It makes little difference. Save yourself the aggravation. Such planning is best done with a working knowledge of the hardware. That seems to be missing along with why that's important. It follows that any arguments would not make any sense to them.
As for doc, I am fond of the portion of the hardware planning manuals that describe the physical layouts and the considerations for carving up the box. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Murray M. Robinson Sent: Tuesday, January 08, 2008 2:35 PM To: [email protected] Subject: Old habits with new DS6000 and DS8000 I am finding hard to persuade some old time IBM developers that planning to disperse dataset allocation as if they were accessing old discreet 3390 disks is a futile effort. Ignoring that with PAV and WLM goal mode and 3390s only logical and no one really knows were all the pieces are stored on the much fewer physical disks emulating thousands of volumes. I suggest use SMS without requesting Guaranteed space and placing their datasets on specific volumes is not getting through to them. Please help direct me to some decent documentation explaining this. Also if anyone knows when this technique is still relevant I'd love to know. Also which RMF screen gives a good snapshot of IO activity (and caching) Thanks. Murray Robinson ACI Worldwide, Inc.
