I do have a setup as you describe, but my TSM servers are AIX hosts using NFS 
mounts to the DDR. 

In my situation, I just NFS mount up the second DataDomain under the same mount 
points and the TSM server has no idea that it's from a different DataDomain. 

Not sure how you would do it with a CIFS mount... sorry.

Subject: [ADSM-L] Using Datadomain for replication

Anyone out there using a DDR as the primary FILE devclass, having it replicate 
to a 2nd DDR in a recovery site and having to do a TSM recovery using the 2nd 
DDR?



Are you using the UNC path name for the DEVCLASS or a drive mapping? This is 
strictly Winders and CIFS, not NFS.



What I'm coming up against is at the 2nd site after restoring the DB all my 
volumes still point to the primary DDR UNC name. I can change the DEVCLASS, but 
that doesn't seem to effect the existing volumes, only new volumes. So unless I 
also rename the 2nd DDR to the name of the primary DDR, all my volumes are 
basically unavailable.



Just wondering how anyone else using DDR replication for TSM.
