Hi Riaan,
Welcome to our 'world'...
your short list covers the essentials, although the extra TSM snapshot I
would deem unnecessary. I'll let a. n. other bod(s) chat about other
approaches..
You cannot load in a tape and expect TSM to read it and know what to do with
it. The TSM database tracks the location of all the files it receives and
when tapes are loaded they're either to move data onto froma client or from
another tape/disk residing within the TSM storage heirarchy, or to perform
restores. Essentially, TSM can only read from a tape it wrote to, and even
then it knows what the volume contains.
Assuming you have some flavour of UNIX, a good idea might be to
'dd /dev/(full path to device) > /(path to file)'
copy the contents to disk and examine it from there.
Perhaps there are 'better' ways of doing this, but I can only think of this
one right now.
'cpio and 'tar' may prove to be better choices depending on the format of
the data currently residing on your tape.
Hope this helps.

Subject: TSM: DB Best Practises ?
Hi There,
Been monitoring the list the last couple of weeks. Seeing as we are
relatively new to the "world of TSM".
I havent come across this (yet) in any of the admin / installation / user
guides but I woudl like to know if there is a "best practises" w.r.t
maintaining our tivoli server. (this is where the personal experience out
there REALLY comes in handy ...) I have already drawn up a short list - feel
free to add to it ....
Daily Backups
Reclamation (daily)
Migration
Create Offsite Copies
Expiration
Backup TSM DB
SnapShot TSM DB
Backup Volhist
Expire Inv
If possible any integrity or consistency check that we can run to verify
the DB ? TSM internal commands ? or external utilities ?
Second Question: (I know I am pushing it - but seeing as I already have the
guru's attention) - Does TSM have a utility that "scans" in a tape and
re-populates the DB ? Example: We have a tape and we arent sure what data it
contains - can one "scan" (for lack of a better term) the contents ? Can one
restore from that tape (say to a temp location) to view the contents ?
Any help is appreciated.
Regards,
Riaan Louwrens
