HP-UX check SCSI reservation

Hi guys,

I need some help to better understand how to determine if a disk have persistent SCSI reservation. I know that we should use the "Persisten Reservation Utility" but we are not allowed to run that tool. Since we have the output from some grab utility and specifically we have the "scsimgr get _attr" I want to know how can i determine if there is any reservation on the disks.

Thanks for your help!
