Enabling storage failover on both controller modules and enabling cluster HA
After adding new controller modules to the MetroCluster configuration, you must enable storage failover on both controller modules and separately enable cluster HA.
The MetroCluster configuration must have previously been refreshed using the metrocluster configure -refresh true
command.
This task must be performed on each MetroCluster site.
-
Enable storage failover:
storage failover modify -enabled true -node existing-node-name
The single command enables storage failover on both controller modules.
-
Verify that storage failover is enabled:
storage failover show
The output should be similar to the following:
Node Partner Possible State Description -------------- -------------- -------- ---------------------- old-ctlr new-ctlr true Connected to new-ctlr new-ctlr old-ctlr true Connected to old-ctlr 2 entries were displayed.
-
Enable cluster HA:
cluster ha modify -configured true
Cluster high availability (HA) must be configured in a cluster if it contains only two nodes and it differs from the HA provided by storage failover.
