oVirt nodes are iSCSI clients and each node needs to have a different
InitiatorName value.
Eventually you can modify initiatorname of a node before running discovery
against oVirt and rebooting it (or restarting iscsi services).
You can edit the file or use the iscsi-iname command.
It must be named with an iqn name in the format of
iqn.-MM.reverse.domain.name:OptionalIdentifier
Typically you configure your iSCSI storage array giving access to the lun
to be used as a storage domain to all oVirt hosts initiators. Or you can
use chap authentication or both

You have to add all the initiators for each node to the iscsi LUN.  At
least thats how I got it working.  Then I think it's recommended to setup
multipath.

However take this with a grain because iscsi did not work well for me.
