Disk subsystem check

Checking the disk

subsystem

A stage 3 failure could indicate a disk problem as well as a

SCSI problem.

To check for problems in the disk subsystem, follow these

steps.

Step Action

1 Power down the system.

2 Remove the suspected faulty disk drive.

3 Check the external SCSI cable to make sure it is

secure.

4 Ensure that the SCSI ID on the back panel of the

external tape drive is set to 1. If it is accidentally set

to 0 or 2, it will interfere with disk drive addressing.

5 Replace the disk.

6 Restart the system and perform a restore (for non-

shadowed systems) or a disk sync (for shadowed

systems) as described in the

System Installation and

Modification Guide

(NTP 555-7001-215).

7 See the sections on disk unit replacement in

Chapter 16, “Hardware maintenance,” and review

Chapter 17, “Common disk subsystem problems.”
