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

See "Creating a volume on specific disks" on page 253.

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:

# vxplex -g mydg dis vol01-02

# vxedit -g mydg -r rm vol01-02
