How to find exact number of Physical & Logical Processors in this Blade BL870c i4 system??

Hello Experts,
I am trying to understand this Blade system - no. of CPUs.

The Quick specs sheet shows me the that:
"Intel(R) Itanium(R) Processor 9560 (2.53 GHz, 32 MB)" is 8 cores processor.
------------------------------
root@vParHost / #model
ia64 hp Integrity BL870c i4
----------------------------------
root@vParHost / # uname -a
HP-UX vParHost B.11.31 U ia64 1690622199 unlimited-user license
------------------------------------------------------------------------------------
root@vParHost / # setboot
....
Hyperthreading : ON
--------------------------------------------------------------
Following shows me
root@vParHost / # ioscan -fnC processor | more

processor 0 0/120 processor CLAIMED PROCESSOR Processor
processor 1 0/122 processor CLAIMED PROCESSOR Processor
processor 2 0/124 processor CLAIMED PROCESSOR Processor
processor 3 0/126 processor CLAIMED PROCESSOR Processor
processor 8 1/120 processor CLAIMED PROCESSOR Processor
processor 9 1/122 processor CLAIMED PROCESSOR Processor
processor 10 1/124 processor CLAIMED PROCESSOR Processor
processor 11 1/126 processor CLAIMED PROCESSOR Processor
processor 12 1/128 processor CLAIMED PROCESSOR Processor
processor 13 1/130 processor CLAIMED PROCESSOR Processor

2 Enq2_vpar 1/512 2 8 24576 0
----------------------------------------------------
root@vParHost / # vparstatus -A
[Available CPUs]: 9

>> So, Above 4 + 2 = 6 no.s of CPU allocated to vPars + 9 CPUs = 15 CPUs
-------------------------
But the machinfo
root@vParHost / # machinfo | more
CPU info:

Intel(R) Itanium(R) Processor 9560 (2.53 GHz, 32 MB)
8 cores, 16 logical processors per socket
6.38 GT/s QPI, CPU version D0
Active processor count:
2 sockets
10 cores (4 to 6 per socket)
10 logical processors
LCPU attribute is disabled --> my understanding --> This shows whether HyperThreading is disabled

So I think its >> 10 Logical processors
