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!)
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.

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
to figure out the disk size of said disks use

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!
I replaced a failed pdisk in the raid enclosure as follows,
- rmdev -l 'pdisk18' '-d'
- Replaced it.
- cfgmgr (detected)
- I can see the new drive, with the correct serial #
lscfg -v -l pdisk18

Hi,
I have installed the HMC on the VMWare VM. I try to add the power machine (managed system) and asking for a password? So this is the IBM predefined password of Power Machine?
In the VMWare perspective, we can login to ESX host to do some management tasks. But how about the Power machine?... (6 Replies)

I don't like the new concept of the power ha 7 cluster with the repository disk and the internal solidb, I really would like to mirror this disk, but the "IBM PowerHA SystemMirror 7.1 for AIX" redbook says, normal lvm operations should not be performed on this disk.

Hi!!
I am these days working on a project, where I need to know about the disk controllers available in a machine (e.g., 3ware,IBM,etc).
