WARNING - Drive Write Cache is Enabled on X
Description: Drive has its internal write cache enabled. The drive may be a
third-party drive, or the operating parameters of the drive may have been altered.
Condition can cause data corruption if power to the drive is interrupted.
Action: Replace the drive with a supported drive or restore the operating
parameter of the drive.
WARNING: Storage Enclosure on SCSI Bus X Indicated it is Operating in Single
Ended Mode...
...SOLUTION: This usually occurs when a single-ended drive type is inserted into an
enclosure with other drive types; and that makes the entire enclosure operate in single
ended mode. To maximize performance replace the single-ended drive with a type that
matches the other drives.
Description: One or more single-ended mode SCSI drives are installed in an
external storage unit that operates in LVD mode.
Action: The array continues to operate, but installing all LVD drives maximizes
performance.
Write Memory Error
Description: Data cannot be written to the cache memory. This typically means
that a parity error was detected while writing data to the cache. This can be
caused by an incomplete connection between the cache and the controller. This is
not a data loss circumstance.
Action: Power down the system and be sure that the cache board is fully
connected to the controller.
