1st you need to make sure that "siebelvg" is going to be shared between nodes? if its not then you don't need to enable enhance concurrent on that, and if you are sharing the VG then
Change the VG to Big VG
run
Code:
lsvg siebelvg | egrep "MAX PVs:"   --> look for PV, for normal VG it will be 32

chvg -B siebelvg     --> This will change the VG to Big VG and this is dynamic, no need to varyoff vg.

lsvg siebelvg | egrep "MAX PVs:"   --> The PV no increases to 128

Now run 
lsattr -El siebelvg  --> ( and look for below)
auto_on       y 
....
conc_capable  n
....
Run

chvg -C siebelvg   --> This command will change the VG to enhance concurrent capable, and this is dynamic, no need to varyoff vg.

lsattr -El siebelvg  --> ( and look for below)
auto_on       n     --> Auto varyon will change to no
....
conc_capable  y   --> Enhance concurrent capable is changed to yes.
....

dtc_setup_vps_disk

dtc_setup_vps_disks(8)					      System Manager's Manual					    dtc_setup_vps_disks(8)

NAME

       dtc_setup_disk - setup LVM disks for using it as a VM

SYNOPSIS

       dtc_setup_vps_disk.sh VPS_NUMBER HDD_SIZE SWAP_SIZE [ lvm|loopback ]

DESCRIPTION

       dtc_setup_vps_disk.sh This shell script is a part of the dtc-xen package that is to be used by the dtc panel to manage a Xen VPS server.

       This script is used to create partitions to be used by a VPS later on.  It will create a normal partition that will be used as a root disk,
       and a swap partition.

       dtc_setup_disk is to be used by the dtc-xen SOAP server, but can also be used as a standalone userland tool.

       If the partition(s) exists, then this script will delete it/them first.

OPTIONS

       VPS_NUMBER has to be a number between 01 and 19. Let's say the number is 16, and that dtc-xen is configured to use the volume group  called
       lvm1, then this script will create /dev/lvm1/xen16 and /dev/lvm1/xen16swap.

       HDD_SIZE Size in MB of the VPS partition to create.

       SWAP_SIZE  Size in MB of the VPS swap partition to create. If the dtc-xen SOAP server is used to create the VPS, then it will create a swap
       partition of the exact same size as the memory.

       IMAGE_TYPE This parameter can have 2 values: either lvm or loopback. If ommited, then lvm is used. If lvm is used, then	this  script  will
       create a partition using lvmcreate, otherwise it will create an image file. Both will later be used for the VPS.

EXAMPLE

       dtc_setup_vps_disk 04 15360 256 lvm

       This will create 2 LVM partition to be used by the VPS named xen04, the first one being a root partition of 15 GB, and the second one being
       a swap partition of 256 MB.

VERSION

       This documentation describes dtc_setup_vps_disk version 0.3.15.	See http://www.gplhost.com/software-dtc-xen.html for updates.
