I think someone is misunderstanding some industry buzz words here ...
NAS refers to Network Attached Storage, as in via NFS, AFS, et al.
What your showing in the output of the Solaris format command are
raw SCSI LUNS attached via fibre channel (fabric or loop) or native scsi.

How is it attached? Using FACL or ISCSI?
In any case, it seems to be a natural solution to do it this way.
In order to access a network disk, you need to obtain the right to
do so first. Once this has been done, the netork subsystem just looks
like a new SCSI bus.
