Product
Sun StorageTek 3510 FC Array

Bug Id
<SUNBUG: 6319828>

Date of Workaround Release
19-OCT-2005

Date of Resolved Release
02-NOV-2005

Impact

Certain internal disk drives (listed below) installed in Sun StorEdge 3510 FC Arrays with firmware version 4.11I or higher may stop responding to requests during a controller failover event which results in an initialization of the drive loop.

Firmware version 4.11I and higher has a data integrity enhancement feature called Media Scan. Initialization of the drive loop during Media Scan under some corner case conditions may cause the drive to hang and the controller to mark the drive as "BAD" or offline it.

Logical devices that contain one "BAD/USED" device will become degraded. A logical device with more than one "BAD/USED" device will be flagged as "failed" and data may be lost.


Contributing Factors

This issue can occur on the following platforms:

  • Sun StorEdge 3510 FC Array with firmware version 4.11I or later

with one of the following disk drives installed:

  • MAP3147FC (146.8GB-10000 RPM FC-AL) without patch 116815-07
  • MAP3735FC (73.4GB-10000 RPM FC-AL) without patch 116514-09
  • MAS3735FC (73.4GB-15000 RPM FC-AL) without patch 116817-04
  • MAS3367FC (36.4GB-15000 RPM FC-AL) without patch 116816-04

Note: The described issue can occur on a Sun StorEdge 3510 FC Array running 3.27R firmware, but the risk is low at this firmware version.

To determine if a Sun StorEdge 3510 FC Array contains one of the drives mentioned above, use the sccli command line as shown:

    sccli> show disks
    Ch     Id      Size   Speed  LD     Status     IDs

To determine the Sun StorEdge 3510 FC Array firmware revision, the following command can be used:

    sccli> show rev
Vendor: SUN
Product: StorEdge 3510
Revision: 411I
Peripheral Device Type: 0x0

 


Symptoms

If the described issue occurs, one or more of the affected drives will show as "BAD" when checking "sccli show disks" output after an initialization on the fiber channel loop.

Example:

    sccli show disks
    Ch  Id   Size     Speed  LD     Status    IDs                Rev
  ----------------------------------------------------------------
  2   0   68.37GB   200MB  ld0    ONLINE    SUN    S/N 00050680xxxx
  2   1   68.37GB   200MB  ld0    ONLINE    SUN    S/N 00050680xxxx
  2   2   68.37GB   200MB  NONE   USED      SUN    S/N 00050680xxxx
  2   3   68.37GB   200MB  ld0    ONLINE    SUN    S/N 00050680xxxx

Workaround

Drives experiencing this issue can be re-used by re-seating the drive, which will then come up as a "USED" state. A manual rebuild would be needed to make the drive active again on the logical drive. If there is a spare drive configured at the time of failure, the spare drive would have taken over for the failed drive.


Resolution

This issue is addressed in the following disk drives:

  • MAP3147FC (146.8GB-10000 RPM FC-AL) with patch 116815-07 or later
  • MAP3735FC (73.4GB-10000 RPM FC-AL) with patch 116514-09 or later
  • MAS3735FC (73.4GB-15000 RPM FC-AL) with patch 116817-04 or later
  • MAS3367FC (36.4GB-15000 RPM FC-AL) with patch 116816-04 or later
