Recommended Action
Resolve the problem with the drive or drives, and
then the controller can write the dirty data to the
drives.
Consider replacing the cache. If cache
replacement is not done, the remaining cache
lines should continue to operate properly.
Try reseating the cache to the controller. If not
successful, replace the cache.
Normal operations should continue. The
controller either writes the data to the drives or
discards the data completely.
Normal operations should continue.
If newer data was overwritten, you may need to
restore newer data; otherwise, normal operation
should continue.
Check the Disable Code field. Run the ACU to
reinitialize the array accelerator board.
There is no way to determine if dirty or bad data
was in the cache and is now lost.
Check the Disable Code field.
