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.
Alternatively, use the following command to dissociate and remove a mirror from a volume:
# vxplex [-g
diskgroup] -o rm dis
plex
For example, to dissociate and remove a mirror named vol01-02
from the disk group, mydg
, use the following command:
# vxplex -g mydg -o rm dis vol01-02
This command removes the mirror vol01-02
and all associated subdisks. This is equivalent to entering the following separate commands:
# vxedit -g mydg -r rm vol01-02
