I assume its a single external drive, and the LG its a part of doesn't
have any other PVs?

Plug the drive into any machine and run

vgscan # to find the volume group
vgexport # make the VG ready to import
vgimport # make the VG known to the system
pvscan # find the physical volumes

vgchange -ay # make the logical volumes known to the kernel (the
device nodes will be created)

You should now be able to mount the logical volume
