If the cluster consists of more than one node, you should verify that each node can successfully fail over to another node. This helps ensure that the system is configured correctly and that you can maintain access to data if a real failure occurs.
Before you begin
The cluster must consist of more than one node.
About this task
You should test storage failover on one HA pair
at a time. To simplify troubleshooting if needed, do not try to fail over more than one node at a time.
For more information about storage failover, see the Clustered Data ONTAP High-Availability Configuration Guide.
- Check the failover status by entering the following command:
storage failover show
- Take over the node by its partner using the following command:
storage failover takeover -ofnode nodename
storage failover takeover -ofnode cluster1-02
- Verify that failover was completed by using the storage failover show command.
- Give back the storage to the original node by using the following command:
storage failover giveback
storage failover giveback -ofnode cluster1-02
- Verify that giveback was completed by using the storage failover show-giveback command.
- Revert all LIFs back to their home nodes by entering the following command:
network interface revert *
- Repeat these steps for each remaining node in the cluster.
