Is my XIV device open?

Hi there,

I am trying to determine if a specific XIV LUN on AIX is in OPEN or CLOSED state. I would like tthe same info as I can get from
Code:
pcmpath

command on v7000 LUN-s. I would need this info to find out if I can safely delete a LUN or not.

I tried fuser command, but no luck. It did not show anything fo PV-s that azre part of varyed-on VG-s.

Also tries
Code:
xiv_devlist -o multipath

but it tells every path OK even if they are in use or not. (failed/missing can be found, but that's not what I am looking for)

After a log of google searches I have no more ideas today. Anybody else?

SG_EMC_TRESPASS(8)						     SG3_UTILS							SG_EMC_TRESPASS(8)

NAME
sg_emc_trespass - Changes ownership of a LUN from another Service-Processor to this one. SYNOPSIS
sg_emc_trespass [-d] [-hr] [-s] [-V] DEVICE DESCRIPTION
sg_emc_trespass sends an EMC-specific Trespass Command to the DEVICE with the selected options. This Mode Select changes the ownership of the LUN of the device from another Service-Processor to the one the command was received on. OPTIONS
Arguments to long options are mandatory for short options as well. -d outputs some extra debug information associated with executing this command -hr Sets the 'Honor Reservation' bit in the command. If set, the trespass will only succeed to change the ownership from the Peer SP if the Peer SP does not have an outstanding SCSI reservation for the LUN. By default, the reservation state will be ignored. -s Send the short version of the trespass command instead of the long version. The short version is supported on the EMC FC5300, FC4500 and FC4700. The long version (default) is supported on the CLARiiON CX and AX family arrays. -V print out version string then exit. In the 2.4 series of Linux kernels the DEVICE must be a SCSI generic (sg) device. In the 2.6 series block devices (e.g. SCSI disks and DVD drives) can also be specified. For example "sg_start 0 /dev/sda" will work in the 2.6 series kernels. EXIT STATUS
The exit status of sg_emc_trespass is 0 when it is successful. Otherwise see the sg3_utils(8) man page. AUTHOR
