9.3.1.1 Changing the MMB IP Address

9.3.1.1.1 PRIMEQUEST 2000 Series

This section explains how to change the MMB IP address in PRIMEQUEST 2000 series.

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 the 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 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.

9.3.1.1.2 PRIMEQUEST 3000 Series (Except B Model)

This section explains how to change the MMB IP address in PRIMEQUEST 3000 series (except B model).

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 the nodes to stop the shutdown facility.

   # sdtool -e

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

3. On the node in which the IP address was changed, execute the following command to start the shutdown facility.

   # sdtool -b

4. After the shutdown facility started in Step 3, start the shutdown facility on the remaining nodes.

   # sdtool -b

5. 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.

   • Unknown or TestFailed is displayed in Test State.

   In this case, review the hardware settings.

9.3.1.2 Changing the User Name and Password for Controlling the MMB with RMCP

9.3.1.2.1 PRIMEQUEST 2000 Series

This section explains how to change the user name and password for controlling the MMB with RMCP in PRIMEQUEST 2000 series.

Operation Procedure

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

   # sdtool -e

2. 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 multiple nodes, change them for all the nodes.

3. By executing the following command, change the user name and password of MMB information for MMB asynchronous monitoring function. 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]

4. Execute the following command on all the nodes to start the shutdown facility.

   # sdtool -b

5. 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.

9.3.1.2.2 PRIMEQUEST 3000 Series (Except B Model)

This section explains how to change the user name and password for controlling the MMB with RMCP in PRIMEQUEST 3000 series (except B model).

Operation Procedure

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

   # sdtool -e

2. 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 multiple nodes, change them for all the nodes.

3. By executing the following command, change the user name and password of MMB information for iRMC asynchronous monitoring function. 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/clirmcsetup -m mmb -u user-name [-p]

   Example 1: Changing only user name (without changing password)

   # /etc/opt/FJSVcluster/bin/clirmcsetup -m mmb -u user-name

   Example 2: Changing both user name and password, or changing only password

   # /etc/opt/FJSVcluster/bin/clirmcsetup -m mmb -u user-name -p

4. Execute the following command on all the nodes to start the shutdown facility.

   # sdtool -b

5. 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.
