3-37 DAAD Diagnostic Messages Continued Message Description Accelerator status: Obsolete data sensed at reset During reset initialization obsolete data was found in the cache. This was due to the drives being moved and written to by another controller. Recommended Action Nothing needs to be done. The controller will either write the data to the drivers or discard the data completely. Normal operations should continue. Accelerator status: Obsolete data was written to drives During reset initialization obsolete data was found in the cache.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. If newer data was overwritten, you may need to restore newer data; otherwise, nothing needs to be done. Normal operations should continue. Accelerator status: Obsolete data was discarded During reset initialization obsolete data was found in the cache and it was discarded (not written to the drives). Nothing needs to be done. Normal operations should continue. Accelerator status: Dirty data detected. Unable to write dirty data to 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). Fix the problem with the drive(s). Then the controller will be able to write the dirty data to the drives. Accelerator status: Dirty data detected has reached limit. Cache still enabled, but writes no longer being posted 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). 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. 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. 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. Replacement of the cache should be considered. If cache replacement is not done the remaining cache lines should continue to operate properly. Accelerator status: Data in the cache was lost due to some reason other than the battery being discharged Data in the cache was lost, but not because of the battery being discharged. Check to be sure that the array accelerator is properly seated. If the error continues you may need to replace the array accelerator.
