Comment 2 for bug 1791244

In vcenter deployments, recommended procedure to bring a ESXi host out of standby mode:

1. "Resolve Issues" from EAM - will exit the ESXi host from standby mode and power on ContrailVM.
2. If ESXi host is powered on, wait for host to be back up and "Resolve Issues" from EAM post as applicable

In the above procedure, if the EAM looses connection and the agency is deleted, apply the following workaround:

To resolve the issue as described in the bug, restart the ESX Agent Manager service on vcenter server.

Administration -- Deployment -- System Configuration -- Services -- ESX Agent Manager -- Restart

To tack and debug the EAM exception, SR is raised with VMWare - #18932826409
