After documents are migrated to archive storage as a result of running arsmaint, is there a way to look somewhere and find out which document went to what node and what location on the storage device?
You can run some queries on the TSM server - query content (of a specific volume), and query filespace. But to get what you're looking for, you may need to run a select statement against the database tables directly. If you're on TSM 5.x, this could be painfully slow, as the database engine at the heart of TSM isn't a full-featured database product like DB2. If you're on TSM 6.x, DB2 is the database under TSM, so you have a lot more flexibility.
