Hello,
I would like to check how many SAS disks and its size per disk for the whole power system. As per my understanding, if we assign the SAS controller to LPAR, then we can see the disk in lpar smitty command.
How can we check from the Power machine(physical ones) as well? I think the power system should know how many disks it has and its size.
I have check in ASMI page, and in the console SMS, I can see some disks, but not see the size (screenshot attached).
It depends quite what you are looking for. Do any of these help (sorry but I no longer have access to AIX so I'm a bit rusty!)
lspv
lspv -v
lspv -l
lsvpcfg # (possibly with a -l flag?)
lsdev -Cc disk # Bit of a long shot perhaps
lscfg -v|grep -i disk # Again, a bit of a guess
What are the metrics you are looking for? Is it the LPAR view of the assigned disk to the size of the disk that is owned by the hardware as a whole? The LPAR will not see that.
I hope that these suggestions give you something.
Robin
from the hardware itself, you cannot see the disks - you can only see the controllers, not what is attached to them.
As part of the SMS menu you can see the disks and sizes if you query the controllers - or when you install AIX as you have to select a suitable disks for the installation - with location code.
If you have AIX already installed, run these commands.
to find your SAS disks, run
lsdev -Cc disk | grep -i sas
to figure out the disk size of said disks use
getconf DISK_SIZE /dev/<hdisk>
Thank Robin, I would like to check at the physical hardware console, not from LPAR, have not LPAR right now.

Hi Zxmaus,
I understand now that from physical hardware Power Machine we cannot check the disk and size.
Still have 1 thing to ask, for SAS disk, I see it is part of raid controller. The disk is called pdisk. After configuring raid, it becomes hdisk which AIX can see. The question is, if in the first time, we assign the controller and its disks to LPAR to install AIX. How can we configure the raid before AIX OS can see these disks?
Hi,
please check out this link and see if that works - our boxes come always preconfigured, so I cannot guarantee for it 
Hi Zmaus,
The link is very useful :)
