A PCIe function is defined by a unique identifier, the
function ID (FID). Each function specifies
a function type (ROCE or ZEDC-EXPRESS) and a physical channel identifier PCHID.
Multiple functions may be specified to the same PCHID value provided
that each of these functions defines a unique virtual function VF number. When defining a PCIe function, you
may specify a description which is shown in this list.
Use PF20=Right to scroll to the partition assignments for the displayed PCIe functions,
one panel for each defined channel subsystem.

You define a new PCIe function specified by its required function ID, function type and PCHID value,
the virtual function number (if possible for the specified function type), and a description.
After pressing the Enter key, the LPARs can be selected that should be entitled to
access the function. If you specified an Add-like action, the data
entry fields, except the function ID, and the LPAR connections are
preset with the values of the selected source function.
Each PCIe function is identified by a three-digit hexadecimal
function ID that is unique within a processor configuration. You must specify a function type (ROCE or ZEDC-EXPRESS),
and a PCHID value which describes the related PCIe adapter card in the assigned
slot of the I/O drawer. Depending on the function type, multiple PCIe
functions may be defined for the same PCHID by assigning a unique
virtual function number to each of these functions.
HCD also supports overgenned PCIe functions. You define overgenned PCIe
functions by providing an asterisk (*) for the PCHID value.
Overgenned functions are validated like other PCIe functions but they
are excluded from the IOCP input statements and from dynamic activation.
Depending on the function type, you can assign up to four physical network IDs to a PCIe function.
Each physical port of the PCIe adapter can be assigned to a (possibly different) physical network. If you
press the Enter key, for example, for a function of type ROCE, HCD
displays the Add/Modify Physical Network IDs window where you can enter a
physical network ID (PNET ID) for each physical port of the adapter.
The sequence of the PNET IDs corresponds to the sequence of the port numbers on the adapter card.
Add/Modify Physical Network IDs
If the PCHID is associated to one or more physical networks, specify
each physical network ID corresponding to each applicable physical port.
Physical network ID 1 . . PNET01__________
Physical network ID 2 . . PNET02__________
Physical network ID 3 . . ________________
Physical network ID 4 . . ________________

If you press the Enter key either on the Add/Modify Physical Network IDs
window for PCIe functions of type ROCE, or directly on the Add PCIe Function
window for PCIe functions of type ZEDC-EXPRESS, HCD displays the Define
Access List window, where you can specify one partition to be connected to the defined PCIe function.

Pressing Enter again leads you to the Define Candidate List window.
Here you can modify the candidate list of partitions assigned to the PCIe function.
You can define partitions from any channel subsystem.
