This host has no isolation addresses defined as required by vSphere HA

Advertise here with BSA


I had a comment on one of my 2-node vSAN cluster articles that there was an issue with HA when disabling the Isolation Response. The isolation response is not required for 2-node as it is impossible to properly detect an isolation event and vSAN has a mechanism to do exactly what the Isolation Response does: kill the VMs when they are useless. The error witnessed was “This host has no isolation addresses defined as required by vSphere HA” as shown also in the screenshot below.

This host has no isolation addresses defined as required by vSphere HA

So now what? Well first of all, as mentioned in the comments section as well, vSphere always checks if an isolation address is specified, that could be the default gateway of the management network or it could be the isolation address that you specified through advanced setting das.isolationaddress. When you use das.isolationaddress it often goes hand in hand with das.usedefaultisolationaddress set to false. That last setting, das.usedefaultisolationaddress, is what causes the error above to be triggered. What you should do in a 2-node configuration is the following:

  1. Do not configure the isolation response, explanation to be found in the above-mentioned article
  2. Do not configure das.usedefaultisolationaddress, if it is configured set it to true
  3. Make sure you have a gateway on the management vmkernel, if that is not the case you could set das.isolationaddress and simply set it to 127.0.0.1 to prevent the error from popping up.

Hope this helps those hitting this error message.

Unexpected VMware Update Manager (VUM) baseline creation failure. Please check vSAN and VUM logs for details.

Advertise here with BSA


I had a customer asking about an error they received after upgrading to 6.7 U1. The message they saw was the following: “Unexpected VMware Update Manager (VUM) baseline creation failure. Please check vSAN and VUM logs for details.” I had seen some folks on VMTN also complaining about this a couple weeks ago, and I knew a KB article was in the makings. Just to ensure people know where to get it, and to make it easier for myself to find it I want to share KB 60380 with you. I am not going to copy/paste the resolution, as I prefer to have the KB being leading on this, just in case it gets updated. I don’t want to provide potentially outdated info. So just go to KB 60380 if you are hitting the “Unexpected VMware Update Manager (VUM) baseline creation failure. Please check vSAN and VUM logs for details.” error.

Disable Dark Mode for Outlook in OSX?!

Advertise here with BSA


Yes, after the latest update MS Office is now also capable of supporting the OSX Dark Mode. Nice, but rather annoying for MS Outlook I must say, the dark mode just makes reading the different panes very challenging. I went looking for an option in the UI that allowed me to change the default, I couldn’t find it, unfortunately, but I did find a way to disable it through the command line. For MS Outlook, in particular, this is how you do it:

defaults write com.microsoft.Outlook NSRequiresAquaSystemAppearance -bool yes

You can do this for other apps as well if you want, simply change the identifier string of Outlook (com.microsoft.Outlook) with the string of the app you want to disable it for. If you don’t know the string you can do the following to find it:

osascript -e 'id of app "Outlook"'

In the above example, I am looking for the identifier of Outlook, but this could be “Spotify” or anything else as well of course. Figured I would share this, as I found myself searching for half an hour.
