2. Use the ALTER MEDIADEFS command to change the tape level support on all
three nodes to MEDIACAT:
MC> ALTER MEDIADEFS, LEVEL MEDIACAT
MC> ALTER MEDIADEFS \SEA, LEVEL MEDIACAT
MC> ALTER MEDIADEFS \STAR, LEVEL MEDIACAT
Because \SKY is the default node, you need not include its name in the first ALTER
MEDIADEFS command.
Adding Tape Volumes to Pools, or Preexisting
Tape Files
This subsection shows how to configure the main DSM/TC components:
Adding Tape Volumes to Pools
The ADD TAPEVOLUME command is used to add tape volumes to pools when they
are already labeled. If tapes are not prelabeled, use the LABEL TAPEVOLUME
command.
Examples

You have 50 prelabeled scratch tapes to catalog, named C00001, C00002, and so
on, up to C00050. Because of the sequential numbering scheme in the names, you
can take advantage of the COUNT option of ADD TAPEVOLUME:
MC> ADD TAPEVOLUME C00001,&
>>> COUNT 50,&
>>> POOL OPR_TAPES,&
>>> VOLCAT MASTER_TAPE_CATALOG,&
>>> LABELS ANSI
There are 50 new volume catalog entries for tape names C00001 through C00050.

This example catalogs three cartridge tapes with IBM labels. Because they are
given a status of released, they cannot be used as scratch tapes until an ALTER
TAPEVOLUME command is used to change their status to scratch in the catalog.
MC> ADD TAPEVOLUME (CRT445, CRT446, CRT451),&
>>> POOL CARTRIDGE_TAPES_5120,&
>>> VOLCAT MASTER_TAPE_CATALOG,&
