Removing a Mirror
When a mirror is no longer needed, you can remove it to free up disk space.
Note The last valid plex associated with a volume cannot be removed.
To remove a mirror from a volume, use the following command:
# vxassist [-g diskgroup] remove mirror volume
Additionally, you can use storage attributes to specify the storage to be removed. For
example, to remove a mirror on disk mydg01 from volume vol01, enter:
# vxassist -g mydg remove mirror vol01 !mydg01
For more information about storage attributes, see “Creating a Volume on Specific Disks”
on page 203.
Alternatively, use the following command to dissociate and remove a mirror from a
volume:
# vxplex [-g diskgroup] -o rm dis plex
