Hi Naseer,
You can use both Navicli and Navisphere to check the trespass lun status.
If you have EMC PowerPath, you will see "emcp" messages logged to /var/adm/syslog/syslog.log by powerpath driver. The search word is "trespass".
You can use "powermt display dev=all" and check for current and default owner for the individual LUN.
If you do not have PowerPath, then check for any messages "powerfailed" on /var/adm/syslog/syslog.log.
Hope it helps.
