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

FlashArray Workflow Package for vRealize Orchestrator version 1.3

Quick post. I have released the FlashArray Workflow Package for vRealize Orchestrator version 1.3. Not a huge update but a few changes/new features.

Increasing VMFS capacity with vRealize Orchestrator

I am working on adding some functionality to the FlashArray workflow package for vRealize Orchestrator and one of those features is automating the process to increase the capacity of a VMFS volume. The FlashArray potion of that is pretty straight forward but what of the VMFS portion? Not much on the internet directly about this. Luckily using the vCenter SDK with vRO, this is pretty easy.

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.

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

VAAI XCOPY not being used with Powered-On Windows VM

This is an issue I discovered along with my good friend and former colleague Drew Tonnesen a few years back which has cropped up a few times in recent days. I noticed there wasn’t really any information about it online, so made sense to put a quick post together.

In short, Windows 2012 R2 virtual machine clone or Storage vMotion operations complete much slower when powered-on as compared to when power-off. The common explanation is that VAAI XCOPY does not work when the VM is powered-on. This is not exactly true. Let me explain. Continue reading VAAI XCOPY not being used with Powered-On Windows VM
