[hobbit] 2 hosts with the same name

[Kauffman, Tom]

I'm about to get into this nonsense myself. I'm running an HA
environment for two SAP systems under AIX. One of them is the SAP
Business Warehouse (now renamed to something else); on the next upgrade
the BW system will expect the hostname to match the IP address
internally at all times -- so when it moves to the fallover system, the
IP address AND hostname will need to move as well.

One of these days I'm going to flip, and implement a box with a hostname
that has no resemblance to ANY IP interface label and then try to hack
DNS to support it.

You can always get one to lie by altering runclient.sh on one of them
(alter MACHINEDOTS="`uname -n`" to something like
MACHINEDOTS="`test_uname -n`"), though I'm confused how they are running
on the network together if they have the exact same hostname...

They must have different names in the bb-hosts file, or Hobbit will not
be able to distinguish between them. So you need to make up a pseudo
hostname for at least one of them.

For the client data (assuming you have a Hobbit client on them), you can
modify the hostname it uses to report data and make sure it matches the
name you use in bb-hosts.
