System Setup and Configuration
3.8 Firmware Commands and Utilities Used in System Configuration
For KFQSA-based DSSI, the firmware displays the following:
• The first line contains the UQSSP disk controller number and device node
name.
• The second line contains the device name and unit number followed by the
device type in parentheses.
For KFQSA-based DSSI, the device name consists of the letters DU
cu
,
where
c
is the controller letter, and
u
is a unique unit number.
Example 3–2 shows a sample KFQSA-based DSSI bus.
Example 3–2 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)

-MUA0 (TK70)
For the examples in this section, each device will be assigned an allocation
class of 1, and the system disk will be given a new node name. Also, devices
DIA0, DIA1, and DIA2; and DUA0, DUB1, DUC2, and DUD3 will be assigned
new unit numbers.
Note
The DUP server examples throughout this section are for RF-series
ISEs. The displays for the TF85/TF86 tape drive differ slightly from
the RF-series displays.
3.8.3.3 Entering the DUP Driver Utility from Console Mode
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.
