VMFS UNMAP switches block count

A recent question I got about my UNMAP PowerCLI script was it says it was using a certain block count but when I looked at the log it was using 200. Why?

Well I blogged before about why a given UNMAP process might revert to the default block count of 200 here. Essentially, if you indicate a block count larger than 1% of the free space of the VMFS ESXi will revert it to 200. Or if the VMFS is more than 75% full it will always override the block count back down to 200. Continue reading VMFS UNMAP switches block count

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

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.
