[linux-lvm] Changing dev_t-devname mapping in lvmlib seems to be problematic

We are using LVM with SAN and multipathd. I try to setup mirroring with LVM. So I do pv create on a mpath device. vgcreate, add the pv to the vg, create a lv and setup a mirror with this:
lvconvert -m1 vg<name>/lv<name> /dev/mapper/mpath0 --mirrorlog core
My intention is to create a logical volume which can handle SAN Disk failure.
But in this shown setup i get a error (unavailable logical volume) when one of the san LUNS is missing.
Can this system work or did i need to setup a mdadm device before pvcreate ?
Hope you can help me because Redhat can't... them sitting two weeks on this error / miss configuration without any solution...
