IBM 220 manual Diagnostic programs and error messages, Scsi Messages Description

Table 14. SCSI messages

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 server.

• The cables for all external SCSI devices are connected correctly.

• The last device in each SCSI chain is terminated properly.

• The SCSI devices are configured correctly.

If the above items are correct, run the diagnostic programs to obtain additional information about the failing device. If the error remains or recurs, call for service.

Diagnostic programs and error messages

The server diagnostic programs are stored in upgradeable read-only memory (ROM) on the system board. These programs are the primary method of testing the major components of your server.

Diagnostic error messages indicate that a problem exists; they are not intended to be used to identify a failing part. Troubleshooting and servicing of complex problems that are indicated by error messages should be performed by trained service personnel.

Sometimes the first error to occur causes additional errors. In this case, the server displays more than one error message. Always follow the suggested action instructions for the first error message that appears.

The following sections contain the error codes that might appear in the detailed test log and summary log when running the diagnostic programs.

The error code format is as follows:

fff-ttt-iii-date-cc-text message

where:

fffis the three-digit function code that indicates the function being tested when the error occurred. For example, function code 089 is for the microprocessor.

tttis the three-digit failure code that indicates the exact test failure that was encountered. (These codes are for trained service personnel and are described in the Hardware Maintenance Manual.)
