Removing and destroying a plex

Why you might remove and destroy a plex

You might remove a plex from a mirrored aggregate or traditional volume and destroy it if there was a problem with that plex. For example, if you have a double-disk failure that causes a plex to fail, you can remove the plex from the mirrored aggregate or traditional volume, fix the problem, and then recreate it, or you can recreate it using a different set of disks if the problem cannot be fixed.

You might also remove a plex from a mirrored aggregate or traditional volume and destroy it if you want to stop mirroring the aggregate or traditional volume.

Destroying a plex from a mirrored aggregate

Step	Action
1	Take offline all of the FlexVol volumes in the plexes you decided to take offline by entering the following command: vol offline vol-name vol-name is the name of the FlexVol volume. Note Only one FlexVol volume at a time can be taken offline.
2	Remove the FlexVol volumes from the plexes you decided to take offline by entering the following command: vol destroy vol-name vol-name is the name of the FlexVol volume. Note Only one FlexVol volume at a time can be taken offline.
3	Take offline all of the plexes you decided to take offline by entering the following command: aggr offline plex-name plex-name is the name of one of the mirrored plexes. Note Only one plex at a time can be taken offline.
4	Destroy the plex you took offline by entering the following command: aggr destroy plex-name plex-name is the name of one of the mirrored plexes.

Result of removing and destroying a plex

Removing and destroying a plex from a mirrored aggregate or traditional volume results in an unmirrored aggregate or traditional volume, because the aggregate or traditional volume now has only one plex.

After removing the plex, Data ONTAP converts the good disks used by the plex into hot spare disks.
