Verifying local HA operation

You should verify the operation of the local HA pairs in the MetroCluster configuration.

1. On cluster_A, perform a failover and giveback in both directions.
   1. Confirm that storage failover is enabled: storage failover show
      Example
      The output should indicate that takeover is possible for both nodes:

      cluster_A::> storage failover show
                                    Takeover
      Node           Partner        Possible State Description
      -------------- -------------- -------- ---------------------------
      controller_A_1 controller_A_2 true     Connected to controller_A_2
      
      controller_A_2 controller_A_1 true     Connected to controller_A_1
      2 entries were displayed.
      
      

   2. Takeover controller_A_2 from controller_A_1: storage failover takeover controller_A_2
      You can use the storage failover show-takeover command to monitor the progress of the takeover operation.
   3. Confirm that the takeover is complete: storage failover show
      Example
      The output should indicate that controller_A_1 is in takeover state, meaning that it has taken over its HA partner:

      cluster_A::> storage failover show
                                    Takeover
      Node           Partner        Possible State Description
      -------------- -------------- -------- -----------------
      controller_A_1 controller_A_2 false    In takeover
      
      controller_A_2 controller_A_1 -        Unknown
      2 entries were displayed.
      
      

   4. Give back controller_A_2: storage failover giveback controller_A_2
      You can use the storage failover show-giveback command to monitor the progress of the giveback operation.
   5. Confirm that storage failover has returned to a normal state: storage failover show
      Example
      The output should indicate that takeover is possible for both nodes:

      cluster_A::> storage failover show
                                    Takeover
      Node           Partner        Possible State Description
      -------------- -------------- -------- ---------------------------
      controller_A_1 controller_A_2 true     Connected to controller_A_2
      
      controller_A_2 controller_A_1 true     Connected to controller_A_1
      2 entries were displayed.
      
      

   6. Repeat the previous substeps, this time taking over controller_A_1 from controller_A_2.
2. Repeat the previous step on cluster_B.
