What do you do when a path to a NFS Datastore goes down?

My QA environment uses Isilon as it’s backend storage platform.  The Isilon share is one large storage volume that is setup with different paths (IPs) to the storage.  This environment has 6 datastores (6 paths).  The other day, we had one of those paths go down, taking down approx 75 VMs with it. I debated attempting to remove the down datastore and then add it back with the same name (with a different IP) but didn’t know what that would

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,

EMC Elect 2016 – Thank you!

Today I was officially named as an EMC Elect 2016, my 2nd year in a row and 3rd overall year in the program.  To say I’m honored and thrilled is an understatement! A while back I remember Duncan Epping saying something on Twitter similar to, “Everyone at VMware should be a vExpert.”  I’m paraphrasing but his sentiment is clear – if you work for a company, you shouldn’t need an award to incentivize you to evangelize that company’s products.  He’s absolutely

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.

Place a vSphere Host into Maintenance Mode via PowerCLI

So, we had two different vSphere hosts, in two different environments, have hardware faults this week.  One had a bad memory module, and the other a bad FAN.  As I launched the VI client for each environment and placed the problem host into maintenance mode, I started to think… “I bet I can automate this!” Depending on how complex your environment, you may or may not find this useful.  For me, I have 6 different production vCenter servers, one QA

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

My First VMworld Experience

            So, VMworld US 2015 was my first time being able to experience VMworld first hand, and not by streaming keynotes and watching recorded sessions months later.  As a VMUG Leader, I’ve experienced VMUG Meetings and UserCons before (both as a leader and a member) but this was a whole different animal! First off, I have to credit my brother, Matt, for helping to guide my VMworld experience, introduce me to different VMworld regulars, recommend
