Kevin,
That snippet is only the part of the %pre that dealt with
discovering and ignoring SAN disks. Here's the full %pre ... The
mptscsi section is for the VMware virtual machines. The cciss is for
the HP ProLiant SmartArray-based systems. Also, for RHEL4 virtuals
we're not using local dump space and only a 17G virtual disk, so it gets
different partition table. And we're using LVM on the OS drive
regardless.
