Bug Id
<SUNBUG: 4817349>, <SUNBUG: 5094897>, <SUNBUG: 4994282>

Date of Workaround Release
30-NOV-2004

Date of Resolved Release
17-OCT-2007

Impact

In the event of a disk failure, disk rebuilding would commence on the spare drive (if configured) and the rebuilding may stop after 99% and not complete. The rebuild will remain incomplete and the logical device state would remain as degraded. Should another drive failure occur, this condition could result in loss of data integrity.


Contributing Factors

This issue can occur on the following platforms:

  • Sun StorEdge 3310 SCSI array without 4.11k firmware (as delivered in patch 113722-10)
  • Sun StorEdge 3510 FC array without 4.11i firmware (as delivered in patch 113723-10)
  • Sun StorEdge 3511 FC array without 4.11i firmware (as delivered in patch 113724-04)

Symptoms

A disk failure is followed by disk rebuilding which stops at 99% and does not proceed. There are no indications from the system that this condition has occurred.


Workaround

Notes:

  1. The relief/workaround below is only valid for rebuilds that have reached 99 percent. Any other percentage less than 99 percent indicates a different issue and this relief/ workaround process is not valid.
  2. Before attempting to utilize the relief/workaround below, insure that the logical disks status is degraded. The relief/workaround below does not work with the logical disk at any other status level.

To work around the described issue: if the disk rebuild process is hung, reset the array (through the "sccli" utility) and restart the rebuild. The rebuild will then complete without incident. Resetting the controller through the telnet(1) or serial port interfaces, or performing a hard reset, does not flush the cache. Only the reset done through the "sccli" utility will properly flush the cache.

Note: Any disks that failed prior to resetting the array must be removed in order to prevent the failed disk from reassuming the role of a valid disk in the Logical Drive.


Resolution

This issue is addressed on the following platforms:

  • Sun StorEdge 3310 SCSI array with 4.11k firmware (as delivered in patch 113722-10 or later)
  • Sun StorEdge 3510 FC array with 4.11i firmware (as delivered in patch 113723-10 or later)
  • Sun StorEdge 3511 FC array with 4.11i firmware (as delivered in patch 113724-04 or later)

Internal Comments


From Engineering:



This problem is reported by a few customers and one of the bugs was closed as "Not Reproduceable". The other bugs are under investigation and the state not sure if this will be fixed in the upcoming 4.11 firmware due to the difficulties in replicating this problem.



Bug 5094897 is currently being investigated by the PDE/Dothill and the resolution is pending completion.



See Bugs 4817349, 5094897 4994282.
