Reestablishing the MetroCluster configuration

You can reestablish a MetroCluster configuration after a disaster, depending on the state of the mirrored aggregate at the time of the takeover.

Depending on the state of a mirrored aggregate before you forced the surviving node to take over its partner, you use one of two procedures to reestablish the MetroCluster configuration:

  • If the mirrored aggregate was in a normal state before the forced takeover, you can rejoin the two aggregates to reestablish the MetroCluster configuration.

    This is the most typical case.

  • If the mirrored aggregate was in an initial resynchronization state (level-0) before the forced takeover, you cannot rejoin the two aggregates.

    You must re-create the synchronous mirror to reestablish the MetroCluster configuration.
