Activating Elastic Capacity on Demand
After you have ordered Elastic Capacity on Demand (CoD) and enabled Elastic CoD, you can request temporary activation of Elastic CoD resources.
- If you are using the HMC Classic or HMC Enhanced interface, use the HMC Capacity on Demand > Processor or Memory > On/Off CoD > Manage task.
- If you are using the HMC Enhanced+ interface, use the Capacity on Demand > CoD functions > Manage task.
Any newly activated processor cores are now available for use by uncapped logical partitions. If there are no uncapped logical partitions, you must assign the processor cores to one or more logical partitions in order to begin using the processor cores. Any newly activated memory must be assigned to one or more logical partitions to begin using the newly activated memory.
You can dynamically assign the newly activated processor cores or memory to the default partition. Alternatively, if your server is in the manufacturing default configuration, the server can start to use the newly activated processor cores or memory immediately after restarting your server operating system
You will be billed for the activated Elastic CoD resources regardless of whether they have been assigned to a logical partition or are being used. You can stop an active request for Elastic Capacity on Demand before it expires. For more information, see Stopping an Elastic Capacity on Demand request.
You can change a running Elastic CoD request. For more information, see Changing a running Elastic Capacity on Demand request. If you stopped the previous Elastic CoD request that was running on your server, and you start a new Elastic CoD request before the current resource day from the previous request expires (the hours remaining in the current resource day is a non-zero number), the new Elastic CoD request will be handled like a change request for billing purposes. For more information, see Billing when changing a running Elastic Capacity on Demand request.
To avoid being billed for unreturned processor or memory days, you must return the Elastic CoD resources before your Elastic CoD request expires. For more information, see Returning Elastic Capacity on Demand resources.
