Product
Sun StorageTek 3310 SCSI Array
Sun StorageTek 3510 FC Array
Sun StorageTek 3511 SATA Array

Bug Id
<SUNBUG: 5022022>

Date of Workaround Release
03-AUG-2004

Date of Resolved Release
30-AUG-2005

Impact

In some rare cases, multi-bit DRAM parity errors or multi-bit SDRAM ECC errors on Sun StorEdge 3310, Sun StorEdge 3510 or 3511 FC arrays may cause loss of file system integrity.

Note: There is a very low probability for the occurrence of this issue.


Contributing Factors

This issue can occur on the following platforms:

  • Sun StorEdge 3310 array without patch 113722-11
  • Sun StorEdge 3510 array without patch 113723-10
  • Sun StorEdge 3511 FC array without patch 113724-04

This issue can occur when the controller firmware fails to distinguish between single-bit ECC errors and multi-bit ECC errors. The controller seems to continue to work normally even for multi-bit errors, which leads to loss in file system integrity. A single-bit ECC error is recoverable, while a multi-bit ECC error is not.

Note: This issue may only occur when SE3310, SE3510 or SE3511 arrays encounter multi-bit DRAM parity errors or multi-bit SDRAM ECC errors. Single-bit parity or ECC errors would not encounter this issue.


Symptoms

Should the described issue occur, DRAM parity error messages similar to following are logged in SCCLI event log:

    [0104] #4287: StorEdge Array SN#xxxxxxx Controller ALERT: DRAM parity error detected

SDRAM error messages similar to following are logged in "/var/adm/messages" file:

    Mar 19 18:30:23  SUNWscsdMonitor[628]: [ID 298706 daemon.error]
[SUNWscsd 0x10B1D0D: Critical] <rctrl6003> Controller Event,  SDRAM  Error.
Likely controller error. If error persists, replace defective controller.
(Primary, Fri Mar 19 18:23:36 2004) {SN#00369b}
.

Mar 20 04:21:20  SUNWscsdMonitor[628]: [ID 739865 daemon.error]
[SUNWscsd 0x10B1D0D: Critical] <rctrl6003> Controller Event,  SDRAM  Error.
Likely controller error. If error persists, replace defective controller.
(Primary, Sat Mar 20 04:14:25 2004) {SN#00369b}

Workaround

There is no workaround for this issue. Please see the Resolution section below.


Resolution

This issue is addressed on the following platforms:

  • Sun StorEdge 3310 with patch 113722-11 or later
  • Sun StorEdge 3510 with patch 113723-10 or later
  • Sun StorEdge 3511 (FC) with patch 113724-04 or later
