Thanks so much for the information.
ok, seems this is the only supported options when mounting a nfs in Solaris...
read/write/setuid/devices/nohidden/nofoldcase/dev=19a3010

Also in the manual I cannot find how to mount it using tcp or udp, hard or soft. Anyone knows what are the default for the ff:
tcp or udp?
hard or soft?
rsize/wsize size?
nfs version?
intr or nointr?
timeo=?
etc....

Some of these options will definitely depends on the client.

thanks,
warren
