Note: Microsoft recommends that shared disks on the cluster provide some level of redundancy to protect against disk failures (such as RAID-1 or RAID-5), however, in catastrophic cases disk recovery may be necessary.
A server cluster has a special disk known as the quorum disk. This disk is used to store cluster configuration and such things as resource checkpoint files. The quorum disk needs additional work to recover in the event of a failure and we will cover that separately.
Note: This recovery procedure is ONLY valid for disks that are managed in the cluster using the physical disk resource type. The recovery procedures for other types of cluster disk will vary depending on the configuration and the features. You should contact your vendor if you are using disks that are not exposed to the cluster as physical disk resource types.
