I have an automated process for keeping the TSM servers at our DR site,
in synch with production.  This is a home grown app (mostly Korn shell)
and it has been working well for several years.  The problem is that
twice in the past week, the restore of the TSM DB at the remote site has
failed.  Things worked just fine for 5 days between the two incidents.

 

Both servers are running the same (old) versions of TSM (5.1.6.3) and
AIX (5.1.0.5).  

 

The database backup is done to disk, I then tar-up some additional
system files, compress everything and FTP it to the remote site.  

Everything unpacks successfully.  

Checksums are the same on both sides.  

I keep a week's worth of databases on both sides - I can reproduce the
error, by simply attempting to restore the same database backup - so I
know there's something wrong with the backup itself.

DBVol, and logvols are identical between the servers, and neither is
pressed for space 65 and 40% utilization respectively.

The database has actually been much larger - so, I know it's not a
physical or logical limit - currently the DBB flat-file is about 10GB.

 

If I can't figure out what's causing the issue - is anyone aware of a
utility that I can run against the DBB file that might find the problem
before I send it to my DR site? 

 

Below is the output from the restore at the point that it fails - as you
can see it appears to have completed, but then it blows up.
