Admins,

I have fixed part of the problem and now have another question.

I fixed that by using sysman to add a static route

actually i started by issuing

route add -host backup-server hostname-back(IP address of nr1)
checked it with netstat -rn
this added a route but had the other interface nr0 listed as the interface to
use....

When I did it in sysman I chose

destination: I clicked on host and chose: backup-server
gateway: I clicked on interface and chose: nr1

this set up a route... in /etc/route
and restarted routing....

but then I had two entries for network

network/netmask (nr0 IP address)
network/netmask (nr1 IP address)

but it routes all calls to hostname-back through nr1 (good)
and all other calls (bad)

I deleted the
network/netmask (nr1 IP address)

and all is well...

Now, my ultimate goal is to get a legato save to go across the correct
interface. So I had the Legato administrator create a save group and I issued a
rsh to start the process. It works but is painfully slow. I did notice using
netstat -a that the nsrexecd process is listening on the correct port but on the
hostname nr0 interface.. all of the other connections that are established are
on the nr1 interface.... How can I start up nsrexecd to use th nr1 interface....

By the way I am running gated on a TruCluster 5.1 system (GS160). Also using
Tru64 version 5.1, patch level 3.
