8860ch13.fm Draft Document for Review September 23, 2019 1:06 am The HCD now returns to the Channel Path List panel showing you the CHPID that was just  defined (Figure 13-22). The only way to define an OSA connection to its Control Unit is direct connected. You might want to connect the OSA Control Unit definition to multiple CPCs even though the  physical OSA is still unique to any one CPC. Also, you might want to span the OSA over  multiple CSSs within a CPC. The following are considerations for connecting an OSD CHPID to an OSA Control Unit and  its OSA/OSAD devices: To define OSD CHPID connections to an OSA Control Unit, complete these steps: GLYPH<SM590000> How many OSAs are required to provide a primary and secondary/backup network  connection. GLYPH<SM590000> The example will be connecting to a predefined OSA Control Unit (1E10) and OSA  devices 1E10-1E1E and OSAD device 1E1F. 1. From the main HCD panel, select option 1.4. Control units . 2. Scroll through the Control Unit List until you find the control unit you want to connect to, or  in the command line enter  L 1E10 . In our example, we use 1E10. 3.
