Identifying disk problems through SEERs

Identifying common

disk problems through

SEERs

The disk manager reports disk problems in a Class 66 SEER.

The complete list of SEERs can be found in Meridian Mail

Maintenance Messages (SEERs) Guide (NTP 555-7001-510).

The purpose of this section is to give further details of the

most common SEERs.

Note: The errors described may also be caused by a defective

SCSI controller on the Enhanced MMP40 or MMP40 card.

Sense key SEERS

A SEER in the form “6603/6605 Disk #> sense key: # error

code: # [block: #]”

displays when a disk reports a problem. The sense key

describes the general nature of the problem and is not drive or

manufacturer dependent. There may be an optional disk

block number associated with the problem report.

Sense key 2 indicates that the disk is not ready to accept

commands. One possible cause is that the drive will not spool

up. If this appears during regular operation, the disk should

be replaced.

Sense key 3 normally indicates a medium error. Disk

controller problems can also cause this sense key to appear. A

block number is provided with this problem report. Use the

“scsi util” verify command to check that the block is indeed

bad. The disk drive should be replaced.

Sense key 4 indicates a disk hardware failure. Replace the

disk drive.

Sense key 5 indicates that an invalid command was sent to the

drive. If this appears during regular operation, replace the

disk drive and contact Nortel support.

Sense key 6 indicates that the SCSI bus has been reset. If this

appears during regular operation, contact Nortel support.
