Disaster Recovery on NEC CLUSTERPRO/ExpressCluster SE

Several types of failures can occur in a cluster environment. The following types of failure can happen separately or at the same time:

• Shared disk fails
• Some cluster nodes fail (primary node failure and secondary node failure)
• Entire cluster fails, including cluster nodes and shared disks

This section provides the procedures to follow to recover from various types of cluster failure.

Note: If the cluster node is not a backup server (no tape device is attached to the cluster node), follow the instructions for performing a remote disaster recovery.
