3.6.2 Resetting the SCSI ID on the Second RRD42 Expansion Box
If you add two RRD42 expansion boxes to your system, you must reset the ID
number on the second RRD42 to an open ID — one that is not currently being
used. To reset the number, follow instructions in step 3 of Section 3.4. In the
following example, ID 0 is an open ID.
To determine available ID numbers on the SCSI-A or SCSI-B bus on your
InfoServer 150 system, enter TEST 50 at the console prompt
(>>>)
, then press
Return. Your system configuration appears on the screen. FFFFFF05 indicates
an open SCSI ID number. Look for a display similar to the following:
SCSI-A
1C1C.0001
V1.3
FFFFFF05 00000001 05000001 FFFFFF05 FFFFFF05 FFFFFF05 FFFFFF03 FFFFFF05
