engine-setup should detect hosted-engine environment. Once detected, it should: 1. Provide correct installation guide - SHE guide in this case. https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.6/html/Self-Hosted_Engine_Guide/chap-Maintenance_and_Upgrading_Resources.html 2. Do not proceed, if environment is not in global maintenance. Version-Release number of selected component (if applicable): 3.6.5. Running engine-setup on HE, while not in global maintenance, will result in fencing the VM during the upgrade and lead to irrecoverable environment.
