After you change a hardware feature, you may need to perform the following tasks:
For information about assigning resources to a partition, see Perform dynamic movement of resources.
To do this, you can use the Work with Disk Units option from the Dedicated Service Tools display. To learn how, see Chapter 18. "Procedures for Configuring Disks and Disk Protection" of the Backup and Recovery Guide.
Disk units that you remove from the configuration should also be physically removed to prevent them from being added back into the configuration during an IPL.
For information about changing hardware resource names, see the Fix hardware resource names after an upgrade topic.
