Display storage failover status

Availability: This command is available to cluster administrators at the admin privilege level.

Description

The storage failover show command displays information about storage-failover configurations. By default, the command displays the following information:

  • Node name.

  • Partner node name.

[-ha-type {none|shared_storage|non_shared_storage}] - HA Type

If this parameter is specified, the command selects the nodes that have the specified HA-type setting. If the value is set to shared_storage , then the node is in a storage-failover configuration using the shared storage. If it is set to non_shared_storage , then the node is in a storage-failover configuration using the unshared storage. If it is set to none , then the node is not part of a storage-failover configuration.

Examples

The following example displays information about all storage-failover configurations:
