Re: Why you should upgrade to vSphere 6.5 / ESXi 6.5

Recently I went to extend a volume on one of my guest systems and received an error requiring me to power off the system before extending the disk.

ErrorHot-extend was invoked with size (5368709120 sectors) >= 2TB. Hot-extend beyond or equal to 2TB is not supported. The disk extend operation failed: msg.disklib.INVAL

Good News – With vSphere 6.5 this is no longer a limitation.

Just one more reason why you should think about upgrading your VMware environment to the latest.

Install Windows Server 2016 Step by Step

There may come a time that you may need to install Windows Server 2016.
Here I will provide a high-level step by step on this installation process.

Requirements:

Windows Server 2016 Installation media (DVD, USB flash, WDS, etc.)
Installation Target (Computer, Server, Virtual Machine)
Keyboard (Mouse is optional)

Video Example of Installation:

Installation Steps:

Power on Installation Target (Computer, Server, Virtual Machine), specify the language, time zone and keyboard or input method then, click Next.

Click Install now on the Windows Setup screen.

Enter your license key or click “I don’t have a product key”.
This option is normally chosen when you have a local KMS host used to activate the Windows Installation

Select the desired Windows Server edition, Click Next.

Accept the license terms by placing a check in the box, then click Next

On the next screen choose “Custom” install. This is for clean installs of the Windows OS

Select the disk, you want to install the widows on, click Next

The installation will copy files and install the base features and updates. When complete the computer will reboot. After your restart, you will be asked to compose a secure password. Once completed you will be able to log into your Windows 2016 Server.

Job well done.

My VMware Certification Experience

I recently received my VCP6-DCV Certification from VMware by Passing the 2V0-621 Proctored Exam with Pearson VUE.

The Journey

For many years I have used VMware products. I distinctly recall getting my hands on VMware Workstation back in 2001, and it was truly an amazing tool. I could emulate Windows 3.1 and Windows 95, QNX, and even a few BSD environments, which I used to learn and troubleshoot issues.

Over the years I continued to use VMware line of products from: Workstation, ESX, GSX, and lastly the introduction of VirtualCenter.

Fast forward to now: The latest products have changed the landscape of running the data center, desktop provisioning, and the rapid deployment of test/development systems.

It was a no-brainer that I should obtain a certificate, but I never felt the need to. This changed when I was made a vExpert in 2017 this year, and that initiated my drive to do more with my knowledge and experience with the product. I now wanted to “prove” to myself, and perhaps others that I had what it takes to pass the exam and have an official recognition backing my previous and current experience levels.

VCP6-DCV Prerequisite

Obtaining the VCP6-DCV Certification requires a set of prerequisites. You need to meet all 3 requirements:

  • Attend an authorized training course
  • Pass the vSphere Foundations exam (2V0-620)
  • Pass the VCP6-DCV exam (2V0-621)

Training

The most difficult part of my path to being a vCP was finding a reputable company to train with in addition to scheduling the time to attend training. The following may sound like a plug and do I assure you that I am not being compensated for writing about them.

I choose to train with a company by the name of StormWind as they offer exceptional VMware Certified professional training which is not only budget friendly, but doesn’t require travel as training is instructor lead; Live in real time and can be done from the comfort of your home or office.

The course I enrolled in was: VMware vSphere: Install, Configure, Manage [V6], with instructor: Vince Rightley.

This was a very engaging class which allowed for attendees to not only be instructed but to participate in supplemental discussions which I personally found to be beneficial. Labs were particularly useful as they allowed for students to get hands on.

Study

vSphere Foundations exam (2V0-620)

After completion of my course I was now qualified to take the vSphere Foundations exam (2V0-620). Admittedly I rushed in to take this exam and FAILD my first attempt.

This was an eye opener that I was not fully prepared to take the test. What I discovered was that many of the resources can be found on VMware’s My Learn site. I would highly recommend following their guidance.

VCP6-DCV exam (2V0-621)

After successful passing the vSphere Foundations exam (2V0-620) it was time to start preparing myself for the VCP6-DCV exam (2V0-621)

VCP6-DCV exam Preparation

I have a few suggestions to make regarding preparation for the VCP6-DCV exam which I believe was beneficial to my success in passing.

Study the materials you obtained in your training course. Continue to leverage the study notes you made for yourself from the Foundations exam (2V0-620). Yes! You should have been keeping notes.

Seek out resources from VMware’s My Learn site. They are beneficial to your success.

Search ‘Google’ for VCP-DCV Study Guides. You will find many results many of great value

Practice Labs

I highly recommend that you gain access to a lab such as VMware’s Hands-On Labs (HOL) to get hands on to all the subject areas covered under the VCP6-DCA as you will need them. I built my own lab so I could have the full experience of building from scratch, to give me a full understanding of the environment.

Test many scenarios including areas of troubleshooting things which are broken (I had to break them, so I could fix).

Familiarizing yourself with acronyms and terms is also very helpful. Example: http://jermsmit.com/vmware-vcenter-terms-acronyms-glossary-tag-your-it/

Find yourself a practice test, and take it once a week to get yourself in accustom to taking tests; In my case it’s been a long time, and practice pays off.

[SOLVED] Unable to migrate VM’s to other host

I had encountered the following issue when attempting to migrate a live VM to another host w/in my lab cluster.
The error received was: 

Currently connected network interface” ‘Network adapter 1’ cannot use network ‘VM Network’, because “the destination network on the destination host is configured for different offload or security policies than the source network on the source host”.

I was able to fix this by checking the configuration of the virtual switch (vSwitch0) on the ESXi host I was moving the virtual machine guest to.

  1. I click on each host went to the configure
  2. Under the Networking subsection located the virtual switch
  3. Selected edit on that virtual switch.
  4. Reviewed the settings in the Security tab and the Traffic Shaping tab between the hosts.

In my case the issue was with the Security tab.  The destination host did not match the source.
Just another reasons to use host profiles between systems so that settings all match.
