iCOD Cell Board

Overview

iCOD Cell Board offers you a way to have additional (inactive) cell board capacity in your iCOD system for growing business needs. When the need arises, these iCOD cell boards, which contain memory and processors, are then available for instant activation and use.

Similar to the iCOD CPU program, there is an initial right to access fee for an iCOD cell board. Once activated, a cell board and its memory are considered purchased and you must pay the enablement fee to purchase the cell board.

After an iCOD cell board has been activated, all of the iCOD processors on the cell board are available for purchase accordingly. That is, you can activate an iCOD processor and purchase it by paying the enablement fee.

As part of the activation process, you should submit a Purchase Order to HP to purchase the cell board, memory, and any activated processor(s).




	IMPORTANT: An active cell board must have a minimum of one active processor.

Ordering a New System Containing iCOD Cell Board

Initially, you have the right to access an iCOD cell board by ordering the appropriate HP product number, for your specific class of HP server. Additionally, the memory on the iCOD cell board has a separate HP product number for the right to access.




	NOTE: It is highly recommended to have the same number of processors and amount of memory on all cell boards in a given hard partition (nPartition). For optimum performance, each nPartition should have cell boards with identical numbers of processors and amounts of memory (otherwise, the system performance can be unpredictable).

When you decide to activate the iCOD cell board and memory, you order the corresponding HP product numbers, and pay the enablement fee.

If the cell board activation results in any iCOD processors being activated, those activated processors need to be purchased using the existing HP iCOD CPU product numbers.

Rules for ordering memory ensure that the iCOD cell board matches the amount of memory in the non-iCOD cell boards, in a given nPartition.

HP-UX License and Support

You do not initially pay for HP-UX license and support fees on an iCOD cell board.

When you activate an iCOD cell board, and pay for the enablement fee, you must additionally pay for the incremental HP-UX license and support costs for each iCOD processor that is activated. That is, the HP-UX license and support costs are based on a “per active processor” basis and not included in the enablement fee for the iCOD cell board.

If activation of an iCOD cell board does not increase the number of active processors, then you do not have to pay any incremental HP-UX license and support fees.

Your iCOD system must be properly licensed for the HP-UX Operating Environment (OE) when activating the iCOD cell board. Software licenses for 3rd party software may also be needed. Check with your application software vendor for licensing requirements.

iCOD Cell Board Activation Fees

Additional fees are payable to HP when you activate an iCOD cell board. Contact your HP sales representative for details.

Activating an iCOD cell board causes at least one processor to become active on that cell board. However, this does not necessarily mean an iCOD processor has been activated or that the total number of active processors increases — unless the requirement of a minimum of one active processor per active cell board could not be met without activating a new processor. In summary, if the number of activated (and purchased) processors in a nPartition equals (or exceeds) the number of active cell boards, then the iCOD software does not automatically activate additional iCOD processors.




	NOTE: The following examples assume that the number of requested active processors has not been increased just prior to the iCOD cell board activation.

Example 9-1 Activating an iCOD Cell Board without increasing the number of total active processors

For example, if you have a two cell board nPartition with four active processors on one cell board, and an inactive (iCOD) cell board with four iCOD processors, activating the iCOD cell board results in two active processors per cell board. That is, the iCOD software distributes the number of active processors across the two cell boards. The total number of active processors has not changed, so no payment for processors is due.

Table 9-2 Activation Fees — No Increase in Active Processors

State	Non-iCOD Cell Board Processors	iCOD Cell Board Processors	HP Activation Fees
Before iCOD Cell Board Activation	4 active, 0 iCOD	4 iCOD	N/A
After iCOD Cell Board Activation	2 active, 2 iCOD	2 active, 2 iCOD	Enablement fee for activated iCOD cell board (No processor activation charges because the number of total active processors did not increase)

Example 9-2 Activating an iCOD Cell Board and increasing the number of total active processors

In a different scenario, activation of an iCOD cell board can cause the number of requested active processors to be below the minimum required (one active processor per cell board) and necessitate the purchase of the newly activated iCOD processor. For example, if you have a two cell board nPartition with one active processor on one cell board and three iCOD processors, and an inactive (iCOD) cell board with four iCOD processors, activating the iCOD cell board results in one active processor per cell board. That is, the iCOD software distributes the number of active processors across the two cell boards. The total number of active processors has increased by one and payment for the processor enablement fee is due.

State	Non-iCOD Cell Board Processors	iCOD Cell Board Processors	HP Activation Fees
Before iCOD Cell Board Activation	1 active, 3 iCOD	4 iCOD	N/A
After iCOD Cell Board Activation	1 active, 3 iCOD	1 active, 3 iCOD	Enablement fee for activated iCOD cell board Enablement fee for activated iCOD processor HP-UX license and support fees for activated iCOD processor

Activation of an iCOD Cell Board

An iCOD cell board is configured so that it is assigned to a nPartition; however, it does not participate in the boot of the nPartition. Activating an iCOD cell board is a two step process:

Set the iCOD cell board’s use-on-next-boot flag to “y”
Perform a reboot of the nPartition

Example 9-3 Activating an iCOD cell board in cabinet 0, slot 5, nPartition 3

For example, changing the use-on-next-boot flag to “y” on the iCOD cell board in cabinet 0, slot 5, in nPartition 3 can be accomplished via the following command:

/usr/sbin/parmodify -p 3 -m 0/5::y:

See the HP System Partitions Guide for details about adding and configuring cells in nPartitions.

After you have set the iCOD cell board’s use-on-next-boot flag to “y”, and performed the reboot, you can use the icod_modify command to activate iCOD processors that are listed as inactive processors that can be activated (as reported by the icod_stat command).

The number of active processors in the nPartition remain the same after the iCOD cell board is made active — unless prior to the iCOD cell board’s activation the number of requested active processors is greater than the number of active processors (as reported by the icod_stat command).

See “iCOD Cell Board Activation Fees” for more details on activating an iCOD cell board.

Accidental Activation of an iCOD Cell Board

If you inadvertently activate an iCOD cell board, you can de-activate it by following this two step procedure:

Set the iCOD cell board’s use-on-next-boot flag to “n”
Perform a reboot of the nPartition




	IMPORTANT: You must deactivate the inadvertently activated cell board within five days or the cell board is considered to be purchased from HP.

Example 9-4 Deactivating an iCOD cell board in cabinet 0, slot 5, nPartition 3

For example, changing the use-on-next-boot flag to “n” on the iCOD cell board in cabinet 0, slot 5, in nPartition 3 can be accomplished via the following command:

/usr/sbin/parmodify -p 3 -m 0/5::n:

The “n” in the above command line sets the cell board’s use-on-next-boot flag to “no” and causes the cell board to not participate in the nPartition when it is booted.
