Defining a sysplex couple data set to MVS

z/OS MVS Setting Up a Sysplex
SA23-1399-00

You define sysplex couple data sets to the system on the PCOUPLE and ACOUPLE keywords of the COUPLE statement of the COUPLExx parmlib member, for example,
COUPLE PCOUPLE(SYS1.XCF.CDS01)
       ACOUPLE(SYS1.XCF.CDS02)

IBM® recommends that you define at least two COUPLExx members that specify different sysplex couple data sets. Then, if the primary sysplex couple data set fails before or during IPL, another COUPLExx member is available for the operator to specify.
