Yesterday I had an issue with my NSX-T 3.0.1 deployment in my lab. I was not able to resolve the issue, so I had to recover NSX from backup. Luckily I was making backups every day. So, it would not be hard te recover right? Well, think again if you are running NSX-T 3.x and you have deployed your Solution with custom certificates in a prior NSX-T version.(more…)
Creating an LACP LAG on a Ubiquiti UniFi switch for Synology NAS
Currently, I am moving my in-house lab to my garage. I installed a cabinet in the garage, bought a new Ubiquiti 24 ports switch which functions as a layer 2 switch inside of the cabinet.
My Synology is now connected to a LAG interface on my 16 Ports Layer 3 switch. Since I’m planning to move all of my hardware to my cabinet in the garage I also need to move the Synology, connect it to the UniFi switch and create a LAG again.
Replace vRO certificates in a vRA embedded installation
Some time ago I deployed vRealize Automation with vRealize Orchestrator embedded in the appliance in my home lab and I’m not very experienced yet with vRA and vRO. The reason that I deployed it is mainly that I want to get more hands-on experience with vRA and vRO and eventually use the gained knowledge for customers.
vRA was already running for a couple of months, and all the frontend self-signed certificates were already replaced by my Microsoft home lab CA issued certs. When I started using vRO, I noticed that the certificate was not replaced yet and that the appliance was still using the default self-signed one. I started googling how to replace the vRO certificate and found the following official VMware documentation. This article states that you can trust the already installed custom certificates in vRA. I executed every step from the official VMware guideline but was unsuccessful to replace the vRO certificates with the procedure. Fortunately, I was able to replace the certificates with another procedure. (more…)
Ubiquiti devices disconnected
Today I had an unfortunate power outage at my home, therefore my lab was shutdown inadvertently. After powering up my systems again some Ubiquiti devices which were registered with my Unifi Controller had the disconnected status, even though I was able to ping them. After some reboots, and re-adoptions I didn’t get them online. (more…)
Lab Expansion: Like in the old days
Currently i’m running my home lab environment on three physical Intel NUC devices. ESXi 6.5 is installed on each one of the NUCs and they are running a vSAN cluster (two M2 SSD inside each NUC, one for cache and the other for the capacity tier). Each NUC comes with 32 GB memory and a Intel(R) Core(TM) i5-6260U CPU @ 1.80GHz installed as well. Due to the fact that the Intel NUCs are just not flexible enough for me to test certain scenarios I decided to expand my existing lab environment.
