[ovirt-users] unable to create iSCSI storage domain

Hi, I've a problem creating an iSCSI storage domain. My hosts are running the current ovirt 4.2 engine-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. 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? Regards Bernhard
