There were some patches in 3.5 related to that area.
Is the RHEV-M environment still connected to the LUNs? I may also need access to the system if you can leave it up. We get this information directly from udev, and I don't have a local hardware iscsi environment to test with. I see an error further down the logs indicating that there's still an LV present and it should be cleaned manually. Is this the failure to install you mean? That may also still be the data domain on the LUNs, but I'd have to be on a running system to see...
Chen, Could you help to answer Ryan's comment 3? Thanks.

Instead of a sleep, we can use udevadm settle to wait for teh current udev run to complete.
(In reply to Fabian Deutsch from comment #20) > Instead of a sleep, we can use udevadm settle to wait for teh current udev > run to complete. I'm somewhat worried that settling won't help, since the device didn't even register until after pre-pivot, but it's certainly worth trying
In some flows the details on the TUI page are not complete, i.e the vendor is missing. As this has no functional impact I'm moving this out to 3.6.
Test version: rhev-hypervisor7-7.2-20151112.1 ovirt-node-3.6.0-0.20.20151103git3d3779a.el7ev.noarch Test steps: 1. Install rhev-hypervisor7.2 on iscsi machine 2. Register to RHEVM and connect iscsi storage. 3. Reinstall rhev-hypervisor7.2 4. Focus on select disk page. 5. Try to finish the installation process Test result: Hypervisor can list the detail info of iscsi lun on select disk page even if the host has connected to iscsi storage before. So the bug is fixed, change bug status to VERIFIED.
