Checking SCSI3 Persistent Reservation Status of a LUN

The Veritas supplied SCSIcmd utility provides a useful way to confirm if a Symmetrix presented LUN has the SCSI3 Persistent Reservation attribute set. This is requirement for Windows Server Clustering. Use Emulex HBAnyware/OC Manager to identify the correct LUN Id (E.g. 9) to use with the -d switch.

> scsicmd -d9 -sscsi3_test

All tests should PASS.
