If you allow sequential-access storage pools to use scratch
volumes, you do not need to define volumes. You can control the maximum
number of scratch volumes that the server can request by using the MAXSCRATCH parameter
on the DEFINE STGPOOL and UPDATE STGPOOL command.
About this task
To allow the storage pool to acquire volumes as needed,
set the MAXSCRATCH parameter to a value greater
than zero. The server automatically defines the volumes as they are
acquired. The server also automatically deletes scratch volumes from
the storage pool when the server no longer needs them.
Before
the server can use a scratch volume with a device type other than
FILE or SERVER, the volume must have a label.
Restriction: Tivoli® Storage
Manager accepts
only tapes that are labeled with IBM® standard
labels. IBM standard labels
are similar to ANSI Standard X3.27 labels except that the IBM standard labels are written
in EBCDIC (extended binary coded decimal interchange code). For a
list of IBM media sales contacts
who can provide compatible tapes, go to the IBM website. If you are using non-IBM storage
devices and media, consult your tape-cartridge distributor.
