If your Host is stale and is having thr SPM role -> some tasks will fail.Also, 
the VMs on such host won't be recovered unless VM HA is enabled (with storage 
lease).
For prod, I would setup that.Keep in mind that the fencing is issued by another 
host in the cluster, so you need minimum 2 hosts in a cluster before starting 
setup & test.

Everybody, hi:

I would like to ask, after the configuration of power management on the host, 
under what circumstances will work? 

That is, when does the engine send a request to the IPMI module to restart the 
power supply?

  

Is it necessary to configure power management modules in the production 
environment? 

Are there any risks?

  

Thanks!
