Exchanging a volume

You should exchange a volume (replace one volume with another volume) if a volume meets any of the following conditions:

Full (in this case, to exchange a volume means to remove the volume from a robotic tape library).
Past the maximum number of mounts.
Old (past the expiration date).
Unusable (for example, because of repeated media errors).

The exchange volumes procedures in the following subsections depend on whether you want to reuse the old media ID or not.
