If all mirrors of a volume become
STALE, you can place the volume in maintenance mode. Then you can view the plexes while the volume is
DETACHED and determine which plex to use for reviving the others. To place a volume in maintenance mode, use the following command:
vxvol [-g diskgroup
To assist in choosing the revival source plex, use
vxprint to list the stopped volume and its plexes.
To take a plex (in this example,
vol01-02 in the disk group,
mydg) offline, use the following command:
vxmend -g mydg off vol01-02
on command can change the state of an
OFFLINE plex of a
DISABLED volume to
STALE. For example, to put a plex named
vol01-02 in the STALE state, use the following command:
vxmend -g mydg on vol01-02
start command on the volume then revives the plex.
