Cause: The diskgroup is being dismounted by request or
because an I/O error was encountered that could not be
handled by taking the disks offline. A disk cannot be
offlined whenever doing so could result in all copies of a
redundant extent being unavailable.

Action: Repair the hardware problem and re-mount the
diskgroup. Refer to the alert log to determine which disks
have failed.
