following format for the TZ86 and TZ87:
$ DISMOUNT logical_name or device_name:

3.11.7 Using the DEALLOCATE Command
The DEALLOCATE command cancels the previous ALLOCATE command and
makes the unit available for other users. The following is an example of the
command:
$ DEALLOCATE MUA0: or TAPE1

3–26 Operating the TZ86 and TZ87 Cartridge Tape Subsystems

3.12 Solving Problems
The following sections describe what to do if you have drive or tape problems.

3.12.1 Common TZ86/TZ87 Errors
You can avoid some errors by following these guidelines:
•

Use the correct cartridge type. See Section 3.5.3.

•

Care for your cartridges according to the guidelines in Section 3.9.

•

Make sure the cartridge leader and the drive leader are in their correct
positions. See Section 3.12.2 and Section 3.12.3.

•

Unload the cartridge before powering down the system.

If an error does occur during subsystem operation, you may be able to correct the
error yourself. Factors influencing errors include:
•

Defective media

•

Dirty drive head

•

Operator or user errors

•

Incorrect backup commands

Operating the RRD43 CD–ROM and
TLZ07 DAT Tape Drive
This chapter explains how to operate the RRD43 CD–ROM and the TLZ07 DAT
tape drive option that is supported by the HSD05 DSSI-to-SCSI bus adapter.

4.1 RRD43 CD–ROM and TLZ07 General Description
The RRD43 CD–ROM and the TLZ07 DAT tape drive are available as a dual
device ISE or as single device ISEs. The dual device RRD43/TLZ07 can be
installed only in the removable-media (right-most) option slot in the VAX 4000
system. Figure 4–1 shows the dual device RRD43/TLZ07 front panel and bezel.
The RRD43 compact disc drive and the TLZ07 digital audio tape (DAT) cassette
tape drive can also be installed separately. An RRD43-JA/JF disc drive installed
separately utilizes different mounting brackets than the dual device ISE which
allows it to be installed in any storage option slot. A TLZ07-JA/JF tape drive
installed separately utilizes the same mounting brackets as the dual device
ISE and can only be installed in the removable-media (right-most) option slot.
The operating procedures are the same, whether installed as a dual device or
separately.
The RRD43 compact disc drive is a read-only device that can read information
from industry standard 600 MB compact discs. The compact disc is inserted
directly into the drive. The single ISE RRD43 compact disc drive can be installed
in any storage option slot.
Note
If the single ISE RRD43 is installed in the removable-media (right-most)
option slot in the VAX 4000 system, a small filler panel (PN 70-27414-01)
is used to fill the remaining space.

4.4.2 Inserting a Compact Disc into the RRD43 Disc Drive
To insert a disc in the RRD43, see Figure 4–3 and follow these steps.
1. Press the eject button inward to release the disc tray.
2. The tray ejects part way out; pull the tray out manually to its full extension.
3. Pick up the disc by the edges, taking care not to touch the bottom (unlabelled)
part of the disc with your hand or fingers (hold by the side edge and push into
place in the disc tray). Insert the disc into the tray with the disc label facing
to the left.
4. Push the disc tray back into the RRD43 until it is completely inserted and
latched.
The busy LED stays on for a few seconds. When the busy LED goes off, the
RRD43 can receive commands and you can read data from the compact disc.
If the disc is upside-down, not properly inserted in the tray, or if other conditions
prevent the RRD43 from reading the disc, the busy LED blinks, then stays on
steadily.
Note
To avoid false errors, use the MOUNT/NOWRITE command when
mounting the CD–ROMs (see Section 2.4).
Failure to use the /NOWRITE qualifier when mounting the CD–ROMs
results in many false error messages.

To execute the power-on self-test on the TLZ07 cassette tape drive, perform the
following:
1. Turn ON the VAX 4000 system power source.
2. Observe that, with no cassette in the drive, the Cassette and Write-Protect
indicators light for approximately 1 to 5 seconds and then extinguish.
With a cassette in the drive, the Cassette indicator continues flashing
(approximately 20 seconds) until the cassette is loaded.
3. After successful completion of the power-on self-test, the Cassette and
Write-Protect indicators turn off.
NOTE
If a tape is loaded, the Cassette indicator stays on and the Write-Protect
indicator displays the write-protect status of the cassette.

4. If the Write-Protect indicator flashes amber and the drive indicator flashes
green continuously for more than 30 seconds, then the power-on self-test
failed. Attempt to clear the failure by re-executing the power-on self-test.
(Power off and power on the drive.)

NOTES
1. The TLZ07 is compatible with TLZ04 (60 m) cassette tapes in the
noncompression mode only.
2. The TLZ07 is compatible with the TLZ06 using 60 m and 90 m tapes
only.
3. The compression measurements are typical for a 2-to-1 data
compression ratio, but the actual ratio is dependent on the data.

The cassette tape includes a write-protect tab (Figure 4–7), which contrasts
in color to the cassette tape body. Use a pen (NOT A PENCIL) to set the
write-protect tab.
•

Slide the tab to the left to write-protect the tape.

Observe the following guidelines when setting the write-protect tab.
•

If you are using the tape to read or are copying from the tape, set the writeprotect tab to write-protected. This disables writing to tape and ensures that
data will not be accidentally overwritten.

•

If you are writing data, set the write-protect tab to write-enabled.

•

The write-protect tab position is shown on the front panel Write-Protect
indicator.

4.5.4 Loading a Cassette Tape into the TLZ07 Drive
Insert the TLZ07 cassette tape into the cassette slot on the TLZ07 front panel
with the cassette’s write-protect tab at the top, facing you.
The green cassette LED flashes at 1 Hz and then goes to a steady green when the
load sequence has completed.
If the cassette tape that is being loaded has the write-protect tab in the writeprotect position, the amber write-protect LED lights. If the cassette tape that is
being loaded has the write-protect tab in the write-enable position, the amber
write-protect LED stays off.

4.5.5 Unloading a Cassette Tape from the TLZ07 Drive
Press the unload button on the TLZ07 front panel to unload the TLZ07 cassette
tape. The cassette tape unloads and is ejected from the cassette slot on the
TLZ07 front panel.
The green cassette LED flashes at 1 Hz while the tape is rewinding and then goes
off when the unload sequence has completed.
If the cassette tape that is being unloaded has the write-protect tab in the writeprotect position, the amber write-protect LED goes off when the unload sequence
has completed. If the cassette tape that is being unloaded has the write-protect
tab in the write-enable position, the amber write-protect LED stays off during the
entire unload sequence.

4.5.6 Proper Handling of Cassette Tapes
To ensure optimal performance from the TLZ07 cassette tapes, observe the
following guidelines when handling them.
•

Avoid placing the cassette tapes near sources of electromagnetic interference,
such as terminals, video, or X-ray equipment. Emissions from such equipment
can erase data on the tape.

•

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

•

Store cassette tapes (and cleaning cassette) where the room temperature is
between 5°C and 32°C (40°F and 90°F).

•

Store cassette tapes in a dust-free environment where the relative humidity
is 20% to 60%.
WARNING
Always place the tape label in the recessed area on the cassette. Never
place one label on top of another label.

4–18 Operating the RRD43 CD–ROM and TLZ07 DAT Tape Drive

4.5.7 Cleaning the TLZ07 Tape Drive Heads
This section explains how to clean the TLZ07 tape drive heads. The heads are
the components that physically read and write data to and from the media (in
this case, a cassette tape).
Digital Equipment Corporation recommends that you perform the head
cleaning procedure about every 2 weeks, or after every 50 hours of drive
usage.
Under normal conditions, it is not necessary to exceed this cleaning
schedule. If a particular data cassette causes problems, try changing to
another data cassette.
CAUTION
Never attempt to clean the heads in a manner other than described in
this procedure. Doing so voids the product warranty.

To clean the heads, use the head cleaning cassette as follows:
1. Ensure that the drive is powered on.
2. Insert the head cleaning cassette (Part No. TLZ04-HA) into the drive.
3. With the head cleaning cassette inserted, the drive automatically
executes head cleaning. The drive ejects the head cleaning cassette after
approximately 30 seconds.
4. Locate the card enclosed with the head cleaning cassette. Place a check mark
on the card every time you use the head cleaning cassette.
Under normal conditions, the head cleaning cassette is used for about
25 cleanings. Additional cassettes are available from your Digital sales
representative or DECdirect.
If the head cleaning cassette has been overused, both the Cassette and the
Write-Protect LEDs flash. Press the eject button to remove the cleaning
cassette. No cleaning action will have occurred.

Bus node ID plug set to
incorrect address.

Check bus node ID plug.

Faulty or improper cable
connection.

Remove the drive from the
VAX 4000 and check all cable
connections to the drive and
front panel. Reseat the drive
and apply power again. If the
unit is still not available to the
system, call Digital services.

The VAX 4000 system has system-based diagnostics that can be used to test the
TLZ07 tape drive. The HSD05 also has onboard utilities that can be used to test
the TLZ07 tape drive (see Section 1.5.4.3).
System-based diagnostics are usually referred to as console-based diagnostics,
self-tests, or system exercisers. Refer to your system documentation for
information about these diagnostics.

4.6 Standard OpenVMS TLZ07 Tape Commands
There are certain guidelines you should follow to use the TLZ07 subsystem
effectively with your host application. To maximize the subsystem’s efficiency, you
must use certain qualifiers with the MOUNT and BACKUP commands.
Note
Not all OpenVMS tape qualifiers are functional with tape devices
connected to the HSD05.

For efficient operation of the TLZ07 subsystem:
•

Choose a large block size when mounting a tape; 65534 is recommended.

•

The TLZ07 cassette tape subsystem uses the standard magnetic tape commands
that can be invoked under the OpenVMS operating system, Version 5.4-2 or later.
The OpenVMS commands used to operate the TLZ07 are:
•

ALLOCATE

•

INITIALIZE

•

MOUNT

•

BACKUP

•

COPY

•

DISMOUNT

•

DEALLOCATE

Operating the RRD43 CD–ROM and TLZ07 DAT Tape Drive 4–21

4.6.1 Using the ALLOCATE Command
The ALLOCATE command provides exclusive access to a device and optionally
establishes a logical name for that device. Once you have allocated a device, other
users cannot access that device until you explicitly DEALLOCATE it, or until you
log out. Use the following format to allocate the TLZ07 subsystem:
$ ALLOCATE device_name: [logical name]
For example, to allocate the TLZ07 subsystem for your use and assign it the
logical name TAPE1, do the following:
$ ALLOCATE MUA0: TAPE1

4.6.2 Using the INITIALIZE Command
CAUTION
When a tape is initialized, any data already on the tape will be destroyed.
Use the INITIALIZE command to specify the device name, and write a volume
name to the magnetic tape volume loaded into the TLZ07 tape drive. The tape
must be write-enabled for the initializing operation.
For the TLZ07, use the following format:
$ INITIALIZE device_name: [volume label]

As an example, to initialize the device MUA0 and assign the volume name
GMB001, type the following for the TLZ07:
$ INITIALIZE MUA0: GMB001
For the initialization to succeed, the cassette must not have been mounted (with
the MOUNT command).
For detailed information regarding volume names and magnetic tape operations,
see the Guide to VAX/VMS Disk and Magnetic Tape Operations (AA-M539A-TE).

4–22 Operating the RRD43 CD–ROM and TLZ07 DAT Tape Drive

4.6.3 Using the MOUNT Command
The MOUNT command lets you make a magnetic tape volume available for
processing. It loads the tape with the protection set according to the write-protect
switch on the cassette. It can determine the maximum block size on the TLZ07.
Use the following format to mount a tape on the TLZ07 subsystem for use with
the BACKUP utility:
$ MOUNT/FOREIGN/BLOCKSIZE=65534 device_name: [volume label] [logical name]

As an example, to make the device MUA0 available for processing on the TLZ07
and assign it the logical name TAPE1, type the following:
$ MOUNT/FOREIGN/BLOCKSIZE=65534 MUA0: GMB001 TAPE1

4.6.4 Using the BACKUP Command
The BACKUP command provides protection against file volume corruption by
creating backup copies.
Use the following format to back up a file on the TLZ07:
$ BACKUP/BLOCK=65534/ignore=(label) source:*.* tape:file.name

Operating the RRD43 CD–ROM and TLZ07 DAT Tape Drive 4–23

4.6.5 Using the COPY Command
Use the COPY command, with the TLZ07 subsystem, to copy files from tape.
In the following example, the MOUNT command requests that the volume labeled
GMB001 be mounted on the drive at MUA0 and assigns the logical name TAPE1.
The COPY command uses the logical name TAPE1 for the input file specification.
All files on MUA0 are copied to the current default disk and directory. The files
keep their original file names and file types.
Use the following format on the TLZ07:
$ MOUNT/BLOCKSIZE=65534 MUA0: GMB001 TAPE1:
$ COPY TAPE1:*.* *.*

4.6.6 Using the DISMOUNT Command
The DISMOUNT command cancels the previous MOUNT command, makes the
unit unavailable for processing, and unloads the tape.
Use the following format for the TLZ07:
$ DISMOUNT logical_name or device_name:

4.6.7 Using the DEALLOCATE Command
The DEALLOCATE command cancels the previous ALLOCATE command and
makes the unit available for other users. The following is an example of the
command:
$ DEALLOCATE MUA0: or TAPE1

4–24 Operating the RRD43 CD–ROM and TLZ07 DAT Tape Drive

4.6.8 OpenVMS TLZ07 Compression and Noncompression Modes
The default mode for the TLZ07 tape drive is noncompression mode. To use
the TLZ07 tape drive in compression mode, when installed on an HSD05,
use the /DENSITY= modifier. To select the noncompressed density, use
the /DENSITY=1600 modifier; to select the compressed density, use the
/DENSITY=6250 modifier. The selected density will be displayed in the SHOW
DEVICE/FULL display.
For initializing a tape on the TLZ07 in compression mode, use the following
format:
$ INITIALIZE/DENSITY=6250 device_name: [volume label]

As an example, to initialize the device MUA0 in compression mode and assign the
volume name OMEGA, type the following for the TLZ07:
$ INITIALIZE/DENSITY=6250 MUA0: OMEGA
