Example B–2 shows a sample KFQSA-based DSSI bus.
Example B–2:
SHOW UQSSP Display (KFQSA-Based DSSI)
>>>SHOW UQSSP
UQSSP Disk Controller 0 (772150)
-DUA0 (RF31)
UQSSP Disk Controller 1 (760334)
-DUB1 (RF31)
UQSSP Disk Controller 2 (760340)
-DUC2 (RF31)
UQSSP Disk Controller 3 (760322)
-DUD3 (RF31)
UQSSP Tape Controller 0 (774500)
-MUA0 (TK70)
For the examples in this appendix, each device will be assigned an
allocation class of 2, and the system disk will be given a new node name.
Also, devices MIA0, DIA1, DIA2, and DIA (or DUA0, DUB1, DUC2, and
DUD3) will be assigned new unit numbers.
NOTE:
The DUP server examples throughout this appendix are for RF-series
ISEs. The displays for the TF85 tape drive differ slightly from the RF-series
displays.
B.3.1 Entering the DUP Driver Utility
To examine and change DSSI parameters, you must first activate the DUP
driver utility by setting host to the specific device for which you want to
modify or examine parameters.
Use the following command for embedded DSSI:
SET HOST/DUP/DSSI <NODE_NUMBER> PARAMS
where:
<node_number> is the bus node ID (0–6) for the device on the bus.
Use the following command for KFQSA-based DSSI:
SET HOST/DUP/UQSSP/DISK <controller_number> PARAMS
where:
<controller_number> is the controller number (provided by the SHOW
UQSSP display) for the device on the bus.
