servers (blades) that have no FC connectivity

oh, now i see
my mistake was putting storage domain in maintenance - when it in
maintenance, all options is greyed out, but when active - discover&login
options awailable.
Thanks for help!

but you can add a iscsi disk to a existing iscsi domain ... see attached
screenshot .. .if the disk you're adding has the same LUN ID as the already
existing one, ovirt will just "add it" as a 2nd / 3rd / 4th and so forth
path ...

In ovirt webadmin i cannot edit added domain - connection information is
greyed out (even when storage domain in maintenance mode)

I think i'd just add the 2nd path when the device is available ... i've
recently exprimented with iscsi / tgtd and multipath on a ovirt hyper-visor
and it will identify the disk as "the same" (new path to target) as long as
the LUN ID is the same (this is taken from experience, not from a spec

serv1/serv2 - connectivity isnt a pro

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
