Last week I upgraded a customers vSphere 5.5 environment to vSphere 6. Everything went smooth, upgraded VSAN to v2 and even Veeam picked up the new vCenter 6 appliance without a hitch. But when I opened the vSphere Client (yeah I still use it sometimes… sorry for that) there were two plugin errors.
VMware vCenter Storage Monitoring Service
The plug-in failed to load on server(s) xxxxx due to the following error: Could not load file or assembly ‘VI, Version=126.96.36.199, Culture=neutral, PublicKeyToken=xxxxx’ or one of its dependencies. The system cannot find the file specified.
This is an expected behaviour in VMware vCenter 6 because the “Storage Views” tab is no longer available in the vSphere 6.0 Client.
The cure is easy, just uninstall the old vSphere 5.x client(s) and the “error” is gone!
The following error occurred while downloading the script plugin from https://xxxxx:6502/vmw/rbd/extensions.xml: The request failed because of a connection failure. (Unable to connect to the remote server)
