1. It is possible
2. No, you need the DRM license (part of Extended Edition) to have
server-to-server virtual volumes
3. To the virtual volumes device class, i.e. to a file stored in "MS"
server
3b. Yes, it depends on the destination setting of the "MS" server
copygroup
4. See the answers to q.3 & 3b.
999. No matter of the setup or version :-) You just need enough "RS" disks
and rather good pipe to "MS".

        Subject:        TSM Storage Pool Hierarchy Question


Alright, time to ask the experts!

Essentially, I'm trying to have our remote TSM servers (satellite
locations) utilize the main TSM server as the next storage pool in it's
hierarchy.

The hierarchy will eventually look like this:

Remote Server (RS) Disk Cache
  -Main Server (MS) Disk Cache
     -MS Tape Pool
         -MS Offsite Copy Pool

Questions I have:
1) Is this possible?
2) Can I do this without the DR module?
3) How does the RS backup it's database - because it won't backup to
the local disk?
3b) Should the RS backup it's DB directly to tape? and if so, how is it
possible to share the tape library with no NAS?
4) Should I just break down and put some tape drives out there to
handle the DBs?

Current setup:
  MS: W2k sp4, TSM v4.3.2, IBM 3853 w/ 54 slots & 2 LTO drives.
  RS: W2k sp4, TSM v5.2.0

Thanks everyone.
