openBMC Usage Basics

OpenBMC is an open software framework to build a complete Linux image for a Board Management Controller (BMC)

I expect increasing number of openPOWER based servers moving towards openBMC vs conventional and proprietary IPMI implementations.

In my effort to familiarize readers with openPOWER servers, I wanted to write about some basic commands on using openBMC, specifically on how to control host via openBMC. 

Once you ssh into openBMC Linux:

To power off the host from BMC:

obmcutil poweroff

 

To power on the host from BMC

obmcutil poweron

 

To get remote host console within the BMC SSH Session

obmc-console-client

 

If you are debugging something on the host, I suggest you have 2 parallel ssh sessions to the BMC and use one to control power / look at logs and the other to look at host console.

To get remote host console directly without logging into the BMC:

ssh -p2200 root@<BMC IP>
