In the event of migrating your old vCenter Server to a new version (or from Windows to the appliance), it may become necessary to first clear out old historical data. Not only will this speed up the migration process considerably, it will also prevent certain issues which may block the migration from completing successfully.

VMWare provided a KB with database scripts which allow you to selectively purge historical data and decreasing the database size: KB 2110031.

The Barracuda VPN Client does not work properly on macOS Mojave: after connecting the VPN, the UI crashes and restarting it immediately makes it crash again. The VPN tunnel itself does work, but other than manually killing the process (kill -9), it is not possible to terminate the tunnel (other than rebooting of course).

An updated version of the client, Barracuda VPN Client 5.0.2.5 for macOS is available which resolves these issues.

Handbrake offers the ability to convert copy-protected DVD's (aka "rip") too. It is not able to do this out of the box, but instead, relies on a specific library called libdvdcss. This library is installed by default when you also use VLC media player, but a version compatible with Handbrake is also available for download.

For Mac OSX, an installer was made available to easily install the library and have Handbrake use it, but due to the write-protection of system folders, introduced with macOS High Sierra, this method no longer works. As a result, it became difficult to use Handbrake. Fortunately, there are a number of workarounds and other methods of installing the library, whic  ...

On Windows Server 2016, when attempting to enter a full edition product key on an evaluation edition, you will get the error: "This edition cannot be upgraded". Fortunately, you can workaround the issue by "upgrading" via DISM (a built-in command-line tool).

Note that you will have to reboot the server when performing the upgrade, so schedule some downtime for it. Also, you cannot only convert full GUI versions of Windows Server. Server Core or Nano Server cannot be upgraded. Additionally, if you have the ADDS role installed, you need to uninstall this role before performing the upgrade.

Start an elevated command prompt, then type in the commands listed below.

First, m  ...

Starting or stopping the SSH service on multiple ESXi hosts can be a tedious job when having to do this via the vSphere (Web)Client. Fortunately, you can also use PowerCLI to start/stop services quickly. With a little scripting, you can expand this to start/stop services on a set of hosts, a cluster, or the entire vCenter.

First, start PowerCLI and make a connection to the vCenter. For automation, you can use something like this (note that you have to add code for credentials, if needed):

if (-not (Get-PSSnapin VMware.VimAutomation.Core -ErrorAction SilentlyContinue)) { Add-PSSnapin VMware.VimAutomation.Core | Out-Null }Connect-VIServer vcenter.domain.local

Once that's done, you can ga  ...

You can easily update your vCenter Server Appliance (VCSA) offline by downloading a product patch ISO and via the CLI.

Download the latest patch from VMware Patch Download Center. Select VC from the Search by Product drop-down menu, then select the correct version (i.e. 6.0 or 6.5). Download the patch ISO and attach it to the VCSA.

Log in to the shell (using SSH or VMRC) and initiate the update:

  1. Stage the ISO updates:
    software-packages stage --iso --acceptEulas
  2. Optionally, you can view the list of packages to be updated:
    software-packages list --staged
  3. To install the updates, run:
    software-packages install --staged

After the update has finished, you will have to reboot the VCSA.
