If your TMS is DFSMS Removable Media Manager (DFSMSrmm), see the following publications for more information: 

GLYPH<SM590000> DFSMSrmm Primer , SG24-5983 

GLYPH<SM590000> z/OS DFSMSrmm Implementation and Customization Guide , SC23-6874 

If this installation is the first SMS tape library at this host, more steps are required. The full product documentation for your TMS must be consulted, in addition to the OAM PISA. 

## 6.3.1 Defining the TS7700 in a z/OS SMStape environment 

Complete the following steps to define the TS7700 tape library in a z/OS SMStape environment: 

1. Use the ISMF Library Management → Tape Library → Define  window to define the tape library as a DFSMS resource. Define the composite library and one or more distributed libraries. Library names cannot start with a “V”. In the following figures, we define one composite library that is named IBMC1 and a single distributed library that is named IBMD1. 

Remember:  Library ID is the only field that applies for the distributed libraries. All other fields can be blank or left as the default. 

Figure 6-7, Figure 6-8 on page 242, and Figure 6-9 on page 242 show defining the composite tape library.
