Check the connection details
The VMware Server address is entered on the VMware Server | Connection Details screen.
From the Spotlight Client
- Click Configure | Connections.
- Right click on the VMware connection and select Properties.
- Check the connection details.
- Click Test to test the connection.
VMware Server address
Check the address is a valid IP address or hostname of the ESX server or VirtualCenter server.
If you have a VirtualCenter server then connect to that in preference to the ESX host. That way if the virtual machine migrates from one host to another the VirtualCenter server can still be interrogated for data for the virtual machine.
Authentication
Verify the user has at least a read-only role for the ESX server or VirtualCenter server.
Hyper-V Server availability
Verify the VMware Server is available and accessible over the network. Verify TCP port 135 is open.
The alarm will clear automatically if the error is due to the service being down or network problems and the error condition goes away.
