Using the Pure1 REST API Part I: PowerShell

In my last post, I spoke about the ins and outs of using the Pure1 REST API–but it was a fairly manual process. Which of course is not how you really want to use a REST API. So the first part of this series will be using it with one of my favorite tools: PowerShell!

I will separate this into five parts:

  1. Creating your certificate
  2. Adding your public key into Pure1
  3. Creating your JWT
  4. Authenticating with Pure1
  5. Making REST calls after authentication

UPDATE!!!! I made this much easier, you can use my module to connect to Pure1 which is on the PowerShell gallery.

You can find more information on it here:

Volume matching via the API in Purity 5.0

Core to most scripting with the FlashArray is figuring out what volume is on what FlashArray. Then you proceed to do what you need with it (snapshot, report metrics, whatever).

Traditionally how this was done, at least from a VMware perspective was via the NAA (network address authority). You take this number, which is how ESXi uniquely addresses a volume and slice it up to find the array serial and the volume serial. By matching the section with a particular array serial, you have identified what array owns it. Then you can make the calls to that array.

Details on how this worked are beyond the scope of this post, but you can see this here:

Using Postman with the FlashArray REST API

Quick post here.

I received a question today on using the FlashArray REST API with Postman, so I figured I would write a quick walkthrough on how to do it.

Protection Group Recovery in PowerShell

Awhile back I wrote about performing an operation introduced in Purity 4.6 called protection group copy, which I really referred to as protection group recovery, which I think is maybe a more apt title.

Anyways, this feature is available in our REST API and our CLI (not yet in our GUI in a direct format) but is not yet built into our PowerShell SDK.  I have seen more than one request for information on how to do this, and it certainly can be done without our official SDK and this is through the good ol’ Invoke-RestMethod cmdlet built into PowerShell. I’ve spoken about using this many times, here and here.

Let’s walk through it specifically with protection group restore.

Force the Invoke-RestMethod PowerShell cmdlet to use TLS 1.2

I wrote about some security changes in the FlashArray operating environment (called Purity) version 4.7 a month or so back. This was concerning the deprecation of SSL and TLS version 1.0, forcing all (management) connections to the FlashArray to use TLS 1.1 or 1.2 (read this here).

Our PowerShell SDK was enhanced so it would use the appropriate security connection type so users of that do not need to worry as long as they upgrade our SDK. But what about the few remaining functions that people might use that the PowerShell SDK doesn’t cover? As there are a few REST calls that are not built into the SDK (yet).  Continue reading Force the Invoke-RestMethod PowerShell cmdlet to use TLS 1.2

Using PowerShell with the VMware Log Insight REST API

I have quite a few PowerShell scripts these days and I run a bunch of them quite often. All of my scripts log information to a file so I can see what happened but I decided I wanted to log them into something that could help me analyze or quickly review the data. Something better than looking at a bunch of text files. One of my favorite products, VMware Log Insight was the first thing I thought of. The ingestion REST API makes the most sense. Took a little time to figure out the best way to do it, but it’s working great now. To the details!

vRealize Automation and the FlashArray

I want to say this is the culmination of my last almost two years of creating vRealize integration for Pure Storage, but that isn’t the right word. It is a milestone, because there is still so much more cool stuff to be done. Especially with vRealize Automation. In many ways it is just the beginning! But I can now demonstrate Pure Storage FlashArray integration with the whole vRealize stack: Log Insight, Operations, Orchestrator and Automation.

Log Insight has a Content Pack. Operations has the Management Pack. Orchestrator has the Workflow Package. Automation also uses that Workflow Package. Let’s talk about how.

vRealize Orchestrator and Invoke a REST Host Workflow

Continuing my recent work on learning vRealize Orchestrator and ran into some funkiness with the “Invoke REST host” workflow, that I wanted to write down so I don’t forget how I fixed/worked around it (which I suppose is the impetus for basically every post I do). Anyways, I am working on a REST-based package for the FlashArray and I was using that workflow and had some trouble. Basically, any REST call I made through it to a REST host seemed to fail.

Understanding vRealize Orchestrator Authentication with the FlashArray REST API

UPDATE: This is a older post, but after working with vRO for longer and learning a lot more about it I decided I needed to re-write this post. Too much of it was not the best way to do things.

One of the projects that I have recently taken up is figuring out how to leverage vRealize Orchestrator to manage and execute operations on the FlashArray. Managing the FlashArray is rather easy of course, most of the work revolved around getting vRO up and running (note in vRO 7.0 all of this is much easier) and learning the product itself and brushing up on my Javascript. I think vRO is a pretty great tool, just takes some time to figure out as not everything in it is quite intuitive, but it seems well ahead of what is was when I last used it a few years back. Once you get the feel of how to leverage it though, you can see how powerful it could be. I’ve just scratched the surface of it and am already excited on what I can put together.

Using the Chrome Advanced REST Client with the FlashArray

A question came up on our community about a Chrome extension called Advanced REST Client and I had never used it before, so I decided to check it out. Install it here. It will add an extension that allows you to make REST calls to, well whatever from your Chrome browser.

***UPDATE My coworker Barkz did an excellent post about this a few months back too, so check it out too***

Of course there are a billion ways to do this (I traditionally have just used Invoke-RestMethod in PowerShell) but this is another one for your tool arsenal . A quick and easy way to pull REST information from the FlashArray without having to learn another tool like PowerShell to do it.
