Keep in mind RH goes out of their way to ensure things don't break.
After all your paying for that with RHEL :)

Breakage occurs in the FOSS world all the time. While I haven't run into
said problems with mounting lvm volumes, its not a chance I want to take
either. Then again a simple tweak of a config file could cause your lvm
partitions to go undetected just the same ;)

Like the filter directive, snippet from /etc/lvm/lvm.conf

"A filter that tells LVM2 to only use a restricted set of devices."

A couple examples that would not see other drives or lvm volumes on them

sata/scsi
filter = [ "a|/dev/sd[abcd]|", "r/.*/" ]

HP raid arrays
filter = [ "a|/dev/cciss/c0d0p|", "r/.*/" ]
