Making a selection on the previous panel will allow you to define I/O device definition.
One of the options is for the Explicit Device Candidate List. The purpose of the Explicit
Device Candidate List is to limit which LPARs have access to a particular resource in an
EMIF environment. In the case of the SCON, it is necessary to limit access to each host
circuit to one LPAR. Below is the related help information.

Explicit Device Candidate List

Specify a value for this field only if the designated
processor type-model has ESCON Multiple Image Facility
(EMIF) capability.

Indicate whether you want to explicitly specify in a
device candidate list, which partitions, defined in the
IODF for the processor, should be allowed to access the
device being added or changed, or the group being changed.

To change the displayed value, either type over or delete
Yes or No. No is the default.

Yes

to explicitly define a device candidate list.

The Define Device Candidate List panel is displayed
when Yes is specified. You can then select the
partitions that you want to be allowed to access
the device or device group.

No

not to explicitly define a device candidate list.
All partitions are allowed to access the device or
device group.
