Hello ALl;
Thanks for those replying!
Darren Dunham is entirely correct.
Firstly, with regards to the type at newfs (it was indeed newfs
/dev/rdsk/c1t1d0s0 and not newfs /dev/rdsk/c1t1d0s2).
Secondly also on my entirely incorrect interpretation of the message.
Thanks once again. A mistake on my part.
This is a wonderful list.
Warmest Regards
Steven Sim
