Best Practices for managing Veritas System Recovery (VSR)

Best practices for capturing recovery point images with Veritas System Recovery in a Windows server cluster environment include the following:
Installing Veritas System Recovery on all nodes within the Microsoft Windows server cluster.

The Veritas Recovery Disk (SRD) may not be able to identify the shared storage volume when booted in pre-OS mode. Hence, recovery points of a cluster node should not be stored on a shared storage volume.  This can be tested first by booting a node in the cluster with the SRD.

In most cases, recovery points of the operating system should be stored on a volume other than the shared storage, such as local disk drives, separate Windows server shares, or NAS devices that are not shared by the cluster. Visit here; Veritas System Recovery.

Restoring a Single Node in Cluster

To restore recovery points of a node in the cluster, perform the following steps:

1. Boot the Veritas Recovery Disk on the node that needs to be restored.
2. It can be difficult to determine which physical volume to restore to since drive letters are likely assigned differently than they are in Windows. If there is any confusion about if the volume is local to the node that is being restored, then temporarily disconnect any external storage.
3. Restore the recovery point of the operating system volume. Make sure that the option to recover the original disk signature is selected so that the drive letter mappings will be preserved. If the option is available select the option to restore the domain trust token.
4. Start the server into Windows OS.
Verify that connections to the shared storage are active.

Restoring an Entire Cluster

To restore recovery points of an entire cluster, perform the following:

1. Take all the cluster nodes offline.
2. Restore one cluster node from the Veritas Recovery Disk as per the above steps.
3. Boot the cluster node into Windows, and restore the Quorum volume to its original location on the shared storage (note that a Microsoft Quorum volume can only exist on a basic disk). If Restoration of a Quorum volume failed, refer to the related article ( 000020338).
4. Either restart into Windows to restore the shared storage volumes(s) or restore them from the SRD. Note that the data volumes are easier to identify in Windows.
5. In Windows re-establish the shared storage connections.
6. Restore the remaining nodes using the Veritas Recovery Disk.
7. Verify that the cluster is running properly.

What is supported?

Supported Operations In a server cluster environment for Microsoft Windows, Veritas System Recovery provides support for the following operations: Creation and Restoration of an active node OS Recovery Point in a multi-node cluster.

Creation and Restoration of a passive Node OS Recovery Point in a multi-node cluster.Creation and Restoration of a Quorum Disk volume recovery Point. Restoration of Quorum Disk volume recovery points should be done within Windows, due to volume order and driver letter assignments being unpredictable when booting to the SRD.
