While following the messages about the DELETE VOLHIST command, I
checked to
see what we did with this command.  I "inherited" ADSM from someone
else
and there is little documentation for what was done or why it was
done.
What I found is this:

delete volhist todate=today-21 type=dbbackup
                     (runs
every Sunday)
delete volhist todate=today-5   type=stgdelete
                       (runs
every Sunday)
(type can also be stgreuse and export)

I also found a "volume history" file with entries for "stgnew" going
all
the way back to 1996.  Can anyone think of any reason why these might
have
been kept?  Could my predecessor just have overlooked these?

TIA,
Nancy
