I finally have a Home Lab!!

I’ve been wanting a home lab for quite a long time!  A few years ago, on an old PC, I used AutoLab to deploy a home lab. It used the internal HD in my PC to automatically deploy 2 nested hosts inside VMware Workstation, along with a virtual switch VM, a NAS VM, etc.  The PC only had 16gb of ram and a 3TB SATA HD.  It worked, but it was PAINFULLY slow!  A few months later, my OS crashed and

Do you have Cisco Switches? Are you using CDP?

In my office, we use Cisco gear for networking. Cisco has it’s own protocol called the Cisco Discovery Protocol (CDP). CDP allows you to identify information about the device you’re connected to. Be it from a server to see what port you’re plugged into on the switch, or from the device!  There’s a program for Windows called CDP Monitor that will do this too.. It’s VERY handy, esp if you’re dealing with a physical server and trying to trace the

Teach your co-workers to lock their PCs with the help of a harmless prank!

The goal of this is to teach your co-workers to be more security conscious and LOCK THEIR PC when they walk away from their desk.  Locking your PC stops unauthorized people from accessing your PC, viewing a document that has sensitive data, AND playing a prank such as THIS!  This is especially important when you have access to sensitive data, or better yet, administrative rights! My coworker, @bspagna, came across a LinkedIn Blog post and we started doing this almost

Is Your Flash Plugin Crashing with the vSphere Web Client?

I had this problem recently.  No matter what browser I used, I couldn’t get past the login screen of the vSphere Web Client.  My PC had upgraded to Flash Player 27.0.0.170 a few days ago.  I attempted to uninstall this version and install a previous one with no success.  But after doing some research, I found a KB Article from VMware. The first step was to uninstall Flash Player cleanly.  I found the link below which allowed me to download

Using PowerCLI to Create a Local Scratch Partition

My company recently purchased some Dell Servers with ESXi installed to local SD cards. The issue we had was that the 8gb SD cards that came with the server and there wasn’t enough space on the cards for a scratch partition.  We ordered the servers with a single 300gb HD in order to get the RAID controller, so we decided to use that drive to store a scratch partition. The first step in the process, was to convert the drive

PowerCLI script to forcibly delete a Datastore that is reported as in use.

Have you ever tried to delete a datastore and get an error saying the Datastore is in use? You browse the datastore and see nothing on it. The pre-checks when you unmount it all pass, yet you cannot delete it. We had this problem. VMware support directed us to delete the partition using the partedUtil command, but I didn’t like the possibility of human error in doing it their way. I wrote a PowerCLI script that performs the following. 1.

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
