0025 Cache flush failed; some data lost
To improve performance, the 3ware RAID controller features caching layer firmware. For write commands this means that it acknowledges it has completed a write operation before the data is committed to disk. If the 3ware RAID controller can not commit the data to the media after it has acknowledged to the host, this message is posted.
Typically, the Cache Flush Failed notification would be an indication of a catastrophic failure of the drives in the unit, such as loss of power to multiple drives in a unit.
To troubleshoot the reasons for the failure, collect the logs for your system and contact 3ware technical support at http://www.3ware.com/support/ index.asp. For information on what error logs are and how to collect them, see http://www.3ware.com/KB/article.aspx?id=12278.
