Creating Pools

To create a file and volume catalog on the same subvolume of the current default
node (the catalogs have the same logical names; this is required when the file and
volume catalog are on the same subvolume):
MC> CREATE FILECAT TAPE_CATALOG,&

>>> SUBVOL $IRIS.TAPECAT,&

>>> SECURE “NC-O”,&

>>> OWNER 5,149


MC> CREATE VOLCAT TAPE_CATALOG,&

>>> SUBVOL $IRIS.TAPECAT,&

>>> SECURE “NC-O”,&

>>> OWNER 5,149
Creating Pools
To add tape pools to DSM/TC, use the MEDIACOM ADD POOL command. Your site’s
tape librarians should determine how many tape pools are necessary for your system.
HP recommends that you create separate pools for different media types and for
different label types.
If you create append pools, they should contain only labeled tapes.
Examples

To create a pool of open reel tapes with ANSI labels and a density of 1600 bpi:
MC> ADD POOL TEST_TAPES,&

>>> VOLCAT MASTER_TAPE_CATALOG,&

>>> DENSITY 1600,&

>>> LABELS ANSI,&

>>> TYPE OPEN
ADD POOL Option Description
SEARCHSPACE
INCLUDED Specifies that the pool is included in the system search space. This is
the default. This option means that all tape names must be unique
within the entire system search space.
Once a pool is established as included or excluded, you cannot
change it with an ALTER POOL command. To change a pool’s search
space attribute, you must delete the pool and re-create it.
SEARCHSPACE
EXCLUDED Specifies that the pool is excluded from the system search space. Use
this option for special cases, such as managing tapes from another
site that have the same names as tapes at your site.
DSM/TC does not recognize a tape belonging to a pool excluded from
the system search space when mounted on a tape drive. When a tape
from an excluded pool is needed, the tape drive name must be given
in the TAPECATALOG DEFINE using the DEVICE attribute.
