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

 

Ÿ Duplicate SCSI IDs in the same SCSI chain

 

Ÿ An 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 The last device in each SCSI chain is terminated

 

correctly. (See “SCSI Drives” on page 159 for more

 

SCSI chain information.)

 

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.
