That's odd. gamma is my iscsi host, its in up state and it has active VM's. What am I missing?

Ok I got the uuid but I am getting the same results as before. Nothing comes up.
[root@gamma ~]# pvscan --cache [root@gamma ~]# lvs -o vg_name,lv_name,tags | grep 3b7d9349-9eb1-42f8-9e04-7bbb97c02b98 [root@gamma ~]#
without the grep all I get is:
[root@gamma ~]# lvs -o vg_name,lv_name,tags VG LV LV Tags vg_gamma lv_home vg_gamma lv_root vg_gamma lv_swap
You are not connected to the iscsi storage domain.
Please try this from a host in up state in engine.

On the other hand an fdisk shows a bunch of disks and here is one example:

The image-uuid of the template is displayed in the Disks tab in engine.
To find the volume-uuid on block storage, you can do:
pvscan --cache lvs -o vg_name,lv_name,tags | grep image-uuid
