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.
Migration types space management client provides automatic and selective migration. Automatic migration is triggered by space-usage thresholds (threshold migration) or an out-of-space condition (demand migration). File migration eligibility File premigration space management client prepares files for automatic migration by using a process that is called premigration . Automatic file migration space management client monitors space usage and automatically migrates files whenever it is necessary. Files are prioritized for automatic migration based on the age and size settings. The dsmscoutd daemon searches these files in cycles and upon request from automatic migration.Selective file migration Migration of a single file system to two or more IBM Storage Protect servers
