Recommended Action
Replacement of cache should be considered. If
cache replacement is not done remaining cache
lines should continue to operate properly.
Normal operations should continue. The
controller will either write data to the drives or
discard the data completely.
Normal operations should continue.
If newer data was overwritten, you may need to
restore newer data; otherwise, normal
operations should continue.
Check the Disable Code field. Run Array
Configuration Utility (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.
Obtain the latest version of ADU.
Not an error or data loss condition; no action
required
Replace the Array Accelerator board.
