ONBar Restores and Tivoli Storage Manager

I am having problems with restores from ONBar via Tivoli Storage Manager (TSM). I can perform backups that complete fine according to the logs, and the verification using "onbar -v" reports successful with no errors. However when I go to attempt a restore, I get one of two situations: 1) Cold restore results in a backup corrupted message as follows: Unable to write storage space restore data to the database server: The archive backup is corrupted.. 2) Warm restore results in the restore process starting and then it just sits there with no information being written to the onbar logs - after waiting for 30 minutes for 100 meg database, I figured that the process must be hung. Can anyone provide any ideas, insight, or references on Onbar and TSM? sending to informix-list
