Adding storage devices
This chapter describes how to define FICON switches and FICON Channel path IDs (CHPIDs), and connect them to a DASD Control Unit. 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 shows only the definition process. For more information about how to use HCD and FICON, see the following publications:
I/O Configuration Using z/OS HCD and HCM, SG24-7804
FICON Planning and Implementation Guide, SG24-6497
This chapter includes the following topics:
12.1 Defining more I/O using HCD
When defining new I/O components in an IODF, certain definitions, such as OSCONFIGs, partitions, FICON Switches, Control Units, and Devices, must be made up front. After these items are defined, the following connections can be made:
The I/O definitions that are described next use HCD 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).
12.1.1 Defining FICON switches (Directors, SANs, and SAN switches)
A new FICON switch includes the following considerations:
Switch ID
Switch type
Serial number (optional)
Description (optional)
Switch address
Installed port range
Switch CU number
Switch device number
To add a FICON Switch by using HCD, complete the following steps:
1. From the main HCD panel, select option 1.2. Switches.
2. In the command line, enter add (see Figure 12-1 on page 277) to add a switch.

12.2.3 Defining FICON CHPIDs for switched connect to a 2107 Control Unit
FICON connections can be defined to a Control Unit by using one of two methods: through a FICON switch or by using direct connect.
The direct connect method mainly is used in an environment where only one processor is present as opposed to FICON switch connection in which multiple processors must connect to the same control units. This situation might not always be the case, however.
Connecting a FICON CHPID to a DASD Control Unit and its devices includes the following considerations:
For performance and redundancy, how many CHPIDs are required to connect to the FICON Switch and then to one or more Control Units?
For FICON Switched connections, a minimum of two FICON switches often are used that the FICON CHPIDs connect through, primarily for failure or service redundancy of the FICON Switches.
In our example, we connect to a predefined 2107 Control Unit (A000), with a CUADD of 40 and devices A000-A0EF (3390B) and A0F0-A0FF (3390A).
 
Note: For FC#0428 FICON Express16S+, defining FC and FCP CHPID types on the same I/O card are not supported. HCD issues the following warning message during a Validate or Build Production for an IODF:
W CBDA963I Chpid type mix detected on processor MUSCA for channels:
0.29, 0.31, 0.30, 0.44
To define FICON CHPIDs for switched connect, 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 A000. In our example, we use A000.
3. Enter c next to the Control Unit definition, and press Enter.
4. Make the following updates for a FICON switch connection (see Figure 12-9), and press Enter:
 – Update Connected to switches to 41. Switch 41 is the switch ID that we defined in the previous example.
 – Update Ports to 11. Port 11 is the FICON switch port that the Control Unit connects to (also known as the Destination Link Address [DLA] of the FICON CHPID).

HCD now shows the Select Processor/CU panel. This panel is where the connection is now made between the FICON CHPID (14) and the Control Unit FICON Switch Port (11) through the FICON switch (41).
5. Enter c next to the Processor.CSS that contains the partition that we want to have access to the control unit and also has access to the CHPID that we want to connect to the control unit. In our example, we use MUSCA.2. Then, press Enter.
6. Complete the following updates to define the Processor / CU connection panel (see Figure 12-10), and press Enter:
 – Channel path IDs to 14. Channel path ID 14 is the CHPID that we defined in the previous example.
 – Link address to 4111. Link address 4111 is FICON switch 41 and Control Unit Port 11.
 – Unit address to 00. Unit address of 00 is the starting unit address number on the CHPID.
 – Number of units to 256. Number of units of 256 equals A000-A0FF (that is, 00-FF or 256).
 – Logical address to 40. Logical address of 40 is the CUADD or the Control Unit Address that is defined in the DS8886 that defines the location of the devices in the DS8886.

Although a mixture of FICON switched and FICON direct connections are not recommended to the same Control Unit, this configuration is possible.
A typical scenario might be if you were moving from direct connected DASD to FICON switch connected DASD, but you cannot take the DASD offline to live systems.
12.2.4 Defining 3390B devices to an OSCONFIG and EDT/Esoteric
The OSCONFIG name is the part of an IODF that determines which devices a z/OS system can access to when it IPLs. Also, the partition that the z/OS system is restarted in must access the CHPIDs that connect to the Control Units and Devices that match in the OSCONFIG.
The OSCONFIG also contains Esoterics device groups and are defined in eligible device tables (EDTs) within an OSCONFIG.
Esoterics device groups are used to request allocation of a device that was defined in an Esoteric device group when the UNIT = parameter is used in a JCL DD statement. However, this allocation can be overridden or intercepted by using DFSMS.
The OSCONFIG name includes the following items:
EDT ID (Eligible Device Table ID): Esoterics / VIO
Consoles
Adding devices to an OSCONFIG and Esoteric includes the following considerations:
Adding a device to an OSCONFIG does not necessarily mean that the z/OS system can access that device.
Does the device need to be added to an Esoteric device group? Mostly, this issue is installation-specific.
The example adds the predefined 2107 devices A000-A0EF (3390B) and A0F0-A0FF (3390A).
To define 3390B devices to an OSCONFIG and EDT/Esoteric, 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 A000. In our example, we use A000.
3. Enter c next to one or more device numbers, and press Enter.
HCD displays the Change Device Definition panel where you can modify the Control Unit that the devices are attached to (see Figure 12-15 on page 289). Press Enter.

Figure 12-16 I/O Devices: Device / Processor Definition continued
5. Next is the HCD panel in which you define devices to the operating system configuration. Scroll through the list of OSCONFIG definitions until you find the OSCONFIG that you want to add to the devices to or in the command line, enter L ITSOTEST. In our example, we use ITSOTEST.
6. Enter s next to the OSCONFIG, and press Enter.
HCD displays the device parameters and features that are applicable to that specific device type. In our example, we are adding 3390B and 3390A devices to ITSOTEST.
7. Complete the following updates to define the Processor/CU connection (see Figure 12-17), and press Enter:
 – OFFLINE to No (if you want these devices to be Online during IPL time)
 – DYNAMIC to Yes (if you want the device to be changeable dynamically)
 – LOCANY to Yes (if the device UCB can be in 31-bit storage)
 – WLMPAV to Yes (if you want the device to be managed by Work Load Manager)
 – READ-ONLY to No (use to set Secondary devices to read only)
 – SHARED to Yes (if the device is going to be shared between other systems)
 – SHAREDUP to No (needs to be set to No is Shared is set to Yes)
