Resolution
Ensure that the backup proxy is in a connected state.
Ensure that the virtual machine does not show VM_name(disconnected) state under vCenter.
Check the connection to ESXi port 902 from backup proxy. Run the following command:
#telnet <Esxi_IP / Esxi_Name> 902If the ESXi/vSphere host should be licensed for vStorage APIs, verify if the VMware license is installed.
For example, for vSphere 6.0:In the vSphere Web Client, select Administration, and under Licensing, select Licenses.
Select the Licenses tab.
In the table, select a license.
Click View License Key.
