Action: If a physical disk was removed from the disk group, either replace the disk or restore the original
disk. On some controllers, a removed disk has a red X for its status. On other controllers, a removed disk
may have an Offline status or is not displayed on the user interface. Perform a rescan after replacing
or restoring the disk. If a disk has not been removed from the disk group, then check for problems with
the cables. See the online help for more information on checking the cables. Ensure that the enclosure is
powered on. If the problem persists, check the enclosure documentation for further diagnostic
information.
