You can remove a plex from a mirrored aggregate. You might do this if you want to stop mirroring the aggregate, or if there is a problem with the plex. Removing a plex results in an unmirrored aggregate.
About this task
In case of a failure that causes a plex to fail, you can remove the plex from the mirrored aggregate, fix the problem, and then re-create it. You can also re-create it using a different set of disks or array LUNs, if the problem cannot be fixed.
- Take the selected plex offline by entering the following command:aggr offline plex-name
is the name of one of the mirrored plexes.
Note: Only one plex at a time can be taken offline.
- Destroy the plex you took offline by entering the following command:aggr destroy plex-name
Removing and destroying a plex from a mirrored aggregate results in an unmirrored aggregate, because the aggregate now has only one plex.
After removing the plex, Data ONTAP converts the disks or array LUNs used by the plex into hot spares.
