Scott,

   I am just reading this on Tuesday so please if someone already replied just
ignore this. From you post :

<07/26/1999 11:54:02  ANR1255W Files on volume 010187 cannot be restored -
<                      access mode is "unavailable" or "offsite".
<07/26/1999 11:54:02  ANR1255W Files on volume 010182 cannot be restored -
<                      access mode is "unavailable" or "offsite".

  From what I understand if the tapes that you need to restore have an access of
'OFFSITE' this is the result that you will get. You need to set the access of
these volumes to readonly or read/write. ADSM can't restore from a copypool if
the access of the volume is 'OFFSITE'. If I misunderstand this could someone
please let me know!!

                              Thanks,
                                 Brian

Thanks for all of the responses.  Let me clarify a few things...

I have only one storage pool on-site, "3590TAPE" which is a primary storage
pool.  I have a copy storage pool called "disaster-recovery" which as the name
implies is where my DRM points to for DR.  The tape I lost was in the primary
storage pool.  I first tried the "restore vol 010172 preview=yes" and found the
following in my activity log:

07/26/1999 12:02:24  ANR2017I Administrator ADMIN issued command: RESTORE
                      VOLUME 010172 preview=yes

                      Restored: 0.
07/26/1999 12:02:26  ANR1256W Volume 010172 contains files that could not be
                      restored.

This is when I called IBM.  They looked at my actlog and then went through the
properties of my storage pools.  They told me
that there was something set differently in a DRM storage pool and that it used
a different database.  He said that
because of this, ADSM did not know about the state or contents of off-site tapes
 and could therefore not re-build a tape
on-site from that media.  It was then that he told me the only way to do tape
restores was to have a second copy pool that
was not controlled by the DRM.

In Chapter 21 of the ver3 Admins guide, page 453, bottom paragraph, the first
sentence reads:  "Copy storage pools that
you may not want DRM to manage can include on-site copy storage pools used for
recovery from media failures."  That is
the only place I have found anything remotely similar to what the ADSM support
person told me.

After reading all of your responses, I conducted an experiment.  I tries the
restore vol command with the preview option on
another volume and got...

This leads me to assume that the restore of an individual volume would normally
work but that there was some problem
as yet undetermined that the first restore failed to work.

To add to the confusion, I could query the contents of the offending volume.
When I ran the restore command it warned me
that I would loose all the information on the volume being restored.  I ran it
anyway.  After which, I could still query the
contents of that volume.  The literature made me think that it would remove all
database pointers to that tape but it
did not...

Does this story jive with what you have experienced?

So, assuming that I can do a tape restore, I now have a new and scary problem.
That is that we are paying a lot of money
for ADSM support.  I opened a call of the highest priority and the person I
talked to did not know the product and made us
contemplate dropping ADSM completely!
