0024 Buffer integrity test failed

Background Information
The 3ware RAID controller supports a feature called dynamic sector repair
that allows the unit to recover from certain drive errors that would normally
result in a degraded unit situation. For redundant units such as RAID 1, 5, 6,
10, and 50, the 3ware RAID controller essentially has two copies of your data
available. If a read command to a sector on a disk drive results in an error, it
reverts to the redundant copy in order to satisfy the host's request. At this
point, the 3ware RAID controller has a good copy of the requested data in its
cache memory. It will then use this data to force the failing drive to reallocate
the bad sector, which essentially repairs the sector.
Action
Sector repairs are an indication of the presence of grown defects on a
particular drive. While typical modern disk drives are designed to allow
several hundred grown defects, special attention should be paid to any drive in
a unit that begins to indicate sector repair messages. This may be an indication
of a drive that is beginning to fail. You may wish to replace the drive,
especially if the number of sector repair errors exceeds 3 per month.
Event Type
Error.
Cause
The 3ware RAID controller performs diagnostics on its internal RAM devices
as part of its data integrity features. Once a day, a non-destructive test is
performed on the cache memory. Failure of the test indicates a failure of a
hardware component on the 3ware RAID controller. This message is sent to
notify you of the problem.
Action
You should replace the 3ware RAID controller.
If the controller is still under warranty, contact 3ware Technical Support for a
replacement controller.
