Verify from the vxfenadm output that the SCSI-3 disk policy reflects the configuration in the /etc/vxfenmode file.
To verify I/O fencing configuration
# vxfenadm -d
Output similar to the following appears if the fencing mode is SCSI3 and the SCSI3 disk policy is dmp:
I/O Fencing Cluster Information: ================================ Fencing Protocol Version: 201 Fencing Mode: SCSI3 Fencing SCSI3 Disk Policy: dmp Cluster Members: * 0 (galaxy) 1 (nebula) RFSM State Information: node 0 in state 8 (running) node 1 in state 8 (running)
Verify that the disk-based I/O fencing is using the specified disks.
# vxfenconfig -l
