Increasing the amount of vCPUs in ESXi is a simple admin task when working with a single or low number of virtual machines. However, performing this on a large number of virtual machines can be an intensive task.
This article is about my use case and how I resolved this with a script, which can be found at the bottom.
At my current assignment, I got busy with the replacement of an existing vCenter Server and migration of all linked objects. This included migrating the vSphere Distributed Switch Port Group objects, settings and permissions.
Exporting the vSphere Distributed Switch configuration is an easy-to-do job using the GUI. However permissions are not included. This post is dedicated to the script I wrote to export and import these permissions.
Last week I got busy with upgrading four VDP appliances for a customer. I’ve come across quite some challenges and issues during this task that I’d like to share these with you in case you are facing the same task.
While new versions of vSphere are being released and deployment methods have been changed, it’s currently not so straight forward to deploy a vSphere lab inside Fusion and Workstation. This due to the fact that there is no OVF-based vCenter Server Appliance install available anymore (as of vSphere 6) and there is some manual fiddling required to make this work. This article will describe the steps you need to take for deployment.
Starting with vSphere 6, components for license, certificate management and SSO are being handled by the PSC (Platform Services Controller). This new part of a vSphere installation can be configured to be highly available.
I came across an issue where a fresh installation of vCenter Server 6.0 using an external high availability deployment of PSC would fail with a certificate or invalid credentials error. This article describes the issue and how it was solved.
A while ago I was asked to aid in some performance issues in a customers’ vSphere environment. This article is all about troubleshooting your own environment using esxtop in combination with a tool called PAL (Performance Analysis of Logs) which can generate a report including alerts and graphs.
