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 1).
b. Set the Power switch for each unit (both hosts for a dual-host system, and
any expanders for expanded systems) to on (1).
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. To display the DSSI devices on KFQSA-based DSSI
adapters, enter
SHOW UQSSP
.
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 DIA
u
or DIB
u
(MIA
u
or MIB
u
for the TF-series tape drive—devices on bus 0 are listed as
DIA, devices on bus 1 are listed as DIB—and
u
is a unique unit number. The
embedded DSSI host adapter for each bus is identified by an asterisk (*).
The following embedded DSSI display shows a system with four DSSI devices
(unit numbers 0–3) and an R400X expander with seven DSSI devices (unit
numbers 0–6).
