7. Select any Candidate LPARs for Function access list. In our example, we do not  select any candidate LPARs. Press Enter. 

HCD returns to the PCIe Function List panel in which you can see the Function now defined (see Figure 15-13).

8. Define the other Function IDs according to the example thus far (see Figure 15-14).

## 15.2.4 Defining a zEDC EXPRESS PCIe function 

The zEnterprise Data Compression (zEDC) uses a PCIe hardware card for the z14 ZR1called zEDC Express FC#0420. 

To use zEDC hardware functions, Function IDs and Virtual Function IDs must be defined in HCD to the PCHID that was assigned to the zEDC hardware cards that are installed in the processor. Similar to defining a CHPID to a PCHID for FICON and OSA type channels, Function IDs and Virtual Function IDs are assigned zEDC PCHIDs. 

This example shows only the definition process. For more information about how zEDC works, see Reduce Storage Occupancy and Increase Operations Efficiency with IBM zEnterprise Data Compression , SG24-8259.
