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!
