vRealize Orchestrator, TLS 1.2 and Certificate Importing

As I have blogged about before, TLS 1.0 and SSL v3 were deprecated in Purity 4.7, requiring all connections to use either TLS 1.1 or TLS 1.2. This affected a variety of integrations, some we updated, some you just had to alter their behavior. A few VMware products do not/did not use TLS 1.1/1.2 by default, so they either need to altered or upgraded. This almost invariably boiled down to the JDK version that was in use. vRealize Orchestrator is no exception.

Running UNMAP with vRealize Orchestrator

Let me start out with saying I’m embarrassed I have only been using vRO for 8 months or so. It is AWESOME.

The FlashArray Workflow Package for vRealize Orchestrator has been updated to include two new objects:

  1. Auto-expand datastore policy template
  2. Workflow to run UNMAP on a datastore

The creation of the first part is explained in this post. But if you are using the FlashArray it is all built into the package, so you have to do very little work. I’ll explain in a bit.

The UNMAP workflow is generic–it can be used with any VMFS datastore that supports UNMAP. So it is included in the workflow package and it is also standalone for those of you who don’t have a FlashArray. You can get the standalone here:

Automatic VMFS expansion with vCenter SNMP and vRealize Orchestrator

Virtual disk oversubscription is becoming increasingly common and so is allowing people to provision their own VMs. So increasing a datastore capacity is also an increasingly common operation. Because of the performance of flash, merged with ESXi features like VAAI ATS. Expanding a VMFS is easy. Expanding a storage volume these days is easy. But you still have to actually do it. What if I want to automate the process to respond to datastore capacity threshold limits? There are a variety of ways to achieve this. Let’s look at it via vCenter SNMP alerts and vRealize Orchestrator workflows. Continue reading “Automatic VMFS expansion with vCenter SNMP and vRealize Orchestrator”

Deeper detail on using parameters with the FlashArray Python toolkit

Last week I posted about getting started with the Python toolkit, now I wanted to go a little deeper today on using the toolkit beyond connecting/creating a volume. A question I have seen more than once is:

“okay, I understand connecting and getting basic information, but what if I want to pull statistics or more advanced information from the array besides what the default commands? The API glossary for the toolkit doesn’t say explicitly how I can get the information I want”

In short, just because the Python glossary doesn’t explicitly say how to do something or even if you can, it does not mean you can’t. It really depends on what the REST API can do.

Let me explain.

Pure Storage Python Toolkit Intro with Windows

Most of my scripting work here at Pure Storage has mostly been via PowerShell or at times Javascript (for like vRO). But I think it is time to get back into Python especially because of the VMware support for it now.

Pure Storage has an automation toolkit that helps get you started managing the FlashArray so you don’t have to deal with the direct REST work in your Python scripts. You can find information about that here:

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.

FlashArray Host Group Creation PowerShell Script for VMware Clusters

New script to automatically create hosts groups on FlashArrays based on VMware ESXi clusters. This is a script I’ve had out for awhile but only recently revisited and realized it was way out of date and frankly, not very good. So I trashed most of it and re-wrote it. You can find it here:

https://github.com/codyhosterman/powercli/blob/master/createhostgroups.ps1

It is pretty self-explanatory I suppose, but it’s good to review the finer points before you run it. Continue reading “FlashArray Host Group Creation PowerShell Script for VMware Clusters”

SRM Cannot Identify Replicated Datastores on iSCSI Devices

So we ran into a customer issue recently with VMware Site Recovery Manager that I have not seen before and have not found any on-point articles on, so I thought I’d share this one. Was an insidious one too, when troubleshooting this one I could not find the issue, eventually one of our rockstar escalation engineers at Pure (Jacob Hopkinson) figured it out after going through SRM debug logs line by line. Comes down to case sensitivity in iSCSI IQNs. I’ll explain…

Pure Storage vRealize Orchestrator Workflow Package v1.2

I just released the 1.2 version of the Pure Storage FlashArray Workflow Package for vRealize Orchestrator. Like always, you can get this from GitHub:

https://github.com/codyhosterman/orchestrator/

If you haven’t looked at our vRO workflow package, check out my original post here:

FlashArray Workflow Package for vRealize Orchestrator

While this isn’t a huge release in terms of new features, I think it is an important one because it adds (among others) one particularly important workflow. Translating a VMFS datastore object into a FlashArray volume name. Let’s take a look.
