E.3.1 Startup Configuration for the IPMI Service

Perform the startup configuration for the IPMI service so that Configuration Update Service for SA can use the IPMI service when obtaining the BMC or iRMC IP address of the server.

In the RHEL6 environment

Starting the IPMI service
Execute the following command on all the nodes to check the startup status of the IPMI service.
```
# /sbin/service ipmi status
```
Execute the following command on all the nodes in which the IPMI service is not activated to start the IPMI service.
```
# /sbin/service ipmi start
Starting ipmi drivers:                                     [  OK  ]
```
Setting the run level of the IPMI service
Check the current run level of the IPMI service on all the nodes.
```
# /sbin/chkconfig --list ipmi
ipmi            0:off   1:off   2:off   3:on    4:off   5:off   6:off
```
Note
Copy the value when the run level is set to "on." The above example shows that the run level is 3. This value is required for canceling this service and restoring the environment.
Execute the following command on all the nodes to read the IPMI service on startup.
```
# /sbin/chkconfig ipmi on
```
Information
You can set "on" to run levels only that you want to activate this service. In this case, specify run levels in the range from 2 to 5.

In the RHEL7 environment

Starting the IPMI service
Execute the following command on all the nodes to check the startup status of the IPMI service.
When the content of "Active:" item is "inactive", the IPMI service has not been started, go to Step 2.
When the content of "Active:" item is "active", the IPMI service has been started, go to Step 3.
```
# /usr/bin/systemctl status ipmi.service
ipmi.service - IPMI Driver
Loaded: loaded (/usr/lib/systemd/system/ipmi.service; disabled)
Active: inactive (dead)
```
Execute the following command to start the IPMI service on all the nodes where the IPMI service has not been started.
```
# /usr/bin/systemctl start ipmi.service
```
Enable the IPMI service.
Confirm that the IPMI service is "enabled" on all the nodes.
```
# /usr/bin/systemctl list-unit-files --type=service | grep ipmi.service
ipmi.service                                disabled
```
As "disabled" is displayed in the above situation, you need to execute the following command on all the nodes to read the IPMI service on startup.
If "enabled" is displayed, it is not necessary to execute the following command.
```
# /usr/bin/systemctl enable ipmi.service
```
