Hello All!
I am running RedHat AS 2.1 2.4.9-e3custom kernel (Many reasons why so
old)... I have compiled in the the default LVM and multipath options in
the kernel. I have also compiled in the new drivers for my FC Cards
(Qlogic 2300). I can see all my storage... However! I cannot seem to
get the multipathing to work. I see all 6 drives (3 from each card)...
Is there a magic trick to get the multipathing to work? I am at a loss
here...

If you are using MD multipathing, you need to edit/create an
/etc/raidtab file and then run mkraid or raidstart. You then use a
/dev/md* device to access your storage.

I got the MD device setup in raidtab I am using the "multipath"
personality... It is not utilizing both paths though... I started a
write, then pulled the active path to simulate failure, and it just died
:) fun fun... thanks for the help!
