ONTAP 9.12.1 commands(CA08871-263en.pdf)

storage failover show

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.
Whether storage failover is possible.
The current state of storage failover. If the takeover is disabled the appropriate reason would be displayed.

To display detailed information about storage failover on a specific node, run the command with the -node parameter. The detailed view adds the following information:

You can specify additional parameters to select the displayed information. For example, to display information only about storage-failover configurations whose interconnect is down, run the command with` -interconnect-up false` .
