How to cleanup disk previously used by vSAN 6.x

In the VCSA Web Client, there is a function called Erase partitions under Storage Devices, that allows you to erase and remove all partitions on the local hard disk(s). However, sometimes when you try to erase partitions, you are presented with the error “Cannot change the host configuration“, and the partitions are not removed.

How to upgrade vCSA and PSC to the latest version – the easy way

VMware suggested way of upgrading the vCSA and PSC to the latest software version is not the easiest way to do it. It’s actually not the upgrade, rather a new installation and then backup and restore of the current configuration. Luckily, there is a lot easier way of doing the upgrade and it takes just about 10 minutes. To do so, first, you must download a slightly different ISO image.  Log in to my VMware and go to Product Patches page. Enter your version of the vCSA and download the FP ISO file, in my case VMware-vCenter-Server-Appliance-6.5.0.5500-5318154-patch-FP.iso Continue reading “How to upgrade vCSA and PSC to the latest version – the easy way”
