What is a command to check number of CPU/Cores AIX 6.1 OS running on. AIX is on PowerVM LPAR.

Question : What is a command to check number of CPU/Cores AIX 6.1 OS running on. AIX is on PowerVM LPAR.

I need a command to check the number of CPU/cores AIX 6.1 running on.
AIX running in virtual environment – PowerVM LPAR.


Solution: What is a command to check number of CPU/Cores AIX 6.1 OS running on. AIX is on PowerVM LPAR.

lsdev -Cc processor will show the number of physical processors (or virtual processors in a shared processor LPAR.

1. lsdev -Cc processor

proc0 Available 00-00 Processor
proc2 Available 00-02 Processor
SMT thread processors are seen with bindprocessor

1. bindprocessor -q

The available processors are: 0 1 2 3

lparstat -i will show the virtual and logical processors.

1. lparstat -i | grep CPU

Online Virtual CPUs : 2
Maximum Virtual CPUs : 15
Minimum Virtual CPUs : 1
Maximum Physical CPUs in system : 2
Active Physical CPUs in system : 2
Active CPUs in Pool : 2
Physical CPU Percentage : 25.00%

topas -L shows logical processors,
mpstat shows virtual

1. lsattr -El proc0

frequency 1498500000 Processor Speed False
smt_enabled true Processor SMT enabled False
smt_threads 2 Processor SMT threads False
state enable Processor state False
type PowerPC_POWER5 Processor type False

1. lscfg -v | grep -i proc

Model Implementation: Multiple Processor, PCI bus
proc0 Processor
proc2 Processor
