I've configured a libvirt storage pool using an iscsi target from a Sun
7310 storage appliance and am using the LUNs in this target as volumes
for my KVM guests. The setup is very similar to what Daniel covered in
a recent blog posting:
http://berrange.com/posts/2010/05/05/provisioning-kvm-virtual-machines-on-iscsi-the-hard-way-part-2-of-2/
It works great, but I can't figure out how to match the volume names &
path IQNs within the storage pool to the GUIDs on the target.
For example, here's what I see when I use the vol-info command:
# virsh vol-list kvm-target
Name Path
-----------------------------------------
6.0.0.0
/dev/disk/by-path/ip-X.X.X.X:3260-iscsi-iqn.1986-03.com.sun:02:<snipped>-lun-0
6.0.0.1
/dev/disk/by-path/ip-X.X.X.X:3260-iscsi-iqn.1986-03.com.sun:02:<snipped>-lun-1
The IQN matches the targets IQN, but when I browse the LUNs from the
storage system I do not see a way to determine which of them is *-lun-0
and which is *-lun-1, I only see a GUID and an alias name that I created.
Is there any way to get that info (or something else that will do the
job) from a virsh command?
Thanks in advance for any help.
Tom
