You can restore the MSCS database after all nodes have been recovered and have
joined the cluster to ensure its coherency. The MSCS database is part of the
CONFIGURATION on Windows. See online Help index: “restore of configuration
objects”.
Disaster recovery of the primary node
In this case all nodes in the MSCS are unavailable and the cluster service is not
running.
The following must be true in addition to other prerequisites for disaster recovery:
• the primary node must have write access to the quorum disk (the quorum disk
should not be locked)
• the primary node must have write access to all IDB volumes, when recovering the
Cell Manager
• all other nodes must be shut down until all physical disk resources are online
In this case, restore the primary node with the quorum disk first. The IDB has to be
restored as well if the Cell Manager has been installed in the cluster. Optionally you
can restore the MSCS database. After the primary node has been restored, you can
restore all remaining nodes.
NOTE:
The MSCS service uses a hard disk signature written into the MBR of every hard disk to
identify physical disks. If the shared cluster disks have been replaced, this means that
the disk signatures were changed during Phase 1 of disaster recovery. As a consequence,
the Cluster Service will not recognize the replaced disks as valid cluster resources, and
cluster groups depending on those resources will fail. See “Restoring hard disk signatures
on Windows” on page 101 for more information.
Perform the following steps to restore the primary node:
