Migrating a WSFC with RDM’s to a different ESXi host cluster in vSphere 8

/by

Sometimes there are migration situations that aren’t that common and will set you out on a journey in search of the correct migration procedure. This happened to me when a customer had two ESXi host clusters, one for development and test, and one for acceptation and production. When the time came for the hardware to […]

Per-VM EVC blocks enabling EVC on the cluster

/by

VMWare Enhanced Vmotion Compatibility (EVC) has been around for a long time. But since version 6.7 of vSphere (minimum hardware version 14), VMWare extended the EVC possibility from hosts to VM’s. This is great because with Per-VM EVC the EVC mode becomes a VM attribute and is no longer dependent on a specific processor generation […]

High Availability errors when upgrading vSphere cluster with Image Profiles

/by

When migrating to a new version of vSphere (in this case from vSphere 7 to vSphere 8) and using image profiles in combination with new hardware, you will get and error that the hosts cannot join the HA configuration. The errors range from “Unreachable” and “Retrying” to “Operation timed out”. We ordered new hosts to […]

Changing the update mechanism from baselines to an image profile fails with an error

/by

“Failed to verify whether cluster contains payload from unsupported solution(s)”. Well there is an error you don’t see every day. And if you are here reading this, you are one of the few who have a misconfiguration in your network infrastructure. Let’s start at the beginning. VMWare will stop the support for updating hosts with […]

VMware vCenter works with LDAPS but logins are invalid

/by

As a good VMware administrator you configured your new vCenter Server Appliance (VCSA) with LDAPS, as Integrated Windows Authentication (IWA) is deprecated by VMware (https://kb.vmware.com/s/article/78506). Everything works fine, but after just a few days none of the administrators can login anymore and get to see: “Invalid credentials”. So you login as administrator@vsphere.local to see what […]

Intune and the New Microsoft Store

/by

About a year and a half ago, Microsoft announced that they would be closing the Microsoft Store for Business in the second quarter of 2023. On its page there was a banner with a link to a blogpost about their new strategy (https://techcommunity.microsoft.com/t5/windows-it-pro-blog/evolving-the-microsoft-store-for-business-and-education/ba-p/2569423) Unfortunately it wasn’t clear what we could expect and how to move […]

Setting up a SFTP server on Windows Server 2022

/by

Nowadays the process for setting up a SFTP under Windows is fairly simple. But there are still some things that won’t go that easy and will give you strange errors and can cost you a lot of time. Especially when you want to use Active Directory authentication and a network share as the home folder. […]

Getting rid of IOS Apps in Intune

/by

When your Intune instance is coupled with Apple Business Manger (ABM) you can use the Volume Purchase Program (VPP). This is ideal for buying and distributing applications to your IOS devices in Intune. Unfortunately when you have no longer use for an installed application and you want to get rid of it, the process is […]

vMotion: A general system error occurred

/by

It’s always nice to have a general error getting thrown in your face. It gives you absolutely no indication as of where something went wrong. I’ve had this pleasure in the past week. I was just minding my own business moving some VM’s around, when suddenly vCenter said “A general system error occurred” and my […]
