9.2.2 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 the nodes to start the system in single-user mode.

   [For RHEL6]

   # /sbin/shutdown now

   [For RHEL7]

   # /usr/bin/systemctl set-default rescue.target
   # /sbin/shutdown -r now

3. Mount the local file system on all the 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 the administrative LAN is shared with the public LAN, execute the following command on each node to save rcsd.cfg.

   # mv /etc/opt/SMAW/SMAWsf/rcsd.cfg /etc/opt/SMAW/SMAWsf/rcsd.cfg.work

7. If an IP address used by Web-Based Admin View also needs to be changed as the IP address of the administrative LAN is changed, change it on each node.

   See

   For details, see "7.1 Network address," "7.3 Management server," and "7.5 Multi-network between server and client by classified use" in "PRIMECLUSTER Web-Based Admin View Operation Guide."

8. Restart OS on all the nodes.

   [For RHEL6]

   # /sbin/shutdown -r now

   [For RHEL7]

   # /usr/bin/systemctl set-default multi-user.target
   # /sbin/shutdown -r now

9. If rcsd.cfg is saved in Step 6, execute the following command.

   # mv /etc/opt/SMAW/SMAWsf/rcsd.cfg.work /etc/opt/SMAW/SMAWsf/rcsd.cfg

   After that, set the shutdown facility again.
