iCOD Requirements for nPartition Servers

HP’s iCOD software has the following requirements and restrictions for

using and managing iCOD processors in an nPartition server complex.

• Each nPartition server complex can optionally be under either an

iCOD Purchase contract or a pay per use (iCOD Utility) contract.

In a server complex that is under one of these contracts, the

appropriate software must be installed in the complex’s nPartitions

to support the contract.

HP does not support mixing iCOD Purchase and iCOD Utility

nPartitions in the same server complex.

• nPartition servers that are under an iCOD Utility contract (a pay per

use “PPU” contract) must have iCOD Utility software installed and

running on every HP-UX instance in the complex.

NOTE Where multiple devices are conﬁgured for an nPartition (for

example, the PRI, HAA, and ALT boot paths), each device must have

iCOD Utility software installed. This applies to nPartition servers

under a PPU (iCOD Utility) contract.

• Each nPartition that is under an iCOD Purchase contract must have

iCOD Purchase software installed to enable additional processors to

be activated (or to deactivate processors).

In an iCOD Purchase complex, you do not have to install iCOD

Purchase software on the nPartitions that are not under an iCOD

Purchase contract. However, in this situation HP recommends that

all nPartitions have iCOD Purchase software installed to allow

administrators to perform “load balancing” across nPartitions.

NOTE All potential boot disks for nPartitions with iCOD processors must

have the iCOD Purchase software installed, including any alternate

boot devices. This applies to nPartition servers under an iCOD

Purchase contract.
