Hi

The problem isn't moving only one TSM server, but consolidating two TSM 
servers into one.

I have no problems moving the first TSM server(ADSM1) to the new hardware. 
However, I want to migrate the second TSM server(ADSM2) to the new 
hardware/TSM server(TSM1). There are two choices for doing this, either 
exporting all nodes using export node option. This will generate alot of 
tapes, as the smallest ADSM server has 200 nodes, 1500 tapes and a total 
storage of 30TB. However, I can choose not to export the copypools, which 
would make it about 15TB of data and 750 tapes.

The other option is to do a export server. This command has a filedata= 
feature, and what I would like to do is to do a export server 
filedata=none, and then import this information into the new TSM server. 
The new TSM server will have access through ACSLS/3494 CU to all existing 
volumes from both old ADSM servers. Therefore, I wouldn't have to export 
all the filedata, only definitions.

My question is, is it possible to do a export server filedata=none, and 
then import this information into the new server, connect both the 3494 
and the STK9310 to the new server, and use the old volumes that contains 
data and already exists in the 3494/STK9310.

This would save me 3-4 days, because that is what it would take to move 
15TB of data from the 3494 to the 9310 using import/export commands.

Or, do I have to do export/import of all filedata, because doing 
filedata=none, will only import node definitions, and not storage volume 
definitions?

If you stay on the same platform-OS, all you need to do is shutdown (old 
server) after a final DB backup, move the HW connections to the new 
server, restore DB, and you're finished.  Remember to copy the dsmserv.dsk 
(filesystems for all TSM server files -- db, log, disk pool vols, logical 
volumes, path-names), as well as volhist, devcfg and dsmserv.opt; 
move/re-org filesystems *after* the move.  Many other posts confirm this 
approach, have personally done it on AIX since v2 days.

  Hi

  Anybody out there know if it's possible to do a export server, without 
having to export all filedata, and then do a import and use the existing 
tapes.

  We have one STK 9310 and one IBM 3494. Each TSM server has a copypool 
and a primary tape pool in the different libraries. All equipment is SAN 
connected, so if I could first do a DB backup/restore to the new machine 
of one of the TSM servers, and then export everything except for the file 
data from the second TSM server to the new machine, it would be perfect.

  Doing a export server filedata=all, would create about 1500 new tapes, 
according to a export server preview=yes (about 31TB of data) and this 
would probbaly not work at all.

  So, anybody done this before?

  Best Regards

  Daniel Sparrman
