What is engine-ng? sorry, I mixed it up. It is ovirt node-ng.
version. I can detect and login to the iSCSI targets, but I cannot see any LUNs (on the LUNs > Targets page). That happens with our storage and with a linux based iSCSI target which I created for testing purposes.
Linux based iscsi based target works fine, we use it a lot for testing environment.
Can you share the output of these commands on the the host connected to the storage server?

When I logon to the ovirt hosts I see that they are connected with the target LUNs (dmesg is telling that there are iscsi devices being found and they are getting assigned to devices in /dev/sdX ). Writing and reading from the devices (also accros hosts) works. Do you have some advice how to troubleshoot this?
