You convert a mirrored aggregate to an (unmirrored) aggregate by removing a plex. You might do this if you want to stop mirroring the aggregate, or if there is a problem with the plex.
- Take the selected plex offline by using the storage aggregate plex offline command.
- Destroy the plex you took offline by using the storage aggregate plex delete command.
After destroying the plex, Data ONTAP converts the disks or array LUNs used by the plex into hot spares.
