IBM Tivoli Storage Manager, Version 7.1

MOVE NODEDATA (Move data by node in a sequential access storage pool)

Use this command to move data that is in a sequential-access storage pool. You can move data for one or more nodes, a group of file spaces, or for a group of collocated nodes. You can also move selected file spaces for a single node. The data can be in a primary storage pool, a copy storage pool, or an active-data pool.

This command is helpful for reducing the number of volume mounts during client restore or retrieve operations by consolidating data for a specific node within a storage pool, or to move data to another storage pool. For example, you can use this command for moving data to a random-access storage pool in preparation for client restore processing.

Ensure that the access mode of the volumes from which you are moving the node data is read/write or read-only and that the access mode of the volumes to which you are moving the node data is set to read/write. This operation will not move data on volumes with access modes of offsite, unavailable, or destroyed.

The MOVE NODEDATA command takes two forms, depending on whether you are moving data only for selected filespaces. The syntax and parameters for each form are defined separately.

Restriction: You cannot move node data into or out of a storage pool that is defined with a CENTERA device class.
