Is there a way to guess which block devices / disk does Xen use at the moment?

I use Xen with iSCSI.
I connect to 50 iSCSI targets or more on each Xen server - and I get "virtual disks" ranging from /dev/sda to /dev/sdbl etc. - it's a lot.

Sometimes, I want to log out a given iSCSI connection (parameters changed on a target etc.) - but before I actually do it, I would like to know if that iSCSI drive is not used by Xen.

In other word - is there a way to check if Xen uses block device /dev/sda, /dev/sdu or /dev/sdbb etc.?

Well, what does "mount" say from the DomU, and what does "xm list [DOMAIN] --long" say on the Dom0?
