We are doing the same thing here, although with older versions of TSM: TSM v
5.5.5.0 on AIX6.1.
We dump the TSM DB to a DD690, replicate to a DD580 at a DR site. Then we kick
off a script to restore the DB to a standby TSM server at the DR site.
In testing we did fulls, and fulls+incr and commits and we have not had any
errors. We've only been doing it for about a month now, but the process runs
every morning to load the full DB backup (to keep the DR site warmer and
readier to go) and I haven't had a failure yet. The DB is 150GB, in one 150GB
file we load from.
My script wipes out the DB every time before loading the DB dump. I don't think
it's necessary, but I do it just for a clean slate. The command looks something
like this:
dsmserv format 1 /dev/rlogvol 4 /dev/rdbvol1 /dev/rdbvol2 /dev/rdbvol3
/dev/rdbvol4
Not sure what the issue could be to cause it to fail intermittently. Hopefully
it's not related to the TSM server version, because we will eventually have to
go to 6.X.
Sorry I'm no help in this case.

Subject: [ADSM-L] TSM 6.2.2. restore from Data Domain 880
Is anybody else performing Disaster Recovery testing of AIX 6.1 TSM 6.2.2.0 by
restoring the database directly from a Data Domain 880 file device?
My problem is that I can restore the database some of the time, and get
"ANR4522E RESTORE DB failed with LOG file error." the rest of the time. I have
opened PMR 36668,122 but the tech seems to think the problem is that I'm using
a script to generate the db restore command, despite the fact that I've
explained that the problem is intermittent.
I've copied the database files to local storage prior to a restore attempt. If
I can restore from the local copy I can restore directly from the DD880. If
the local copy restore files with a log file error, the DD880 restore has the
same problem. It looks like corrupted Db backup files are being written
(sometimes). I'm searching through logs and would appreciate any suggestions.
