I have never seen 'regions' defined in EXTENT CONTROL as anything other than the corresponding DASD volser. I can see how it might be used if you were really into carving up DASD volumes strategically -- but I believe those days are long gone.
Anyway - I'm putting together some best practices revolving around DASD, DIRMAINT, EXTENT CONTROL - and one thing I planned to list is to ensure that the regions listed match the volsers. I've been bitten by mismatches (someone duplicating a line but failing to change the 2nd word -- the volume) and want to eliminate them. So my question is this: Does anyone at all actually specify regions in EXTENT CONTROL on a DASD volume that have a different name then the DASD volser? If so - is there an advantage you can tell me about? Thanks! Scott
