After re-installation of RHEV the LUN is not visible in the RHEVM GUI

After doing a fresh installation of RHEV and trying to configure iSCSI storage, the LUN is not visible in the RHEVM GUI. I think because the LUN was used by a previous installation of RHEV it causes the LUN to not show up in the GUI.

This happens on the configuration screen for adding a new storage domain. Once you enter the address of the target (a NetAPP Filer) and click discover, no LUNs show as available, but if I run iscsiadm on the hypervisor I can see the LUN.

I was able to work around this issue by dding the LUN from the hypervisor, logging out of the targets, then add the storage again from the GUI.

Is this a bug? Or intended behaviour?

It would be better if the GUI did show the LUN but gave a warning and allowed you to wipe it or just use it anyway.

Cheers,
