>How can i delete a file which resides on 3590 tape? If it was via a Backup, you don't directly delete it: TSM policies expire it. If it was an Archived file, you use the B/A client to delete the instance.
I'd strongly recommend reading the TSM documentation to get more familiar with the product you are trying to use. Start with the Backup/Archive Clients manual, and then review the Admin manual.
