Fixed In Version: ovirt-node-2.3.0-6.el6 Doc Type: Bug Fix
Doc Text:
When upgrading, the Hypervisor would sometimes fail to find the root partition correctly. This was due to findfs commands occasionally returning pointers to /dev/dm-* devices instead of /dev/mapper/<wwid> devices. The output from findfs is now run through a translation function that will resolve devices to a location under /dev/mapper in all cases.

Verified with rhevh-6.3-20120509.1, rhev-h update with "linux upgrade" successes without any exception. The updated rhev-h boots up successfully.
