Description Fabian Deutsch 2015-01-06 20:41:09 UTC

Description of problem:
With 6.6 we need to set the correct wwid on the kernel commandline during boot.
On fresh 6.6 installations this is done by the installer.

But the upgrade logic needs to be improved to cover the case where a user with a multipath disk is upgarding rhev-h.

Comment 1 Fabian Deutsch 2015-01-12 15:42:42 UTC

This scenario is already covered by the current implementation.

# cat /etc/system-release
Red Hat Enterprise Virtualization Hypervisor 6.6 (20150128.0.el6ev)
# rpm -q ovirt-node kernel
ovirt-node-3.2.1-6.el6.noarch
kernel-2.6.32-504.8.1.el6.x86_64

    kernel /vmlinuz0 root=live:LABEL=Root ro rootfstype=auto rootflags=ro ksdevice=bootif  max_loop=256 crashkernel=128M lang= rd_NO_LUKS RD_NO_LVM rd_NO_MD quiet elevator=deadline rhgb rd_NO_DM mpath.wwid=360a9800050334c33424b334163434546

After upgrade from rhevh 6.5 for 3.4.z(RHEV-H 6.5-20150115.0.el6ev
) to 20150128.0.el6ev. wwid already kernel cmdline after upgrade, and rhevh 6.6 start successful. 

And the backup rhevh 6.5 for 3.4.z(RHEV-H 6.5-20150115.0.el6ev) also can boot successful. 

Test machine is Z600-03

So this bug is verified on rhevh side, and the kernel bug 1179728 was fixed yet as well.
