GOAL:
How to know how many processors are available in AIX ?
GOAL:
How to know if Dual or Quad processors are available in AIX ?
FACT(s) (Environment):
IBM AIX
FIX:
Standard multiple processors can be counted using the UNIX instructions pmcycles -m and sar -u -P ALL 1 2.
When dealing with Dual or Quad core processors AIX should map them as multiple processors.
Example:
A Quad core processor should look like this when using pmcycles -m and sar -u -P ALL 1 2 commands:
$ pmcycles -m
CPU 0 runs at 1500 MHz
CPU 1 runs at 1500 MHz
CPU 2 runs at 1500 MHz
CPU 3 runs at 1500 MHz
$ sar -u -P ALL 1 2
