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.
Event Type
Error
Cause
The 3ware RAID controller was not able to commit data to the drive(s) during
a caching operation.This is due to a serious drive failure, possibly from a
power outage.
Background Information
The 3ware RAID controller uses caching layer firmware to improve
performance. For write commands this means that the controller
acknowledges it has completed a write operation before the data is committed
to disk. If the 3ware RAID controller cannot commit the data to the drive after
it has acknowledged to the host, this message is posted.
Action
To troubleshoot the reasons for the failure, collect the logs for your system
and contact 3ware technical support at
