Extra IODF examples
This appendix describes input/output definition file (IODF) and input/output configuration program (IOCP) examples for several different configurations.

Important: These examples are not preferred practices or suggested configurations to be adopted. They are for reference only and must be tailored to your environment and needs.

This appendix includes the following topics:
General IODF principles
When you set up an IODF you define up to four (or six with IBM z13) channel subsystems (CSSs), which logical partitions (LPARs) are in which CSS, which channel-path identifiers (CHPIDs) are defined to which LPARs, which control units (CUs) use which CHPIDs, and which IODEVICEs are defined to which CUs. The IOCP is a text file that can be migrated to an IODF, or all the definitions can be done by using the Hardware Configuration Dialog (HCD).
A CHPID is a two-digit value from 00 to FF depending on how many and which CHPIDs are defined to the processor. Physical channel IDs (PCHIDs) represent a physical location on the central processor complex (CPC) and are hardcoded. CHPIDs are arbitrary and plug into the PCHIDs.
PATH is an IOCP statement that is a set of CHPIDs (path group, up to 8) defined to the processor.
A CHPID statement (see Example H-1) specifies the following information:
•The CSS of the LPARs with access to the CHPID
•Whether it is shared (i.e. can be used by more than one system in a CSS on the CPC
•Type of channel
•Which Switch the channel cable plugs into (Hex ID of the switch)
•Which LPARs on the CPC have access to the CHPID
•The PCHID (physical port) on the CPC that the channel cable is plugged into

CHP68 CHPID PATH=(CSS(0),68),SHARED,TYPE=FC,SWITCH=65, X
PART=((ZOS1,ZOS2,ZOS3,ZOS4,ZOS5,ZOS6,ZOS7,ZOS8,ZOS9), X
(=)), X
PCHID=5B8
Using switches to connect to the control unit
LINKs are a two-digit or four-digit (four-digit if the switches are cascaded) ports on a blade in the switch. The LINKs are positional, such that the communication that uses the previous CHPID it exits out the two-digit port that is indicated, so the CPC knows how to address the device it wants to communicate with. The cables from the switch outbound port to the cluster can be plugged into any port on the Hankie card. A cluster looking back at the switch can display which switch port it sees on which Hankie port.
If a CU definition specifies LINKs, multiple CPCs can talk to that cluster if the proper LINKs are used in the IOCP/IODF. LINKs are the same on each CPC, even though the CHPIDs are probably different. The CHPIDs go to the switch that the links are from. The CHPID definition specifies which switch that particular CHPID goes to and the CU definition specifies which outbound port (LINK) goes to that device. A single switch or multiple switches (up to 8) can be used for every CHPID in the PATH statement. It just depends on which switch the CHPID runs to.
A CPC can use fewer than eight ports, but the LINKs are still the outbound switch ports, you have a PATH statement with fewer CHPIDs/LINKs. The cables from the outbound switch ports are arbitrary. They can be connected in no particular order, or can be connected so they mean something to whomever is plugging in the cables, such as to aid in troubleshooting.
Example H-2 shows a CU definition example that uses switches on eight channels.

Directly connecting
In a direct connect situation, there is no switch and the CHPID channel cable connects only to that device and no others. If all the CHPIDs are direct, you can forgo the link statement. The link fields in the IOCP definition are all asterisks, as shown in Example H-3.

Upgrading to 8-Gb channels
There are no changes that are required in the IOCP/IODF to change from 4-Gb channels to 8-Gb channels when the number of devices and number of channels remains the same.
Adding more devices
To add more device addresses for use with the library, add extra CU definitions. In Example H-4, the first 16 CUs (0 - F) are the original 256 devices. The new devices are being added with another 15 CUs (10 - 1E). Except for the CUADD and CUNUMBR addresses specified in each definition, the definitions are identical.

Sharing ports
One CPC can use four ports and another can use the other four ports. You can have up to eight CPCs, each connected to a switched or direct port. Or you can connect all CPCs to all ports (switched). You can also have one CPC that uses all eight ports and another that uses fewer than eight.
Example H-5 on page 927 uses only four CHPIDs/LINKS in each PATH statement. To use the other four ports available on a second CPC, use those values on the first CPC, then change the values, as shown in Example H-6 on the second CPC. The only differences are that the PATHs and LINKs are different values on the second CPC from the first CPC.

LIBPORT-IDs in the MVSCP
Table H-1 of LIBPORT-IDs can be helpful. For Cluster 0, 256 devices are 01 - 10 and 496 devices are 01 - 1F. LIBPORT-ID is always one more than CUADD.
