Healing the root aggregates after a disaster

After the data aggregates have been healed, you must heal the root aggregates in preparation for the switchback operation.

1. Switch back the mirrored aggregates by running the metrocluster heal -phase root-aggregates command.

   Example

   mcc1A::> metrocluster heal -phase root-aggregates
   [Job 137] Job succeeded: Heal Root Aggregates is successful
   
   

   If the healing is vetoed, you have the option of reissuing the metrocluster heal command with the –override-vetoes parameter. If you use this optional parameter, the system overrides any soft vetoes that prevent the healing operation.

2. Ensure that the heal operation is complete by running the metrocluster operation show command on the destination cluster:

   Example

   mcc1A::> metrocluster operation show
     Operation: heal-root-aggregates
         State: successful
    Start Time: 7/29/2014 20:54:41
      End Time: 7/29/2014 20:54:42
        Errors: -
   
   
   
3. Power up each controller module on the disaster site.
4. After nodes are booted, verify that the root aggregates are mirrored.

   If both plexes are present, any resynchronization will start automatically. If one plex has failed, that plex must be destroyed and the mirror recreated using the storage aggregate mirror -aggregate aggregate-name command to reestablish the mirror relationship.
