Since few months i’m working with VMware vSAN in my own vSphere homelab. And i tell you, i really like vSAN! If you’re looking for an easy, affordable, very well performing and scalable storage solution, there you go. VMware vSAN is ready to take all your workloads. It doesn’t matter if it’s just your nested lab environment, or something more serious like a Virtual Desktop Infrastructure (VDI), big data or business critical applications like SQL databases and Microsoft Exchange servers.
How does vSAN work?
VMware vSAN takes the local disks of an ESXi hosts and puts them in a storage pool, a so called disk group. Put all disk groups of your ESXi hosts together in a cluster and you’ve got a vSAN datastore. It’s that easy. And it’s also easy to make changes to those disk pools. Add disks, remove disks, or change the complete layout of a disk pool.
Vor einiger Zeit wurde ich von Veeam angefragt ob ich ein Live Webinar durchführen möchte. Nun, ich musste da nicht lange überlegen und habe zugesagt. Die Ideen sprudelten nur so aus mir raus. Naja, fast. Um ehrlich zu sein hatte ich plötzlich eine ziemliche Blockade und meine Musse hat sich spontan in den Kurzurlaub verabschiedet…
Es gibt hunderte Themen über die ich gerne sprechen würde. Seien das grössere technische Dinge oder doch eher die kleinen Tipps und Tricks die einem Admin das Leben etwas eifacher machen. Doch vieles wurde bereits in deutsch- oder englischsprachigen Webinars abgedeckt. Und ich wollte auch nicht einfach etwas aufwärmen sondern was neues bringen. Mein aktuelles Thema ist den meisten von euch sicher nicht neu. Jedoch wurde bis jetzt noch nicht im Rahmen eines Live Webinars darüber gesprochen.
Webinar mit dem VMware vExpert: Alles über das Thema VMware vSAN
Über dieses Thema werde ich am Live Webinar sprechen. Das Webinar dauert rund eine Stunde. Stefano Heisig, Senior System Engineer bei Veeam, euch zeigen wie Veeam mit vSAN umgeht und wie man VMs sichern kann. Veeam ist neuerding offiziell für VMware vSAN zertifiziert! Mein Teil wird viele Punkte rund um VMware vSAN abdecken. Und natürlich bleibt auch noch genügend Zeit für Fragen.
This event is a fixed point in the tech agenda every year. VMworld 2017 is at the door. This event is one of the biggest tech events and a must-attend if you’d like to know more news about virtualization, hardware and software.
At VMworld you can see so many different hardware and software vendors, all related to VMware, see their solutions and get more insights about them. But it’s not only limited to just see stuff. There are various breakout sessions with interesting topics, keynote sessions with announcements. You can attend the Virtual Hands-on Labs onsite to try VMware products or do challanges. If you’re a blogger then you’re invited to hang around in the blogger area to meet other bloggers and write your stories. There are also other places to hangout, take a breake and talk with people. That’s also a reason to attend this event. Meeting people and talking to them. When i attended that event 2016 in Barcelona i met many people that became good friends.

Today we had our Swiss German VMUG kickoff meeting. The committee members were hosted at VMware Switzerland HQ in Zurich. Many thanks to you guys! It’s always a pleasure to be there!
But we weren’t just there to drink coffee and have a nice afternoon. We did some serious work. We discussed many different topics, ranging from our community goals over events to the next steps to keep the ball rolling. The main target we had today was to have a roadmap and an agenda for our very first event. And we’ve got it! So we can now move on with the next steps of planning our very first event. We will target a date somewhere in June this year at a location with hopefully enough space to host a good amount of people. Don’t forget about catering, and of course interesting topics and great speakers!
Let’s talk about history
The Swiss German VMUG was not very active the last few months and years. When i registered at vmug.com to search for a local user group i found out that there is a VMUG in my region, but it’s not very active, no events nor discussions were there. Last year at VMworld Barcelona i had some good chats with people, VMUG leaders and co-leaders about many VMUG (and for sure VMware) related things. They all encouraged me to become a VMUG leader.
I had many nights with less sleep, thinking about this. How would it be to be a leader? What areas of responsibility are there coming ùp to me? How will people react to this? So i contacted the VMUG HQ and asked how to become a leader. This was not a short-term thing. It took some weeks, having some phone calls, writing mails, doing trainings. And now we brought back new life to our local VMware user group!
Swiss German VMUG on social media
To make sure you don’t miss any bits and bytes we invite you to register on our Swiss German VMUG community site if you’re interested to become a member of our user group (and if you’re located in the German speaking part of Switzerland, which would make sense). We’re also present on Twitter and Facebook! We thank you for a follow, and don’t hesitate to spread the word 😉
Today i ran into the problem that i wasn’t able to connect to my vCenter via VMware Workstation. If you’re working in your homelab it’s probably helpful sometimes to have access to a VM console without to connect to an ESXi host, a vCenter Web Client or even via RDP to some management client. You can easily connect to your vCenter with VMware Workstation. I wrote a short article about how to save the login credentials in VMware Workstation.
The error message i’ve had was:
“Unable to connect to the MKS: Login (username / password) incorrect”
I’m pretty sure that this wasn’t the case. I’ve tried it with the @vsphere.local admin and also with my domain administrator. But no success.
When i searched for a solution i’ve found many hints and tips. Let me show you what i’ve found and what was my solution at the end.
Check the ESXi firewall
Next step is to make sure that the ESXi firewall isn’t blocking communication. Make sure the following incoming ports are open: 443, 902, 903
I checked that, all ok. But i still got this error message. The only port i didn’t see on the firewall port list was 903. And i wasn’t able to open this port. But i knew that this wasn’t the issue when i connected my vCenter to my VMware Workstation the last time.
Edit a config file on your ESXi host
Well, i’m not sure if that’s the way to go. Thinking about possible updates etc. some configuration files might get overwritten. But i checked it anyway. It’s in my lab and when something goes wrong or does not work, i can fix it and learn something.
You can use Putty / SSH and vi to edit this file, or go comfortable with WinSCP. Connect to your ESXi host and locate the config file at /etc/vmware/config.
Add the line vmauthd.server.alwaysProxy = “TRUE”
I’m also not sure if a restart is necessary, i did a restart, but it didn’t work either.
Use another port for authentication
You can try to edit the config.ini file in VMware Workstation, located at “C:\ProgramData\VMware\VMware Workstation\config.ini“.
Change the line authd.client.port = “903” to authd.client.port = “902”. After that restart the “VMware Authorization Service” and you should be fine.
That did the trick on my system, i was able to connect to my VMs through VMware Workstation.
Hint: if you’re working with Notepad++ (highly recommended!) then you’re able to save the file after granting administrative access (you see what i mean when you try to save the file). If you’re working with another text editor, you should start this text editor as administrator (just right click => run as administrator). Otherwise you probably won’t be able to save the changes.
