Stopping Trial Capacity on Demand

Trial Capacity on Demand ends when the trial period is over and the resources have been reclaimed by the server. You must return the resources before the trial period has ended.

For more information about returning CoD resources, see Returning Capacity on Demand resources. If your server is powered off or loses power before the resources are removed from the logical partitions, you might need to perform recovery actions to successfully power on your server. For more information, see Recovery actions.

Trial Capacity on Demand can also end when you enter a Capacity Upgrade on Demand activation code to permanently activate the processors or memory. For more information about permanently activating resources, see Activating Capacity Upgrade on Demand. For more information about Capacity Upgrade on Demand, see Capacity Upgrade on Demand.

Stopping a current trial

You can use the HMC to stop a current Capacity on Demand trial for processors or memory units before the trial automatically expires. If you choose to stop the trial before it expires, you cannot restart it and you forfeit any remaining days.

Additional requests for Trial Capacity on Demand might be available from your Capacity on Demand administrator.

To stop a current Trial Capacity on Demand, follow these steps:

Return the trial resources. See Returning Capacity on Demand resources for more information.
In the navigation area of the HMC window, expand Systems Management.
Select Servers.
In the contents area, select the server on which you want to stop Trial Capacity on Demand.
Select Tasks.
Select Capacity on Demand (CoD).
Select either Processor or Memory.
Select Trial CoD.
Select Stop.
In the confirmation window, click Yes to stop the trial. Click No to cancel the request to stop the trial (the trial will remain active).

Trial Capacity on Demand is now stopped and cannot be restarted.

Recovery actions

Perform these recovery actions in the event the server is powered off or loses power when there are unreturned Trial CoD or On/Off CoD resources. Unreturned Trial CoD resources result when the trial period ends before the Trial CoD resources have been removed from your logical partition. Unreturned On/Off CoD resources result when the On/Off CoD request expires before the On/Off CoD resources have been removed from your logical partition. These recovery actions need to be used to ensure that logical partitions that were running prior to the power off or loss of power are successfully powered on.

When a server is powered off or loses power, all unreturned Trial CoD or On/Off CoD resources are reclaimed by the server. As a result, when the server is powered back on, all logical partitions that were running prior to the power off or loss of power might not be able to be restarted since only licensed resources are available for use. Furthermore, when a logical partition is powered on, if there are not enough licensed resources to satisfy the logical partition's memory or processor requirements, the power on of that logical partition will fail. The failure might result in an HMC message of HSCL03F4 (not enough processing resources to meet the allocation setting), or a system reference code of B2xx1150 or B2xx1230.

Note: The server can power on to standby mode only if you have specified that option prior to powering on your server.

To successfully power on those logical partitions, perform either step 1 or 2, or a combination of the 2 steps.

Reduce logical partition resources so that the total of logical partition resources across all logical partitions to be powered on does not exceed the total number of activated resources.
Enter new Capacity on Demand activation codes to satisfy these requirements. Additionally, start an On/Off CoD request (if On/Off CoD is still enabled) or enter a new Trial CoD activation code. If the On/Off CoD enablement is exhausted, a new On/Off CoD enablement code would need to be entered before doing a new On/Off CoD request.
