Re: What happens if an enclosure is configured in OneView and then taken out of OneView?

HP OneView is architected to take into account outages of the management appliance.  If hypervisor host fails, it can be quickly recovered by moving it to another hypervisor host, or letting VMware HA handle the redundancy.  The infrastructure will continue to operate while the appliance is recovered.  The only aspect that cannot be managed are the Server Profiles and VC network configuration as HP OneView is the manager.  You would still have access to the Onboard Administrator and server iLO's.

 

If the VM fails, then it needs to be recovered manually.  The infrastructure again would continue to run just like I stated above.  An appliance backup might be needed, if the appliance VM needs to be redeployed.  This scenario should be extremely rare.
