ABSTRACT:
A storage controller and associated disk or disk portion where after the controller terminates its access to said disk or disk portion, data integrity problems in the disk or disk portion can be detected. Before host data associated with a write command is written from the cache memory to the disk or disk portion, an identity of the storage controller as a current user of the disk or disk portion and indication that the controller is operating in a mode it stores data in a cache is recorded on the disk or disk portion. If the storage controller is shut down abnormally, the record of the identity of the controller and the indication are not cleared. The storage controller is restarted or rebooted and the record is read to learn that the controller was using the disk or disk portion and operating in the foregoing mode before the shutdown.
