Help cloning an SGI boot drive

[Mazzini Alessandro]

Hello,

I tried to clone a boot drive ( on a bigger one ), using one of the scripts on nekochan.
The disk was initialized , labelled

Then formatted by the script, and cloned. The data is present if I mount it

The issue starts when I change the id and try to boot from it... this is what I get 


esf read error, bad count
esf read error, bad count
no file system found for "unix".
unable to execute dksc(0,1,0)unix: media not loaded

autoboot failed
dksc(0,1,0)unix: media not loaded


>From Prom, ls gives :

dksc(0,1,8)/:
sgilabel sash symmon
esf read error, bad count
no file system found for "/".


Any suggestion is accepted.
