Mirroring the root aggregate on the new controller
Contributors Download PDF of this page
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.
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.
