Hi,

Testing on an AIX 7.3 system with 1 processor (SMT-8 / 8 hw-threads =~ 8 logical/virtual cores/cpus). The OS runs virtualized on PowerVM, as almost everything on Power does.

OSHI reports the following: lcpus=5, procs=5, sockets=1

• sockets = systemInfo.getHardware().getProcessor().getPhysicalPackageCount();
• procs = systemInfo.getHardware().getProcessor().getPhysicalProcessorCount();
• lcpus = systemInfo.getHardware().getProcessor().getLogicalProcessorCount();

I would expect 1 socket, 1 processor and 8 logical processors.

From the OS i can see:

# lparstat

System configuration: type=Shared mode=Uncapped smt=8 lcpu=8 mem=4096MB psize=28 ent=0.25

%user  %sys  %wait  %idle physc %entc  lbusy  vcsw phint  %nsp  %utcyc
----- ----- ------ ------ ----- ----- ------ ----- ----- -----  ------

# vmstat

System configuration: lcpu=8 mem=4096MB ent=0.25

To me it seems like an error, but I have only tested on 1 system.

Would like to hear your comments.
