PowerCLI and VVols Part II: Finding VVol UUIDs

One of the great benefits of VVols is that fact that virtual disks are just volumes on your array. So this means if you want to do some data management with your virtual disks, you just need to work directly on the volume that corresponds to it.

The question is what virtual disk corresponds to what volume on what array?

Well some of that question is very array dependent (are you using Pure Storage or something else). But the first steps are always the same. Let’s start there for the good of the order.

PowerCLI and VVols Part I: Assigning a SPBM Policy

There are a variety of ways to assign and set a SPBM Policy to a VM. I recently put out a workflow package for vRO to everything VVols and Pure:

vRealize Orchestrator VVol Workflow Package

I also specifically blogged about assigning a policy to a VM with vRO:

Upgrading ESXi environment with PowerCLI

A new ESXi 6.5 patch came out today:

https://kb.vmware.com/s/article/2151104

And I wanted to upgrade my whole lab environment to it and I haven’t set up auto-deploy or update manager yet (I plan to, making all of this much easier to manage). So I wrote a quick and dirty PowerCLI script that updates to the latest patch and if the host doesn’t have any VMs on it, puts it into maintenance mode and reboots it. I will reboot the other ones as needed.

So short, not really even worth throwing on GitHub, but I might make it cleaner, and smarter at some point and put it there. Continue reading Upgrading ESXi environment with PowerCLI

VMware and FlashArray PowerShell GUI tool v2.7

Quick post. I updated my PowerShell GUI tool I maintain for VMware and FlashArray management and added some new features. This time mainly around protection group management. Download it from my GitHub page here:

Unattended VMFS UNMAP Script

I updated my UNMAP PowerCLI script a month or so ago and improved quite a few things–but I did remove hard-coded variables and replaced it with interactive input. Which is fine for some, but for many it was not.

Note: Move to VMFS-6 in vSphere 6.5 and you don’t have to worry about this UNMAP business anymore 🙂

Essentially, quite a few people want to run it as a scheduled task in Windows, and if it requires input that just isn’t going to work out of the box. So I have created an unattended version of the script. For details read on.

Note: I will continue to update the script (bugs, features, etc.) but will note them on my other blog post about the script here:

Pure Storage FlashArray UNMAP PowerCLI Script for VMware ESXi

I will only update this post if the unattended version changes in a way that makes these instructions wrong. Continue reading Unattended VMFS UNMAP Script

Importing a VVol Snapshot with PowerCLI

This is all very exciting for me, finally able to really start blogging about VVols in earnest. As you may or may not be aware we (Pure Storage) currently have our VVol implementation in beta. So I can finally start digging into some VVol work. Not going to get into implementation details just yet, but instead a quick walkthrough of importing a VVol snapshot with PowerCLI.

First, enjoy a poorly photoshopped Back To the Future reference:

PowerShell GUI VMware and FlashArray Storage Management Tool

Here is my storage manager for the FlashArray and VMware. Based on PowerCLI, but uses a front end GUI. Enjoy!

There are a variety of methods of managing VMware objects (VMFS volumes, VMs, VMDKs and RDMs) and the underlying snapshots to recovery or clone them. But often I get asked if I have a PowerShell (PowerCLI) script to do one or all of them. I have a bunch on my GitHub, but I decided a week or so ago to put something a bit more robust together. At first I was making it a standard interactive script, but it morphed into a GUI, using combo-boxes etc:

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

Pure Storage FlashArray UNMAP PowerCLI Script for VMware ESXi

I’ve noticed I am beginning to have some blog post sprawl as I update my UNMAP script over and over so I will be using this post from now on to record future updates. Please use this post as the final word on what is new with my UNMAP Script.

FlashArray VMware Best Practices PowerCLI Scripts

I wrote a post recently on the updates made to the PowerCLI 6.3 R1 esxcli implementation, so the logical next step was to implement this new behavior into my PowerCLI scripts that use esxcli. I still have a few scripts to update, but my two best practice-related scripts are ready to go. The two scripts are:

  1. Script to check and set best practices. Download here:
  2. Script to just check best practices, and lists issues in a report. Download here.

While I was updating them for esxcli changes, I figured i might as well improve them too, so there are quite a few changes for both. Let’s take a look.
