During the recovery from a failure, Sun StorEdge 3310/3510/3511 FC array controllers may incorrectly offline good drives causing multiple drive failures. As a result, logical devices may become degraded thereby causing applications to stop running.

Note: This issue can be triggered by a marginal link or a drive failure.

This issue can occur on the following platforms:

SPARC Platform

• Sun StorEdge 3310 FC array without patch 113722-10
• Sun StorEdge 3510 FC array without patch 113723-10
• Sun StorEdge 3511 FC array without patch 113724-04

Should the described issue occur, messages similar to the following can be found in the Sun StorEdge 3310/3510/3511 event log:

    [1115] #16334: StorEdge Array SN#8014709 CH2 ID11: SCSI Drive ALERT: unexpected
    sense received (02h, 05h,21/00)

The above message indicates that the drive with ID11 has rejected the command from the controller as an "illegal request". This will be followed by a message indicating that the drive has failed:

    [2101] #16427: LD-ID 16469417 on StorEdge Array SN#8014709: ALERT: SCSI drive  
    failure (CH0 ID11)

Note: This issue can occur on multiple drives.

There is no workaround. Please see the "Resolution" section below.
