I want to thank all of you for your patience while I gnashed my teeth
and asked basic questions. Everything is good now. There were so
many things I learned, I'm not sure I'd remember to give credit to
all of them, but some of the main ones are:
1. You've got to include the "exclude" parameter in your "dirm
dirmap" command to activate the "exclude" section in EXTENT CONTROL.
2. "dirm send" and "dirm file" are the way to update EXTENT CONTROL.
3. You can define a 3390-99 in the "defaults" section, telling it
that such a device has 100 cylinders, and then point a volume to it
in the "region" section.*
Now my "dirm dirmap exclude gapfile" command gives me a 100% correct
view of my dasd, showing end-of-volume gaps accurately.
Thank you again.
- Tom.
* While the "dirmap" command in CMS (from CUF) is supposed to
ascertain the size of each volume from the highest cylinder coded on
a mdisk statement for that volume, it doesn't work for my 100
cylinder 3390. It increases the size to 455 cylinders. (Where do
you think that number comes from?) If it weren't for that one
volume, the outpout of the CMS "dirmap" command would be identical to
that of dirmaint's dirmap.
