Performing resource management

Learn about the final steps you need to perform after you add, replace, or remove a hardware feature. Also, understand why you need to complete resource-management tasks.

After you change a hardware feature, you might need to perform the following tasks:

  1. If your server is partitioned, assign resources to logical partitions as necessary. For information about assigning resources to a logical partition, see .Perform dynamic movement of resources.
  2. If you changed the disk configuration, perform disk-unit management for the following reasons:
    • To protect data when using RAID or mirroring.
    • To configure the disks on your server.

    To perform disk management, you can use the Work with Disk Units option from the Dedicated Service Tools display. See Work with disk units.

    Note: After you complete your disk configuration, you can remove or reassign disk units using dedicated service tools (DST). For information, see Moving and removing disk units.

    Disk units that you remove from the configuration need to also be physically removed to prevent them from being added back into the configuration when you restart the server.

  3. Update the hardware resource names of workstations, communications, removable media, Local Area Network (LAN), Wide Area Network (WAN), or Integrated xSeries® Server (IXS) as necessary. For information about changing hardware resource names, see Correcting hardware resource names after an upgrade.
  4. If you changed the console type, perform the IPL and resource management tasks in Completing server configuration.
  5. If you made changes to enable clusters or independent disk pools, ensure that they are created and configured correctly, using the information in the Configure a cluster and Configure independent disk pools topics.
