zSeries 990 Technical Guide
When the customer disposes of the server, or decides that they want to disable future On/Off
CoD, the customer is required to apply a termination feature that disables the right to use.
Initiation
Before a customer can order temporary capacity, they must have a signed agreement for the
Customer Initiated Upgrade (CIU) facility. In addition to this agreement, they will need to
acknowledge and agree to additional specific terms that govern the use of temporary
capacity. At the completion of signing a contract, an order is placed through CIU to install an
On/Off CoD right to use feature. This feature cannot be installed if CBU is already active on
the z990 server. Once installed, the customer is free to order and activate temporary
capacity.
Ordering
Typically, On/Off CoD can only be ordered through CIU; however, there will be an RPQ
available for customers who do not have an Remote Support Facility (RSF) connection.
If an order is attempted prior to establishing the right to use, or if the configuration has no
permanent CPs, that order will not be processed. Similar to a permanent upgrade, the
customer will order one to n CPs, ICFs, IFLs, and/or zAAPs worth of temporary capacity. A
LIC record is established and staged to RETAIN® for this order, where it remains available for
30 days. This record, once activated, has no expiration date; however, an individual record
can only be activated once. Subsequent sessions will require a new order to be generated
producing a new LIC record for that specific order.
Figure 8-9 on page 205 shows a Resource Link Web page that displays an On/Off CoD order
example.
