Cool Tool : RVTools version 3.8 is now available for download

Thanks to Rob de Veij (@rvtools) for developing RVTools and sharing with the community for free of cost. This tool does a great job of fetching loads of information from the Virtual Infrastructure and saves lot of time for the VI administrator, otherwise we need to run multiple script to fetch similar data.

RVTools is a windows .NET 2.0 application which uses the VI SDK to display information about your virtual machines and ESX hosts. Interacting with virtual center. RVTools is able to list information about VMs, CPU, Memory, Disks, Partitions, Network, Floppy drives, CD drives, Snapshots, VMware tools, Resource pools, Clusters, ESX hosts, HBAs, Nics, Switches, Ports, Distributed Switches, Distributed Ports, Service consoles, VM Kernels, Datastores, Multipath info and health checks. With RVTools you can disconnect the cd-rom or floppy drives from the virtual machines and RVTools is able to update the VMware Tools installed inside each virtual machine to the latest version.

ESXi 5.5 host error “vim.fault.NoHost” during rescan.

Summary : During my preparation for the VCAP DCA exam and upon a rescan activity on the host it error out “vim.fault.NoHost”. I had not seen this error before in my lab nor in production.

Solution: I googled and found few useful links, they have occurred interestingly in the older version of ESX and also during an Host upgrade activity. A simple reboot did not fix the problem for me, so the solution is to get the host in to maintenance mode, disconnect and re-connect the host to the cluster, remember this is my lab host so I can play around it with it. This fixed the issue for me, if you still face the same issue. Remove the host from the cluster and add it back to the cluster, remember that by removing the host from cluster you would lose the inventory stored for the ESXi host. 🙂
