All
I have the problem and wondered if anyone else has run into this
Its a proof of concept design we are attempting to use in our organisation,
clients are UAT boxes and in the event of problems with a live box the UAT
box needs to be configured as a live prod host, rather than fiddling with
dual boots and worrying about keeping them in sync, its been decided that
we will treat Fujitsu PP850's like a linux blade and any problems we have
we just re-build it as a new host or as itself if it develops a problem.
jump server is PP850 with two quad cards, it has one connection to public
network, in port 3 of one the quad cards is a cross over cable which i will
call uat, in port 4 is another cross over cable which i will call prod.
the two cross over cables are connected to another PP850 (same spec as jump
server) and is connected into same ports as the jump server
on the client devalias has been set up as shown (in bold)

the scenario is that the client needs to configured from a uat box to a
prod box, this is done by re-jumping the client as a prod box via the prod
network interface
{c} ok boot prod - install (to re-jump it as a uat box use
boot uat - install)
doing a snoop on both interfaces on the jumpstart server reveals primarily
that all traffic was on the prod network but eventually the client and jump
server do talk on the uat network and that thsi causes confusion and the
client is always built as a uat box - not sure if this is because it sees
it first on the card ie mac address ie last figure is a compare to b
if i comment out the uat entry in /etc/ethers, prod box builds fine
will summarise
thanks
