I've been into VMware for quite a while now. And into storage products also. So it is quite normal that VMware vSAN caught my interest immediately. But it is challenging sometimes, to explain in an simple and easy way, how it works and what the benefits of vSAN are depending on the knowledge of the... Continue Reading →
Just a quick command I used. Maybe it will be useful for someone as well. I thought about the easiest way to check for all active and standby uplink ports on all vSphere Distributed Switch portgroups in my datacenter, for documentation purposes. You could easily check the settings on each portgroup by navigating to the... Continue Reading →
Last week I came up on a situation on my homelab where one of my VMware ESXi host was not responsive and not connected to the vCSA, even though the virtual machines running on it were not affected. Trying to connect to the host's website I received this error: I connected to the host by... Continue Reading →
Using the newly released version vCSA and ESXi 6.7U1, it is possible to manage VMware Tools and VM Hardware updates directly from the HTML5 panel. A few notes from myself, as I was asked multiple time during the last few weeks about the option and how it will be implemented into the HTML5 client. As... Continue Reading →

The appliances on both sides were updated to version 6.5.1.1832 Build 6128217 and the vCenter Server appliances as well as the ESXi hosts were on the latest build at 6.5. The environment was...

Just a quick reference to bookmark, may someone think it's useful. Spending time to rescan HBA's on all hosts in a cluster is time consuming and not worth the work. It is possible to rescan all HBA's with a simple PowerCLI line: Get-Cluster -Name “Clustername” | Get-VMHost | Get-VMHostStorage -RescanAllHba or if you have more... Continue Reading →
First of all, these are all my opinions and thoughts about the journey and preparation towards the VCAP6-DCV Deploy certification. Links provided are already listed on "Unoffical Study Guides" or other blogs, but I will also list them as these were part of my preparation. I was aiming to archive a whole new level of...

I was facing another really annoying issue recently which was quite new for me. While looking for an acceptable solution I came across a website from Lingeshwaran Rangasamy which I do not want to hide as it describes how to fix it in a few steps. Many kudos to @UnixArena. Hope he doesn't mind my... Continue Reading →
