Imported Restore with TSM and 2 engines with same DBSERVERNAME

IDS 10.00.UC5 I have a production Informix engine with a DBSERVERNAME of engine1 running on server1 backing up to TSM and I have a test Informix engine with a DBSERVERNAME of engine1 running on server2 backing up to TSM. Both instances have SERVERNUM set to 1. Does anyone know if there will be any issues with performing an imported restore of the production engine1 to the test engine running on server2? I'm wondering how onbar knows to ask TSM for the right restore files if the rootdbs level 0 backup files for test and production both look like /engine1/engine1/rootdbs/0 Can there be other issues with this configuration? Could running onsmsync on the test engine incorrectly expire logical log backups for the production engine in TSM? Would giving the test engine a different SERVERNUM fix this? Thanks in advance, Andrew
