Verifying a successful switchback

You want to confirm that all aggregates and SVMs are switched back and online.

Steps

  1. Switched over data aggregates (in the following example, aggr_b2 on node B2) are switched back: aggr show
    Example
    controller_B_1::> aggr show
    Aggregate     Size Available Used% State   #Vols  Nodes            RAID Status
    --------- -------- --------- ----- ------- ------ ---------------- ------------
    ...
    aggr_b2    227.1GB   227.1GB    0% online       0 controller_B_2   raid_dp,
                                                                       mirrored,
                                                                       normal
    
    controller_B_1::> aggr show
    Aggregate     Size Available Used% State   #Vols  Nodes            RAID Status
    --------- -------- --------- ----- ------- ------ ---------------- ------------
    ...
    aggr_b2          -         -     - unknown      - controller_A_1        
  2. All sync-destination SVMs on the surviving cluster are dormant (showing an Admin State of stopped) and the sync-source SVMs on the disaster cluster are up and running. vserver show -subtype sync-source
    Example
    controller_B_1::> vserver show -subtype sync-source
                                   Admin      Root                       Name    Name
    Vserver     Type    Subtype    State      Volume     Aggregate       Service Mapping
    ----------- ------- ---------- ---------- ---------- ----------      ------- -------
    ...
    vs1a-mc        data    sync-source
                                   running    vs1a_vol   controller_B_2  file    file
                                                                   aggr_b2
                                                     
    controller_A_1::> vserver show -subtype sync-destination 
                                   Admin      Root                  Name    Name
    Vserver     Type    Subtype    State      Volume     Aggregate  Service Mapping
    ----------- ------- ---------- ---------- ---------- ---------- ------- -------
    ...
    mcc1A-vs1a-mc  data    sync-destination
                                   stopped    vs1a_vol   sosb_      file    file
                                                        aggr_b2
    
  3. Confirm that the switchback operations succeeded by using the metrocluster operation show command.
    If the command output shows... Then...
    That the switchback operation state is successful. The switchback process is complete and you can proceed with operation of the system.
    That the switchback operation or switchback-continuation-agent operation is partially successful. Perform the suggested fix provided in the output of the metrocluster operation show command.
