REST API changes in Zerto Virtual Replication 5.0 U3

Since my first post back in 2014, many of the example scripts that I’ve shared integrate with Zerto using their bolt-on REST APIs. After 4 years of stability, in 5.0 U3, Zerto changed the requirements of the authorization header to require the content type in addition to the session token as a “security” feature.

Unfortunately, this means that any Zerto script you have downloaded from my blog, customized, or written, needs to be edited to continue working after the upgrade. Without any modification, your REST API calls to Zerto won’t even give you an error, they will just return null. Pretty annoying huh? I’ll be honest in that I was completely livid when I found out. To me, this looks like a pointless change to fix a problem that didn’t exist while creating a heap more by how it is was implemented and communicated.

On top of this, the Zerto API documentation leaves a lot to be desired as it hasn’t even been updated (as of 06/25/17) to reflect the new requirements! But that’s why I’m here to help. So how do you go about fixing your Zerto scripts?

Automatically detecting Ransomware infections with PowerShell

Back in July 2016, I posted a script which used PowerShell to send an email alert upon detecting a Ransomware infection by continuously comparing a purposefully vulnerable word doc for changes, deletion etc. The script also integrated into Zerto to insert a checkpoint, but what if you don’t have Zerto and you just want to get the email alerts? I’m presenting at Foxwoods Casino with a Rubrik partner this afternoon on Ransomware (the irony of the venue and subject not lost on me) and so I wanted to post a non-vendor integrated example as a free giveaway for everyone attending the presentation and reading the blog. This post will give you just that.

Bandwidth throttling your home lab and Rubrik replication/archiving

Having your own home lab is one of the best tools you can have to progress your knowledge and career in IT. But, having lots of VMs and hardware can equal a decent load on your home internet connection. This gets even worse when you start using replication and archiving technologies. So how can you stop your home lab from saturating your internet connection, interrupting the family movie night (yes this happened to me), and the plethora of streaming services used in a modern household?

Upgrading your home lab to 10GbE on the cheap!

Since building my hyperconverged home lab in Jan 2015 and finally sharing it on my blog Jan 2017 it has quickly become the most popular blog post by quite a margin. But one thing has always bothered me about the lab, with 1 SSD per ESXi host, and that’s the connectivity. Stuck in the slow lane at 1GbE it was always the limiting factor when configuring replication between hosts with Zerto and performing an initial sync. This was made even worse when I wanted to plug in a Rubrik r344 appliance (Supermicro 4 node server with 4 x 10GbE cards) because no matter how fast Rubrik can ingest the backup and live mount it back over NFS, 1GbE is as fast as it will go. Demonstrating live mounts over 1GbE certainly works, but it’s not the same wow factor as it is with 10GbE.

Something had to give. Do I build a new lab using motherboards with built-in 10GBase-T NICs? Read more of this post

Automatically Updating To PowerCLI 6.5.1

I’m blogging live from the Boston Summer VMUG Usercon 2017 where I’m sharing my top 10 PowerShell tips and tricks. A big topic at the show, for anyone interested in PowerShell and PowerCLI, is the change with PowerCLI 6.5.1 in how you install, update and load it. This is pretty important because all your scripts are going to need updating! Otherwise, they will potentially stop working if you are about to or have already upgraded to vSphere 6.5.x. There’s no reason that I’m aware of that you can’t upgrade in advance and still interact with vSphere 6.0 etc. So now is as good as time as any to start planning your upgrade.

Before PowerCLI 6.5.1 you would’ve used this at the start of each script:

Add-PSSnapin VMware.VimAutomation.Core

See you next week at ZertoCON 2017!

Hi all,

Just a quick Friday update to say that I’ll be at ZertoCON next week as a blogger to catch up on all the latest things Zerto, attend some interesting sessions I have penciled in, and to catch the cool keynote from General Michael Hayden! And of course, there ain’t no party like a Zerto party! If you see me walking around feel free to grab me to talk about any scripts you have ideas for, as I’m always on the hunt for requests.

Scripting a Rubrik Recovery Plan using REST APIs & PowerShell

Following hot on the heels of my first post on an “Introduction to Rubrik REST APIs using PowerShell & Swagger” I’d now like to show you how to easily automate the recovery and boot ordering of VMs as a Recovery Plan.

In the Rubrik HTML5 interface, you can easily recover any VM in just a few clicks with the VMs running on a whopping 30,000 IOPS per brik (Rubrik appliance) giving you a sub 1 minute RTO. However, at scale, clicking on each VM to recover can become tedious, hard to manage and it will always require human interaction. This is where using PowerShell to interact with REST APIs is going to make your life easier by automating the entire process for anything from 1 to 10,000+ VMs. Use cases include: Read more of this post

Introduction to Rubrik REST APIs using PowerShell & Swagger

One thing I’ve always been passionate about is writing scripts that are easy to read and consume. By showing you how to directly interact with REST APIs this enables you to do anything, and not be limited to the PowerShell functions provided by the vendor.

When it comes to working with REST APIs and PowerShell this starts to pay dividends when you want to take all the knowledge you’ve learned from working with 1 platform then use the same skills to connect and leverage another.

My first example of porting skills between platforms follows my recent journey of switching from working for Zerto to Rubrik. In this post I will give you all the information needed to connect and leverage Rubrik REST APIs using PowerShell.

Automated bulk IP address reconfiguration with Zerto Virtual Replication

If you tried to use this example before 04/25/17 there was a typo in the export script which left 2 key fields blank subsequently causing an error on import. I’ve now fixed the issue so now is as good a time as any to give this cool script a run in your Zerto environment for bulk IP configuration.

Logging Zerto Sync States Using REST APIs & PowerShell

A few days ago a Zerto prospect reached out to me on LinkedIn with an interesting script request and there is nothing like a good challenge to get me motivated to pull out PowerShell ISE! With over 1000 VMs to protect their key requirement was to log the start and end time of initial syncs. While the ZVR GUI shows when a VPG was created, it doesn’t show when the initial sync finishes:

CreateVPGEvent
This is certainly an annoying omission and the lack of specific data points isn’t limited to just Zerto; how many other solutions do you use in your environment where you want to know/see something that just isn’t there for seemingly no logical reason? Of course, you could contact your vendor account manager, raise a feature request, wait 3-6 months and cross your fingers that it was even considered let alone in the product. Or you can use the REST APIs to get the data yourself, today, in minutes!
