Processor Instant Capacity on Demand (iCOD)
Procedures for Changing Processor iCOD Configurations on nPartitions
HP System Partitions Guide: Administration for nPartitions, rev 5.1 414
You can activate or deactivate processors in only the local nPartition (the
nPartition in which you issue the icod_modify command).
Step 2. Issue the icod_modify -s... command and specify the number of
processors to be activated.
You must include the following details after the -s option. This
information is recorded in the nPartition’s iCOD change log.
[ description ]: user_name : mgr_name : mgr_email : mgr_phone
For example, the following command sets the number of “requested
active processors” to 10, which may increase or decrease the number of
activated processors in the nPartition (depending on the number of
processors available before the command is issued).
# icod_modify -s 10 "activate 10 CPUs total":Ann:Joe:[e-mail]:555-5555
See also the icod_modify (1M) manpage for details.
Step 3. As desired, issue the icod_stat command to list the new processor
configuration details for the local nPartition.
Load Balancing Processors across nPartitions with iCOD
This procedure (using both the icod_modify -d... and
icod_modify -a... commands) adjusts the balance of activated
processors across two nPartitions in the same server complex: deactivate
processors in one nPartition and activate the same number of processors
in another nPartition.
NOTE After “load balancing” processors across nPartitions, each nPartition still
has the same cells and processors assigned to it.
However, this procedure reduces the number of activated processors in
the first nPartition and increases (by the same amount) the number of
activated processors in the second nPartition.
This procedure does not affect your billing for iCOD services if: the total
number of activated processors in the complex does not change and the
operations are not performed by HP service representatives.
Both nPartitions must have iCOD software installed and configured.
