• By individual core hardware path: In this method you can explicitly specify each individual
core. The format for this method is —a cpu:{enclosure}/{blade}/{socket}/{core}. For more
information on hardware paths, see vparresources and vparmodify help pages on the OA
and manpages on HP-UX.
Systems with iCAP have the following differences:
1. You must have both physically available cores and available Right to Use (RTU) licenses (or
a positive Temporary Instant Capacity balance and authorization to use it).
2. The iCAP subsystem provides you an additional method for making online modifications
(beyond vparmodify). You can also use the icapmodify to add, remove, or set the total
number of cores, but it can done only by count method. This command can be run from either
the OA or the partition that is being modified. The format for this is:
MyComplex> icapmodify —p {npar_id:vpar_id} —[as] {count}
or, as issued from the OS command line in the affected partition:
# icapmodify —[as] {count}
The system selects the best available cores when it uses the icapmodify command on a LORA
enabled system.
Deleting cores from a running nPartition
Cores can be deleted online in the same way that it is added. The vparmodify command is used
to delete the cores. For complexes with iCAP components both vparmodify and icapmodify
commands are used. Similar to core addition, the cores can be deleted by specifying:
• count of cores to be removed
• a count of cores from a specific socket to be removed
• individual cores specified by hardware path
NOTE: The boot processor cannot be removed from a running vPar, so online operations must
keep at least one core in the vPar.
