Designate a Dump Volume
You should always have a designated dump volume. For more information, see
DUMPVOLUME on page 3-19.
Designate an Alternate Volume Set
You should always have a designated set of alternate disk volumes. For more
information, see ALTERNATE-VOLUMES on page 2-16.
Designate a Disallowed Volume Set
If you do not want TFDS to use certain disk volumes for storing files related to failures,
you should designate these volumes as disallowed disk volumes. For more
information, see DISALLOWED-VOLUMES on page 2-16.
