Hi all I am working with Oracle Linux Virtualization Manager 4 (OLVM) which is based on ovirt. When I worked with OLVM 3 and when assigning direct lun to the guests in the guest I could obtain LUN's wwid with this command /usr/lib/udev/scsi_id -g -u -d /dev/sdc1 36000c29f1382ae964d67392dfdfaaf0f similar to VMWare's disk.EnableUUID But now in OLVM 4 I am getting this in the guest which is not LUN's wwid /usr/lib/udev/scsi_id -g -u -d /dev/sdc 0QEMU_QEMU_HARDDISK_671b475e-98ab-4f3b-a23d-2f8eed964e92 I wonder if is it possible to get LUN's wwid in the guest in OLVM 4? Thanks1
