If PROMPT is specified, the system waits for the length of the operator notification interval (the OPNOTIFY value in COUPLExx) and then notifies the operator with message IXC402D.

As always when responding to the IXC402D prompt, it is important to take the appropriate reset action to reset the system image, and then reply to the prompt, in a timely fashion. Otherwise, resources held by the system will be unavailable to the rest of the sysplex. It is also crucial that this prompt not be responded to until the appropriate reset action has been taken, or data integrity problems may result. Note that the system reset action that is taken prior to responding to the prompt will cause RESERVEs held by the target system to be released.
