Adding network devices
This chapter describes how to define OSC, OSD, OSE, OSM, and IQD CHPIDs; Control Units; and devices.
It includes a list of these potential configuration items and a short description of how to complete each item by using the Hardware Configuration Definition (HCD) tool.
 
Note: Not all of the configuration items that are described in this chapter are necessarily required for your installation. Also, the examples that are presented are not intended to be exhaustive.
This chapter includes the following topics:
13.1 Defining more I/O using HCD
When defining new I/O components in an IODF, specific definitions, such as OSCONFIGs, partitions, FICON Switches, Control Units, and Devices, must be made up front. After the following items are defined, the connections can be made:
OSC CHPIDs
OSC CHPID connections to an OSC Control Unit
3270-X devices to an OSCONFIG
3270-X devices to NIP within an OSCONFIG
OSD CHPIDs
OSD CHPID connections to an OSA Control Unit
OSA and OSAD devices to an OSCONFIG
OSE CHPIDs
OSE CHPID connections to an OSA Control Unit
OSA and OSAD devices to an OSCONFIG
OSM CHPIDs
OSM CHPID connections to an OSM Control Unit
OSA-M devices to an OSCONFIG
IQD CHPIDs
IQD CHPID connections to an IQD Control Unit
IQD devices to an OSCONFIG
The I/O definitions that are described next use the HCD tool to demonstrate the examples. The examples continue by using the example that was created in Chapter 5, “Production IODF and setting up the CPC” on page 85 (for example, ITSO.IODF78.WORK).
13.2 OSA CHPID definitions
This section describes defining OSC, OSD, OSE, and OSM CHPIDs and their control units and devices.
13.2.1 Defining OSC CHPIDs
When defining an OSD or OSE connection, you first must determine which type of OSA card you need for your configuration. OSC connections use the copper-based OSA Express6S 1000BASE-T card:
Optical connection cards:
 – OSA Express6S GbE SX or LX
 – OSA Express6S 10 Gb SR or LR
Copper-based connection cards: OSA Express6S 1000BASE-T
A new OSC CHPID includes the following considerations:
Channel path ID (CHPID)
Channel ID (CHID)
Channel path type
Operational mode
Description
Partition access list
For performance and redundancy, how many I/O cards of that feature are installed in the processor and to what PCIe ports on what CPC drawer that the I/O cards connect to (see the PCHID/CHID report for a list of installed hardware)
To define a new OSC CHPID, and provide access to a partition, complete the following steps:
1. From the main HCD panel, select option 1.3. Processors.
2. Enter s next to the Processor that you want to add a CHPID to, and press Enter.
3. Enter s next to the CSS ID that you want to add a CHPID to, and press Enter.
4. In the command line, enter add (see Figure 13-1) to add a CHPID.

13.2.2 Defining OSC CHPID connections to an OSC Control Unit
The only way to define an OSA connection to its Control Unit is direct connected.
You might want to connect the OSC Control Unit definition to multiple CPCs even though the physical OSC is still unique to any one CPC. Also, you might want to span the OSC over multiple CSSs within a CPC.
Consider the following points for connecting an OSC CHPID to an OSC Control Unit and its 3270-X devices:
How many OSCs are required to provide a primary and secondary/backup network connection.
In our example, we connect to a predefined OSC Control Unit (1B10) and 3270-X devices 1B10-1B1F.
To define OSC CHPID connections to an OSC Control Unit, complete the following steps:
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 that you want to connect to or in the command line enter L 1B00. In our example, we use 1B00.
3. Enter c next to the Control Unit definition, and press Enter.
4. Make any changes to the Control Unit definition that you want (see Figure 13-4), and press Enter.

8. By pressing F20 (Right), you can see the other parts of the definition summary.
13.2.3 Defining 3270-X devices to an OSCONFIG
The OSCONFIG name is the part of an IODF that determines what devices a z/OS system can access when it IPLs. The partition that the z/OS system is restarted in also must access the CHPIDs that connect to the Control Units and Devices that match in the OSCONFIG.
The OSCONFIG also contains Esoterics device groups, which are defined in EDTs within an OSCONFIG. OSA definitions often do not use Esoterics.
Consider the following points for adding devices to an OSCONFIG:
Adding a device to an OSCONFIG does not necessarily mean that the z/OS system can access that device.
In our example, we add the predefined OSC devices 0800-080F (3270-X).
To define 3270-X devices to an OSCONFIG, complete the following steps:
1. From the main HCD panel, select option 1.5. I/O Devices.
2. Scroll through the I/O Device List until you find the device number that you want to add to the OSCONFIG or in the command line, enter L 0800. In our example, we use 1B10.
3. Enter c next to one or more Device numbers, and press Enter.

10. The final panel is now displayed in which the devices that are defined to the OSCONFIG are shown. Press Enter to return to the I/O Device List.
13.2.4 Defining 3270-X devices to NIP within an OSCONFIG
The NIP Console list determines the device addresses that are eligible to receive nucleus initialization program (NIP) or IPL messages in the early startup stages of when z/OS is started.
The devices first must be defined to an OSCONFIG so that they can be added to a NIP Console list within an OSCONFIG.
The NIP console list also determines which console receives the NIP/IPL messages first. If that console is unavailable, NIP tries the next device in the list until all devices in the list are tried.
If NIP cannot write IPL messages to any 3270-X device in the list, the messages are written to the HMC Operating System Messages panel.
To view these messages, complete the following steps:
1. Select the LPAR for IPL on the HMC.
2. Click the >> breakout symbol that is next to the LPAR name.
3. Select Daily  Operating System Messages, as shown in Figure 13-12.
Figure 13-12 Operating System Messages
Commands and displays can be entered in the Command box (see Figure 13-13).
Figure 13-13 Operating System Messages command interface
Consider the following points for adding devices to a NIP console list within an OSCONFIG:
Adding a device to a NIP console list within an OSCONFIG does not necessarily mean that NIP can write IPL messages to that device.
The devices that are defined in the NIP console list also need Control unit and CHPID access to the partition into where z/OS is being started.
On the HMC, under OSA Advanced Facilities, the OSC (OSA-ICC) console Server and Session definitions also must be defined and activated.
A valid 3270-X session (that uses IBM PCOM or an equivalent 3270 emulator) also must be connected to the OSA-ICC Session. This configuration allows a valid session to be established to the OSA-ICC for NIP messages to be delivered to that device.
Our example adds the predefined OSC devices 1B10-1B11 (3270-X).
To define 3270-X devices to NIP within an OSCONFIG, complete the following steps:
1. From the main HCD panel, select option 1.1. Operating system configurations to display the Operating System Configuration List.
2. Scroll through the list of OSCONFIG definitions until you find the OSCONFIG that you want to add to the 3270-X devices to the NIP console list, or in the command line enter L ITSOTEST. In our example, we use ITSOTEST.
3. Enter n next to the OSCONFIG, and press Enter.
HCD displays the currently defined devices in the NIP Console List (see Figure 13-14).

13.2.5 Defining OSD CHPIDs
When defining an OSD or OSE connection, first you must determine which type of OSA card you need for your configuration. OSD and OSE connections can use optical or copper-based cards. The type of card that is used depends on the type and speed of network to which you want to connect your OSAs. The following types of cards are available:
Optical-based:
 – OSA Express6S GbE SX or LX
 – OSA Express6S 10 Gb SR or LR
Copper-based: OSA Express6S 1000BASE-T
A new OSD CHPID includes the following considerations:
Channel path ID (CHPID)
Channel ID (CHID)
Channel path type
Operational mode
Description
Partition access list
For performance and redundancy, how many I/O cards of that feature are installed in the processor and to what PCIe ports on what CPC drawer do the I/O cards connect to (see the PCHID/CHID report for a list of installed hardware)
To define a new OSD CHPID and provide access to a partition, complete the following steps:
1. From the main HCD panel, select option 1.3. Processors.
2. Enter s next to the Processor to which you want to add a CHPID. Press Enter.
3. Enter s next to the CSS ID to which you want to add a CHPID. Press Enter.
4. In the command line, enter add (see Figure 13-18) to add a CHPID.
5. Complete the following updates and press Enter:
 – Channel path ID to B8.
 – Channel ID to 148.
 – Channel path type to OSD.
 – Operational mode to SHR.

13.2.6 Defining OSD CHPID connections to an OSA Control Unit
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.
Consider the following points when connecting an OSD CHPID to an OSA Control Unit and its OSA/OSAD devices:
How many OSAs are required to provide a primary and secondary/backup network connection.
Our example connects to a predefined OSA Control Unit (1B80) and OSA devices 1B80-1B8E and OSAD device 1B8F.
To define OSD CHPID connections to an OSA Control Unit, complete the following steps:
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 1B80. In our example, we use 1B80.
3. Enter c next to the Control Unit definition, and press Enter.
4. Make any changes to the Control Unit definition that you want (see Figure 13-23), and press Enter.

13.2.7 Defining OSA and OSAD devices to an OSCONFIG
The OSCONFIG name is the part of an IODF that determines which devices a z/OS system can access when it IPLs. The partition that the z/OS system is started in also must access the CHPIDs that connect to the Control Units and Devices that match in the OSCONFIG.
The OSCONFIG also contains Esoterics device groups, which are defined in EDTs within an OSCONFIG. OSA definitions often do not use Esoterics.
Adding devices to an OSCONFIG includes the following considerations:
Adding a device to an OSCONFIG does not necessarily mean that the z/OS system can access to that device.
Our example adds the predefined OSA devices 1B80-1B8F (OSA/OSAD).
To define OSA and OSAD devices to an OSCONFIG, complete the following steps:
1. From the main HCD panel, select option 1.5. I/O Devices.
2. Scroll through the I/O Device List until you find the device number that you want to add to the OSCONFIG, or in the command line enter L 1B80. In our example, we use 1B80.
Because OSA and OSAD are two different device types, they must be added separately to the OSCONFIG.
3. Enter c next to one or more Device numbers, and press Enter.
4. HCD displays the Change Device Definition panel where you can modify the Control Unit to which the devices are attached (see Figure 13-27). Press Enter.

13.2.8 Defining OSE CHPIDs
When defining an OSD or OSE connection, you must determine which type of OSA card you need for your configuration. OSD and ODE connections can use optical or copper-based cards, depending on the type and speed of network to which you want to connect your OSAs. The following cards are available:
Optical based cards:
 – OSA Express6S GbE SX or LX
 – OSA Express6S 10 Gb SR or LR
Copper-based card: OSA Express6S 1000BASE-T
A new OSE CHPID includes the following considerations:
Channel path ID (CHPID)
Channel ID (CHID)
Channel path type
Operational mode
Description
Partition access list
For performance and redundancy, how many I/O cards of that feature are installed in the processor and to what PCIe ports on what CPC drawer do the I/O cards connect to (see the PCHID/CHID report for a list of installed hardware)
To define a new OSE CHPID, and provide access to a partition, complete the following steps:
1. From the main HCD panel, select option 1.3. Processors.
2. Enter s next to the Processor that you want to add a CHPID to, and press Enter.
3. Enter s next to the CSS ID that you want to add a CHPID to, and press Enter.
4. In the command line, enter add (see Figure 13-32) to add a CHPID.

13.2.10 Defining OSA and OSAD devices to an OSCONFIG
The OSCONFIG name is the part of an IODF that determines which devices a z/OS system can access when it IPLs. The partition that the z/OS system is started in also must access the CHPIDs that connect to the Control Units and Devices that match in the OSCONFIG.
The OSCONFIG also contains Esoterics device groups, which are defined in EDTs within an OSCONFIG. OSA definitions often do not use Esoterics.
Adding devices to an OSCONFIG includes the following considerations:
Adding a device to an OSCONFIG does not necessarily mean that the z/OS system can access that device.
Our example adds the predefined OSA devices 1B90-1B9F (OSA/OSAD).
To define OSA and OSAD devices to an OSCONFIG, complete the following steps:
1. From the main HCD panel, select option 1.5. I/O Devices.
2. Scroll through the I/O Device List until you find the device number you want to add to the OSCONFIG, or in the command line enter L 1B90. In our example, we use 1B90.
Because OSA and OSAD are two different device types, they must be added separately to the OSCONFIG.
3. Enter c next to the Device numbers, and press Enter.
4. HCD displays the Change Device Definition panel where you can modify the Control Unit to which the devices are attached (see Figure 13-40). Press Enter.

13.2.11 Defining OSM CHPIDs
When defining an OSM connection, you must determine which type of OSA card that you need for your configuration. OSM connections use the copper-based OSA Express6S 1000BASE-T card. The following cards are available:
Optical based cards:
 – OSA Express6S GbE SX or LX
 – OSA Express6S 10 Gb SR or LR
Copper-based card: OSA Express6S 1000BASE-T
The following are considerations for a new OSM CHPID:
Channel path ID (CHPID)
Channel ID (CHID)
Channel path type
Operational mode
Description
Partition access list
For performance and redundancy, how many I/O cards of that feature are installed in the processor and to what PCIe ports on what CPC drawer do the I/O cards connect to (see the PCHID/CHID report for a list of installed hardware)
To define a new OSM CHPID, and provide access to a partition, complete the following steps:
1. From the main HCD panel, select option 1.3. Processors.
2. Enter s next to the Processor that you want to add a CHPID to, and press Enter.
3. Enter s next to the CSS ID that you want to add a CHPID to, and press Enter.

13.2.12 Defining OSM CHPID connections to an OSM Control Unit
The only way to define an OSA connection to its Control Unit is direct connected.
You might want to connect the OSM 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 OSM over multiple CSSs within a CPC.
Connecting an OSM CHPID to an OSM Control Unit and its OSA-M devices includes the following considerations:
How many OSAs are required to provide a primary and secondary/backup network connection.
Our example connects to a predefined OSM Control Unit (1B10) and OSA-M devices 1B10-1B1F.
To define OSM CHPID connections to an OSM Control Unit, complete the following steps:
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 that you want to connect to, or in the command line enter L 1B10. In our example, we use 1B10.
3. Enter c next to the Control Unit definition, and press Enter.
4. Make any changes to the Control Unit definition that you want (see Figure 13-49 on page 332), and press Enter.

13.3 IQD CHPIDs for Hypersockets
This section describes the process to define IQD CHPIDs and their control units and devices.
13.3.1 Defining IQD CHPIDs
When Hypersockets must be defined, the CHPID type of IQD (Internal Queued Direct Communication) is used. Since z13, the IQD CHPID also requires the VCHID statement. The valid range for the VCHIDs are 7E0 - 7FF.
As with ICP CHPIDs, IQD CHPIDs are defined logically and internally to the processor and require no installed hardware (PCHIDs). However, from z13, a maximum of up to 32 high-speed virtual LAN attachments can be defined.
Each of the logical IQD VCHIDs can support only 1 CHPID; however, the CHPIDs can be spanned across multiple CSSs.
A new IQD CHPID includes the following considerations:
Channel path ID (CHPID)
Channel ID (vCHID)
Channel path type
Operational mode
Description

13.3.2 Defining IQD CHPID connections to an IQD Control Unit
The only way to define an IQD connection to its Control Unit is direct connected.
You might want to span the IQD CHPID over multiple CSSs within a CPC.
Connecting an IQD CHPID to an IQD Control Unit and its IQD devices includes the following considerations:
How many IQDs are required to provide the required Hypersocket bandwidth.
Our example connects to a predefined IQD Control Unit (F100) and IQD devices 0FC0-0FCF.
To define IQD CHPID connections to an IQD Control Unit, complete the following steps:
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 F100. In our example, we use F100.
3. Enter c next to the Control Unit definition, and press Enter.
4. Make any changes to the Control Unit definition that you want (see Figure 13-61), and press Enter.

13.3.3 Defining IQD devices to an OSCONFIG
The OSCONFIG name is the part of an IODF that determines which devices a z/OS system can access when it IPLs. The partition that the z/OS system is started in also must access the CHPIDs that connect to the Control Units and Devices that match in the OSCONFIG.
The OSCONFIG also contains Esoterics device groups that are defined in EDTs within an OSCONFIG. IQD definitions often do not use Esoterics.
Adding devices to an OSCONFIG includes the following considerations:
Adding a device to an OSCONFIG does not necessarily mean that the z/OS system can access that device.
Our example adds the predefined IQD devices 0FC0-0FDF (IQD).
To define IQD devices to an OSCONFIG, complete the following steps:
1. From the main HCD panel, select option 1.5. I/O Devices.
2. Scroll through the I/O Device List until you find the device number that you want to add to the OSCONFIG, or in the command line enter L F100. In our example, we use F100.
3. Enter c next to one or more Device numbers, and press Enter.
4. HCD displays the Change Device Definition panel where you can modify the Control Unit to which the devices are attached (see Figure 13-65 on page 343). Press Enter.
