Processor on Demand Activation Features
Standby processors (two or more) can be permanently activated by ordering a quantity
of permanent processor on demand activation features. This order is filled when your
service provider receives your request, generates an activation code, and delivers it to
you. Activation codes can be delivered to you through postal mail and they are posted
on the Web.
Capacity Planning
If you are doing capacity planning for models offering processor on demand, plan
ahead for any potentially disruptive actions that might inhibit your using fully the
capacity of the activated processors. Some actions you may want to take prior to
activating any processor on demand features are as follows:
v Perform any I/O updates, such as adding adapters necessary to increase system
capacity
v Perform memory upgrades
v Prepare LPAR partitions
By planning ahead, you can accommodate the growth of existing workloads, as well as
handle new workloads without requiring a server outage. Other components of a server
such as memory and I/O affect 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 processor on demand activations.
Note: If you have questions about capacity-planning topics not covered here, contact
your sales representative for assistance.
Processor on Demand Ordering
Permanent processor-on-demand capacity can be activated in either of the following
scenarios. The description of each of the following scenarios highlights 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 processor on
demand 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 standby processors,
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 on demand activation code unique to your server is generated. The
activation code is mailed to you and posted at a public Web site for quick access:

As part of the order process, VPD collected from the installed server is combined
with information from the actual order records for processor on demand activation
features. This combined information is used to generate a processor on demand
activation code specifically for your server, enabling the activation of the desired
number of standby processors. Allow some time for the order processing and posting
