Draft Document for Review February 7, 2020 3:15 pm 8464axStats.fm Enabling AS support is shown in Example I-3. Example I-3 GRS definition to enable AS support /*------------------------------------------------------------------*/ /* Enable AS support */ /*------------------------------------------------------------------*/ RNLDEF RNL(INCL) TYPE(GENERIC) QNAME(SYSZVOLS)  Note:  A Parallel Sysplex normally includes a shared TMS - plex (TMSplex), SMSplex,  and TCBD. However, it is possible to define separate TMSplex, SMSplex, and TCDBs if  complete segregation of volser ranges is wanted  GLYPH<SM590000> IECIOSxx. In this member, you can define specific device ranges and you must separate  TEST from the PROD updates: – TEST updates are shown in Example I-4,  one line for each range of devices. The  MOUNTMSG parameters ensure that the console receives the Mount Pending  message ( IOS070E ) if a mount is not complete within 10 minutes. You can adjust this  value. It depends on many factors, such as read/write ratio on the connected host and  available capacity in the grid. Example I-4 IECIOSxx updates for specific TEST device addresses MIH DEV=(10E0-10FF),TIME=45:00 MIH DEV=(20E0-20FF),TIME=45:00 MIH MOUNTMSG=YES,MNTS=10:00 – PROD updates are shown in Example I-5, one line for each range of devices. Example I-5 IECIOSxx updates for specific PROD device addresses MIH DEV=(1000-10DF),TIME=45:00 MIH DEV=(2000-20DF),TIME=45:00 MIH MOUNTMSG=YES,MNTS=10:00 GLYPH<SM590000> DEVSUPxx. In this member, you can define specific tape library categories to be used on  each system. You must use a specific and separate DEVSUPxx parmlib member for TEST  that specifies different categories from the PRODDEVSUPxx parmlib member. In this  example, you need a unique VOLCAT.VGENERAL that continues the library entries for  each LPAR but might share the specifics volcats with the volume entries if you are not  using SDAC and want to read the volumes from either LPAR: – DEVSUPxx for TEST is shown in Example I-6  for the categories that apply for TEST. Example I-6 DEVSUPxx updates for specific TEST category COMPACT=YES, MEDIA1=0021 MEDIA2=0022, ERROR=002E, PRIVATE=002F, VOLNSNS=YES  Appendix I.
