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
ipmi_msghandler module in kernel. ipmi_si module in kernel. ipmi_devintf module not loaded. /dev/ipmi0 does not exist.
If "/dev/ipmi0 does not exist." is displayed, execute the following command.
If "/dev/ipmi0 exists." is displayed, it is not necessary to execute the following command.
# /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.
# /usr/bin/systemctl status ipmi.service
ipmi.service - IPMI Driver Loaded: loaded (/usr/lib/systemd/system/ipmi.service; disabled) Active: inactive (dead)
If "inactive" is displayed in "Active:" field, execute the following command.
If "active" is displayed in "Active:" field, it is not necessary to execute the following command.
# /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
If "disabled" is displayed in "ipmi.service" field, execute the following command.
If "enabled" is displayed in "ipmi.service" field, it is not necessary to execute the following command.
# /usr/bin/systemctl enable ipmi.service
