One or more of the following might be causing the problem:
±
A failing SCSI device (adapter, drive, controller)
±
An improper SCSI configuration or SCSI termination jumper
setting
±
Duplicate SCSI IDs in the same SCSI chain
±
A missing or improperly installed SCSI terminator
±
A defective SCSI terminator
±
An improperly installed cable
±
A defective cable
Action:
Verify that:

more information about SCSI termination.
±
The SCSI devices are configured correctly.
If the above are correct, run the diagnostic programs for
additional information about the failing device.
If the error
recurs, have the system serviced.
