Updating Dell Firmware/BIOS en mass

We recently ran into an issue where we had to update the Firmware & Bios on a bunch of Dell servers.  As these are VMware hosts, we couldn’t just run the Dell System Update Utility, as I would on a normal Windows host.  My coworker, @bspagna, and I decided to look at doing this via the iDRAC. Prerequisites:  Dell Repository Manager, a TFTP Server (like Solarwinds Free TFTP Server) First, we used Dell Repository Manager (Data Center Version) to build

PowerCLI Script to Check Host Over-commitment Percentage & Ratios

At my previous employer, we had a Dev/QA vSphere environment that was very over provisioned.  The environment had lots of CPUReady issues with VMs having to wait for CPU time, which caused things to be slow, etc.  We knew this but the application teams didn’t understand.  I ended up writing a PowerCLI script to check the CPU overcommitment and sent the results to my manager who was able to go to the application team’s management and get them to clean

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

Running the vSphere Web Client via Remote Desktop Manager

As you may have seen, I really like a tool from a company called Devolutions called Remote Desktop Manager.  I use it to manage my RDP sessions, Credentials, SSH sessions, as well as to manage my iDRAC/iLO connections.  I also have it manage my connections to my VMware environments.  For the environments that support the VI Client, I have those setup here as well as connections to the vCenter Web Client! First, you have to make sure you have the

PowerCLI Script to create new vDS Portgroups

We deployed new hosts into one of our office locations.  Because these hosts would have different number of uplinks as well as use a LAG group instead of normal dvUplinks, we decided to create a new vDS Switch.  Then, we needed to re-create all the portgroups as well.  I figured, instead of manually adding 15-20 portgroups, I’ll automate it.  I used this blog post as reference to do some of the work, and added the LAG and uplink changes.

Disabling FCOE on vSphere 10gb NICs per VMware KB 2130092

So, we recently had an issue with some of our Dell blade vSphere hosts.  Seems they all crashed (PSOD) at the same time (6 nodes across 2 different clusters).  After submitting the log bundles and Dell TSRs, support recommended, along with upgrading drivers & firmware (the support go to!) that we remove FCoE from the NICs (as it’s not being used).  VMware said the FCoE messages in the logs was just “log spam” and not anything they felt would have

Creating shortcuts for PowerCLI that automatically log you in.

So, I started a new job a couple of months ago and we have multiple vCenter environments.  My friend & temporary co-worker, Brian Spagna (@bspagna) and I both wanted to have shortcuts to launch PowerCLI windows and have a different background color for each to easily identify which environment we were in.  We thought it would be cool to have it automatically connect to it’s respective vCenter also! I recommend you upgrade to the latest version of PowerCLI (6.5.1) for

Disabling WiFi Power Management Permanently for Raspberry PI 3 with Raspbian Jessie

One problem I found when playing with my Raspberry PI3 (running Raspbian Jessie), is that the WiFi would drop after a certain amount of inactivity.  This was problematic at VMUG Meetings, and due to lack of having a screen to connect, I was forced to power-cycle the unit to get it back online.  After doing some googling, I found the built-in WiFi for the Raspberry PI 3 had some Power Management features, which were enabled by default. You can check

Script to delete folder older than 30 days… by Name

I had a need, on one of my file servers, to delete some data that was older than 30 days, to clear space.  This would need to be a re-occurring task, so what better way to accomplish it than to script it! Here’s the rub…  The folders are each in a YYYYMMDD format (ex: 20170115), yet the content in the folders could be dated other than the folder name itself.  For instance, there could be a folder (say 20170626) that

Setting up the Raspberry PI 3 As A VMUG Registration System

Sometime in 2016, there were some posts in the VMUG Leader Workspace on vmug.com by Patrick Stasko (@PatrickStasko), from Cleveland VMUG, about setting up Raspberry PI as a VMUG Registration System.  I was very intrigued and decided to look into doing it for NJ VMUG! We purchased the following items: Raspberry PI 3 Model B Motherboard http://amzn.to/2l8bFjk CanaKit 5V 2.5A Raspberry PI 3 Power Supply/Adapter/Charger http://amzn.to/2jS61gh Official Raspberry PI 3 Case – Black/Grey http://amzn.to/2kHJpmN Addicore Raspberry PI Heatsink Set for
