The server had a disk added, and then the operator realized they put the disk in the wrong server, so they pulled it out again. No harm done, the server is running and the disk was never actually accessed from the OS, but the Fault LED went on, and the IMM (Integrated Management Console) shows this "Active Event":
The Drive 5 has been removed from unit disk or disk bay 5.
Since we don't need the drive (and indeed don't have it anymore), we want to clear this alert. I've tried clearing the event log, and it did remove the "disk inserted" and "disk removed" events, but neither the Fault LED nor the "Active Event".
How can I clear the Fault LED and tell the server to just accept that there is no disk in bay 5?
