Cluster Failure Scenarios

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

• Some cluster nodes fail (primary node failure and secondary node failure)
• Shared disk fails (cluster non-quorum disk failure)
• Partial shared disk fails
• Entire cluster fails including cluster nodes and shared disks

The scenarios specified in this section outline the steps you can take to recover from various types of cluster failure.

Note: If no tape device is attached to any of the cluster nodes, you can remotely recover a cluster service using the option. To do so, follow the instructions on performing a remote disaster recovery.
