Have a customer with 4.5 DC and MP4, there are three hosts,

host = alpha
   Master/Media
   E450
   Sol 2.8
   backup net = alpha-bkup
   vm/da host

host = beta
   Media Server
    E10K
   Sol 2.6
   backup net = beta-bkup

host = gamma
   Media Server
   E10K
   Sol 2.6
   backup net = gamma-bkup

Each host has multiple net connections including a dedicated
backup communications net. In addition, SSO is in place.
In the vm.conf file I have "REQUIRED_INTERFACE = <host>-bkup"
since that is allowed in 4.5 now.  On host alpha and beta, everything
works fine and vmd communication take place over the backup net.
Now when I place the "REQUIRED_INTERFACE = gamma-bkup"
in the vm.conf, we get these problems:

-on startup, ltid kicks of vmd then it kills itself
-perform a "vmquery -h alpha-bkup -a" and vmquery dumps core
-vmd communication from alpha-bkup to gamma-bkup fails

I checked all the things I could such as /etc/hosts, /etc/nsswitch.com
/etc/system, the NetBackup install, the maintenance pack install...

When I leave the entry out of vm.conf, communications go over the
default LAN interface (which will eventually be locked down)
and everything performs fine.

Anyone see anything like this elsewhere?  


Thanks
