Does /dev/mapper/mpathep1 even exist?
Yes it does. I've experimented with this and discovered that if I have 4 SAN disks the install will succeed but the fifth will make it fail. mpathe is the 5th disk.
Where are we on this one? Is it still happening as of snapshot 8?
I'll try snap 8 tomorrow, 7/23.
I Hit the bug on what will be snap-8 RHEL6.0-20100722.0.
Can you attach /tmp/program.log as well?
