Sun Microsystems 280R manual DVD/CD-ROM or Scsi Drive Failure, Run the test command, type

1.At the ok prompt, type:

ok probe-scsi

If a message is displayed for each installed disk, the system FC-AL controllers have successfully probed the devices. This indicates that the main logic board is working correctly.

2.Use the test command to get more information, type:

ok test /SUNW,qlc

3.Take one of the following actions depending on what the probe-scsicommand reports:

a.If one drive does not respond to the FC-AL controller probe but the others do, replace the unresponsive drive.

b.If only one internal disk drive is configured with the system and the probe-scsitest fails to show the device in the message, replace the drive.

4.If the problem is still evident after replacing the drive, replace the main logic board.

5.If replacing both the disk drive and the main logic board does not correct the problem, replace the associated FC-AL data cable and FC-AL backplane.
