NAME(cfname) Specifies the 1 - 8 character length name of the coupling facility. The valid characters are uppercase alphabetic characters (A-Z), numeric characters (0-9),
national characters ($,@,#), or an underscore (_). The cfname must start with an alphabetic character (A-Z). Consider defining your coupling facility name to match the
name of the LPAR in which the coupling facility is to run.
