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

       dev - Device name file system

DESCRIPTION

       The  dev  filesystem  manages  the  name  spaces  of devices under the Solaris operating environment. The global zone's instance of the dev
       filesystem is mounted during boot on /dev.

       A subdirectory under /dev may have unique operational semantics. Most of the common device names under /dev are	created  automatically	by
       devfsadm(1M).   Others,	such  as  /dev/pts,  are dynamic and reflect the operational state of the system. You can manually generate device
       names for newly attached hardware by invoking devfsadm(1M) or implicitly, by indirectly causing	a  lookup  or  readdir	operation  in  the
       filesystem to occur.  For example, you can discover a disk that was attached when the system was powered down (and generate a name for that
       device) by invoking format(1M)).

FILES

       /dev    Mount point for the /dev filesystem in the global zone.

SEE ALSO

       devfsadm(1M), format(1M), devfs(7FS)

NOTES

       The global /dev instance cannot be unmounted.
