how to display vxfen keys on unix

hi,

for a VCS cluster which is configured with CPS I/O fencing, how can i display the vxfencing keys? i would like to verify that a disk is locked by vxfencing for a particular vcs node.

The Diskgroup resource is online btw, UseFence =SCSI3 and /var/VRTSvcs/log/vxfen/* doesn't particularly complain about anything.

thanks,

ida
