It doesn't work.
actually the disk doesn't exist, but some how it is showing up in the LPAR

Code:
root@clodb:/>chdev -l hdisk2 -a pv=clear
Method error (/etc/methods/chgdisk):
        0514-047 Cannot access a device.
     pv

root@clodb:/>chdev -l hdisk2 -a pv=yes
Method error (/etc/methods/chgdisk):
        0514-047 Cannot access a device.
     pv

root@clodb:/>lspv
hdisk9          00c7780e5a93d490                    rootvg          active
hdisk10         00c7780e9a335af3                    backupvg        active
hdisk13         00c7780eb79e72f6                    oradbvg         active
hdisk11         00c7780e723bb1e0                    bkclodbvg       active
hdisk2          none                                None
root@clodb:/>

I did ODM delete also, restarted the machines then the hdisk appeared as hdisk0

but it is not going.

NAME
partx - telling the kernel about presence and numbering of on-disk partitions. SYNOPSIS
partx [-a|-d|-l] [--type TYPE] [--nr M-N] [partition] disk DESCRIPTION
Given a block device ( disk ) and a partition table type , try to parse the partition table, and list the contents. Optionally add or remove partitions. This is not an fdisk - adding and removing partitions is not a change of the disk, but just telling the kernel about presence and numbering of on-disk partitions. OPTIONS
-a add specified partitions or read disk and add all partitions -d delete specified or all partitions -l list partitions. Note that the all numbers are in 512-byte sectors. --type TYPE Specify the partition type -- dos, bsd, solaris, unixware or gpt. --nr M-N Specify the range of partitions (e.g --nr 2-4). SEE ALSO
addpart(8), delpart(8), fdisk(8), parted(8), partprobe(8) AVAILABILITY
The partx command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/. 11 Jan 2007 PARTX(8)
