Managing iCOD Utility (Pay Per Use)

on nPartitions

This section describes several methods of managing processor resources

for a server complex that is under a pay per use (iCOD Utility) contract.

If your server complex is under an iCOD Utility contract then you are

billed for all activated processors in the whole nPartition server complex.

The pay per use iCOD Utility contract enables you to manage processor

resources in the complex in such a way that you only pay for the amount

of processor resources that you actually require.

When you have processors in an nPartition complex that you do not need,

you can exclude those processors from billing by deactivating processors,

by making processors inactive, or by deconﬁguring processors.

These three methods of excluding processors from pay per use billing are

discussed here. See the Deactivated Processors, Inactive Processors, and

Deconﬁgured Processors sections that follow.

Tips for Pay Per Use Processor Management

• The recommended method for activating and deactivating processors

on nPartitions is to use the icod_modify command. This command

instantly increases or decreases the number of available processor

resources in the nPartition without requiring a reboot.

For example, if an nPartition is underused—as when most of the

nPartition’s processors are constantly idle—you could deactivate

unneeded processors by using the icod_modify -d... command.

• When an entire nPartition in a complex is unused you can exclude

that nPartition’s processors from billing by making the nPartition

inactive.

For example, if an nPartition is not running HP-UX but is “just

sitting at the BCH interface” you could reset the nPartition to the

ready for reconﬁg state by using the BCH RECONFIGRESET command

to make the nPartition inactive. (When an nPartition is running

HP-UX, using the shutdown -R -H command makes the nPartition

inactive.)
