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.

   For details on how to change the IP address, see the Linux documentation.

6. If an IP address of the Shutdown Facility or the Shutdown Agent needs to be changed along with the IP address of the 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.
