VxVM vxplex ERROR V-5-1-809 Plex plex in volume volume is locked by another utility.

VxVM vxplex ERROR V-5-1-809 Plex -02 in volume is locked by another utility 

The vxplex command fails because a previous operation to attach a plex did not complete. The vxprint command should show that one or both of the temporary and persistent utility fields (TUTIL0 and PUTIL0) of the volume and one of its plexes are set.

If the vxtask list command does not show a task running for the volume, use the vxmend command to clear the TUTIL0 and PUTIL0 fields for the volume and all its components for which these fields are set:

# vxmend -g diskgroup clear all volume plex ...

# vxplex [-g diskgroup] det plex

# vxplex [-g diskgroup] att volume plex

Alternative, by clearing the tutil0 for both the volume and plex will release the lock hold by "another utility".

# vxedit [-g diskgroup] -f set tutil0="" volume

# vxedit [-g diskgroup] -f set tutil0="" plex

then you can detect/attach the plex.
