When migrating a Linux VM from RHV to OCP-V the serial number is not properly preserved/presented to the VM. While the disk serial number is used for the disk name in the vm definition, this ends up as "drive-ua-<disk name>" at the OS layer, which causes issues for LVM and fstab when using the drive serial number for identifying the volume. 

Potential solution is to use the "serial:" attribute to properly pass the disk serial number to the OS.
