I started this thread because I wanted to get the List's thought/opinion on the
risk. I felt it was low to none and higher on not doing it. Oh well it is all
behind me now I was "allowed" to do it this weekend and guess what, it took
less than 2 minutes ('cause I can't type) and it was successful. Anyway good
discussions and THANK YOU to all who contributed.

Subject: Re: FW: Risk of Adding a Paging Volume
True, and it usually is elsewhere on disks formatted for other operating
systems. For a long while, the TPF disks used to have the last tracks on the
disk contain the VTOC. There were F1 DSCBs for each extent containing
like-sized records. I was speaking in terms of a CP format disk. And as
someone, Alan I believe, pointed out, my memory was a bit fuzzy. The allocation
map precedes the VTOC on them.
