CIU prerequisites CIU registration and contract for CIU Permanent upgrades Temporary upgrades Chapter 8. System upgrades  325 The CIU facility supports LICCC upgrades only. It does not support I/O upgrades. All other  capacity that is required for an upgrade must be previously installed. Extra processor drawers  or I/O cards cannot be installed as part of an order that is placed through the CIU facility. The  sum of CPs, unassigned CPs, ICFs, zIIPs, IFLs, and unassigned IFLs cannot exceed the  client (characterized) PU count of the installed processor drawers. The total number of zIIPs  can be twice the number of purchased CPs. To use the CIU facility, a client must be registered and the system must be set up. After you  complete the CIU registration, access to the CIU application is available through the IBM  Resource Link website. As part of the setup, provide one resource link ID for configuring and placing CIU orders and,  if required, a second ID as an approver. The IDs are then set up for access to the CIU  support. The CIU facility allows upgrades to be ordered and delivered much faster than  through the regular MES process. To order and activate the upgrade, log on to the IBM Resource Link website and start the CIU  application to upgrade a system for processors or memory. You can request a client order  approval to conform to your operational policies. You also can allow the definition of more IDs  to be authorized to access the CIU. More IDs can be authorized to enter or approve CIU  orders, or only view orders. Permanent upgrades can be ordered by using the CIU facility. Through the CIU facility, you  can generate online permanent upgrade orders to concurrently add processors (CPs, ICFs,  zIIPs, IFLs, and SAPs) and memory, or change the model capacity identifier. You can do so  up to the limits of the installed processor drawers on a system. The base model z14 server describes permanent and dormant capacity by using the capacity  marker and the number of PU features that are installed on the system. Up to eight temporary  offerings can be present. Each offering includes its own policies and controls, and each can  be activated or deactivated independently in any sequence and combination. Although  multiple offerings can be active at any time, only one On/Off CoD offering can be active at any  time if enough resources are available to fulfill the offering specifications. Temporary upgrades are represented in the system by a  record . All temporary upgrade  records are on the SE hard disk drive (HDD). The records can be downloaded from the RSF  or installed from portable media. At the time of activation, you can control everything locally.
