You might want to look at lvm.conf.  Typically lvm looks at /dev/sda,
/dev/sdb and so on.  What you will likely want it to do is look at the
multipath device vs. the individual device.

Just remember to test your changes prior to any reboot.  Otherwise your
change could knock off another lvm device on the system.
