Description:
=========
Starting a volume reports the error above. The vxprint output shows that the plexes for the volume are in "DISABLED RECOVER" state.


Solution:
=======
The following commands must be run on a plex to change the state of the plex to "CLEAN". The volume can then be started,  but a fsck may be required before mounting the file system.

# vxmend -o force off
# vxmend on
# vxmend fix clean
# vxvol start
# fsck -F vxfs/dev/vx/rdsk//
# mount -F vxfs /dev/vx/dsk///mountpoint


Here is an example:
The diskgroup dg01 has 2 volumes, apps and home. Trying to start all the volumes reported the following error:

# vxvol -g dg01startall
vxvm:vxvol: ERROR: Volumehome has no CLEAN or non-volatile ACTIVEplexes

# vxprint -g dg01-th     <== Showed thefollowing

The following commands need to be run on one of the plexes before trying to start the volume'home':
 

The volume will then start successfully using the cleaned plex (the second plex, 'home-02' will automatically resync using plex'home-01'):

# vxvol starthome

Note:
It may be necessary to run fsck on the file system before mounting it:

# fsck -F vxfs/dev/vx/rdsk//
#mount -F vxfs /dev/vx/dsk///mountpoint
