Are you running Kerberos? If so, then you are basically out of luck
unless you really kludge up something. Both servers would need to be
in the same Kerberos realm and share a srvtab ticket. If you are not
running kerberos, then you will be ok..
Are you running Hesiod? If so, then add both servers to the
zephyr.sloc entry.
Do both clusters share the namespace? I.e., are usernames the same
across both clusters? If so, then youre in luck! If not, then
it probably wont work right.
All you need to do is set the servers to talk to each other. Each
server has a server.list file (or uses hesiod). This will get the
servers to talk to each other and exchange subscription and location
information. Then you will be able to communicate across servers.
You probably want to have all zhm processes know about both servers,
too, so if one server goes down the other server can handle the load.
Hope this helps.
