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.

NAME

       mkdevmaps - make device_maps entries

SYNOPSIS

       /usr/sbin/mkdevmaps

DESCRIPTION

       The  mkdevmaps  command  writes  to standard out a set of device_maps(4) entries describing the system's frame buffer, audio, and removable
       media devices.

       The mkdevmaps command is used by the init.d(4) scripts to create or update the /etc/security/device_maps file.

       Entries are generated based on the device special files found in /dev. For the different  categories  of  devices,  the  mkdevmaps  command
       checks for the following files under /dev:

       audio           /dev/audio, /dev/audioctl, /dev/sound/...
       tape            /dev/rst*, /dev/nrst*, /dev/rmt/...
       floppy          /dev/diskette, /dev/fd*, /dev/rdiskette, /dev/rfd*
       removable disk  /dev/dsk/c0t?d0s?, /dev/rdsk/c0t?d0s?
       frame buffer    /dev/fb
