SCSI Messages
SCSI Messages
The following table lists messages that reflect problems with the
SCSI controller or SCSI device.
Note: If your server does not have a hard disk drive, ignore any
message that indicates that the BIOS is not installed.
SCSI Messages Description
All One or more of the following might be causing the problem.
Ÿ
A failing SCSI device (adapter, drive, controller)
Ÿ
An improper SCSI configuration or SCSI termination
jumper setting
Ÿ
Duplicate SCSI IDs in the same SCSI chain
Ÿ
A missing or improperly installed SCSI terminator
Ÿ A defective SCSI terminator
Ÿ An improperly installed cable
Ÿ A defective cable
Action: Verify that:
Ÿ
The external SCSI devices are turned on. External
SCSI devices must be turned on before the system.
Ÿ
The cables for all external SCSI devices are
connected correctly.
Ÿ
If you have attached an external device to the
server's external SCSI connector, the external SCSI
termination jumper (J29) is set to the proper
position (see Table 2 on page 211).
Ÿ The last device in each SCSI chain is terminated
correctly. (See “Working with Internal Drives” on
page 77 for more information about SCSI
termination.)
Ÿ The SCSI devices are configured correctly.
If the above are correct, run the diagnostics for additional
information about the failing device. If the error recurs, have
the system serviced.
