Recovering a Failed Quorum Disk
This section describes the procedure for recovering a failed quorum disk. The
procedure requires the following:
• The quorum disk is designated for exclusive use by MSCS.
• The quorum disk resides in a drive array that is not a RAID.
• A spare disk, identical in type to the quorum disk, must be available to
replace the failed disk. The spare disk must have at least as much total
disk space as the quorum disk that is being replaced.
• The new quorum disk must be assigned the same drive letter as the failed
disk.
