5. Make the following updates (Figure 14-1) and press Enter : 

– Update Partition Name  to ARIES2E  (a naming standard based on CSS=2, Partition =E). 

## 14.2.2 Defining CS5 CHPIDs 

– Review Partition usage  and change if required. We use CF in this example. 

– Update Description  to ARIES2E test CF partition .

When defining a CS5 CHPID to create a Coupling Facility link between a Coupling Facility LPAR and a z/OS LPAR, first determine which z/OS LPARs require access to which CF LPAR, how many CF links are required, and to how many different physical processors. 

CS5 coupling facility CHPIDs are defined using FC 0176 (ICA SR 2 Links) cards that are installed on the CPC drawer as opposed to in the PCIe+ I/O drawer. 

The ICA SR card has two ports (Port 1 and Port 2) that provide two physical connections to another ICA SR card on the same or different processor. 

Each of the ports can have up to four CHPIDs defined to these ports. 

The following are considerations for a new CS5 CHPID: 

GLYPH<SM590000> Channel path ID (CHPID) 

GLYPH<SM590000> Channel path type 

GLYPH<SM590000> Operational mode 

GLYPH<SM590000> Description 

GLYPH<SM590000> Adapter ID (AID) 

GLYPH<SM590000> Adapter Port 

GLYPH<SM590000> Partition access list
