Tivoli Space Manager for UNIX Using the Hierarchical Storage Management Clients

Start Threshold Migration Manually

The space monitor daemon monitors space usage on all file systems for which space management is active. Threshold migration starts automatically to reduce space usage to the low threshold that you set if space usage equals or exceeds the high threshold that you set.

To reduce space usage to the low threshold on your file system before it reaches the high threshold, start threshold migration manually. If space usage exceeds the low threshold that you set for your file system when you start threshold migration manually, eligible files migrate until space usage drops to the low threshold.

To start threshold migration manually for one or more file systems, follow these steps:

  1. Click Space Manager in the Hierarchical Storage Management window.
  2. Click the file systems that you want to select for threshold migration. A window displays for each file system.
  3. Select the window that you want to view.
  4. Click Selected>Start Threshold Migration. The Threshold Migration Status window displays.
  5. Click Stop in the Threshold Migration Status window to stop the migration process. Any files that migrated successfully remain in a migrated state.
  6. Click Close to close the Threshold Migration Status window.

If additional files are eligible for migration and you did not exceed the premigration percentage that you set for your file system, additional files premigrate after the threshold migration process completes. The status of the premigration process displays in the Threshold Migration Status window.

Start Migration With the dsmautomig Command

To start threshold migration from the command line, use the dsmautomig command. For example, to start threshold migration for the /home file system, enter:

   dsmautomig /home

To display information about your migrated files, use the -detail parameter with the dsmautomig command.

See dsmautomig for more information about this command.
