CPU Allocation On HP Integrity Superdome 2, parstatus command provides all the required CPU information from the OA without installing or booting to nPar mode. From HP-UX, ioscan is used to retrieve CPU information. However ensure that CPU resource paths are determined using the option -m 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 1/120 1/122 1/124 1/126 1/128 1/130 1/132 1/134 0x100ff02ff000017 0x100ff02ff000117 0x100ff02ff000217 0x100ff02ff000317 0x100ff02ff010017 0x100ff02ff010117 0x100ff02ff010217 0x100ff02ff010317 or, for this example, run the following command. # # ioscan -m resourcepath | grep 48/0/0/2/0 cpucore-1/2/0/0 cpucore-1/2/0/1 cpucore-1/2/0/2 cpucore-1/2/0/3 cpucore-1/2/1/0 cpucore-1/2/1/1 cpucore-1/2/1/2 cpucore-1/2/1/3 48/0/0/2/0 48/0/0/2/0/0 0x900010002ffff8e 0x90001000203ff85 iorp-9/1/0/0/2 ioslot-9/1/3 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 socket(s) should 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. Planning Your Virtual Partitions 77
