Changing a running On/Off Capacity on Demand request

In a running On/Off Capacity on Demand (CoD) request, you can change the number of resources, number of days, or both the number of resources and number of days. You do not need to stop the current request to start a new request or wait until the current request expires.

Before you change a running On/Off CoD request, ensure that you understand the implications to billing. For more information, see Billing when changing a running On/Off Capacity on Demand request.

To successfully change a running On/Off CoD request:

If you are decreasing the amount of resources in the running request, return the On/Off CoD resources to be deactivated. See Returning On/Off Capacity on Demand resources for details about how to return On/Off CoD resources.
In the navigation area of the Hardware Management Console window, expand Systems Management.
Select Servers.
In the contents area, select the server on which you want to change your request.
Select Tasks.
Select Capacity on Demand.
Select either Processor or Memory.
Select On/Off CoD.
Select Manage.
Type the new number of On/Off CoD resources that you want and how many days you want them for and then click OK.

Any newly activated processors are now available for use by uncapped logical partitions. If there are no uncapped logical partitions, you must assign the processors to one or more logical partitions in order to begin using the processors. Any newly activated memory must be assigned to one or more logical partitions to begin using the newly activated memory.

If your server is in the manufacturing default configuration, the server can begin using the newly activated processors or memory immediately after restarting your server operating system. Alternatively, you can dynamically assign the newly activated processors or memory to the default partition.
