Disaster Recovery

Advanced Recovery Tasks

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.

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.
