In TSM, files (not nodes) are associated with management classes. When files are sent from the client to the TSM server, they are bound to a management class, as can be controlled from the client. Once in TSM server storage, file management classes cannot be changed by any command. The only way to change the management class of a file is to send the file to the TSM server again, with a reformulated Include statement in effect for Backup, or an Include,Archive or ARCHMc spec for Archive. This discipline is in effect because enterprise level data retention calls for retention values which are set and known at file commit time, and which are not subsequently tinkered with by someone beyond the client realm. Refer to "Binding and rebinding management classes to files" in the client manual.
