Microsoft Windows Server 2003 Cluster Server Integration

Cluster Recovery
This chapter describes some common scenarios, which can be manually fixed and don’t require an
Automated System Recovery (ASR).
Cluster Disks
Shared disks use the disk signature to identify a disk and to map the real device to a physical disk
resource. When a physical disk resource fails and is replaced, the signature of the newly formatted
disk no longer matches the signature stored by the physical disk resource.
Cluster and quorum disks can be recovered with the Microsoft Windows Server 2003 Resource Kit
tool ClusterRecovery, which substitutes the newly created physical disk resource for the failed
resource. The properties of the failed resource are automatically transferred to the new resource. Any
dependencies on the old resource are changed to point to the new resource.
Note: In case of a failed quorum disk, the cluster service must be started with parameter
“/fixquorum”.
The following two figures show a recovery of disk resource “Disk F:”. Before executing
ClusterRecovery, the new disk resource must be visible to the same set of nodes as the old resource.
