Symptoms

After a failed disk drive is replaced, the new disk reports as Optimal, however, the alarm for the disk failure never clears.

Event Code       : XX.66.1023

Description       : Drive Tray.YY.Drive.ZZ failed.

This problem is only known to occur in 25x0 and 6xx0 arrays running 7.x versions of controller firmware.

Changes

The failed Disk Drive was replaced in the array.

Cause

The problem occurs when the disk is a member of a Virtual Disk (aka Volume Group) that has NO associated volumes. Since there is no data to reconstruct, the array does not clear the failed drive condition.

Solution

Verify the alarm.

# ./sscs list alarm ... Alarm Id : alarm352 Severity : Critical Type : 6180.ProblemEvent Topic : Tray.85.Drive.01 Event Code : 90.66.1023 Date : 2012-10-04 07:31:56 Device : 6180-1[SUN.16502-00.1T54402516] Description : Drive Tray.85.Drive.01 failed. State : Open Acknowledged By : - Auto Clear : Y Aggregated Count : 0 ... #
Verify the drive is part of a Virtual Disk by first listing the Virtual Disks in the array:

# ./sscs list -a 6180-1 vdisk Virtual Disk: 1 #
Verify that the Virtual Disk has no volumes in it by listing the details of that Virtual Disk(s):

# ./sscs list -a 6180-1 vdisk 1 Virtual Disk: 1 Status: Optimal State: Ready Number of Disks: 5 RAID Level: 5 Hot Spare Coverage: No Total Capacity: 544.911 GB Configured Capacity: 0.000 MB Available Capacity: 544.911 GB Array Name: 6180-1 Array Type: 6180 Disk Type: Fibre Channel Security: Non-secure Maximal Volume Size: 544.910 GB Associated Disks: Disk: t85d01 Disk: t85d02 Disk: t85d03 Disk: t85d04 Disk: t85d05 #

In the above example, we can see that the failed drive (Tray.85.Drive.01) is associated with this Virtual Disk but that there is no configured capacity.
Delete and the Virtual Disk:

# ./sscs delete -a 6180-1 vdisk 1 # ./sscs list -a 6180-1 vdisk #

Note: so long as no volumes are associated with the Virtual Disk - no data will be lost.

Wait for at least 5 minutes for the problem to clear, if the problem persists, please contact Oracle support for further assistance.
