ALTER MEDIADEFS Command (Super Group or
SECURITY-MEDIA-ADMIN Only)
SSLIST { \command-node }
{ ( \command-node [ , \remote-node ] ... ) }
creates the system search list for a node. If DSM/TC is installed on only one node,
specify command-node only. If DSM/TC is installed on several nodes, specify
command-node and the remote node names in any order in the list.
Once you create a system search list, you can use a subsequent ALTER
MEDIADEFS command to change it.
RESET SSLIST
changes the system search list to contain only the name of command-node.
VOLCAT \node.volume-catalog-name
is the logical name of the volume catalog to use when no name is given in a
TAPECATALOG DEFINE. It also becomes the session default name for a volume
catalog when not explicitly set with the VOLCAT command.
Include \node when the volume catalog is not on your current default node.
Considerations

System updates
When you use the ALTER MEDIADEFS command to update a system, the
NonStop Kernel tape server processor, $ZSVR, must have create access for
$SYSTEM.SYSTEM (or the SYSnn where ZSVRCONF is located), as well as read
and write access to the ZSVRCONF file.

Default values on multiple nodes
If your DSM/TC system serves more than one node, when establishing default
values with ALTER MEDIADEFS:

Name the same volume catalog and set the same abend retention, tape
support, and retention period values on all nodes.

Name a different pool on each node.

Name a different file catalog on each node.
For more information on configuring DSM/TC, see the DSM/TC configuration
guidelines in the DSM/Tape Catalog User’s Guide.

Using the AUTOMATED option
Use the AUTOMATED option only when most or all of your tapes are stored in a
tape library. When you have a tape library and this option is set to on, you optimize
Note. The SSLIST on all nodes must be the same for interoperability among nodes. For
example, a remote node must include the command node for interoperability between the
two nodes.
