What's in ASP2 ?

Question:

How can I tell what is stored in ASP2?


Background:

A small shop with a first generation 520 running V5R4 with some
disks separated into a user ASP (ASP2). The primary function of ASP2 was to
support two integrated widows servers but these servers are no longer
needed. There's a need to increase the disk capacity in the primary disk
pool (ASP1) but the system is currently maxed out in the number of drives it
can support without adding another disk expansion, etc. and adding back the
disks from ASP2 will give the system enough extra disk capacity for at least
another year.

I know the virtual disks for the integrated servers are on ASP2 and
I've generated an outfile from DSPOBJD OBJ(*ALL/*ALL) OBJTYPE(*LIB)
and found a couple of archival type libraries stored on ASP2. How can I find
out if any other items such as IFS folders are stored in ASP2?

After a full system backup, I plan to delete the libraries stored in ASP2,
delete the IWS configurations and the virtual disks and then look at the
% capacity used on the ASP2 disks. Hopefully it will be at or very near
zero. Then I will delete ASP2 and add the disks to the configuration for
ASP1 with a capacity load balance included. Finally, I will restore the
archival libraries deleted from ASP2 to ASP1.

Thanks in advance for any pointers.
