Deleting CPU-cores Summary

If you want to control which CPU-core is deleted, use the same method—by SLP, by resource
path, or by count-on your deletion command line that you used on your addition command
line.

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
1/120
1/122
1/124
1/126
1/128
1/130
1/132
1/134
or, for this example, run the following command.
# # ioscan -m resourcepath | grep 48/0/0/2/0
48/0/0/2/0
48/0/0/2/0/0

Memory

There are two major types of memory addressing, Socket Local Memory (SLM), and InterLeaved
Memory (ILM). With SLM, entire memory address ranges are from a single socket. For best
performance, memory and CPU-cores from the same sockets must be assigned to a vPar. ILM is
an address range of memory whose adjacent addresses reside on one or more sockets in the
underlying nPartition.
Memory Granularity
The nPartition memory is divided into multiple memory granules by firmware to assign memory
easily to vPars. The size of these memory granules can be optionally specified by the user. Memory
granularity refers to the size of these memory granules.
