Previously, a successful kernel upgrade of a Red Hat Enterprise Virtualization Hypervisor node in UEFI mode updated the backup boot option in /grub/grub.conf instead of /EFI/redhat/grub.conf. Booting the backup option from the grub menu in UEFI mode failed as a result.
Now, the correct grub configuration is updated on upgrade, and the backup kernel boot option works as expected in UEFI mode.
Description of problem:
In fact, rhev-h used the /EFI/redhat/grub.conf in /dev/mapper/36782bcb03cdfa200174636ff055184dcp1 to boot rhev-h under uefi mode.
But when upgrade rhev-h via cmdline in uefi mode, rhev-h still saved the backup version in the /grub/grub.conf of /dev/mapper/36782bcb03cdfa200174636ff055184dcp3
So that when upgrade rhev-h via cmdline in uefi mode success, it couldn't find to the backup version to boot.
Also noticed that the grub title does not update to latest in the /EFI/redhat/grub.conf.
No this issue when upgrade rhev-h via tui/rhev-m in uefi mode
Version-Release number of selected component (if applicable):
rhev-hypervisor6-6.4-20121031.0.el6
How reproducible:
100%
Steps to Reproduce:
1.install the old rhev-h in uefi mode.
2.upgrade the rhev-h via cmdline in uefi mode.
Actual result:
After upgrade rhev-h from rhev-hypervisor6-6.4-20121031.0.el6 to rhev-hypervisor6-6.4-20121120.0.el6 via cmdline in uefi mode.
we only selected the new version to boot,the /EFI/redhat/grub.conf missed the backup version part

Expect result:
The /EFI/redhat/grub.conf could save the backup version part when upgrade rhev-h via cmdline in uefi mode
