Issue

While configuring a MetroCluster IP, the HA interconnect does not come online after booting the nodes and configuring the cluster.

ClusterA::> cluster ha show High Availability Configured: false Warning: Cluster HA has not been configured. Cluster HA must be configured on a two-node cluster to ensure data access availability in the event of storage failover. Use the "cluster ha modify -configured true" command to configure cluster HA. ClusterA::> storage failover show Takeover Node Partner Possible State Description -------------- -------------- -------- ------------------------------------- ClusterA-01 - false Waiting for partner, Takeover is not possible: Storage failover is disabled ClusterA-02 - false Waiting for partner, Takeover is not possible: Storage failover is disabled 2 entries were displayed.

During boot, the following messages might be seen:

mccip_install_dr_ips: bootarg.ic_local_ip not set, bailing iw_cxgbe: Chelsio T4/T5/T6 RDMA driver loaded [cluster_A-01:cf.fsm.takeoverOfPartnerDisabled:error]: Failover monitor: takeover of ClusterA-02 disabled (HA interconnect error. Verify that the partner node is running and that the HA interconnect cabling is correct, if applicable. For further assistance, contact technical support).

Interfaces will report as down:
