Figure 7-7 Using Partition Manager to Determine Dual-Core Processors

Determining Sibling CPUs

Once you have determined that you have a dual-core system, the siblings have adjacent hardware

paths. The first core’s path ends in an even number, and its sibling’s path ends in the following

(odd) number. For example, if the ioscan output shows:

0/10 processor Processor

0/11 processor Processor

0/12 processor Processor

0/13 processor Processor

0/14 processor Processor

0/15 processor Processor

0/16 processor Processor

0/17 processor Processor

The hardware paths for the sibling pairs are:

0/10 and 0/11

0/12 and 0/13

0/14 and 0/15

0/16 and 0/17

After vPars is installed, you can also use the vPars Monitor’s scan command to show hardware

paths.
