Example 2–2 Self-Test Results on the SCSI-A Bus
If a Self-Test Indicates an Error
The error may be on the RX23 drive, on the other drives on the SCSI-A
bus, or on the SCSI-A bus controller. To determine which device is faulty,
examine the status codes of the individual drives. The SCSI IDs are
numbered 0 through 7 from left to right (for example, the RZ23 disk drive
is located at SCSI ID 2 and the RX23 diskette drive is located at SCSI ID
5). Table 2–3 lists the normal status codes for each SCSI device available
on the SCSI bus.
Any code other than those listed indicates an error in the device at that
SCSI ID.

If a drive’s status code indicates FFFFFF05, check the drive’s
cabling and power, then retest. If the code is still FFFFFF05 after
retesting, then replace the drive.
