1.4 Setting the Device Configuration Switches
This section explains how to set the device configuration switches before you
install the adapter in BA400-based VAX 4000 systems.
The device configuration switchpack contains 10 switch elements, divided into
DSSI ID and SCSI ID sections as shown in Figure 1–1.

1–6 HSD05 Adapter Preparation

1.4.1 Selecting and Setting the DSSI ID
Each device on the DSSI bus requires a unique device address in the range of
0 through 7. The DSSI ID is factory set to 0; you may need to change this ID
to one that is currently not being used on your system.
Table 1–5 lists the DSSI ID sections of SW2 and the corresponding settings for
each DSSI ID (Closed = down position; Open = up position).

Use the following procedure to set the DSSI ID:
1. At the system console prompt, enter the console command SHOW DEVICE
to determine the DSSI ID numbers currently active on the DSSI bus.
2. Select an unused DSSI ID number for the HSD05 adapter.
3. Refer to Figure 1–1 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 switch to the DSSI
ID number selected in step 2.

HSD05 Adapter Preparation 1–7

1.4.2 Selecting and Setting the SCSI ID
The SCSI port plugs into the SCSI connector (J30) on the backplane when the
HSD05 adapter is installed in the card cage. This port must have a unique
SCSI ID.
The HSD05 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 most operations, you do not have
to reset the SCSI ID.
Table 1–6 lists the SCSI ID sections of SW2 and the corresponding settings for
each SCSI ID (Closed = down position; Open = up position).

5. Remove the existing DSSI and SCSI cables from the I/O panel located to
the left of slot 12 (Figure 2–4). Be sure to note how the cables are routed
so you can run the new cables in the same manner.
a. Remove any external cables or terminators from the connectors on the
panel.
b. Remove the small cable connector screws and remove the DSSI cable
from the panel (DSSI Bus 0).
Remove only the cable connector screws, adjacent to the connector,
that secure the cable to the plate. Do not remove the screws that
secure the plate to the panel.
Save the screws to attach the new cable.
c.

Remove the SCSI cable/plate from the panel (KZQSA IN) by removing
the top and bottom plate screws.

d. Disconnect the DSSI and SCSI cables from the backplane and remove
the cables from the enclosure.
Be careful not to break the cable clamps when removing the cables
from the enclosure. Additional clamps are provided in the HSD05
adapter kit if the original clamps breaks. Be sure to clean the
enclosure surface thoroughly (for example, with an alcohol wipe)
before attaching a new cable clamp.
Remove the SCSI cable by pulling it through the plate opening in
the I/O panel.
This completes the removal of the cables. Go to Section 2.2.2 to install the new
cables.

2.2.2 Installing the New DSSI and SCSI Cables
This section describes how to install the new DSSI and SCSI cables.
NOTE
If there is a KFDDB (3rd and 4th DSSI bus option) already installed in
slots 11 and 12, you can install the HSD05 adapter in the same slot as
the KFDDB bulkhead.

Installing the HSD05–JA/JF Adapter in a Pedestal Enclosure 2–9

1. Install the new 3-connector DSSI cable (refer to Figure 2–5 for the cable
routing).
a. Slip the short portion of the cable (plastic connector) up through the
opening to the left of slot 12 (slot 11 if the M9404–PA is installed),
left through the card cage/mass-storage divider, and up through the
opening next to the side of the enclosure.
Connect the cable to the DSSI connector (J29) on the backplane.
NOTE
The cable must be routed up to the left of the first card guide (shown
in Figure 2–5) or you may damage the cable if you try to install an ISE
into this slot. The cable must be run to the connector on the backplane
just as the original cable was run.

b. Slip the long section of the cable (metal connector) up through the
opening to the left of slot 12 (slot 11 if the M9404–PA is installed),
left through the card cage/mass-storage divider, and down through the
opening next to the side of the enclosure.
c.

Insert a connector screw (saved when you removed the original cable)
about 3/4 of the way into the bottom of the DSSI cable connector.
The wide side of the connector should be on the right side of the
panel opening.

d. Slip the connector into the DSSI opening (DSSI Bus 0) from the rear of
the I/O panel (the screw holds the connector in position).
e.

Insert the other connector screw into the top of the connector and then
tighten both screws.
The middle section of the cable should be hanging through the
opening above slot 12 (it is not connected at this time).
Route the cable through the 1st (small clamp closest to the DSSI
connector opening) and 3rd (wide) cable clamps on the side of the
enclosure that the original cable ran through (skip the 2nd small
clamp). Additional clamps are provided in the HSD05 adapter kit
if the original clamp breaks. Be sure to clean the enclosure surface
thoroughly (for example, with an alcohol wipe) before attaching a
new cable clamp.

2. Install the new SCSI cable (refer to Figure 2–6 for the cable routing):
a. Slip the end of the SCSI cable with the right-angle wires (connector
farthest from the cable ID label) up through the opening to the left
of slot 12 (slot 11 if the M9404–PA is installed), left through the card
cage/mass-storage divider and up through the opening next to the side
of the enclosure.
NOTE
The cable must be routed up to the left of the first card guide (shown
in Figure 2–6) or you may damage the cable if you try to install an ISE
into this slot. The cable must be routed through cable clamp and up
over the connectors on the backplane just as the original cable was run.

Connect the cable to the SCSI connector (J30) on the backplane.
Route the cable through the cable clamp on the side of the
enclosure. Additional clamps are provided in the HSD05 adapter
kit if the original clamp breaks. Be sure to clean the enclosure
surface thoroughly (for example, with an alcohol wipe) before
attaching a new cable clamp.
The other end of the cable should be hanging through the opening
above slot 12 (it is not connected at this time).
Go to Section 2.2.3 to install the HSD05 adapter into the enclosure.

Refer to Figure 2–7 to insert the HSD05 adapter into the enclosure.
1. Insert the HSD05 adapter half-way into slot 12 (or slot 11 if necessary).
2. Pull the DSSI and SCSI cables through the opening in the HSD05 adapter.
Use the SCSI opening on the I/O panel to access the cables by slipping
a few fingers in the SCSI opening to help coax the cables through the
opening in the HSD05 adapter.
3. Connect the SCSI cable to the SCSI connector.
4. Connect the DSSI cable to the DSSI connector.
5. Push the HSD05 adapter all the way into the slot until it makes a positive
connection to the backplane. Use the module handles to seat the adapter
securely.
6. Check the cables from the HSD05 adapter making sure they are routed
sharply to the left and through the opening on the adapter so they do not
interfere with a module placed in an adjacent slot.
NOTE
If you have the KFDDB option installed, the card cage/mass storage
divider will be very crowded with cables. Try to keep the cables for
each device separated. For example, if your HSD05 adapter cables are
located at the back of the divider openings, place the KFDDB cables at
the front of the openings. Cables should be routed at the front and rear
edges leaving the center of the card cage/mass storage divider clear so
that airflow through the unit is not impeded.

10. Remove the screws on each side of the DSSI connector (leave the connector
plate in place). Set the DSSI connector screws aside. See
in Figure 3–4.
11. Remove the SCSI and DSSI cables. The easiest way to remove the SCSI
and DSSI cables is by pulling the cable out by the connector end on the
right side of the chassis, and routing the cables through the cutout in the
leftmost ISE slot. The DSSI cable/connector must be first dropped into the
enclosure and then removed. See ( in Figure 3–4).

3.2.5 Installing the New DSSI and SCSI Cables
To install the new (longer) DSSI and SCSI cables, follow these steps:
1. Each module slot is numbered in the card cage. Note slots numbered 11
and 12 (shown as white numbers on black squares) in Figure 3–5.
2. If there are modules in slots 9 through 12, you need to remove them. Be
sure to mark all cable connections to the modules and list the module and
its particular slot location. It may be helpful to draw a diagram of the
module/slot configuration to simplify the installation process.
CABLING TIPS
•

The HSD05 adapter is normally installed in slot 12. If your
system contains an option such as the M9404–PA Q–bus
extender that must go in slot 12, then install the HSD05
adapter in slot 11.

•

If your system contains only a few modules, route the cables to
either the left or right of the HSD05 module. Figure 3–6 shows
the cables being dressed to the right of the module.

•

If your system contains many modules, the HSD05 cables will
be less likely to interfere with other modules if they are dressed
to the left of the module slot selected for the HSD05 adapter.
For example, if you plan to place the HSD05 module in slot 11,
route the cables to the left, through slot 12. If you plan to place
the HSD05 module in slot 12, route the cables to slot 12.

This completes the installation of the adapter in a rackmount enclosure. Go to
Appendix A to select device numbers and complete the installation.

Installing the HSD05–JG/JH Adapter in a Rackmount Enclosure 3–13

A
Selecting Device Numbers for Multiple
DSSI Bus Configurations
Use the following procedure to select a unique device number for the HSD05
adapter and the SCSI ISE devices connected to it.
1. At the system console prompt, enter the console command ‘‘SHOW DSSI’’
to verify that the selected HSD05 adapter node address is seen by the
system.
2. Take note of the DSSI device numbers in use on the cluster to be sure that
all DSSI numbers are unique throughout the cluster. For example, you
cannot have a DIA130 and a DIB130 on the same cluster.
The device numbering scheme on the HSD05 adapter is ‘‘wxyz.’’
‘‘w’’ is the value of the HSD05 UNIT_OFFSET parameter (default = 0)
‘‘x’’ is the DSSI ID (default = 0)
‘‘y’’ is the SCSI ID
‘‘z’’ is the SCSI lun number (usually = 0)
In this example the device name is DIA1230.
HSD05 UNIT_OFFSET (w) = 1
DSSI ID (x) = 2
SCSI ID (y) = 3
SCSI lun (z) = 0

Selecting Device Numbers for Multiple DSSI Bus Configurations A–1

NOTE
You may need to change the UNITUM and FORCEUNI parameters
on existing DSSI drives in the cluster and the HSD05 UNIT_OFFSET
parameter so that each device has a unique device number.
If a unit number is added which overlaps the unit number of another
device on another controller in the system or cluster, all of the other
devices on that other controller can disappear. In this event, the unit
number conflict should be resolved and controller power should then be
cycled. All lost devices will reappear when the controller is powered on.

3. At the command prompt, enter the console command ‘‘SET HOST/DUP
/DSSI/BUS:n x PARAMS’’ to set the DISK_ALCS and TAPE_ALCS
parameters to the cluster Allocation class.
Where n = DSSI bus number and where X = the DSSI node name of the
HSD05 adapter.
4. Set the UNIT_OFFSET so that unit numbers are unique across the cluster
(default = 0).
5. Set the HSD05 NODENAME and any other desired parameters.
6. Use the WRITE and RESTART commands to save the settings and
complete the procedure.
7. Install any new SCSI disk, tape, or CD–ROM drives in the BA4xx
enclosure, making sure the SCSI IDs are unique.
Refer to the BA400-Series Enclosures Storage Devices Installation
Procedures manual (EK–BA44A–IN) for the procedures to install
HSD05 adapter supported options.

A–2 Selecting Device Numbers for Multiple DSSI Bus Configurations

8. Enter the console command ‘‘SHOW DSSI’’ or ‘‘SHOW DEVICES’’ to verify
that all devices are seen by the system.
You may have to enter this command twice in order to see all of the
devices on the system.
NOTE
All disk drives appear as RF72s while all tape drives appear as TU81s.
The OpenVMS command ‘‘SETHOST/DUP/SERVER=MSCP$DUP
/TASK=<taskname> <node>’’ can be used in place of the console
command ‘‘SET HOST/DUP/DSSI/BUS:n PARAMS’’, once the VMS
driver is loaded, by using the command ‘‘MC SYSGEN CONNECT
FYA0/NOADAPTER.
Where n = the DSSI bus number.’’

This completes the installation of the HSD05 adapter. Refer to the HSD05
DSSI-To-SCSI Adapter Operation Information for BA400-Based VAX
4000 Systems (EK–HSDC5–IN) for system operating and troubleshooting
information.
