002C Source drive ECC error overwritten
002D Source drive error occurred
256
Event Type
Error
Cause
A read error was encountered during a rebuild and the controller is configured
to 'ignore ECC' or to 'Force continue on source errors'. The sector in error
was reallocated.This will cause uncorrectable blocks to be rewritten, but the
data may be incorrect.
Action
It is recommended that you execute a file system check when the rebuild
completes.
Under Windows, right-click on your drive icon and choose
Tools >> Check Now.
For Mac OS X, you can use the First Aid tab in the Disk Utility—select the
disk on the left and then click Verify Disk. If verification encounters
problems, you can then use the Repair Disk option on the same screen.
Under Linux and FreeBSD use the fsck command.
For OpenSolaris and VMware you should follow your operating system's
guide to perform a file system check.
Event Type
Error
Cause
An error on the source drive was detected during a rebuild operation. The
rebuild has stopped as a result.
Action
The controller will report an error, even if the area of the source drive that had
the error did not contain data. Scheduling regular verifies will lessen the
chance of getting this error.
You can force the rebuild to continue by setting the Overwrite ECC Error
policy through 3DM2, 3BM, or CLI, and then rebuilding the unit again. This
will cause uncorrectable blocks to be rewritten, but the data may be incorrect.
