HP Superdome 2 Partitioning Administrator Guide (5900-2540, December 2012)

Example
• To add the CPU at 1/1/0/0 (enclosure 1, blade1, socket 0, core 0) and 1/1/0/1 to
vPar0001:
vparmodify -N <nPar name> -p <vPar name> -a cpu:1/1/0/0 -a
cpu:1/1/0/1
CPU: Summary Information
Impact on vPars Commands: Specifying CPU
Table 7 (page 85) lists the CPU resource paths in the following four ways:

Deleting CPU-cores Summary
• If the vPar is up or down, you can delete only a specific CPU by using a by-path deletion.
If the vPar is down, you can delete only by-path CPUs that were assigned by path, because
at that point, the by-count and by-socket assignments will be just counts, and not specific CPUs.
CPU Allocation
On HP Integrity Superdome 2, the parstatus command provides all the required CPU information
from the OA without installing or booting to the nPar mode.
To map the HP-UX hardware paths in the newly created vPar to the resource paths used to create
it, call ioscan using the option -m resourcepath that maps HP-UX hardware paths to resource
paths.
The first vPartition is configured with the AD221 Ethernet / Fibre channel combination card at
hardware address 48/0/0/2/0/0/2/0. Run the following command to view the configuration:
# ioscan –m resourcepath | grep cpucore
