IBM 890 instruction

IFL or ICF is installed on the permanent machine with the restrictions that a) additional engines, of each type, cannot exceed the number of installed permanent engines of that same type and b) adding engines cannot exceed the physical limit of the installed machine.

The maximum number of On/Off CoD zAAPs available for z890 cannot exceed the number of zAAPs, with the addi- tional restriction that the sum of zAAPs and On/Off CoD zAAPs cannot exceed the number of CPs.

For example, capacity setting 110 is eligible for On/Off CoD upgrades to only capacity settings 120 and 210. All other target capacity settings would result in more than two times the base capacity.

You will be billed for associated usage through one or more of the following features: On/Off CoD Active CP-Day (#9897), On/Off CoD Active IFL Day (#9888), On/Off Active ICF-Day (#9889), or On/Off CoD Active zAAP-Day (#9893).

You will be billed for each On/Off CoD Active engine turned on in any given 24-hour period, continuing until such On/Off CoD Active engine is turned off. Each month your bill will be calculated for the sum of all orders installed within the prior month. Monitoring will occur through the server call home facility and a bill will be gen- erated if the hardware capacity has been enabled for any given month. You will continue to be billed for the use of temporary capacity until you return the server to its original state. After concurrently returning to the original state, you may choose to activate a new On/Off CoD upgrade, which can be different from the previous upgrade. When you dispose of the server, or decide that you want to disable future temporary upgrades, you are required to remove the enablement feature, On/Off CoD Enablement (#9896).

Although the hardware upgrade does not need a POR/ IML if there is a change in engine size, a z/OS IPL will be required.

On/Off CoD is delivered through the Customer Initiated Upgrade (CIU) facility. To participate in this offering, customers must install CIU Enablement and On/Off CoD Enablement, and must agree to speciﬁ c terms and condi- tions which govern the use of temporary capacity.

For z890, you may request and concurrently install tem- porary capacity through the CIU application on Resource Link™, and use that additional capacity for as long as needed. Using this facility, you may increase a machine’s capacity setting and add a quantity of temporary IFLs and ICFs, up to the machine’s current capacity setting or the number of IFLs and ICFs, respectively, on the same machine. You may similarly request and concurrently install a quantity of temporary zAAPs up to the quantity of permanent zAAPs, with the limitation that the combined quantity of temporary zAAPs plus permanent zAAPs may not exceed the combined quantity of temporary CPs plus permanent CPs. You will be billed for associated usage through one or more of the following features: On/Off CoD Use Days, (one of #6121 through #6471), On/Off CoD Active IFL-Day (#9888), On/Off Active ICF-Day (#9889), or On/Off CoD Active zAAP-Days (#9893).

Typically, On/Off Capacity on Demand will be ordered through CIU, however there will be an RPQ available if no RSF connection is present.
