iCOD Features for nPartitions
HP’s iCOD Purchase and iCOD Utility products have some different
features and behaviors on nPartition servers than iCOD on other
non-partitionable systems.
The following list covers some of these unique features.
• iCOD on each nPartition is managed locally and independently.
iCOD commands affect and list iCOD settings for the local nPartition
(the nPartition where the commands are run).
While there is one iCOD license for the entire server complex, iCOD
processors are activated and deactivated independently for each
nPartition. Each nPartition has its own settings for iCOD contact,
notification, and processor configuration purposes.
• Passwords are not required for activating and deactivating iCOD
processor on nPartitions.
On nPartition servers under either iCOD contract (iCOD Purchase or
iCOD Utility) you can perform all tasks that change the iCOD
processor configuration for an nPartition.
On non-partitionable systems an HP service password is required for
some iCOD processor deactivation tasks.
• Both varieties of iCOD support “load balancing” processors across
nPartitions in the same server complex.
When using either iCOD Purchase or iCOD Utility, you can instantly
adjust each nPartition’s number of activated processors as system
loads demand and maintain the same total number of activated
processors in the complex.
For example, you can deactivate processors in one underused
nPartition and activate the same number of processors in another,
more heavily used nPartition to load balance using the same number
of processors.
This load balancing does not change any nPartition cell assignments.
Each nPartition keeps the hardware assigned to it while iCOD
software in each nPartition either activates or deactivates
processors.
