Clearing keys after split brain using vxfenclearpre command

When you have encountered a split brain condition, use the vxfenclearpre command to remove SCSI-3 registrations and reservations on the coordinator disks as well as on the data disks in all shared disk groups.

 To clear keys after split brain

1. Shut down all other nodes in the cluster that have access to the shared storage. This prevents data corruption.
2. Start the script:

   # cd /opt/VRTSvcs/vxfen/bin

   # ./vxfenclearpre

3. Read the script's introduction and warning. Then, you can choose to let the script run.

   Do you still want to continue: [y/n] (default : n) y
