How to delete a host entry from RHEV-M database?

Hi,

My self-hosted engine environment contains 2 additional hosts (H2 and H3) for manager's HA and the manager is running on Host H1.
I removed a host(H2) from my self-hosted engine environment through RHV-Manager GUI. Now, it's no longer visible on the manager's GUI but it's still visible from other hosts (Host H3) when I type "hosted-engine --vm-status" on the command line.

One resolution I encountered with, is to remove the host entry from the manager's database. How to do this?

If there is any other way, please explain in detail. Thank you.
