Technical Changes for Version 5 Release 1--March 2002

The following changes have been made to the product for this edition:

Moving Data by Node
You can use the MOVE NODEDATA command to move data in a sequential-access storage pool for one or more nodes, or move selected file spaces for a single node. You can also use MOVE NODEDATA to move data to another storage pool.

See Chapter 7, Managing Storage Pools and Volumes.
