IBM z13s Technical Guide
As part of the setup, the customer provides 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 is beneficial by enabling 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 server for processors or memory. Requesting a customer order
approval to conform to your operation policies is possible. You can enable the definition of
additional IDs to be authorized to access the CIU. Extra IDs can be authorized to enter or
approve CIU orders, or only view existing orders.
Permanent upgrades
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 MCI, up to the limits of the installed CPC
drawers on an existing z13s CPC.
Temporary upgrades
The z13s base model describes permanent and dormant capacity (Figure 8-1) using the
capacity marker and the number of PU features installed on the CPC. Up to eight temporary
offerings (or records) can be present.
Each offering has its own policies and controls, and each offering can be activated or
deactivated independently in any sequence and combination. Although multiple offerings can
be active at any time if enough resources are available to fulfill the offering specifications, only
one On/Off CoD offering can be active at any time.
