Cheat sheet

You can install IPMI and IPMItool via yum using the following command:

Make sure that the server is set to start during startup and start the IPMI service.

[root@anm ~]# chkconfig ipmi on
[root@anm ~]# service ipmi start

We have here some IPMItool commands which can be used in day-to-day operations.
