It's trying to discover the IP address that the rest of the world would
use to contact this machine. (In the general case this is much harder
than it sounds; it can be impossible. 'getent hosts `hostname`' is a
pragmatic approach that usually works but it's not bulletproof. 'utadm'
will error out if 'getent' fails or produces an obviously incorrect address.
If 'getent' just hangs then you'll get the behaviour you're seeing.)

Right. 'utadm' knows that 127.0.0.1 is the internal loopback address,
and that can not possibly be an address that the rest of the world
can use to contact this machine.

That's because 'utadm' knows (from the "# SUNRAY-ADD..." comment)
that this line identifies the IP address of the private Sun Ray interconnect
you configured on the nge0 interface. 'utadm' therefore feels free to
delete this line when you tell it to unconfigure the nge0 interconnect.

You need to associate the "odin" hostname with an IP address that
the rest of the world can see. Not with the loopback IP address, and
not with the IP address of a Sun Ray interconnect. Pick one of the
addresses that the machine has *before* you configure teh nge0
interconnect.
If nge0 is the machine's connection to the rest of the world then it
isn't a candidate for being a dedicated private Sun Ray interconnect
and you shouldn't use 'utadm -a' to set up Sun Ray service. You
should use 'utadm -A' instead to set up Sun Ray service on what is
really a general-use subnet.
