8860ch12.fm Draft Document for Review September 23, 2019 1:37 am HCD now returns back to the Select Processor / CU panel showing the CHPID ( 15 )  connection definition (Figure 12-14). Although a mixture of FICON switched and FICON direct connections are not recommended  to the same Control Unit, this configuration is possible.  A typical scenario could be if you were moving from direct connected DASD to FICON switch  connected DASD, but you were not able to take the DASD offline to live systems. The OSCONFIG name is the part of an IODF that determines what devices a z/OS system  will have access to when it IPLs. Additionally the partition that the z/OS system is restarted in  also needs to have access to the CHPIDs that connect to the Control Units and Devices that  match in the OSCONFIG. The OSCONFIG also contains Esoterics device groups and are defined in eligible device  tables (EDTs) within an OSCONFIG. Esoterics device groups are used to request allocation of a device that has been defined in an  Esoteric device group when using the UNIT = parameter in a  JCL DD  statement. However, this  allocation can be overridden or intercepted by using DFSMS. The OSCONFIG name includes these items: GLYPH<SM590000> EDT ID (Eligible Device Table ID): Esoterics / VIO GLYPH<SM590000> Consoles 12.2.4 Defining 3390B devices to an OSCONFIG and EDT/Esoteric Select Processor / CU Row 1 of 18 More:  Command ===> _______________________________________________ Scroll ===> CSR  Select processors to change CU/processor parameters, then press Enter.
