Additional configuration requirements for using secondary host promotion

The following requirements apply to the use of secondary host promotion:

If the ARCCBEXT exit is used by the primary host, it must be available for use on all hosts eligible to be promoted for the primary host. If the ARCMMEXT exit is used by the SSM host, it must be available for use on all hosts eligible to be promoted for the SSM host.
The CDS backup data sets must be cataloged on all systems that are eligible to be promoted for primary host responsibilities.
In a multisystem environment, DFSMShsm always sets the option to NOSWAP.
