[ovirt-users] OVirt Engine Server Died - Steps for Rebuilding the Ovirt Engine System

Full disclosure here.....I am not an Ovirt Expert. I am a network Engineer that has been forced to take over sysadmin duties for a departed co-worker. I have little experience with Ovirt so apologies up front for anything I say that comes across as stupid or "RTM" questions. Normally I would do just that but I am in a bind and am trying to figure this out quickly. We have an OVirt installation setup that consists of 4 nodes and a server that hosts the ovirt-engine all running CentOS 7. The server that hosts the engine has a pair of failing hard drives and I need to replace the hardware ASAP. Need to outline the steps needed to build a new server to serve as and replace the ovirt engine server. I have backed up the entire /etc directory and the backups being done nightly by the engine itself. I also backed up the iscsi info and took a printout of all the disk arrangement . The disk has gotten so bad at this point that the DB won't back up any longer. Get fatal:backup failed error when trying to run the ovirt backup tool. Also the Ovirt management site is not rendering and I am not sure why. Is there anything else I need to make sure I backup in order to migrate the engine from one server to another? Also, until I can get the engine running again, is there any tool available to manage the VMs on the hosts themselves. The VMs on the hosts are running but need a way to manage them if needed in case something happens while the engine is being repaired. Any info on this as well as what to backup and the steps to move the engine from one server to another would be much much appreciated. Sorry I know this a real RTM type post but I am in a bind and need a solution rather quickly. Thanks in advance.
