To maintain free space in primary storage pools, you can set capacity thresholds so that
data automatically migrates to the next primary storage pool in the hierarchy. If an automated
migration fails, you can manually start migration from the Operations Center.
About this task
The storage pool migration action moves data from a primary storage pool that you select to the next storage pool in the storage hierarchy.Restriction: The storage pool migration action applies only to volume-based storage pools. You cannot migrate data from container storage pools, which use additional file system space or cloud storage space as needed. To move data from a volume-based pool to a directory-container pool or cloud-container pool, use the Convert action.
