9.3.1 Changing MMB Settings

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:

Execute the following command on all the nodes to stop the shutdown facility.
```
# sdtool -e
```
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
```
Change the IP address according to the MMB procedure.
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
```
After the shutdown facility started in Step 4, start the shutdown facility on the remaining nodes.
```
# sdtool -b
```
Execute the following command on all the nodes and check that the shutdown facility operates normally.
```
# sdtool -s
```
Note
There is a possibility that the hardware settings are not correct when any of the following statuses are displayed though changing the settings of the shutdown facility is completed.
- InitFailed is displayed in Init State.
- Unknown or TestFailed is displayed in Test State.
In this case, review the hardware settings.

This section explains how to change the user name and password for controlling the MMB with RMCP.

Operation Procedure

Execute the following command on all the nodes to stop the shutdown facility.
```
# sdtool -e
```
According to the procedures of MMB, change the user name and password to control MMB by RMCP. If you change the user name and password for several nodes, change them for all the nodes.
By executing the following command, change the user name and password of MMB information for MMB shutdown facility. If the user name and the password are to be changed on multiple nodes, change the values on all the nodes to be changed.
```
# /etc/opt/FJSVcluster/bin/clmmbsetup -m [-u user-name] [-p]
```
Execute the following command on all the nodes to start the shutdown facility.
```
# sdtool -b
```
