Hello  Yes.  There is a TRESPASS LUN STATUS report that you can run.  It will report all trespassed LUNS.  For Unisphere it is under MONITORING -> REPORTS -> Trespassed LUN Status.  I can't recall for NaviManager...(I beleive right click array and should be a drop down, or TOOLS -> Trespassed LUN Status
Is there a way on the clariion to find out which lun is trespassing - you only get the Bus-Enclosure -Disk numbers - which in turn can be mapped to a raid group.  The problem is that you can have multiple Luns being owned by multiple hosts within that raid group.  Is there a way the actually see what Lun is being trespassed?
