Script to backup your vCenter DRS Rules

I was thinking yesterday, I have a script that I run on a monthly basis to backup my vDS configs…  Shouldn’t I also have something that does the same for my DRS rules?  So, I wrote a script that I can schedule to run on a weekly/monthly basis to backup my DRS rules. I have multiple vCenter servers, so I used an array to connect to each one and then exported the rules for each cluster within those vCenters. The

One of my favorite tools – Remote Desktop Manager by Devolutions

One of the tools I’ve been using for many years now is called Remote Desktop Manager by Devolutions.  Based on the name, you’d think it’s just another RDP tool, but it’s much MUCH more! There are 2 versions of the product.  There is a FREE version, which gives you limited functionality, and an ENTERPRISE version for full functionality.  There is also a RDM Server as well, but I have no experience with that. The free version lets you setup RDP

Adding a PowerShell Windows Update Script to my VMware Customizations

In my environments, we typically convert the templates to Virtual Machines once a quarter so we can install Windows Updates.  This means, there could be a number of patches to install if you’re 2+ months out from the last time they were updated.  So I decided to use a PowerShell script that my coworker wrote to do Windows Updates and run it during the Run Once phase of the vCenter Customizations. Typically, I have my customizations set to automatically login

My Experience Upgrading vCenter to 5.5 Update 3b

I recently upgraded my vCenter from 5.5 Update 2, to 5.5 Update 3b.  As this is a fairly straightforward process, I didn’t expect anything to go wrong.  I proceeded through all the main components and once completed, attempted to connect to vCenter…  I found I couldn’t connect.  Further investigation found that the service would not start! Attempting to start the VMware Virtual Center service gave me: We also found that when we attempted to start VPXD manually from a command

Patching VMware ESXi Hosts via PowerCLI!

*** Updated 5/17/2017 – See below *** This year, I’m trying something new…  Anything that I have to do more than 2-3 times, I’m going to attempt to automate it! In keeping with this mantra, I recently had a task come across my plate to patch the 20+ ESXi Hosts in one of my production environments.  Along with installing the latest Host Updates, I also wanted to upgrade Dell’s Open Manage Server Administrator to the latest version. In the past,

Display list of Multiple vCenter Servers to connect to in your PowerCLI Scripts

If you’re company anything like mine, you probably have multiple vCenter servers in your environment.  They may be linked, they may not.  In my environment, we have 4 vCenter servers we consider Production, even though one is for QA, and we have a lab environment. Normally, I just connect to vCenter manually in PowerCLI before I run a command/script to make a change, run a report, etc.  But then I got to thinking, wouldn’t it be easier if I just

Migrating Roles & Privileges from an old vCenter to a new vCenter using PowerCLI

So we’re finally upgrading an old environment running vCenter 4.0 to a new vCenter running 5.5.  Instead of attempting an upgrade, we’re building new.  As it’s a new build, we had to find a way to migrate the roles & privileges to the new vCenter. I have done this in the past utilizing the “Cheap Disaster Recovery” scripts from Gabe’s Virtual World.  You can find Gabe on twitter here! For some reason, the export script didn’t work for me here.

You should backup your VDS Configs with PowerCLI

So, another vExpert that I follow on twitter (@h0bbel) recently had an issue in his home lab where he cut power to his lab, and his vDS lost all the portgroup names.  Seeing this post made me think, “I should probably backup MY vDS configs too, as my backups were pretty old! Here are some PowerCLI commands that I found that could help you backup your config!   Also, here is the blog post I used for this script, written by

PowerCLI Script to change the DRS Slider

So, I have a cluster of hosts that makes up our QA Environment.  As with most QA environments, it’s tight on resources and very over-subscribed.  On a regular basis, I have to move our DRS Slider to be more aggressive, RUN DRS to refresh recommendations, and then move the slider back.  This allows DRS to rebalance the cluster.  Today, I decided to script it. I made use of a script that @lucd22 posted (http://vmw.re/1EQCDkn) to change the DRS Migration Threshold

PowerCLI Script to migrate VMs from one vCenter to another

Hey everyone, this is another guest post from Ben Liebowitz, Matt’s brother. Before I get into the script, I’ll give you some background…  We are working on migrating VMs off of our vSphere 4.1 environment to our new vSphere 5.5 environment.  The 4.1 environment is using the Nexus 1000v Virtual Switch while the 5.5 environment is using a vDS switch. We found the easiest way to migrate the VMs was to remove them from inventory on the 4.1 side and
