I have a server which is on VMWare ESXi 3.5, I plan to upgrade it to VMWare ESXi v4.
1. I installed the vSphere client with Host Update Facility, but it displays the message "Patching this host version is not supported by vShpere Host Update Utility."
2. I went ahead anyway and put the host into maintenance mode and ran the update, the vSphere Host Update message then becomes "Failed to deploy host upgrade agent".
fyi the server is running on Dell R710, Dual CPU, 32GB Ram, win 2008 STD x64 virtual servers.
