All vCenters not showing up after adding a new one to an SSO Domain

As I have mentioned before, the company I work for had a disaster event that took place almost a year ago and because of that we have had  some of our infrastructure duct taped together.

Today I am proud to say that I had the opportunity to rip off another piece of that duct tape and actually move our Virtual Infrastructure forward.

You see, Pre-Disaster we had a single vCenter appliance which managed 3 sites. (Yes I know… yuck)

But, because of the disaster we had to move all of our services from the 1 site to the other 2. In the middle of the DR event I had to create 2 VCSA appliances to be able to manage the 2 sites, and due to a lack of sufficient network connectivity at the time, they were just islands. I even set them up a separate SSO Domains.

Fast forward to today, and I have now consolidated these 2 SSO Domains down to 1 and I must say it is pretty slick.

I did however run into a bit of an anomaly, which is the purpose of my post today. You see on the VCSA appliance that was added to the existing SSO domain, I discovered that I could see the first VCSA Appliance in the vSphere Web Client as well as it’s inventory which was awesome!

However on the vSphere Web Client of the Original VCSA Appliance, I can only see the 1 VCSA Appliance.

I consulted Dr. Google but found nothing at first, until I came across this post on the IBM Cloud for VMware Solutions site.

It turns out that you need to restart the vSphere Web Client in order for the new vCenter server to appear.

Just encase the link dies I will post the resolution here:

This is a known VMware 6.5 issue.

To resolve the problem, you must restart the vSphere Web Client:

Using the root account, connect over ssh to the vCenter VM (virtual machine) of the previously ordered instance.
Type shell to enter the bash shell.
Enter service-control –stop vsphere-client to stop the client.
Enter service-control –start vsphere-client to restart the client.
After the vSphere Web Client of the previously ordered instance is restarted, confirm that the vCenter Server system for the newly added secondary instance is visible in the vSphere Web Client.

NOTE: Rebooting the VCSA Appliance will also resolve your issue.

I hope you found this helpful, and if so please let me know and share with your friends.

How to Create a Virtual Machine using VMware Workstation Professional 15

Continuing on from my previous post, I wanted to go through the process of creating a Virtual Machine with VMware Workstation Professional 15. Mostly because the last time I did a how to create a VM post, it was a few years ago and it was vCenter 5.5, and because I will be building off of this for future posts.
So let’s get started.
Launch VMware Workstation Professional 15 Pro and you will be presented with the following screen. 
You will want to click on the Create a New Virtual Machine Button (Circled in Red below)

That will launch the New Virtual Machine Wizard.

From here you will want to select either Typical or Custom for your installation configuration. For the purposes my installation I am going to go with a Custom installation. 

After selecting Custom click Next. You will be presented with the option to choose your Virtual Machine Hardware Compatibility. 

As as you can see from the drop down menu below there are many options to choose from. Each option has different compatibility requirements which also brings different limitations. Also remember that Newer Hardware Versions will not be compatible with older versions of VMware Workstation, so if you have to move between versions please keep that in mind. 

For our purposes I will be Selecting ESXi 6.5, which should allow me to import this VM into an ESXi environment without needing to use VMware Converter. I will probably cover this in a later post. 

After making your selection, click Next to specify the OS for your Virtual Machine. You can either select and Installer disk, and Installer Image File (.iso), or I will install the Operating system later. For the purpose of this post I will be installing from a Image File (.iso). 

Click on browse to be prompted to select your Image file.

Select your installer Image File and click Open to continue. 

Depending on the .ISO you are using as the installer, VMware Workstation will attempt to determine what Operating System (OS) you are trying to install. This will also provide recommended settings based on your OS.

Click Next to continue on to name your Virtual Machines and specify where I want the Virtual Machine files to be located.

Click Next to move on to set Processor Configuration. The Processors are capped at the total number of Virtual CPUs available on your machine. If you try to over provision your processor you will get a Error message. 

Click Next to continue on to set the Memory for the Virtual Machine.

As you can see there is a “Recommended Memory” setting when you get to this screen. This is gathered from the .ISO check a few slides back. Click Next to continue on.

For Network Type you have 4 Options as seen above. The default is to use network address translation. This setting is all dependent on how much access you want to give to your VM. Do you want it to be accessible to or from your network? Perhaps you are setting up a VM to test some dangerous program? All these things you need to consider before clicking Next to continue. 

On this screen you will need to select your I/O Controller. I went with the recommended setting and clicked Next to continue.

 On the next screen you will be presented with options for Virtual Disk Type. Depending on what you will pick will determine compatibility with other Hypervisors in the future and can cause a real headache for someone else down the line if you don’t consider your options. I will cover that in a different post. For my purpose I will be sticking with SCSI which is recommended and is also the default selection.  

Next you will be asked to Select a disk from the following option.

As this is a new Virtual Machine I will be selecting Create a new Virtual Disk and Clicking Next.
You will then be presented with the following screen where you can specify the size of your Virtual Disk, if you want to Thick Provision it, and how you would like the file stored. 

Make you selection and Click Next to Continue. Next you will be able to Name the Virtual Hard disk and Specify what storage it will be installed on. 

 

Click Next to continue. Review your settings and Click Finish to continue.

It’s Official!!!

I just received my digital books for VMware vSphere: Design Workshop [V6.5]! I am looking forward to taking this class next week

Say hello to my little friend…..

So this little baby came in with the Amazon guy today!

As part of my preparation for the VCAP – DCD 6.5 exam that I am taking, I purchased this book which came recommended by the author whose blog I follow and listed on my VCAP 6.5 page.

I must say I have read many IT books in my time in this field that this one is probably my favorite. It is very concise and to the point. The book is broken up into small sections or “recipes ” which are easy to digest and understand. Even the sections that I usually find boring or hard to get through was not as much of a struggle for me this time around. The author also left little nuggets of wisdom which I found helpful and fascinating.

I also loved the message in the beginning of the book from the publisher that said if there was any erroneous information or misspellings that you can email them to let them know so they can correct it in future revisions. This was so refreshing, I cannot tell you how many time I have read a book with misspellings or wrong information and it can really trip you up. You try to get in contact with the author or the publisher and nobody cares. I think more publishing houses should adopt this mentality.

I look forward to doing a full review of this book at a later time (depending on how well I do on the exam)
