If the missing PV is reattached to your system - you need to

vgextend --restoremissing   /dev/path_to_PV


Since once the PV is detected as missing - metadata are update on present PVs,
and the missing PV is marked as MISSING.
When such PV reappear - you need to run the command to re-synchronize metadata.
