8.8.1 Changing the MMB IP Address

This section explains how to change the MMB IP address.

Note

• Change the MMB IP address on each node.

• Repeat the operation procedure described below to change more than one MMB IP address.

Operation Procedure:

1. Execute the following command on all nodes to stop the shutdown facility.

   # sdtool -e

2. Execute the following command on the node in which IP address is changed to stop MMB asynchronous monitoring daemons.

   # /etc/opt/FJSVcluster/bin/clmmbmonctl stop

3. Change the IP address according to the MMB procedure.

4. On the node in which the IP address was changed, execute the following command to start MMB asynchronous monitoring daemons and the shutdown facility.

   # /etc/opt/FJSVcluster/bin/clmmbmonctl start
   # sdtool -b

5. After the shutdown facility started in Step 4, start the shutdown facility on the remaining nodes.

   # sdtool -b

6. Execute the following command on all nodes and check that the shutdown facility operates normally.

   # sdtool -s

   Note

   There is a possibility that the mistake is found in the configuration setting of the hardware when displayed as follows though change of the setting of the shutdown facility is completed.

   • "InitFailed" is displayed as the initial status.

   • "Unknown" or "TestFailed" is displayed as the test status.

   In this case, review the configuration setting of the hardware.
