    If you migrate an existing non-striped volume to the same extent pool with a rotate extents allocation method, then the volume is "reorganized." If you add more ranks to an existing extent pool, then the "reorganizing" existing striped volumes spreads them across both existing and new ranks. You can configure and manage storage pool striping using the DS Storage Manager, and DS CLI, and DS Open API.

    You can complete these activities and then activate the function. Activation refers to the retrieval and installation of the feature activation code into the storage system. The feature activation code is obtained by using the IBM Data storage feature activation (DSFA) website (www.ibm.com/storage/dsfa) and is based on the license scope and license value.

  • Page 202: Activation Of Licensed Functions

    If the capacity is exceeded, IBM is notified that the usage exceeds the allowed capacity on any given licensed function. You are notified by IBM and required to extend enablement of your licensed function and install a new licensed feature key.
