Hi Ron,
If a VSAM dataset is allocated with a candidate list of volumes VOLSER=(VOL001,VOL002,VOL003 ), the datset will allocate to the first volser in the list, then the next, etc. The catalog entry will show all of the volumes, even if there is no VTOC entry there yet . Back a few years ago, when we had much smaller volumes, we had some large VSAM datasets (non-SMS) that we allocated this way.

I archived it and clipped the volumes and out [Ron Hawkins] I'm a little surprised to hear that an empty VSAM dataset was allocated across five volumes. As most of your references are pre-SMS or non-SMS I'd be interested to know how it got that way without guaranteed space.
