Mirroring the root aggregates
You must mirror the root aggregates in your MetroCluster configuration to ensure data protection.
You must have ensured that the SyncMirror requirements for the MetroCluster configuration with array LUNs are satisfied. Refer to Requirements for a MetroCluster configuration with array LUNs.
You must repeat this task for each controller in the MetroCluster configuration.
Mirror the unmirrored root aggregate:
storage aggregate mirror
The following command mirrors the root aggregate for controller_A_1:
controller_A_1::> storage aggregate mirror aggr0_controller_A_1
The root aggregate is mirrored with array LUNs from pool1.
