How do I know my global zone nodename from a non-global zone ?

That's what I found on the Web.

For Solaris Zones, the method I use is the one devised by Menno Lageman (http://blogs.sun.com/menno). Mount the global zone's /etc/nodename using a read-only LOFS mount on /etc/chassis in the non-global zone. It automatically changes whenever the nodename of the global zone changes, whether it is because the name of the global zone is modified or because the zone is moved to another physical host using zoneadm detach/attach. Just do this:


# zonecfg -z zone

zonecfg:zone> add fs

zonecfg:zone:fs> set dir=/etc/chassis

zonecfg:zone:fs> set special=/etc/nodename

zonecfg:zone:fs> set type=lofs

zonecfg:zone:fs> add options ro

zonecfg:zone:fs> end

I did not try this yet, I have no appropriate Solaris box by hand. But that could be useful.
