cluster::> metrocluster check node show –instance
                            Node Name: siteA-01
                        Type of Check: ha-mirroring-op-state
                         Cluster Name: cluster_name
                  Result of the Check: warning
Additional Information/Recovery Steps: Node's HA mirroring is not online. Verify the HA mirroring link status with the "metrocluster interconnect show" command, then bring the HA mirroring online with the "storage failover modify -node <node> -enabled true" command.
                            Node Name: siteA-02

                         Cluster Name: cluster_name
                  Result of the Check: warning
Additional Information/Recovery Steps: Node's DR mirroring is not online. Check the RDMA connectivity to its DR partner, run the "metrocluster node show" command to verify the node and its DR partner are up and normal, then bring the DR mirroring online with the (privilege: diag) "metrocluster interconnect mirror modify -node <node> -partner-type DR -mirror-oper-status online" command.
