This specific directive within the Tivoli Storage Manager (TSM) environment facilitates the removal of entries from the database that pertain to files which are no longer present in the storage pool. This action ensures that the TSM database remains uncluttered and focused on accurately reflecting the current state of backed-up data. For instance, after a file has been logically deleted from a TSM storage pool due to retention policies or version expiration, this command can be invoked to eliminate the corresponding metadata from the database.
Maintaining a streamlined database through the use of this function is crucial for optimizing TSM server performance. By removing obsolete entries, the system can more efficiently search and manage the remaining valid data. Historically, administrators would run this process regularly to prevent database bloat, which could lead to performance degradation and increased administrative overhead. The periodic execution of this operation contributes significantly to the overall health and responsiveness of the TSM environment.
