PRIMECLUSTER Installation and Administration Guide4.5

9.2.2 Changing a CIP Address

This section describes how to change the IP address after the PRIMECLUSTER system is installed.

Operation Procedure:

1. Start all the nodes that constitute the cluster system.

2. Stop CF on all nodes that constitute the cluster system.

   For information on how to stop CF, see "4.7 Starting and stopping CF" in "PRIMECLUSTER Cluster Foundation (CF) Configuration and Administration Guide."

3. While referring to the cip.cf file, confirm the CIP name to change the IP address.

   For details on the cip.cf file, see "1.2 CIP configuration file" in "PRIMECLUSTER Cluster Foundation (CF) Configuration and Administration Guide" and the manual page describing cip.cf.

4. For the IPv6 address, edit the cip.cf file and change the IP address corresponding to the CIP name.

   When the original address and the modified address are both IPv4, you do not need to change it.

   Perform this procedure on all the nodes constituting the cluster system.

5. Change the IP address of the CIP name that is defined in the hosts(4) file.

   Perform this procedure on all the nodes constituting the cluster system.

6. Start CF on all the nodes constituting the cluster system.

   For instructions on how to start CF, see "4.7 Starting and stopping CF" in "PRIMECLUSTER Cluster Foundation (CF) Configuration and Administration Guide."

7. Use the "ciptool(1M)" command to confirm that the IP address of CIP was changed.

   # /opt/SMAW/SMAWcf/bin/ciptool -a

   Note

   For details on the "ciptool(1M)" command, see the manual page describing ciptool(1M).

8. When using ICMP shutdown agent to the shutdown facility, change the registered IP address.

   For ICMP shutdown agent, see "5.1.2.6.2 Using the Shutdown Configuration Wizard" and set again the IP address to be used to check if the node is alive.

   Figure 9.9 ICMP shutdown agent

   

9. Check each of the shutdown facility statuses on the shutdown facility status display screen after changing the IP address registered in the shutdown facility.

   Figure 9.10 Displaying the configuration of the shutdown facility

   

   Shut State

   "Unknown" is shown during normal system operation.

   If an error occurs and the shutdown facility stops the relevant node successfully, "KillWorked" is displayed.

   Test State

   Indicates the state in which the path to shut down the node is tested when a node error occurs. If the test of the path has not been completed, "Unknown" will be displayed. If the configured shutdown agent operates normally, "Unknown" will be changed to "TestWorked".

   Init State

   Indicates the state in which the shutdown agent is initialized.

   To exit the configuration wizard, click Finish. Click Yes in the confirmation popup screen that appears.

   Note

   On this screen, confirm that the shutdown facility is operating normally.
   If "InitFailed" is displayed in the Initial state even when the configuration of the shutdown facility has been completed or if "Unknown" is displayed in the Test state or "TestFailed" is highlighted in red, the agent or hardware configuration may contain an error. Set the IP address again.
