Removing and destroying a plex from a mirrored volume

Why you might remove and destroy a plex

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

Result of removing and destroying a plex

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

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