[Users] way to edit iSCSI storage domain?

Hi, is there any way to edit iSCSI storage domain: change/add targets ? (lun, id, sn and actual content wouldn't be affected) Without VM export/import process - downtime should be as little as possible. I'm researching possibility to use oVirt in env where I have only FC storage, connected to 2 servers (and sadly, second server will be available later, hence my question about changing targets in oVirt) and bunch of blades, on which i would like to run virtualization (no fc storage connectivity) - so idea is to share storage via iSCSI/tgtd and use multipathd with failover mode to protect from storage corruption. -- Yuriy Demchenko
