hostids on F15K

Hi,

Got one here for the experts on the big toys.

We have an app running of an F15K domain. The app is licensed against
hostname and
hostid. These values are obtained via "hostid" and "uname -n". Easy enough
so far.

The problem is that we've just built a new domain and the licenses provided
(we had
several attempts) never work. The difference between the new domain and the
old
working instance is that the new one does all it's networking via a couple
of Cassini
cards (ce gigabits) whereas the old one had these plus a QFE card.

I can't recall exactly how a 15K domain picks up it's hostid value.

I'm also wondering if the app licensing software is picking up the eri card
used for
backplane comms.

I've tried to truss the licensing steps and it looks like the software
calls sysinfo and gets
SI_HW_SERIAL. The number is comes back with doesn't look anything like the
hostid so
I'd like to know where this value comes from.

If anyone can tell me how these components may interact I'd appreciate it.

TIA

Joe
