Products and subsystems that exploit the XCF Note Pad Services might have preferences as to whether their note pads should reside in a duplexed structure. XCF will try to honor the duplexing preference when creating a new note pad, but will not fail the create request if it is unable to do so. However, hosting the note pads in a less preferred structure might have a negative impact on the performance or availability goals of the exploiter.

Connectivity should also be considered when defining the coupling facility preference list for a note pad structure. A system must have connectivity to the note pad structure for exploiters residing on that system to access the note pads.
