Hello!

I was just trying to setup my first oVirt Server via Cockpit but it failed when I wanted to connect it to my iSCSI.

These are the last lines of my vdsm.log:

As you can see it finds the targets but for some reason it fails. The initiator name should be configured correctly.

I really don't know what the problem is and I haven't found an answer anywhere on the internet.
I hope you can help me out.

Yes, sorry, this is a bug and it's tracked here: https://bugzilla.redhat.com/show_bug.cgi?id=1672542

It will be fixed by https://github.com/oVirt/ovirt-ansible-hosted-engine-setup/pull/109/commits/ceca0a852d94bd5af7226b15d15c9e3ff917cd5c

Since the fix is really simply I'd suggest to manually apply it editing
/usr/share/ansible/roles/ovirt.hosted_engine_setup/tasks/iscsi_discover.yml
and
/usr/share/ansible/roles/ovirt.hosted_engine_setup/tasks/iscsi_getdevices.yml
and removing 'no_log: true' lines before trying again from cockpit.

If you instead already know the IQN of your target and the WWID of the LUN you want to use another option is to directly enter them in cockpit.
