provided the driver was unlocked successfully it seems unrelated to
cryptsetup/LUKS to me. Could we move the discussion to lvm mail list?

Could you paste here output of pvscan -vvvv --cache
/dev/mapper/insert_the_unlocked_device_name? Together with your
/etc/lvm/lvm.conf file? If it's a device with rootfs we're talking about
you will most probably have to extract /etc/lvm/lvm.conf file from
Well, generally, if disk sectors accommodating PV header are damaged,
lvm2 won't recognise the device...

Ok, try same approach as above for this drive.
