002A Verify failed
This message indicates that the data integrity verification function (see
message 0029) has terminated with an error. For each RAID level being
verified, this may mean:
•
Single, JBOD, and Spare. A single drive returned an error, possibly
because of a media defect.
•
RAID 0. A single drive returned an error, possibly because of a media
defect.
•
RAID 1. One side of the mirror does not equal the other side.
•
RAID 10. One side of the mirror does not equal the other side.
•
RAID 5 and 50. The parity data does not equal the user data.
For any RAID type, the most likely cause of the error is a grown defect in the
drive. For out-of-synchronization mirrors or parity, the error could be caused
by improper shutdown of the unit. This possibility applies to RAID 1, 10, 5,
and 50. A rebuild will re-synchronize the unit
When this message is generated, redundant units will be automatically
initialized. The initialize will not erase user data, but will recalculate and
rewrite user parity data. For more information on the Initialize function, see
“About Initialization” on page 148.
002B Verify completed
This message indicates the data integrity verification function (see message
“0029 Verify started” on page 233) was completed successfully.
002C Source drive ECC error overwritten
If a read error is encountered during a rebuild and the controller is configured
to ‘ignore ECC’ or to ‘Force continue on source errors’, the sector in error is
reallocated. You are notified of the event by this message.
002D Source drive error occurred
If an error is encountered during a rebuild operation, this message is generated
if the error was on a source drive of the rebuild. Knowing if the error occurred
on the source or the destination of the rebuild is useful for troubleshooting.
002E Replacement drive capacity too small
The 3ware RAID controller notifies you by this message when the
replacement drive capacity is smaller than required. The replacement drive
must be equal to or greater capacity than the drive it is replacing.
