3.8 Connecting Systems Into a DSSI VAXcluster
Configuration
Note
A DSSI VAXcluster configuration is supported only under VMS Version
5.5-1HN or later.
A DSSI VAXcluster configuration consists of two or more systems configured
as a DSSI VAXcluster and sharing their DSSI devices through a Digital
Storage System Interconnect (DSSI) bus. See Figure 3–8 and Figure 3–9 for
connections. Each system can have direct access to any of the devices on the
DSSI bus, including a shared system disk.
The simplest DSSI VAXcluster configuration, a two-system configuration, can
let one system disk be used as the system disk for both systems. Although the
system disk resides in one system, both systems have equal access to it and to
any other DSSI storage device in either system.
A DSSI device, such as the RF35, has a built-in DSSI VAXcluster capability
that can dynamically serve two or more systems. DSSI adapters, embedded in
the system CPU, let you extend a DSSI bus by connecting it to another system.
Using an external DSSI cable, DSSI-based systems can be connected to form a
DSSI VAXcluster configuration.
The benefits of a DSSI VAXcluster configuration:
•
VAXcluster features such as shared data across systems and satellite nodes
are available to you.
•
Higher system availability — If one of the systems is unavailable due to a
system malfunction, the satellites booted through it can continue operating
through the other system.
If one system fails, all satellite nodes booted through that system lose
connections to the system disk. Each satellite knows that the system disk
is available through a second path. The satellite nodes establish a new
connection through the other system and continue operation.
To increase system availability, a second system disk can be added to each
boot node. If one system disk fails, the other system disk continues to serve
one system and the satellite nodes booted through it. As in any VAXcluster, a
second system disk improves availability but increases system management
tasks.
3–16 Network Information
Figure 3–8 shows how to attach a DSSI cable. Figure 3–9 shows a typical

Hardware Options
This chapter describes the hardware options of the VAX 4000 Model 100A. It
also describes how to connect the external hardware options to the system. It
includes information on the following topics:
•
Internal hardware options
•
External hardware options
•
Connecting a SCSI expansion box
•
Connecting peripherals
4.1 Internal Hardware Options
The system supports the following internal hardware options:
•
MS44L-BC 16MB set (4XMS44L-AA) and MS44-DC 64MB set (4XMS44CA) memory modules—The Model 100A system does not have any memory
on the system board. It uses only MS44L-BC and MS44-DC memory
module bundles. You can increase the memory capacity of the Model 100A
system up to a maximum of 128MB in 16MB or 64MB increments using a
maximum of two memory sets.
•
Synchronous communications options—The system supports the DSW42AA synchronous communications option. This communications option
provides two synchronous communications ports and allows you to connect
the system to a peripheral that uses an EIA-232 (V.24) 25-pin connector.
You can use other interface standards with this option if you order different
cables. Table 4–1 lists each interface standard and the part number of the
corresponding cable.

The BC19x-02 cables listed in Table 4–1 are 2-foot cables; extension cables
are also available, but you must order them separately. Contact your
Digital Sales representative for information on ordering any of the different
cables that support these interface standards.
•
Asynchronous communications options—The system supports three
different asynchronous communications options. These options are as
follows:
–
DHW42-AA—This asynchronous option provides eight asynchronous
DEC423 data-line-only communications lines through one system port.
You can connect up to eight peripherals using the MMJ ports on the
harmonica (H3104) that connects to the option cable (BC16C-10).
–
DHW42-BA—This option is the same as the DHW42-AA, but provides
16 asynchronous DEC423 data-line-only communications lines through
two system ports. You can connect up to 16 peripherals using the MMJ
ports on two harmonicas (H3104) that connect to the option cables
(BC16C-10).
Use the following cables instead of the BC16C-10 cable if you require
longer cable lengths: BC16C-25, BC16C-50, BC16C-A0, or BC16C-B5.
Use the following cables between the harmonica (H3104) and the DEC423
peripheral: BC16E-10, BC16E-25, or BC16E-50.
–
DHW42-CA—This asynchronous option provides eight asynchronous
EIA-232 modem control lines through two system ports using two
breakout cables (BC29J-06).
–
DHW42-UP—This upgrade option converts a DHW42-AA asynchronous
option to a DHW42-BA option.
4–2 Hardware Options
Attach one of the following cables to a connector on the breakout cable if
you require longer cable lengths: BC22F-10, BC22F-25, or BC22F-50. The
peripheral you are using may require a null-modem extension cable. See
the peripheral documentation or contact your Digital Sales representative
for information on the correct null-modem cable to use.
•
DSSI hard disk drives, including the RF31T, the RF35, and the RF36.
•
SCSI storage devices, including the following removable devices:
•
–
TLZ06 tape drive
–
TZK10 (QIC) tape drive
–
TZ30 tape drive
–
RRD42 compact disc drive
Digital Storage Systems Interconnect (DSSI)– The KA52 CPU module
contains one DSSI bus connector that is dedicated to the mass storage
devices in your system.
A DSSI connector provides a path to the DSSI bus through which the CPU
can communicate with DSSI devices.
The DSSI bus has the following characteristics.
–
A 4-Mbytes-per-second bandwidth
–
Up to eight nodes (one interface and up to seven additional DSSI
Devices (RF-series ISEs, TF85s, and adapters))
–
Eight data lines
–
One parity line
–
Eight control lines
DSSI architecture improves system performance as follows.
–
Each device queues requests and each performs seek ordering.
–
Mass storage devices can act independently, since each device contains
its own controller. Several devices can work simultaneously.
An ISE can maintain connection to more than one DSSI interface. That feature
allows ISEs to be shared by multiple CPUs in a DSSI VAXcluster configuration.
For more information about DSSI VAXcluster configurations and the
advantages of such configurations, see the section on DSSI VAXcluster
capability in your system Operation manual.
Hardware Options 4–3
4.2 External Hardware Options

4–4 Hardware Options
4.4.1 Guidelines for Connecting Expansion Boxes
Use the following guidelines when connecting expansion boxes:
•
The recommended maximum length of the SCSI cables (internal length
plus external length) is 19.6 feet (6 metres).
•
Each device in the expansion boxes and the system box must have a unique
SCSI ID.
•
You must attach the 50-pin terminator that comes with the expansion box
to an unused SCSI connector on the back of an expansion box.
•
Plug the expansion boxes into the same grounded power strip or electrical
circuit as the system.
•
Do not connect more than two tape drive devices.
Caution
–
Some expansion boxes are restricted to either 110 V ac or 220
V ac operation. Make sure that the voltage requirement of the
expansion box used is compatible with the supply voltage.
–
Turn on the expansion boxes before you turn on the 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 the configuration display.
–
Do not connect or disconnect SCSI expansion boxes while
the system is turned on. Doing so can cause damage to the
equipment or corrupt data.
–
Digital cannot guarantee the correct operation of any SCSI
bus that uses cable assemblies not supplied by Digital or not
configured in accordance with these guidelines.

4.5.4 Connecting Peripherals to an Optional Synchronous Port
If the system has the DSW42-AA synchronous communications option
installed, the system has two synchronous modem ports. Section 4.1 gives
more information on the DSW42-AA synchronous communications option.
Table 4–1 lists the cables that you can use with the option. The EIA-232/V.24
cable (BC19D-02) is the standard cable shipped with the option. If you are
using a synchronous interface standard other than EIA-232/V.24, use one of the
optional cables listed in Table 4–1.
To connect a peripheral to a synchronous port, follow these steps:
1. Set the on/off switch on the peripheral to the off (O) position.
2. Connect the 50-pin connector of the option cable to one of the synchronous
ports on the back of the system unit (see Figure 4–8).
3. Connect the other connector of the option cable to the communications port
on the peripheral.
4. If the option cable connectors are fitted with screws, secure the connectors
to the ports by tightening them on each side.
5. Set the on/off switch on the peripheral to the on ( | ) position.

Removable Storage Media
This appendix contains information on the use and storage of the following
media types that are used by the optional removable media storage devices:
•
Tape cartridges
•
QIC tapes
•
Cassette Tapes (DAT)
•
Compact discs
B.1 Tape Cartridges
The CompacTape cartridge (see Figure B–1) is a 10 cm by 10 cm (4 inches by
4 inches) plastic tape 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 has tighter tolerances than the CompacTape, which support
the higher recording densities of the TK70. The CompacTape and the
CompacTape II (when used with TZ30 and TK50 tape drives) have a capacity
of 95MB.
The TZ30 can use a CompacTape or CompacTape II cartridge that was
originally written by the TK50. If a CompacTape II cartridge written by a
TK70 is used on a TZ30, the TZ30 automatically unloads the tape cartridge,
because the TZ30 cannot read the tape cartridge. The green LED flashes,
indicating a tape error.

B.1.1 Labeling a Tape Cartridge
Always label tape cartridges. There is a slot for the label on the front of the
cartridge. See Figure B–2. The label is visible when the cartridge is in the
drive. Labels or markings on any other part of the cartridge can interfere with
the proper operation of the drive. Do not write on the cartridge with a pen,
pencil, or other marking instrument.
The labels supplied with the CompacTape II cartridges have spaces that mark
the capacity of the tape cartridge. If a TK50 or TZ30 wrote data to the tape
cartridge, mark the 95MB block on the label. If a TK70 wrote data to the tape
cartridge, mark the 296MB block on the label.
If you use TK70 and TZ30 drives, note that the TZ30 is unable to read or write
tapes that have originally been written to by the TK70. However, the TK70
can read tapes written by the TZ30 or the TK50.

B.1.2 Writing to and Write-Protecting Tape Cartridges
CompacTape and CompacTape II cartridges have a write-protect switch that
prevents an accidental overwrite of data. 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.
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 by sliding it left towards
the label until it locks in place (see Figure B–3). An orange rectangle appears
when the write-protect switch locks in the write-protect position.
Writing to a Tape
When you use a tape to make a backup copy or to write data, set the writeprotect switch to the write-enable position. To set the switch to the writeenable position, slide it to the right, away from the label, until the switch locks
in place.
B.1.3 Handling and Storing Tape Cartridges
Inside the cartridge, a 600-foot single reel of magnetic tape stores data.
A plastic tape 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.
•
Do not drop the tape cartridge.
•
Allow tape cartridges to reach room temperature before using them.
•
Store the tape where the room temperature is between 10°C and 40°C
(50°F and 104°F) and the humidity is between 20% and 80%.
•
Place the identification label in the slot provided on the tape cartridge.
•
Store the tape cartridge in its plastic cover.
•
Do not expose the tape to direct sunlight, heat, magnetic fields, or X-rays.

Programming Parameters for DSSI Devices
This appendix describes the console mode procedures for setting and examining
parameters for DSSI devices.
Note
Before you reprogram DSSI devices, you should have a good
understanding of DSSI architecture and VAXcluster software
operation. If you do not have that understanding, you should read
the VMS manuals listed in Appendix A or call your Digital service
representative.
On the VAX 4000 Model 100A system, a DSSI daughter card (KFDDA–AA)
provides two DSSI interface adapters between the KA52 CPU and the DSSI
storage devices.
Each of the two adapters on the KFDDA-AA daughter card provides a DSSI
bus that can support up to eight nodes, where the adapter and each DSSI
storage device counts as one node, hence each DSSI adpater can support up to
seven DSSI storage devices (six DSSI storage devices for a two-system DSSI
VAXcluster; five DSSI storage devices for a three-system DSSI VAXcluster
configuration). The adapters make a connection between the CPU and the
requested device on their respective DSSI bus. Each DSSI device has its
own controller and server that contain the intelligence and logic necessary to
control data transfers over the DSSI bus.
Programming Parameters for DSSI Devices C–1
C.1 DSSI Device Parameters
Seven principal parameters are associated with each DSSI device:
•
Bus Node ID
•
ALLCLASS
•
UNITNUM
•
FORCEUNI
•
NODENAME
•
SYSTEMID
•
DSSI NODE ID
Each of these seven parameters, with the exception of the Bus Node ID, are
programmed and examined using the console-based Diagnostic and Utility
Program (DUP) driver utility. The Bus Node ID is physically determined by
jumpers on disk drive.
A brief description of each parameter follows.
The Bus Node ID parameter is provided by the jumpers on the disks. Each
DSSI bus can support up to eight nodes, 0–7. Each DSSI adapter and each
device count as a node. Hence, in a single-system configuration, a DSSI bus
can support up to seven devices, bus nodes 0–6 (with node 7 reserved for the
adapter); in a two-system DSSI VAXcluster configuration, up to six devices,
0–5 (with nodes 6 and 7 reserved for the adapters); in a three-system DSSI
VAXcluster configuration, up to five devices, 0–4 (with nodes 5, 6, and 7
reserved for the adapters).
The ALLCLASS parameter determines the device allocation class. The
allocation class is a numeric value from 0 to 255 that is used by the VMS
operating system to derive a path-independent name for multiple access paths
to the same device. The ALLCLASS firmware parameter corresponds to the
VMS SYSGEN parameter ALLOCLASS.
DSSI devices are shipped from the factory with a default allocation class of
zero. Each device to be served to a cluster should have a nonzero allocation
class that matches the allocation class of the system. Refer to the VMS
VAXcluster manual for rules for specifying allocation class values.
The UNITNUM parameter determines the unit number of the device. By
default, the device unit number is supplied by the jumpers on the drives.
Systems with multiple DSSI busses, as described later in this section, require
that the default values be replaced with unique unit numbers. To set unit
numbers and override the default values, you use the console-based DUP
C–2 Programming Parameters for DSSI Devices
driver utility to supply values to the UNITNUM parameter and to set a value
of zero to device parameter FORCEUNI.
The FORCEUNI parameter controls the use of UNITNUM to override the
default device unit number supplied by the jumpers. When FORCEUNI is
set to a value of zero, the operating system uses the value assigned to the
UNITNUM parameter; when FORCEUNI is set to a value of one, the operating
system uses the value supplied by the jumpers.
The NODENAME parameter allows each device to have an alphanumeric node
name of up to eight characters. DSSI devices are shipped from the factory with
a unique identifier, such as R7CZZC, R7ALUC, and so on. You can provide
your own node name.
The SYSTEMID parameter provides a number that uniquely identifies the
device to the operating system. That parameter may need to be modified only
when replacing a device. Only Digital service representatives and licensed
self-maintenance customers should remove devices.
DSSI NODE ID is the unique number held by one DSSI node within one DSSI
bus. See Figure C–1 and Table C–1 for instructions for setting the DSSI Node
ID.

C.2 How VMS Uses the DSSI Device Parameters
This section describes how the operating system uses the parameters to form
unique identifiers for each device. Configurations that require you to assign
new unit numbers for devices are also described.
With an allocation class of zero, the operating system can use the default
parameter values to provide each device with a unique device name. The
operating system uses the node name along with the device logical name in the
following manner.
NODENAME$DIAu
where NODENAME is a unique node name, and u is the unit number.
With a nonzero allocation class, the operating system relies on unit number
values to create a unique device name. The operating system uses the
allocation class along with the device logical name in the following manner.
$ALLCLASS$DIAu
where ALLCLASS is the allocation class for the system and devices, and u is a
unique unit number.
Figure C–2 illustrates the need to program unit numbers for a system using
more than one DSSI bus and a nonzero allocation class. In the case of the
nonzero allocation class, the operating system sees three of the integrated
storage elements (ISEs) as having duplicate device names, which is an error,
as all unit numbers must be unique.

For one of the DSSI busses, the unit numbers need to be reprogrammed to avoid this error.
MLO-007176
Note
You should configure your system to have unique unit numbers even if
you have a standalone system using an allocation class of zero. That
practice will avoid problems with duplicate device names if you later
decide to form a cluster.
Programming Parameters for DSSI Devices C–5
C.3 Examining and Setting DSSI Device Parameters
The following instructions describe how to change DSSI parameters, using the
DUP driver utility. In the example procedures, the allocation class will be set
to 2.
1. Enter the console mode.
The procedure for programming parameters for DSSI devices from console
mode requires that you issue commands to those devices at the console
prompt >>>. You may enter the commands in either uppercase or lowercase
letters. Unless otherwise instructed, enter each command, then press
Return.
Enter console mode as follows.
a. Set the Break Enable/Disable switch on the system console module to
the enable position (up, position | ).
b. Set the Power switch for each unit (both hosts for a dual-host system,
and any expanders for expanded systems) to the on position ( | ).
Wait for the system to display the console prompt (>>>).
2. To display the DSSI devices on embedded DSSI adapters, enter SHOW DSSI
at the console prompt.
The firmware displays two lines of information for each device. For
embedded DSSI, the firmware displays the following.
•
The first line contains the bus number, node number, and node name.
•
The second line contains the device name and unit number followed by
the device type in parentheses.
For embedded DSSI, the device name consists of the letters DIAu or DIBu
(MIAu or MIBu for the TF-series tape drive. Devices on bus 0 are listed as
DIA. The embedded DSSI host is identified by an asterisk (*).

C.3.6 Exiting the DUP Server Utility
After you have completed setting and examining DSSI device parameters, enter
the WRITE command at the PARAMS> prompt to save the device parameters
you have changed using the SET command. The changes are recorded to
nonvolatile memory.
If you have changed the allocation class or node name of a device, the DUP
driver utility will ask you to initialize the controller. Answer Yes (Y) to allow
the changes to be recorded and to exit the DUP driver utility.
If you have not changed the allocation class or node name, enter the EXIT
command at the PARAMS> prompt to exit the DUP driver utility for the specified
device.
This shows the procedure for saving parameter changes. The controller is
initialized.
PARAMS>WRITE
Changes require controller initialization, ok? [Y/(N)] Y
