Error Message
# /opt/VRTS/bin/vxfentsthdw
Veritas vxfentsthdw version 8.0.0.1500 Linux
The utility vxfentsthdw works on the two nodes of the cluster.
The utility verifies that the shared storage one intends to use is
configured to support I/O fencing. It issues a series of vxfenadm
commands to setup SCSI-3 registrations on the disk, verifies the
registrations on the disk, and removes the registrations from the disk.
******** WARNING!!!!!!!! ********
THIS UTILITY WILL DESTROY THE DATA ON THE DISK!!

Cause
The failure was due to dmp not handling an error correctly.
Resolution
The failure can be safely ignored. The code has been fixed in VxVM 7.4.2.3701 for rhel and will be included in the next VxVM 8.0 GA patch. The fix is also present in the forthcoming IS 8.0.2 Release.
