Managing space for AIX and Linux systems

The space management client provides hierarchical storage management (HSM) for AIX® and Linux™ systems and storage pools.

Configuring the space management client
Before you configure space management for a file system, you must configure the space management client itself. You also must configure some options that apply to all space-managed file systems.
Adding and configuring space management for a file system
When you add space management to a file system, you indicate how and when files are migrated and recalled. You can also deactivate, reactivate, and remove space management from a file system.
Migrating files
There are several types of file migration. You can configure the space management client to migrate files when a files system is low on free space, or you can selectively migrate files at any time. A file must meet several criteria to be eligible for selective or automatic migration.
Backup and restore on space managed file systems
Coordinate backup and migration to protect the file system data.
Recalling migrated files
A migrated file is recalled to the file system automatically when the file is accessed. You can also recall selected files without accessing the files.
File system reconciliation
To keep local file systems synchronized with the IBM Storage® Protect server for space management services, the space management client automatically reconciles your file systems at preset intervals. You can also start reconciliation manually, and you can configure immediate reconciliation.
Space management daemons
The space management client uses the space monitor, recall, scout, and watch daemons to manage file systems automatically.
Scheduled HSM service
IBM Storage® Protect provides a service to schedule backup, archive, and space management tasks.
