Select the second network interface you want to change, for instance en3, until it is highlighted.
Press
Enter
to change. In the
INTERNET ADDRESS (dotted decimal)
field, type the new IP
address 100.100.51.123. In the
Network MASK (hexadecimal or dotted decimal)
field, type the
network mask 255.255.255.0 of the new network. Press
Enter
.
Check the result of the command at the
COMMAND STATUS
window of SMIT. The
Command
field shows OK while the text below says en3 changed. Escape SMIT by pressing
F10
.
Step 9 - Verify the new addresses are working
1.
From the AIX command line use the command
ping
for all the addresses (except the cluster
service address) to verify they are working correctly. Because you are logged in to drs_engine2,
start to
ping
on drs_engine2. See Ping
command to verify IP addresses are working
for the
ping
command and its results. Stop the
ping
command each time a result is displayed with the
Ctrl+C
key combination.
Ping command to verify IP addresses are working
# ping 100.100.51.123
PING 100.100.51.123: (100.100.51.123): 89.6 data bytes
64 bytes from 100.100.51.123: icmp_seq=0 ttl=255 time=0 ms
64 bytes from 100.100.51.123: icmp_seq=1 ttl=255 time=0 ms
64 bytes from 100.100.51.123: icmp_seq=2 ttl=255 time=0 ms

----100.100.51.123 PING Statistics----
3 packets transmitted, 3 packets received, 0% packet loss
Round-trip min/avg/max = 0/0/0 ms
You should check all 4 addresses with the ping command.
1.
Use the Keyboard Video Mouse (KVM) switch to go back to drs_engine1, that is, use the
PrtSc
key and select drs_engine1 (or whatever name you are using). Since you never logged off from
that engine, you do not need to identify yourself again. Use the
ping
command again to verify all
addresses (except the cluster service address) are working correctly. Stop the
ping
command
each time a result is displayed with the
Ctrl+C
key combination.
Important:
Network connectivity is important for HACMP functionality. Verify network
connectivity any time you make changes to the network interfaces or network
environment.
Step 10 - Remove network from the HACMP cluster
Regardless on what engine you are, start the SMIT HACMP menus by typing
smitty hacmp
on an
AIX command line.
1.
Go to
Extended Configuration -> Extended Topology Configuration -> Configure HACMP
Networks -> Remove a Network from the HACMP Cluster
. In the
Select a Network to
Remove
window, select net_ether_01 (make sure not to select net_ether_02, because this is the
HACMP heartbeat network) and press
Enter
.
2.
In the
ARE YOU SURE?
window, press
Enter
to proceed. Check that the result is OK, press
F3
twice.
