You can convert an existing aggregate to a mirrored aggregate to protect the data on the aggregate. You convert the aggregate to a mirrored aggregate by adding a plex to the aggregate.
This method is best suited for when you know the disks or array LUNs to be used for the plex addition and want to specify those disks or array LUNs manually.
This is the easiest method of adding a plex to an aggregate. If the aggregate that you want to mirror uses disks or array LUNs of different capacities, Data ONTAP can select disks or array LUNs that match the smallest capacity from a different pool. If there are not enough disks or array LUNs of that capacity in the pool, Data ONTAP selects higher-capacity disks or array LUNs and downsizes them.

This step adds a plex to the aggregate, making it a mirrored aggregate.
