Side

A value that identifies the coupling facility to a specific physical side (side 0 or side 1 of a physically partitioned machine) of a CPC running in Physically Partitioned mode.  For ES/9000 processors, the information is available from the processor controller. Values for the NAME and PARTITION
parameters appear on the LPDEF frame and appears on the ECSTAT frame. Use caution when splitting or merging physical sides of a processor that contains a coupling facility. The action might change the SIDE information that identifies the coupling facility.

Valid values: 0, 1, or None
