Suggestions for improvement: Add some instructions or notes to shutdown and boot RHUI servers. I think that some cases require attentions of the order of shutdown and boot RHUI servers. a. If CDS double as Gluster Storage, RHUA must shutdown first, then CDS in rotation, and CDS must boot first and then RHUA at the end. b. If external NFS storage is used, we don't need to take of the order to shutdown and boot servers, AFAIK. c. If RHUA is the NFS storage, RHUA must shutdown last and boot first by necessity.
