trucluster and multihoming

[No Body]

have a trucluster system providing access to a database. the cluster is
a failover cluster. the location of the system is going through a move
along with a addressing/subnet change. i've been asked to set up a
second ip address on the cluster/shared 'interface' of the nodes
facilitating migration of other systems to the new subnet (along with
eliminating tons of hardcoded addressing to this box). is this possible?
i've tried digging through the docs and can't find a reference to such a
thing. i've experience with tru64 itself and feel pretty comfy with it
but trucluster came into our lives via a acquisition and i'm admittedly
quite green (plus, of course, only one cluster.. no dev cluster to test
with).

if anyone has any input or pointers to the right spot in the docs i'd
appreciate it. thanks.

Hi r,

Yes you can. You can add extra entries to rc.config for every extra
IP-Address you want to add.

NETDEV_0="tu0"
export NETDEV_0
NETDEV_1="tu0"
export NETDEV_1
IFCONFIG_0="10.31.110.20 netmask 255.255.255.0"
export IFCONFIG_0
IFCONFIG_1="10.31.120.20 netmask 255.255.255.0"
export IFCONFIG_1
NUM_NETCONFIG="2"
export NUM_NETCONFIG

Now you have two IP-Addresses on interface tu0. In my experience you have to
reboot for it to work correctly. Restarting /sbin/init.d/inet does not help.

That should be all
