HP-UX: LVM migration from legacy to agile addressing onto a failover server

Hi there!

I'm having problems migrating and vgimport onto a different server. Original server uses the legacy DSF naming (ctd naming like /dev/dsk/c0t1d0) and the new server where i'm migrating those luns to is using the Agile addressing (i.e persistent DSF i.e. /dev/disk/diskxxx)
Importing a VG with 11 disks. Actually some of the disks with names /dev/disk/diskxxx doesn't map to legacy DSFs due to 8 lun limit per target on HP-UX initiators.
So, only /dev/dsk/c0t1d0 , /dev/dsk/c0t1d1 , ...., /dev/dsk/c0t1d7 are available and rest of the three devices in 11 luns are missing (is there a way to create?) where i have Agile devices like /dev/disk/disk401,/dev/disk/disk402,...,/dev/disk/disk411 are available.

when i use vgimport -v vgdata01 /dev/disk/disk401 /dev/disk/disk402 /dev/disk/disk403 /dev/disk/disk404 /dev/disk/disk405 /dev/disk/disk406 /dev/disk/disk407 /dev/disk/disk408 /dev/disk/disk409 /dev/disk/disk410 /dev/disk/disk411
it won't succeed.
OS version: 11.31
Appreciate your help. Thanks.

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

NAME
dtc_kill_vps_disk - destroy LVM disks for freeing space SYNOPSIS
dtc_kill_vps_disk VPS_NUMBER [ lvm|loopback ] DESCRIPTION
dtc_kill_vps_disk 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 delete a partitions that was used by a VPS. It will delete the normal partition that was used as a root disk, and the swap partition. dtc_kill_vps_disk is to be used by the dtc-xen SOAP server, but can also be used as a standalone userland tool. 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. 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 lvm This will delete the 2 LVM partitions that were used by the VPS named xen04, the first one being the root partition, and the second one being the swap partition. VERSION
This documentation describes dtc_kill_vps_disk See http://www.gplhost.com/software-dtc-xen.html for updates. SEE ALSO
