Peter, We used to IPL our systems without the V XCF,<sysname>,OFFLINE. That worked for years until we started to run into issues with signaling structures (one of the systems would occasionally not use one of the signaling structures after an IPL). We opened a PMR and IBM's response was to perform the V XCF as per <http://www-03.ibm.com/systems/z/advantages/pso/removing.html>. We changed our IPL procedure and haven't seen the problem since. (This was back in z/OS 1.10)
So yes, we did see an impact with not using the V XCF OFFLINE.

There are some situation in our shop when one of our Development LPAR do undergo to unresponsive state(This happens when our developers do some destructive testings or many other factors) and even we cannot issue any commands on Console. To resolve this we just do a de-activate and activate to re-ipl the system. As a normal IPL procedure we issue V XCF,OFF,SYSNAME=something. Will there be any impact to the system when we do not issue the V XCF,OFFLINE and just do a de-activate and activate ?
