Rob de Veij just released a minor update for RVTools, 2.3.1. Rob was notified by several users that an error occured while using RVTools. Here is the relevant section from the release notes:
Bug on vDatastore tab fixed: System.InvalidCastException: Unable to cast object of type ‘VimApi.NasDatastoreInfo’ to type ‘VimApi.VmfsDatastoreInfo’.
If you are running RVTools, be sure to pick up the latest version here.
Will RVTools work on accounts that has read-only access to the VC? Aside from the obvious ones that VMware Tools update or disconnect cd-rom/floppy won’t work.
