iCOD Cell Board

Chapter 9 107

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:

Step 1. Set the iCOD cell board’s use-on-next-boot flag to “y”

Step 2. 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).

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.

See “iCOD Cell Board Activation Fees” on page 104 for more details on

activating an iCOD cell board.
