To test disks using the vxfentsthdw script

1. Make sure system-to-system communication is functioning properly.
2. From one node, start the utility.

   # vxfentsthdw [-n]

3. After reviewing the overview and warning that the tests overwrite data on the disks, confirm to continue the process and enter the node names.

   ******** WARNING!!!!!!!! ********
   THIS UTILITY WILL DESTROY THE DATA ON THE DISK!!
   
   Do you still want to continue : [y/n] (default: n) y
   Enter the first node of the cluster: sys1
   Enter the second node of the cluster: sys2
   

4. Enter the names of the disks you are checking. For each node, the disk may be known by the same name:

   Enter the disk name to be checked for SCSI-3 PGR on node 
   sys1 in the format: 
           for dmp: /dev/vx/rdmp/sdx
           for raw: /dev/sdx
   Make sure it's the same disk as seen by nodes sys1 and sys2
   /dev/sdr
   
   Enter the disk name to be checked for SCSI-3 PGR on node 
   sys2 in the format: 
           for dmp: /dev/vx/rdmp/sdx
           for raw: /dev/sdx
   Make sure it's the same disk as seen by nodes sys1 and sys2
   /dev/sdr

   If the serial numbers of the disks are not identical, then the test terminates.

5. Review the output as the utility performs the checks and report its activities.
6. If a disk is ready for I/O fencing on each node, the utility reports success:

   ALL tests on the disk /dev/sdx have PASSED
   The disk is now ready to be configured for I/O Fencing on node 
   sys1
   ...
   Removing test keys and temporary files, if any ...
   .
   .

7. Run the vxfentsthdw utility for each disk you intend to verify.
