Re: DEVICES Statement in SYSTEM CONFIG
IMO - that's the best/safest way to do it.It forces you to specify the volumes you actually want online to z/VM.. Your post says that on your system all devices come online at IPL time though? That's the opposite approach and not as 'safe'... Scott Rohling On Fri, Sep 3, 2010 at 4:30 PM, Martin, Terry R.

Re: DEVICES Statement in SYSTEM CONFIG
Thanks Scott. If I am going to vary them offline anyway as the first thing via the SYSTEM CONFIG and vary the ones I want online isn't that basically the same as having them come up offline via the IOCDS?
