New vRO and PowerCLI Automation Training

A lot of the projects that I work on have an element of automation to them and I’ve been asked a few times by customers if there is a training course available that will help them get started in understanding vRO and VMware’s PowerCLI cmdlets and how they can be used. Whilst there have been courses available in the past, there is a new one that reads a bit like “Doing my job 101”. It goes by the catchy title of “Data Center Automation with vRealize Orchestrator and vSphere PowerCLI“. Looking at the outline, the important stuff is there. Understanding, using and navigating the vSphere API (useful for both PowerCLI and vRO). PowerCLI basics and more advanced uses. vRO Basics and workflow creation / design. So, if you’re looking to get started with vRO or PowerCLI and use one or […]

Review: Learning PowerCLI

Unless you’re new to vSphere, you’ll probably have heard about PowerCLI. You may already be using it regularly or perhaps you’ve found the occasional use for it and used one or more of the many excellent scripts that can be found on the internet. Either way, unless you’re an advanced user (or even a guru) of PowerCLI, there’s a book that’s been released recently that could be worth a look. “Learning PowerCLI”, by Robert van den Nieuwendijk, was released just a few weeks ago from publishers Packt Publishing. The author has posted many times on his blog with useful scripts, one-liners and tips for using PowerCLI in the past. Several times an issue that I’ve had has lead me to his blog so I was very interested to see if his knowledge and experience had translated well into book form. […]

vOpenData – Shared Virtual Infrastructure Statistics

Whether you love or loathe VMware and their products, one area that you can’t fault is the community that’s built up around them. In that community blood, sweat, tears and a dash of brilliance have produced many amazing things. vOpenData looks like it could be one of them. vOpenData is the brainchild of Ben Thomas and was built with William Lam and assistance from several other VMware community members. Essentially it is a public database of VMware Virtual Infrastructure statistics / configurations. Users download a script that collects some anonymous data about their infrastructure. Once uploaded and added to the database, the data contributes to a plethora of publicly available statistics. At the time of writing there are over 50,000 VMs in the database. The average VMDK size is just over 70Gb. For me, as a techie / evangelist / […]

Do my ESXi hosts have the same VLANs?

In a small vSphere environment that I’ve recently been working on, I started to notice that some of my VMs were disappearing off the network from time to time. Reboots of the VM didn’t seem to fix the issue but a quick vMotion of the VM to another host did. If you haven’t figured it out yet, one of my hosts was missing a VLAN and VMs connected to a certain portgroup were affected whenever they ran on the host. vSphere will warn you if a host that you’re trying to migrate a VM to doesn’t have the right portgroup and host profiles (if you’re using Enterprise Plus licensing) will alert you to the fact that a portgroup isn’t configured with the right VLAN ID but nowhere in vSphere will you get an alert if a required VLAN is not […]

PowerShell Primer

A few times in the last few weeks I’ve been asked if it’s worth learning PowerShell. My answer is always “yes”. Rather than repeat myself too often I thought I’d make a post out of it.

But first, an apology. I met a chap at vBeers in London about 6 weeks ago. His background was more UNIX than Windows but he recognised that PowerShell was something that he’d have to learn a bit about. At the time I did promise to send him a few useful links to get started. As you might have guessed, I didn’t do it.

So… Jeff, I’m sorry.

For the benefit of Jeff and anyone else, here are some places to start when it comes to PowerShell and also PowerCLI (VMware’s extension cmdlets to PowerShell for managing their products). (more…)
