web flash archive installation

I am trying to install Solaris 9 on our sun fire 280R using web start flash archive.
The master system is a Sun fire v480 and has it root file system mirrored using Sun's disk suite. Both �Machine A� and �Machine B� have the same number of disks and of the same size

The flash archive was created from master system (machine A) using flarcreate like

Flarcreate -n puffin-20070629 -x /proc -x /var/run -x /home -x /clone -R / -S -c /clone/puffin-20070629.flar

I then NFS export to image to the clone machine (machine B)

On �machine B� from the OK prompt, I boot from cdrom like

Ok boot cdrom - w

When prompt for a media type I entered �Network file System�

Unfortunately when �Machine B� finishes extracting the archive it panics.
�Machine B� was running fine before trying to �Web flash installation�
Can you help please?

Here is the error message
NFS moon:/free/puffin/puffin-20070704.flar

Can you help? please

Thanks

Hi hassan,
at the beginning of your post you tell us that the system you create the flash is a system with root mirroring.
This should be the problem, because so far I no the md (metadb -a)description is on additional slices.
But this slice is not inside the flash archive.
Due too this fact you are not able to find the root partition on your client system and the result is a system panic.

Best regards
joerg
