Issue

Previously, users have never had to define the VOLSER variable from the Linux guest when using RHEL4 or RHEL5. Installation is completely automated using a kickstart server and trying to label each dasd uniquely during the kickstart would be risky at best. If one disk was accidentally mis-labeled it could crash another guest. This has previously been set outside of the Guest Operating System.
When installing Red Hat Enterprise Linux 6, the installer does not see the VOLSER when using the -k option.

Environment

zSeries IBM Hardware as virtualization host
