Read this topic, to understand how to unlock the activation code interface.
Keying errors during the entry of the 34-character activation code are simply flagged and the interface remains functional for as many times as it takes for the activation code to be keyed correctly. However, if the activation code is keyed correctly but is invalid (Invalid means that the activation code is properly formed and entered correctly but is not for a valid CoD function or is not for the server on which it is being entered), the firmware permits only five entry attempts. On the first four attempts, if the activation code is refused as invalid, the HMC provides a warning message. On the fifth entry attempt, the HMC warns of the last entry attempt before the activation code entry interface is locked, and confirms whether you want to proceed. On the fifth entry of an invalid activation code, the HMC locks the code interface.
Refer to the table below for recovery options. Contact the CoD Admin for a valid CoD activation code for the invalid code.
|POWER5||Reboot the server to unlock the activation code entry interface.|
|POWER6®||Contact the CoD Admin for the reset code. Enter the reset code to unlock the activation code entry interface and reset the count of invalid codes entered. Note that the CoD activation codes do not interoperate with VET activation codes and no reset code will unlock the VET activation code entry interface. Therefore, for Power6 firmware, the only recovery option for a locked VET activation code entry interface is to reboot the server.|
|POWER7®||For POWER7 Release 2 firmware, both the CoD and VET activation code entry interfaces remain locked for approximately one hour. Wait for one hour. You do not need to reboot the server or enter a reset code to unlock the activation code entry interface.|

This topic explains other Capacity on Demand (CoD) Advanced Functions such as Enterprise Enablement, Active Memory™ Expansion, worldwide port name renewal, Live Partition Mobility Trial, activation for 256-core LPAR and Active Memory Mirroring for Hypervisor.
Enterprise Enablement is a Capacity on Demand Advanced Function technology that enables the system for 5250 online transaction processing (OLTP).
The following table describes the Enterprise Enablement features. Full-system Enterprise Enablement means that 100% of the processor cores are enabled.
|Machine type and model||Single-processor enterprise enablement||Full-system enterprise enablement|
|8231-E1C and 8231-E2C||4970||4974|
|8231-E1D, 8231-E2D, and 8268-E1D||4970||4974|
Active Memory Expansion (AME) is a POWER7® function available for use in AIX® partitions (AIX 6.1 or later with Technology Level 4).
With AME, memory can be expanded beyond the physical limits of the server or of the true physical memory assigned to the AIX partition by using compression and decompression of memory content.
Depending on your data's characteristics and the available processor resource, you might see expansion up to 100% of the true memory that can allow your partition to do more work, or allow your server to run more partitions and do more work, or both. After Active Memory Expansion is enabled on the server, you control which AIX partitions use Active Memory Expansion and control the degree of expansion.
You can evaluate the use of Active Memory Expansion at no charge with Trial Capacity on Demand (Trial CoD). With Trial CoD, the Active Memory Expansion function can be temporarily activated for up to 60 days at no charge. Trial Active Memory Expansion is available once per server and it allows you to validate the benefits your POWER7 server can realize.
Complete the following steps to order Trial Active Memory Expansion:
|Machine type and model||Active Memory Expansion feature|
|8231-E1C and 8231-E2C||4795|
|8231-E1D and 8231-E2D||4795|
A worldwide port name (WWPN) is a unique 64-bit identifier that is assigned to a fibre channel node port, called an N_port. The storage area network (SAN) administrator assigns storage to a WWPN. This scheme provides security that limits access to storage on the SAN. The fibre channel standards allow N_Port virtualization, called NPIV, so that one N_port can be shared and require the generation of a unique worldwide port name for each NPIV. Each IBM® server that supports NPIV provides up to 64,000 unique WWPNs. When a server indicates that there are no WWPNs remaining, customers must request a WWPN renewal code on the website. The code enables a WWPN prefix, which provides the first 48 bits of each WWPN and makes 64,000 more WWPNs available on the server.
The Live Partition Mobility feature enables live partitions in servers with no application downtime, resulting in better system utilization, improved application availability, and energy savings. You can use the Live Partition Mobility Trial version to evaluate Live Partition Mobility free of charge for a period of 60 days. After the trial period of 60 days, if you want to continue to use Live Partition Mobility, you can order the PowerVM® Enterprise Edition. If you do not upgrade to PowerVM Enterprise Edition, at the end of the trial period, your system automatically returns to PowerVM Standard Edition.

The activation for 256 core LPAR feature permanently enables greater than 128 cores and up to 256 cores per dedicated processor partition on the 9119-FHB POWER7 servers. Without this feature, the largest partition that can be created is up to 128 cores. Micropartitions, which are not affected by this feature, can only be created with a maximum of 128 virtual processors.
|Machine||Activation for 256-core LPAR|
Active Memory Mirroring for hypervisor is designed to ensure that system operation continues even in the unlikely event of an uncorrectable error occurring in main memory used by the system hypervisor. The feature permanently activates the Active Memory Mirroring for hypervisor capability on the 9179-MHC POWER7 servers. When this feature is activated, two identical copies of the system hypervisor are maintained in memory at all times. Both copies are simultaneously updated with any changes. In the event of a memory failure on the primary copy, the second copy is automatically called, eliminating platform outages due to uncorrectable errors in system hypervisor memory.

You can view and save PowerVM® Editions code-generation information using the Hardware Management Console (HMC). You might need to do this if the PowerVM Editions code that was provided for your server does not work.
You can view PowerVM Editions code-generation information, and then save it to a file on a remote system or to a file on removable media. The information used to generate your PowerVM Editions codes must exactly match the information shown on the HMC PowerVM Editions Code Information window. To update the information that is used to generate your PowerVM Editions codes, use the PowerVM Editions Code Information window to save the PowerVM Editions code information to a file on a remote system or to a file on removable media. Then, you can either attach the file to an email, or print the file and fax it to your Capacity on Demand (CoD) administrator.
To view and save PowerVM Editions code-generation information, do the following:

To fax or send an email with the PowerVM Editions code information in it to your PowerVM Editions or CoD administrator, use one of these options to send your information:
You can see what PowerVM® Editions technologies activations are entered and what capabilities have been enabled on your server by using the history log.
