Mirroring the root aggregate on the new controller

Contributors netapp-thomi

You must mirror the root aggregate to provide data protection when you are adding a controller to a MetroCluster configuration.

This task must be performed on the new controller module.

  1. Mirror the root aggregate:

    storage aggregate mirror aggr_name

    The following command mirrors the root aggregate for controller_A_1:

    controller_A_1::> storage aggregate mirror aggr0_controller_A_1

    This mirrors the aggregate, so it consists of a local plex and a remote plex located at the remote MetroCluster site.
