8.2.2 Changing the IP address of the administrative LAN

The following describes how to change an IP address when the IP address of the administrative LAN has been changed.

Operation Procedure:

1. Execute the following command on one of the cluster nodes to stop RMS operation:

   # hvshut -a

2. Execute the following commands on all nodes to start the system in single-user mode.

   # /sbin/shutdown now

3. Mount the local file system on all nodes.

   (Example)

   /bin/mount -a -t ext3

4. Edit the "/etc/hosts" file, and change the IP address on each node.

5. Change the IP address of the administrative LAN.

   (Example)

   /usr/sbin/netconfig --ip=10.20.30.40 --netmask=255.255.255.0 -d eth0

6. If an IP address of the Shutdown Facility or the Shutdown Agent needs to be changed along with administrative LAN changes, it is necessary to change "/etc/opt/SMAW/SMAWsf/rcsd.cfg" and "/etc/opt/SMAW/SMAWsf/SA_xxx.cfg" on each node. SA_xxx.cfg indicates the configuration file for the Shutdown Agent.

   See

   For details, see "5.1.2 Setting Up the Shutdown Facility."

7. Restart the system on all nodes.

   # /sbin/shutdown -r now
