In the history alarms, no alarm relevant to hard disks exists.
In the history events, no event relevant to hard disks exists.
In the system logs, the following messages exist:
2009-09-14 20:18:02  Operation  WebUI  User admin:Logout.
2009-09-14 20:14:47  Operation  WebUI  User admin:Disk light on successfully, (subrackID,slotID) is (00, 0)
2009-09-14 20:14:23  Operation  WebUI  User admin:Login. IP is
The messages indicate that a user logged in to the storage device at 2009-09-14 20:14:47, turned on the disk location indicator, but forgot to turn it off before logging out. As the disk location indicator and alarm indicator share the same one, the hard disk is misjudged as faulty.
