Getting Started With Packer to Create vSphere Templates – Part 1

Virtual Machines Templates, why? Templates are a great way to achieve consistent, repeatable and fast virtual machine (VM) deployments, be it an on-premise vSphere environment or cloud based environment. Having up to date VM templates for each of the operating systems you use, is key to being able to deploy infrastructure quickly and easily across

Upgrading Site Recovery Manager (SRM) 8.3.1 to 8.4

I recently started looking at prerequisites to a vSphere 7 upgrade, by reviewing any associated upgrades that might be needed. VMware Site Recovery Manager was one product that needed to be upgraded prior to this. I decided I would fire up a quick nested setup in my HomeLab to run through the process before hand

Upgrade vRealize Operations Manager (vROPS) 7.5 to 8.4

Recently I tested a vRealize Operation Manager (vROPS) upgrade from version 7.5 to 8.4 ahead of a vCenter 7.0.2 upgrade and thought I would share the process. Something worth noting with this upgrade. vROPS 7.5 is based on a SUSE Linux OS, 8.4 is Photon OS. Before we install the 8.4 update, make sure you

Updating PowerCLI and Cleaning Up Old Versions

Following the recent PowerCLI 12.3 release, I’m sure many will be rushing to make use of some of the great new additions which you can find information on here. I thought I would quickly show the process of upgrading to the latest version whilst uninstalling any older versions you might still have installed. Partly because

Enabling Native KMS in vSphere 7.0 Update 2

Some time back I wrote about setting up and enabling a HyTrust Key Management setup for vSphere to make use of VM and vSAN encryption. Following the release of vSphere 7.0 Update 2, VMware have introduced native key management capabilities! This is a great feature as you no longer require a potentially expensive separate key

Get, Set and Remove Perennial Reservations Using PowerShell Functions

Having recently had to do some work with RDM perennial reservations I looked into ways to make this less of a manual headache. There are plenty of examples out there for doing this, which I took as a basis to make a PowerShell function. If anything it was a great way to refresh my PowerShell

Administering ESXi Hosts With ESXCLI using PowerCLI

There are times as a vSphere admin, you are going to want to run ESXCLI commands against multiple ESXi Hosts from a central location. This could be for configuration / administration, reporting, patching or a number of other things. Recently I have been testing different values in the /DataMover/MaxHWTransferSize advanced setting. To make life easier,

Deploying vCenter 7.0 via the CLI

Recently I decided it was time to add a second vCenter 7.0 Appliance to my main lab environment after the lab containing my SRM and vSphere Replication installation ceased to exist… I thought I would take the CLI route as its been a while, and thought I’d share! To begin, you need to decide what

Using Tags To Automate The Assigning Of vCenter Object Permissions

Tags are a really useful component in VMware. They can be used for all manor of things, whether it’s for storage policies, backups, identifying a group of objects or in the case of this post, managing permissions. Having a method of easily assigning permissions to singular or multiple objects in vCenter can be a great

Change ESXi Host Access Groups With PowerCLI

IT security, accountability and auditability are critical today. Securing vCenter Server using auditable identities, for instance via an Active Directory identity source, is likely common for most vCenter consumers. This ensures individual access can be used to audit actions back to an admin as well as provide higher security through strong password policies and the

SRM 8.3 Certificate Management

Following on from my last post on vSphere 7.0 certificate Management, I wanted to continue with another certificate related post. This one being Site Recovery Manager (SRM) 8.3. Like vSphere 7.0, this version seems simpler than previous versions I have used. With SRM, it’s the Appliance Certificate replacement that I am going to take you

vSphere 7.0 Certificate Management

vCenter 7.0 brings many new features, one of which is a much smoother certificate management experience. There are now 4 main ‘modes’ for certificate management. These are; Fully Managed Mode, Hybrid Mode, Subordinate CA Mode and finally Full Custom Mode. There is a great article here from Bob Plankers explaining the difference between each. As

DFS NameSpace Issues – Migrating From FSR To DFSR Following AD Upgrade

I recently assisted a friend who had an issue with DFS Namespaces following an Active Directory Upgrade from 2008R2 to 2012R2.  They were faced with not being able to access the NameSpace following the demotion of the last 2008R2 controller and promotion of the final 2012R2 controller. Upon opening the DFS NameSpace management console, the

VM and vSAN Encryption

In this day an age, securing data is a must.  In this post I’d like to show you two options for protecting your data; vSAN Encryption & VM Encryption. To achieve either of these you need to have connected a Key Management Server (or Cluster) to your vCenter server.  Check out my previous post of how to

Deploying and Connecting A Key Management Server to vCenter

Is it secure?   This has to be one of the first things you consider with any technology solution or decision today.  So when I was lucky enough to receive a NFR license from HyTrust for their KeyControl Key Management System I was excited to get this into my lab so I can make use of VMware’s vSAN and VM Encryption.

Configuring ESXi for iSCSI Storage Using PowerCLI

Configuring host VMKernel adapters for iSCSI can be a time consuming process. PowerCLI can take away a lot if not all of the effort. Below is an example of using PowerCLI to create a Standard Virtual Switch (vSS), configure a VMKernel adapter, set the VLAN, enable the software iSCSI adapter (if that’s what you are

Centos Based Certificate Authority For The VMware Lab

A useful thing for a home lab or VMware lab, is a certificate authority. There are Windows based CA’s as well as Linux based and many others. I wanted to take the Linux based route for my home lab to give me some administration time in Linux, being that Windows is my safe place! After
