Everything else has partitions, so you need to run "kpartx" on each multipath device to create mappings for partitions. Did you enable multipathd service (I thought it should call kpartx or maybe a udev rule)? I saw device mapper reload ioctl failures when you enabled the VGs. The LVM scan seems to use single paths rather than multipath devices (from duplicate PV messages). So run "kpartx -a /dev/mapper/<yourmultipathdevice>" on each multipath device and then run LVM scan. If LVM still uses paths and complains about duplicate PVs, then you may need create a right filter in /etc/lvm/lvm.conf to use intended devices. I hope this is not necessary.
