Solution Type Sun Alert Sure Solution 1001199.1 : DRAM Parity Errors or SDRAM ECC Errors on Sun StorEdge 3310, Sun StorEdge 3510 or 3511 FC Arrays May Cause File System Integrity Issue
PreviouslyPublishedAs 201594 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:
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.
