Created attachment 1040767 [details] TUI reinstallation screenshot Description of problem: Reinstall rhevh7.1 by the command line in the grub in multipath iSCSI environment which has been installed rhevh6.7. After boot to the rhevh7.1 installation TUI, the TUI display should not be "<Upgrade 6.7-20150609.0.el6ev to 7.1-20150512.1.el7ev>", because we don't support upgrade from rhevh6.7 to rhevh7.1. Version-Release number of selected component (if applicable): rhev-hypervisor6-6.7-20150609.0.iso rhev-hypervisor7-7.1-20150512.1.iso How reproducible: 100% Steps to Reproduce: 1. PXE install rhev-hypervisor6-6.7-20150609 on the test machine with multipath iSCSI environment. 2. Configure the network then reboot the test machine. 3. PXE install rhev-hypervisor7-7.1-20150512.1.iso with reinstall parameter in cmdline to start up TUI installation. #cat /proc/cmdline initrd=/images/rhevh-vdsm7-7.1-20150512.1.el7ev.noarch/initrd0.img ksdevice=bootif rootflags=loop rootflags=ro rd.dm=0 rd_NO_MULTIPATH rd.md=0 crashkernel=256M rootfstype=auto lang= max_loop=256 rhgb quiet elevator=deadline rd.live.check rd.luks=0 install ro root=live:/rhevh-7.1-20150512.1.el7ev.iso rd.live.image BOOTIF=01-00-1f-29-03-86-7f reinstall BOOT_IMAGE=/images/rhevh-vdsm7-7.1-20150512.1.el7ev.noarch/vmlinuz0 Actual results: The TUI show <Upgrade 6.7-20150609.0.el6ev to 7.1-20150512.1.el7ev>. Expected results: The TUI should show <Install Hypervisor 7.1-20150512.1.el7ev>, should not show "Upgrade", because major version upgrade is not supported. Additional info:
This bug probably occurs because of bug 1233186 or bug 1051742. In both cases we fail to erase the previous RHEV-H from disk, and thus it looks like an upgrade to the TUI. Besides that we can probably enhance the TUI to catch this case.
