I'm assuming, from your question, that you do not have a directory that
maps your volume.

I've developed a tool for use during disaster recovery exercises called
DISCOVER.  If you do not have a directory map of your volume, you can run
DISCOVER to at least learn where your minidisks are.  Then, by using the
output from ICKDSF, which will show you the system areas of the pack, you
can get a pretty good idea of what's where, without a directory.

If you want, I'll send you the tool.  In principle, all it does is use CP
DEFINE MDISK to define a 1 cylinder MDISK at progressively higher cylinder
numbers, trying to CMS ACCESS that minidisk.  If it works, the results from
QUERY MDISK will tell how big CMS thinks the minidisk is supposed to be,
and DISCOVER then appends this information to a map file, the information
being the CMS volser, the starting cylinder, and the size of the minidisk.
DISCOVER also has the option to redefine the minidisk at its correct size
so it can be used.  Handy if you need to discover where MAINT 190 or the
parm disks are ...

It is interesting how often I've had to use this tool after it was built -
in one case someone had to recover data from backups of a defunct VM
system, and although you could restore the tapes (they were DDR), there was
no directory that said where the minidisks were.  Were it not for DISCOVER,
I couldn't have helped them.
