I strongly disagree. Unless explicitly asked, no IBM utility should EVER update disks, regardless of link mode. Nowhere in the DSF documentation does it ever refer to updating data when using CPVOL LIST. All the references are to "read". > It isn't unreasonable, I think, for DSF to take the > opportunity to fix the VTOC w.r.t. alternate cylinders if the > count is non-zero. It's reasonable for it to ASK whether it can fix it. Just "going ahead and fixing it" without asking is not at all reasonable, unless you're signing up to explain it to customer security people at your expense. I don't think you want that responsibility.
