TIP To enable automatic restore of all shared disk volumes in the MSCS
using OBDR method, move all volumes temporarily to the node for which
you are preparing OBDR boot tape. It is namely impossible to collect
enough information to configure the disk in Phase 1 for shared disk
volumes that are locked by another node.
2. Reboot the computer.
3. Restore the cluster database. MSCS database is part of the
CONFIGURATION on Windows. See “Restoring the Windows
CONFIGURATION” on page 280.
NOTE The MSCS service must be running in order to be able to restore the
MSCS database. Therefore it can not be restored automatically during
Phase 2 of disaster recovery. However, the cluster database can be
restored at the end of Phase 2 using the standard Data Protector restore
procedure.
4. Make the IDB consistent if you are recovering a Cell Manager. See
“Making IDB consistent (all methods)” on page 487.
5. The quorum and IBD volumes are restored. All other volumes are left
intact and are claimed by the recovered primary node if they are not
corrupted.
If they are corrupted you have to:
a. disable the cluster service and cluster disk driver (the steps
required to do so are described in MSDN Q176970)
b. reboot the system
c. reestablish the previous storage structure
d. enable the cluster disk driver and cluster service
e. reboot the system
f. restore user and application data
6. Restore the remaining nodes. See “Disaster Recovery of a Secondary
Node” on page 491.
