Overview of Volume Migration
Volume Migration is used to optimize your data storage by balancing resource utilization and resolving bottlenecks of system activity on the storage system. If heavy input/output (I/O) activity occurs on a specific data drive or disk processor, the host might suffer from slower response times. To avoid this situation, Volume Migration lets you migrate high-usage volumes to a low-usage data drive or a fast data drive.
Migrating volumes with Volume Migration is completely non-disruptive as the data being migrated can remain online to all hosts for read and write operations throughout the entire migration process.
The system administrator specifies the source volume and the target volume, and then executes the migration plan.
