Great response, many thanks to all who replied. Many suggested editing
/etc/inet.local, but I stayed with rc.config.
I adopted Michael Bradford's suggestion;
You need to alter the lines in rc.config to:
NETDEV_0="nr0"
IFCONFIG_0="174.28.48.99 netmask 255.255.0.0"
NETDEV_1="nr0"
IFCONFIG_1="alias 6.5.4.202/16"
Also needed to increase (suggested by Roger!);
NUM_NETCONFIG="2"
Original question and all responses follow...

15/01/2003 09:59
Hi all,
Version Compaq Tru64 UNIX V5.1 (Rev. 732), non-cluster, using NETRain.
How can I setup more than one IP address for a single virtual "netrain"
adapter which will survive a reboot?
We have tried the following in rc.config (where 174.. is normal address,
and 6.. is second address) ;
NETDEV_0="nr0"
IFCONFIG_0="174.28.48.99 netmask 255.255.0.0"
NETDEV_1="nr0"
IFCONFIG_1="6.5.4.202 netmask 255.255.0.0"
but after a reboot it only has the first IP address. MAX_NETDEVS="8"
TIA

Is NUM_NETCONFIG = 2 ?
== Phil Baldwin
Don't think you can do it in rc.config (couldn't see anyway)
but what you could do is add the necessary line to the /etc/inet.local
file.
This should run at system startup and add the required alias see man
inet.local
== Dennis Voetelink
As far as I know, the only possibility is to use
# ifconfig nr0 alias 6.5.4.202 netmask 255.255.0.0
to add the second IP address.
Use -alias to remove it.
I'm afraid you'll need to write your own startup script for this and place
that in /sbin/init.d with a symlink to it in /sbin/rc3.d

I think you have to call this an "interface alias". We set this (for a
single interface) with a line in /etc/inet.local:
ifconfig ee3 alias <your.ip.alias.address> netmask <your.valid.subnet.mask>
This should also work for you if the NetRain interface is
already configured an up.
== Christian Wessely
I have had the same object:
assign a second IP to a network adapter that serves as a virtual
Webserver (with apache).
Solution for me was a little shellscript and the alias option of ifconfig:
/sbin/init.d/alias contains
---------------------------------
#!/bin/sh
# This file should have uid root, gid sys and chmod 744
#
case "$1" in
'start')
#
# Edit these lines to suit your installation (paths, workgroup, host)
#
/sbin/ifconfig tu0 alias X.Y.105.21
/sbin/ifconfig tu0 alias X.Y.105.25
;;
'stop')
/sbin/ifconfig tu0 -alias X.Y.105.21
/sbin/ifconfig tu0 -alias X.Y.105.25
;;
*)
echo "Usage: `basename $0` { start | stop }"
;;
esac
---------------------------------
In my case, this script is called by the awemanager when the cluster
starts; for a single machine i would just recommend to cd /sbin/rc3.d ;
ln -s yourscript to Sxxalias so that it is integrated in the normal
start procedure.
Perhaps you can use the alias option directly in the rc.config, but I
have not dealt with that.

Add a line in /etc/inet.local reading:
/sbin/ifconfig nr0 alias 6.5.4.202 netmask 255.255.0.0
Remove the entry in rc.config
