EPC Connecting Guide
In order to configure the other adapters on a node, please use the SMIT Further
Configuration menus. Otherwise the HOSTNAME would be changed.
For that type #smit tcpip
Then through the sequence of displayed menus
select

Broadcast Address
Note: The interconnects of an Escala Powercluster define separate IP networks. The IP
addresses used on two interconnects pertain to two different networks.
Updating the Name Directories
The following applies to an interconnect. Do it as many times as there are interconnects.
On node #1 append the node name and IP address to the /etc/hosts file
100.100.100.1 node1_X
create /.rhosts file with node #1, node #2 and other nodes, if any
# vi/.rhosts
insert
node1_X
node2_X
...
On node #2 append the node name and IP address to the /etc/hosts file
100.100.100.2 node2_X
create /.rhosts file with node #1, node #2 and other nodes
# vi/.rhosts
insert
node1_X
node2_X
...
And so on for the other nodes.
Checking the Interconnection of the Nodes
On node #1 ping every node and check reachability with every node
# ping node2_X
# rsh node2_X uname –a
which returns AIX node2_X
# ping node3_X
# rsh node3_X uname –a
which returns AIX node3_X
and so on.
