Mirroring the root aggregates

You must mirror the root aggregates to provide data protection.

About this task

By default, the root aggregate is created as RAID-DP type aggregate. You can change the root aggregate from RAID-DP to RAID4 type aggregate. The following command modifies the root aggregate for RAID4 type aggregate:

storage aggregate modify –aggregate aggr_name -raidtype raid4
Note
On non-ADP systems, the RAID type of the aggregate can be modified from the default RAID-DP to RAID4 before or after the aggregate is mirrored.
  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.
  2. Repeat the previous step for each node in the MetroCluster configuration.
