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.

Thank Robin, I would like to check at the physical hardware console, not from LPAR, have not LPAR right now.

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
Code:
lsdev -Cc disk | grep -i sas

to figure out the disk size of said disks use
Code:
getconf DISK_SIZE /dev/<hdisk>

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?

vxbootsetup

vxbootsetup(1M) 														   vxbootsetup(1M)

NAME

       vxbootsetup - set up system boot information on a Veritas Volume Manager disk

SYNOPSIS

       /etc/vx/bin/vxbootsetup [-g diskgroup] [medianame ... ]

DESCRIPTION

       The  vxbootsetup utility configures physical disks so that they can be used to boot the system. Before vxbootsetup is called to configure a
       disk, the required volumes, standvol, rootvol and swapvol (and optionally, dumpvol) must be created on the disk.  All of these volumes must
       be contiguous with only one subdisk.

       The -g option may be used to specify the boot disk group.

       If  no  medianame arguments are specified, all disks that contain usable mirrors of the root, swap, /usr and /var volumes are configured to
       be bootable.

       If medianame arguments are given, only the disks that are associated with the specified disk names are configured to be bootable.

       vxbootsetup requires that:

       o    The root volume must be named rootvol and must have a usage type of root.

       o    The swap volume must be named swapvol and must have a usage type of swap.

       o    The volumes containing /usr and /var (if any) must be named usr and var, respectively.

       See the chapter "Recovery from Boot Disk Failure" in the Veritas Volume Manager Troubleshooting Guide for detailed information on  how  the
       system boots and how VxVM impacts the system boot process.  The vxmirror, vxrootmir, and vxresize utilities call vxbootsetup automatically.
       If you use vxassist, or vxmake and vxplex to create mirrors of the root volume on a disk, you must run vxbootsetup explicitly to  make  the
       disk bootable.

ARGUMENTS

       medianame
	    Specifies the disk name (disk media name) of a VM disk that is to be configured as bootable.
