– DEVSUPxx for PROD is shown in Example I-7 for the categories that apply for PROD. 

## DFSMSrmm definitions 

COMPACT=YES, MEDIA1=0011, MEDIA2=0012, ERROR=001E, PRIVATE=001F, VOLNSNS=YES 

GLYPH<SM590000> COMMANDxx can be used to vary the range of devices online after IPL: 

– For TEST, apply a specific range of devices as shown in Example I-8. 

COM='V 10E0-10FF,ONLINE' COM='V 20E0-20FF,ONLINE' 

– For PROD, apply a specific range of  devices as shown in Example I-9. 

COM='V 1000-10DF,ONLINE' COM='V 2000-20DF,ONLINE' 

In this case study, DFSMSrmm is the TMS. Equivalent definitions must be defined if you prefer to use another vendor’s TMS. These defi nitions can be created by using options in DFSMSrmm PRTITION  and OPENRULE . PRTITION  is the preferred method for partitioning. REJECT commands, although still supported, are less powerful and work differently than PRTITION and OPENRULE  commands. 

If you use REJECT  commands, convert from the use of REJECT  commands to use the PRTITION and OPENRULE  commands. You can use this method of soft partitioning with or without SDAC. However, with SDAC, the extra protection of the library that is refusing to mount a volser that is not defined as accessible, which is a complete and thorough method of partitioning that does not rely on correctly configuring the TMS on all sharing hosts. 

For more information about options for DFSMSrmm, see z/OS DFSMSrmm Implementation and Customization Guide , SC23-6874. 

The definitions that are needed in this specific case study are listed in Table I-2.
