You're NOT supposed to get any message to which you have to reply DOWN!

The correct way to shut down a system in a sysplex is to ALWAYS ALWAYS 
use vary xcf,sysname,offline. Then reply with the name of that system again. 
(This is true for monoplexes, also!)

Remember that the IXC402D (reply down when mvs has been system reset) is 
an ERROR condition message. Issued by XCF on another system after 90 
seconds when the system in question does not update its couple CDS 
heartbeat anymore (and does not communicate via XCF signalling anymore). 
The reason for that failure to communicate *should* always be a 'real' error on 
that system and never due to that system just getting its icon dragged in the 
course of normal shutdown.

The purpose of vary xcf offline is to tell all connectors to all XCF groups in 
that sysplex that a system will shortly be going away and do cleanup on behalf 
of that system. Failure in that cleanup can lead to really ugly problems during 
restart.
