I have a volume group on removable media: backvg3 Normally, I run
"vgchange -an backvg3" before removing the media. However, today the
customer removed the media to an offsite location for safekeeping before I
could do the vgchange. This shouldn't be a big problem, because the
filesystem was mounted read-only (a precaution against exactly this
occurence).
However, I can't get rid of the VG.

The physical device, /dev/sdc, is gone. What should I do? If I leave it
until the media is brought back, is it safe to reattach? What if it does
not reattach at the same SCSI disk (say /dev/sde instead)?
