Solution  1000214.1 :   Sun StorEdge 3510 FC Array May Lose In-band Connectivity After Generating Parity Regeneration on the Secondary Controller  


PreviouslyPublishedAs
200287

Product
Sun StorageTek 3510 FC Array

Bug Id
<SUNBUG: 4916011>

Date of Workaround Release
04-FEB-2004

Date of Resolved Release
23-MAR-2004

Impact

On a Sun StorEdge 3510 FC Array, running parity regeneration on a logical drive from the GUI may never finish the parity regeneration process on the secondary controller. As a result all the disks in the logical drive may not be available.

Contributing Factors

This issue can occur in the following releases:

SPARC Platform

• Sun StorEdge 3510 FC Array without patch 113723-07

Note: This issue only occurs if the logical drive (ld0) is mapped to the primary controller, and the other logical drives are mapped to the secondary controller.

Symptoms

When a parity check is scheduled from the GUI to run to several logical drives in one array, the array will run these parity checks sequentially starting with "ld0" and continuing upward. The parity check running on the secondary controller never completes and the last logical drive to run will show disk lights blinking green indicating activity when there should not be any activity occuring (no I/O to the logical drive).

Workaround

To work around the described issue, arrange the ordering of the logical drives such that the last logical drive is assigned to the primary controller if possible.

Resolution

This issue is addressed in the following releases:

• Sun StorEdge 3510 FC Array with patch 113723-07 or later
