SYMPTOMS

For example, on an IBM eServer x440 system with 16 processors, the number of processors is reported as 4 physical processors with 8 logical processors each. The correct configuration for this system is 16 physical processors with 2 logical processors each.



CAUSE
This problem may occur when you run the IBM eServer x440 system in a 16-way configuration.
