Chapter 8. Reinstalling an Existing Host as a Self-Hosted Engine Node
You can convert an existing, standard host in a self-hosted engine environment to a self-hosted engine node capable of hosting the Manager virtual machine.
When installing or reinstalling the host’s operating system, Red Hat strongly recommends that you first detach any existing non-OS storage that is attached to the host to avoid accidental initialization of these disks, and with that, potential data loss.
Procedure
-
Click
and select the host. -
Click
and . -
Click
. - Click the Hosted Engine tab and select DEPLOY from the drop-down list.
- Click .
The host is reinstalled with self-hosted engine configuration, and is flagged with a crown icon in the Administration Portal.
After reinstalling the hosts as self-hosted engine nodes, you can check the status of the new environment by running the following command on one of the nodes:
# hosted-engine --vm-statusIf the new environment is running without issue, you can decommission the original Manager machine.
