So, you want to use PowerCLI to do some things with VMware vSphere and you are just getting started. Maybe it’s to run some basic cmdlets and poke around vSphere, for maybe you want to search for attached ISO’s on VM’s, or maybe it’s to run a script to count cores and TiBs for VCF…

In preparation for upgrading Aria Ops, Logs and installing Aria Automation I found I was needing to expand the storage within Aria Lifecycle Manager. No big deal, go into Settings -> and click Extend Storage: Put in the details, and the disk will begin to expand – I’m choosing to expand 20GB additional for some…

Using VIM and seeing a very dark blue hard to read font? Change the default colorscheme to something easier on the eyes…I prefer Koehler. This is what the original color scheme looks like with an example script/file…very hard to read and I don’t like to squint… With using vim, it’s possible to change it anytime…

In the first and second parts of the previous UMDS blogs, I installed UMDS and then configured and setup a repository for vSphere LCM. This worked great, however the download and export process ended up being manual, which is less that desired. I prefer UMDS to automagically download and then export those files, so I’m…

Continuing from the previous blog, where I showed how I installed Update Manager Download Service in my lab, this blog will focus on the setup and configuration of UMDS, using Apache to publish a repository, and finally setting up VMware LCM to use those files as a repository for updates.

UMDS. UMDS runs on Linux, and downloads software metadata, software binaries, and notifications that may not…

Are you seeing the below error when connecting to a vCenter server? If yes, it’s easy and simple to resolve this issue. I’m on my local Windows OS machine using Chrome browser, so I’m going to install this locally. In a production environment with a larger deployment, best practice would be to install using the…

So, I must admit, I was in a hurry and messed up when removing a datastore from my vSphere environment. Now I have an inaccessible, and orphaned, datastore in vCenter…meaning the datastore is gone on the storage side, and now I also cannot delete it from vCenter: When attempting to delete from vCenter I receive…

VMware vCenter Server 8.0U2 was released on 9/21/2023 [Release Notes] [Download] and it’s time to upgrade the vCenter in my lab. There’s a couple of different ways to to this, and I wanted try try using the Reduced Downtime Upgrade (RDU) function new to vSphere v8U2. Let’s give it a try! What exactly is Reduced Downtime…

A very common task I run into is checking and verifying what version a build number of vCenter, ESXi and Tools (and Horizon on occasion) are installed in an environment, including my own lab, so I wanted to put a few helpful links out there. Below are links to VMware KB’s that list out the…

Latency sensitivity of a virtual machine can be changed to optimize the scheduling delay for latency sensitive applications and workloads. This feature was rolled out with vSphere 5.5, and the feature is still available as of right now in vSphere 7U3o and vSphere 8.x. As a sysadmin and/or user of vSphere… what does this really…

Firefox is pre-installed, but I prefer Chrome – let’s install Chrome. This is maybe a long enough section to create a new blog, but let’s go ahead and cover it here. This method works for Linx Mint and any other distro that works with .deb packages. We will also use Terminal (command line) which I…
