Solaris 10 Restore from flar image

Hi!
I want to migrate Sun Fire v240 server (sun4u) with Solaris 10 update 6 to LDOM virtual host (sun4v). I was mount NFS directory from another server in /mnt and did this steps on v240

1) I add to the /var/sadm/system/admin/.platform
PLATFORM_GROUP=sun4v

# cat /var/sadm/system/admin/.platform
#PLATFORM_GROUP=sun4u
INST_ARCH=sparc
PLATFORM_NAME=SUNW,SPARCstation-fusion
PLATFORM_ID=SUNW,SPARCstation-fusion
IN_PLATFORM_GROUP=sun4u
PLATFORM_NAME=FJSV,GP
PLATFORM_ID=FJSV,GP
IN_PLATFORM_GROUP=sun4u
PLATFORM_NAME=FJSV,GPUU
PLATFORM_ID=FJSV,GPUU
IN_PLATFORM_GROUP=sun4u
PLATFORM_NAME=SUNW,Ultra-Enterprise-10000
PLATFORM_ID=SUNW,Ultra-Enterprise-10000
IN_PLATFORM_GROUP=sun4u
PLATFORM_NAME=SUNW,Ultra-1
PLATFORM_ID=SUNW,Ultra-1
IN_PLATFORM_GROUP=sun4u
PLATFORM_GROUP=sun4v

2) flarcreate -n S10U6hybrid -U "content_architectures=sun4u,sun4v"\ -c -x /oracle /mnt/S10U5hybrid.flar

# ls -lh /mnt/S10U5hybrid.flar
-rw-r--r-- 1 nobody nobody 36G Jun 20 15:44 /mnt/S10U5hybrid.flar

# flar -i /mnt/S10U5hybrid.flar

/usr/sbin/flar[40]: print: bad option(s)

I started LDOM server from Jumpstart Solaris 10 update 7 (I also trying boot from Solaris 10u11 jumpstart with like effect)

boot net - w (or with - install option with like effect )

I chose Flash install and NFS mount option, but get ERROR: Could not find archive
I exit to shell and mount my NFS directory in local mount

I returned to Install Solaris with command

# install-solaris

and chose Local path option and /mnt/S10U5hybrid.flar path

but also get ERROR: Could not find archive

I was copy flar image to local drive on LDOM and also get ERROR: Could not find archive

Why?
Where is my error?

Having this kind of issue is not new.

You can use this:

 
 # flar split <flarfilename>
  

to split the flar file into its component parts, one of which will be a cpio archive.

Copying the flar file somewhere else and splitting it will at least enable you to check what (cpio) archive exists and that it does contain what you expected.
