A new ESXi 6.5 patch came out today:
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
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:

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
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:

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:

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.

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:
- Script to check and set best practices. Download here:
- 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.

One of the changes in VMware vSphere PowerCLI 6.3 R1 was a much needed one: how the arguments are managed with esxcli commands. This was always a bit of a pain, especially for commands that have a lot of arguments. I won’t go into the detail on all of why/what of the changes here, as Alan Renouf already did that quite well here. So if you are unsure of the previous ugliness of esxcli in PowerCLI read that post before reading more here. Otherwise, continue on. I want to talk about some specific examples for storage-related commands that I use and many of our customers use quite commonly.

So in a blog series that I started a few weeks back (still working on finishing it), I wrote about managing snapshots and resignaturing of VMFS volumes. One of the posts was dedicated to why I would choose resignaturing over force mounting almost all of the time.
An obvious question after that post is, well when would I want to force mount? There is a situation where i think it is a decent option. A failover situation where the recovery site is the same site as the production site, in terms of compute/vCenter. The storage is what fails over to another array. This is a situation I see increasingly common as network pipes are getting bigger.

This is part 1 of this 7 part series. Questions around managing VMFS snapshots have been cropping up a lot lately and I realized I didn’t have a lot of specific Pure Storage and VMware resignaturing information out there. Especially around scripting all of this and the various options to do this. So I put a long series out here about how to do all of this. Let’s start with what an unresolved VMFS is and how to mount it.
The series being:
- Mounting an unresolved VMFS
- Why not force mount?
- Why might a VMFS resignature operation fail?
- How to correlate a VMFS and a FlashArray volume
- How to snapshot a VMFS on the FlashArray
- How to mount a VMFS FlashArray snapshot
- Restoring a single VM from a FlashArray snapshot
