Volume Tasks
Removing a Mirror From a Volume
Chapter 4184
When you have provided all necessary information in the dialog box,
click OK.
Notes:
This task requires a volume name. This task also requires the
number of mirrors to remove, a disk name, or a mirror name.
If a volume only has two mirrors and one mirror is removed, the
volume is no longer redundant.
The last mirror (plex) cannot be removed from a volume.
When a mirror is removed, the space occupied by that mirror is
returned to the free space pool.
