You can create an aggregate or a Flash Pool aggregate to provide storage for one or more volumes by using System Manager.
You must have enough spare disks to create an aggregate.
You can initially create an aggregate with disks of the same size and add disks of a different size later.
You can initially create an aggregate with a single checksum type and add storage of a different checksum type later.
You can only manage aggregates (view aggregates, change the status, perform volume move for FlexVol volumes, and delete aggregates) in a MetroCluster configuration.
You can only manage SyncMirror aggregates (view aggregates, take the aggregate offline or make it online, and delete aggregates).
