Stop cluster services on the secondary node. 2. Shut down the secondary node. 3. If the cluster quorum disk is physically damaged, perform the following steps: a. Shut down the primary node. b. Replace cluster non-quorum shared disk with new disks. c. Restart the primary node. d. Have your checklist handy. e. Recreate the partitions on the non-quorum shared disk. f. Format the partitions according to BrightStor Cluster Disaster Recovery check list. 4. Start the cluster service on the primary node. At this point, the cluster service startup fails. 5.

Recovering All Shared Disks with No Nodes Failures in the Cluster
You can use one of two ways to recover your cluster quorum disks. Use the first
method to recover your quorum disk using the integrated cluster support included
in the option.
Method 1
If cluster nodes are not Active Directory servers:
1.
Stop cluster services on the secondary node.
2.
Shut down the secondary node.
3.
If the cluster quorum disk is physically damaged, perform the following steps:
a.
Shut down the primary node.
b.
Replace cluster non-quorum shared disk with new disks.
c.
Restart the primary node.
d.
Have your checklist handy.
e.
Recreate the partitions on the non-quorum shared disk.
f.
Format the partitions according to BrightStor Cluster Disaster Recovery
check list.
4.
Start the cluster service on the primary node. At this point, the cluster service
startup fails.
5.
To start the cluster service on primary node, enter:
%windir%\cluster\clussvc -debug -noquorumlogging
Now the cluster shared disk is accessable.
6.
Restore the system state backup. In BrightStor ARCserve Backup, select
System State session, and right-click to select the local option. The System State
Restore Options dialog opens.
7.
Restore the lost shared disk by performing a whole volume restore in
BrightStor ARCserve Backup.
8.
