Before using mirrored aggregates or traditional volumes, you need a SyncMirror license, storage systems that support the SyncMirror feature, and an appropriate configuration of disk shelves.
The SyncMirror license is available for free.
For more information about configurations that support mirrored aggregates or traditional volumes, see the Data ONTAP Active/Active Configuration Guide.
For information about the disk shelves and other hardware supported with different storage systems, see the System Configuration Guide.
