SCSI Messages
Description
All
One or more of the following might be causing the problem.
A failing SCSI device (adapter, drive, controller)
An improper SCSI configuration
Duplicate SCSI IDs in the same SCSI chain
An improperly installed SCSI terminator
A defective SCSI terminator
An improperly installed cable
A defective cable
Action: Verify that:
The external SCSI devices are turned on. External
SCSI devices must be turned on before the system.
The cables for all external SCSI devices are
connected correctly.
The last device in each SCSI chain is terminated
correctly. (See “SCSI Drives” on page 218 for more
SCSI chain information.)
The SCSI devices are configured correctly.
When you daisy chain two banks in a disk-array
model, you must start the ServeRAID configuration
program and specify which channel the banks are
connected to. You must also define the SCSI IDs
for each bank as LO or HI. (See “Changing the
ServeRAID Adapter Parameters” on page 124 for
more information.)
If the above are correct, run the diagnostics for additional
information about the failing device. If the error recurs, have
the system serviced.
