Perform bare-metal recovery of Windows clusters

Bare-metal recovery (BMR) can restore a Windows cluster configuration. BMR restores only the system state and critical disks on the cluster nodes.

Prerequisites

  • The shared disk data and user data are protected using the relevant application agents.
  • The hardware configuration of the cluster-node Windows clients is recorded. Necessary information includes the hardware vendor, size and type of disks, type of NIC, and amount of memory assigned.

About this task

To restore the system state and critical disks on the cluster nodes, perform the following steps.

Steps

  1. If the old cluster-node Windows clients are powered on, power them off.
  2. Create two new Windows clients with the same hardware configuration as the old cluster-node Windows clients.
  3. Perform BMR on both of the new Windows clients.
  4. Power on the Windows clients.
  5. Open the Failover Cluster Manager and wait for the cluster to be connected.
  6. Open Disk Management and initialize the new critical disks with the same configuration and labels as the old critical disks.
  7. For each non-Cluster Shared Volume disk, perform the following substeps:
    1. Perform a file-system restore.
    2. Select the disk, and then click More Actions > Repair, replacing the disk.
    3. Select the disk, and then click Bring Online.
  8. Refresh the cluster node and confirm that all non-Cluster Shared Volume disks are online.
  9. In the Failover Cluster Manager, perform the following substeps for each Cluster Shared Volume:
    1. Record its name.
    2. Remove it.
  10. For each Cluster Shared Volume disk, perform the following substeps:
    1. Select the disk, and then click More Actions > Repair, replacing the disk.
    2. Perform a file-system restore for each Cluster Shared Volume, using the name recorded in step 9.
    3. Select the disk, and then click Bring Online.
  11. Refresh the cluster node and confirm that all Cluster Shared Volume disks are online.

Next steps

Use normal File System agent backups to restore file system data, noncritical disks, and critical disks on shared storage. Also, use application-agent backups to restore application data.
