activated processors in the nPar (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 nPars in the same server complex: deactivate
processors in one nPar and activate the same number of processors in
another nPar.
NOTE After “load balancing” processors across nPartitions, each nPar still has
the same cells and processors assigned to it.
However, this procedure reduces the number of activated processors in
the first nPar 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.
Also, both nPartitions must have enough activated or deactivated
processors to accommodate the reduction or increase in processors.
Step 1. Login to the first nPartition and deactivate the number of processors you
plan to activate in the second nPar.
Refer to the procedure Activating and Deactivating Processors with iCOD
on page 320, and use the icod_modify -d... command to deactivate
the processors.
