Diagnostics and Troubleshooting 3-35 Table 3-18 Array Diagnostic Utility (ADU) Error Messages continued Message Description Recommended Action 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 or drives. Resolve the problem with the drive or drives, and then the controller can write the dirty data to the drives. Accelerator status: Excessive ECC errors detected in at least one cache line. As a result, at least one cache line is no longer in use. At least one line in the cache is no longer in use due to excessive error checking and correcting (ECC) errors detected during use of the memory associated with that cache line. Consider replacing the cache. If cache replacement is not done, the remaining cache lines should continue to operate properly. Accelerator status: Excessive ECC errors detected in multiple cache lines. As a result, the cache is no longer in use. The number of cache lines experiencing excessive ECC errors has reached a preset limit. Therefore, the cache has been shut down. Try reseating the cache to the controller. If not successful, replace the cache. Accelerator status: Obsolete data detected During reset initialization, obsolete data was found in the cache. This was due to the drives being moved and written to by another controller. Normal operations should continue. The controller either writes the data to the drives or discards the data completely. Accelerator status: Obsolete data was discarded During reset initialization, obsolete data was found in the cache, and was discarded (not written to the drives). Normal operations should continue. Accelerator status: Obsolete data was flushed (written) to drives During reset initialization, obsolete data was found in the cache.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, normal operation should continue. Accelerator status: Permanently disabled Array accelerator board has been permanently disabled. It remains disabled until it is reinitialized using the Array Configuration Utility (ACU). Check the Disable Code field. Run the ACU to reinitialize the array accelerator board. Accelerator status: Possible data loss in cache Possible data loss detected during power up due to all batteries being below sufficient voltage level and no presence of the identification signatures on the array accelerator board. There is no way to determine if dirty or bad data was in the cache and is now lost. Accelerator status: Array accelerator board has been Temporarily disabled temporarily disabled. Check the Disable Code field. continued
