4–30 Troubleshooting
■●❍●●●❍
2E Multiple cabinets have the same SCSI
ID.
More than one cabinet have the same
SCSI ID .
Reconfigure PVA ID to uniquely-
identify each cabinet in the
subsystem. The cabinet with the
controllers must be set to
PVA ID 0; additional cabinets must
use PVA IDs 2 and 3. If error
continues after PVA settings are
unique, replace each PVA module
one at a time. Check cabinet if
problem remains.
■●❍●●❍●
2D All master cabinet SCSI buses are not
set to ID 0.
Set PVA ID to 0 for the cabinet with
the controllers. If problem persists,
try the following repair actions:
1. Replace the PVA module.
2. Replace the EMU.
3. Remove all devices.
4. Replace the cabinet.
■●❍●●❍❍
2C Cabinet IO termination power out of
range.
Faulty or missing IO module causes
cabinet IO termination power to be out
of range.
Ensure that all of the cabinet’s
device SCSI buses have an I/O
module. If problem persists, replace
the failed I/O module.
■●❍●❍●●
2B Jumpers not terminators found on
backplane.
One or more SCSI bus terminators are
either missing from the backplane or
broken.
Ensure that cabinet’s SCSI bus
terminators are installed and that
there are no jumpers. Replace the
failed terminator if the problem
continues.
