For further information about activating and deactivating On/Off Capacity on Demand on your system, refer
to “Activation Process for CUoD Features” on page 13, or refer to the
IBM Hardware Management Console
for pSeries Installation and Operations Guide that was delivered with your hardware management console.
Trial Capacity on Demand
Trial Capacity on Demand enables CUoD features to be activated one time for a period of 30 consecutive
days. If your system was ordered with CUoD features and they have not yet been activated, you can turn
the features on for a one-time trial period. With the trial capability, you can gauge how much capacity you
might need in the future, if you decide to permanently activate the resources you need.
Alternatively, the Trial Capacity on Demand function can be used to immediately activate resources while
processing an order for a permanent activation code.
For further information about using Trial Capacity on Demand, refer to “Activation Process for CUoD
Features” on page 13, or refer to the
IBM Hardware Management Console for pSeries Installation and
Operations Guide that was delivered with your hardware management console.
Capacity Planning
If you are doing capacity planning for models with CUoD features, plan ahead for any potentially disruptive
actions that might inhibit your using fully the capacity of the system. Some actions you may want to take
prior to activating any CUoD features are as follows:
v Perform any I/O updates, such as adding adapters necessary to increase system capacity
v
Perform memory upgrades (CUoD) or standard memory features
v Prepare logical partitions
By planning ahead, you can accommodate the growth of existing workloads, as well as handle new
workloads without requiring a server outage. Each component of a server affects performance and overall
throughput of workloads. By planning ahead and taking into account the complete server configuration,
you can help ensure that you get the full benefit of CUoD activations.
Note: If you have questions about capacity-planning topics not covered here, contact your sales
representative for assistance.
Processor CUoD Ordering
Permanent CUoD capacity can be activated in either one of the following scenarios. The description of
each scenario indicates if and when it is necessary to send vital product data (VPD) to IBM.
v
New system order (new footprint): An order can contain a number of CUoD-activation features. The
manufacturing facility fills orders directly at the plant of manufacture, before the server is delivered to
the customer.
v Ordering activation features for an installed server: After you have determined that you want to
permanently activate some or all of your CUoD features, contact your business partner or sales
representative to place an order.
When the order record and the VPD are both available to the manufacturing facility, a processor CUoD
activation code unique to your server is generated. The activation code is mailed to you and posted at
http://www.ibm.com/servers/eserver/pseries/cuod/index.html.
As part of the order process, VPD collected from the installed server is combined with information from
the order records for CUoD activation features. This combined information is used to generate a CUoD
activation code specifically for your server, enabling the activation of the appropriate features. Allow
some time for the order processing and posting of the processor on demand activation code to take
place. Then use the code to activate the processor on demand features directly on your server.
If you need to activate resources immediately, you can activate features using the Trial Capacity on
Demand function. This allows you to use the resources immediately while the permanent activation
code is being processed.
