Recommended Action
Accelerator status: Obsolete data sensed at reset
Accelerator status: Obsolete data was written to drives
Accelerator status: Obsolete data was discarded
Accelerator status: Dirty data detected. Unable to write dirty data to drives
Accelerator status: Dirty data detected has reached limit. Cache still enabled, but writes no longer being posted
Accelerator status: Excessive ECC errors detected in at least one cache line. As a result, at least on cache line is no longer in use
During reset initialization obsolete data was found in the cache. This was due to the drives being moved and written to by another controller.
During reset initialization obsolete data was found in the cache. The obsolete data was written to the drives, but newer data may have been overwritten.
During reset initialization obsolete data was found in the cache and it was discarded (not written to the drives).
At least one cache line contains dirty data that the controller has been unable to flush (write) to the drives. This problem usually occurs when there is a problem with the drive(s).
The number of cache lines containing dirty data that cannot be flushed (written) to the drives has reached a preset limit. The cache is still enabled, but writes are no longer being posted. This problem usually occurs when there is a problem with the drive(s).
At least one line in the cache is no longer in use due to excessive ECC errors detected during use of the memory associated with that cache line.
Nothing needs to be done. The controller will either write the data to the drivers or discard the data completely. Normal operations should continue.
If newer data was overwritten, you may need to restore newer data; otherwise, nothing needs to be done. Normal operations should continue.
Nothing needs to be done. Normal operations should continue.
Fix the problem with the drive(s). Then the controller will be able to write the dirty data to the drives.
Fix the problem with the drive(s). Then the controller will be able to write the dirty data to the drives and posted write operations will be restored.
Replacement of the cache should be considered. If cache replacement is not done the remaining cache lines should continue to operate properly.

Check to be sure that the array accelerator is properly seated. If the error continues you may need to replace the array accelerator.
