This is what I get when I run pvscan.  pvs is similar.

# pvscan
   PV /dev/sda4   VG main_huge_vg   lvm2 [529.00 GiB / 0    free]
   PV /dev/sdb2   VG main_huge_vg   lvm2 [594.25 GiB / 0    free]
   PV /dev/sdc1   VG main_huge_vg   lvm2 [931.50 GiB / 0    free]
   PV /dev/sdd1   VG main_huge_vg   lvm2 [698.62 GiB / 0    free]
   PV /dev/sde1   VG main_huge_vg   lvm2 [931.50 GiB / 0    free]
   Total: 5 [3.60 TiB] / in use: 5 [3.60 TiB] / in no VG: 0 [0   ]
