Before proceeding with the following topics, study the relevant information concerning creating the SMS definitions in Using ISMF panels to define and monitor your configuration, and the z/OS DFSMSdfp Storage Administration. This book, along with the online ISMF functional and help panels, explains the items you specify using ISMF.
8 Define the base SCDS.
The procedure for defining a source control data set is provided in z/OS DFSMSdfp Storage Administration. It is possible to define several source control data sets describing different configurations; however, only one SCDS can be activated at any time.
9 Define the tape libraries.
You need to define your tape library to add the library record to the TCDB and the library definition to the specified SCDS. Choose option 3, DEFINE, on the ISMF Tape Library Application Selection panel (Figure 3) to display the ISMF Tape Library Define panel shown in Figure 4 and in Figure 6. When defining the Peer-to-Peer VTS Subsystem, remember to define not only the composite library but also the underlying distributed libraries.
10 Define tape storage groups.
Use ISMF to define your tape storage groups and the library names associated with the storage groups. For more information on how to define tape storage groups, see z/OS DFSMSdfp Storage Administration and z/OS DFSMS Implementing System-Managed Storage. To direct allocation to a Peer-to-Peer VTS Subsystem, the composite library should be used and not the associated distributed libraries.
11 Define storage classes.
Use ISMF to define storage classes that cause the installation storage group filter routine to select tape storage groups. The storage class determines whether or not a request is SMS-managed. If a storage class is not assigned, the request is not SMS-managed.
12 Define data classes.
Define data classes to direct your nonspecific requests to a specific media type and recording technology, and to specify whether compaction is required. You may also specify performance scaling, performance segmentation and encryption key label information in your data class definitions. Choose option 4 on the ISMF Primary Option Menu panel to display the ISMF Data Class Define panel to define your data classes.
13 Write and test ACS routines.
Create or modify the installation’s storage class, data class, and storage group ACS routines to select tape constructs for certain types of new data requests. There can be only one set of ACS routines in an active configuration. See z/OS DFSMSdfp Storage Administration for information on using ISMF to define ACS routines.
