To be honest, I just asked from curiosity.In NFS it's mandatory to use group 36, but this is the linux group.
I guess in TrueNAS it's something else, as I never configured group in targetcli.
The flow is usually:
- Target server listens on multiple IPs
- Client makes discovery on a single ip
- client logs in (lsscsi is the simplest approach to verify it)
- Client discovers and logs on other IPs that the target server uses
- Multipath aggregates the links
As Multipath has a timeout of 20s while iscsi client uses 120s by default, I usually change the client to use 15s timeout.
When a path (for eample 1 switch is dead) is down, multipath will try another link to reach the target server.
It's nice there is a vdsm tool to configure those .
WARNING: Never set clients with the same IQN (defined in a file in /etc/iscsi...somethig -> see with rpm -ql iscsi-utils)

I used group 1 because nothing said what group to use, and googling "ovirt iSCSI setup" returned nothing useful so I picked a number. If there is someplace that actually gives detailed instructions I'm going to bookmark it when I get the link.
Yes, there is a storage network. There was a miscommunication and the person attempting to create the connection didn't read instructions, so they keyed in the main network ip, leaving a small mess for me to clean up. The old truenas with nfs share is on the storage network and functioning cleanly, and ovirt is able to see the iSCSI share on the storage network ip address.
Thank you.
Did you configure a storage network on oVirt ?
About the size, why you use group '1' and not group '36' ?
