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 nPar 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 nPar 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 nPars is to use the icod_modify command. This command
instantly increases or decreases the number of available processor
resources in the nPar without requiring a reboot.
For example, if an nPar is underused—as when most of the nPar’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 nPar’s processors from billing by making the nPar inactive.
For example, if an nPartition is not running HP-UX but is “just
sitting at the BCH interface” you could reset the nPar to a
ready for reconfig state by using the BCH RECONFIGRESET command
to make the nPar inactive. (When an nPar is running HP-UX, using
the shutdown -R -H command makes the nPar inactive.)
