Problem(Abstract)
The NUMCPUVP onconfig parameter should be set to one less than the actual number of physical CPUs present in the server. This document provides the commands to determine the number of CPUs on AIX machines before setting the parameter.
Resolving the problem
On AIX you use the command lsdev to determine how many CPUs your system has. The command lsdev (located in /usr/sbin) is used to list the system devices. Use it with the following options to list all processors one per line:
- /usr/sbin/lsdev -C -c processor
- Example:
This example is from a single processor system.
- $ lsdev -C -c processor
proc0 Available 00-00 Processor
