Hi i could't completly understand you

is that true:

you have instaled Redhat on a working sepatarate drive
and you hace added a drive from a crashed system
if this is the case i hope you can run

vgscan -that will tell you the name of the volume group

vgchange -ay volume group name --that activates the volume

if you know the name of the logical volume you should be able to mount it
or if you don't know the name of the logical volume you can find it out 
from proc

cat /proc/lvm/global

you should see all VG'S PV's and LV's

so mount      /dev/ "volume group" / "Logical Volume"    / " where you 
want it" should work





could you give a bit more information
like fstab of the instaled RedHat
