Create an ISO file with PowerShell!
I received a request at work to transfer 5+gb from the internal network, to a server in the DMZ. Our DMZ networks are locked down, so I cannot copy the files directly. I have the trial version of UltraISO that I’ve used for tasks like this in the past, but it’s limited to 300mb in the trial version. Previously, we’ve…
Handy PowerShell command to stop Task Manager Process!
Have you ever needed to stop multiple processes at once? I use a product by Devolutions called Remote Desktop Manager. If you’re a regular reader of this blog, you probably already know that. When I launch the VMware vCenter Web Client via RDM, I do so via Chrome and it opens the Client Integrated Plugin. The problem is, when I…
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…
vDocumentation: Check Out These Scripts To Automate Your Documentation!
Now that VMworld 2017 US has come to a close, many of the sessions are already up on youtube to watch. One of the ones I watched yesterday was SER2077BU – Achieve Maximum vSphere Stability with PowerCLI Assisted Documentation. My friend, Ariel Sanchez Mora (@arielsanchezmor), and his friend, Edgar Sanchez (@EdmSanchez13), put together these scripts to automatically document your environment.…
Script to disable protocols older than TLS 1.2 and turn off RDP
My InfoSec team came to us asking we disable anything older than TLS 1.2 and turn off RDP on our servers in the DMZ. We don’t allow RDP in the DMZ anyway, and they found that leaving RDP on when not using it poses a security risk. To do this, it involved multiple registry changes. With several servers to do…
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…
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…
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…
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…
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…
