ISMF provides a library management function to allow the storage administrator to use a series of panels to define the tape libraries needed for their installation.
To define a tape library, select option 10, LIBRARY MANAGEMENT, from the ISMF Primary Option Menu (as shown in Figure 1) to start the library management dialog.

SCDS NAME and LIBRARY NAME are output fields that contain the SCDS and library name you specified in the Tape Library Management Application Selection panel.
When the number of scratch volumes in the library falls below the scratch volume threshold for that media type, operator action message CBR3660A is issued requesting that scratch volumes of the required media type be entered into the library. When the number of scratch volumes exceeds twice the scratch volume threshold for that media type, the message is deleted.
When the second define panel is complete, use the DOWN command to display the third part of the Tape Library Define panel (Figure 6). Continue with the definition for library LIB1 by completing part three of the Tape Library Define panel. You may also need to use part four of the Tape Library Define panel (Figure 7).

A tape library can be connected to any combination of one or more of the systems or system groups defined in the CDS base, but it is strongly recommended that the tape libraries be connected to systems rather than system groups. When a tape library is connected to a system group, the user loses the ability to vary the tape library online or offline to the individual systems in the system group. The ISMF Tape Library panels support both system names and system group names.
The system administrator defining the libraries does not need to be logged on to one of the systems in the SMS complex to define the libraries in that complex—both the TCDB and the SCDS can be moved after being created. However, both the SCDS and the TCDB for the SMS complex being defined must be available to the system administrator during the library definition process.
The definition for the tape library does not take affect until the SCDS to which it is defined is activated. Once the library is defined within the SCDS and the record for the library is updated in the TCDB, the attributes assigned to the last defined library for the SCDS are displayed on the Tape Library Application Selection menu and the Tape Library Define panel as defaults. These values can be modified to define other libraries as needed.
After you complete the definition of LIB1, the Tape Library Application Selection menu (Figure 3) is displayed again, and you can define your second tape library as follows:
The Tape Library Define panels (Figure 8, Figure 9, Figure 10, and Figure 11) are again displayed, and you enter the appropriate information for LIB2.

After completing these library definitions, you have two libraries—one ATLDS library, LIB1, along with an MTL library, LIB2—defined in the SMS configuration. Defining a tape library using the Tape Library Define panels adds a library record to the TCDB along with the library definition into the specified SCDS.
