Description of problem:
------------------------
Gluster Fencing policies are enabled by default with RHV Manager 4.4, so there is no need to configure anything specific to the topic of FENCING.

So update the chapter-15.2 refers as "15.2. Configure fencing for high availability", modify this chapter as "(Optional) 15.2 Configure Host Power Management"

Content goes like:
" You can configure power management if the host has a supported power management card.The Red Hat Virtualization Manager is capable of rebooting hosts that have entered a non-operational or non-responsive state, as well as preparing to power off under-utilized hosts to save power. This functionality depends on a properly configured power management device."
