Tanzu Kubernetes Grid 2.1 – deployment guide

Tanzu Kubernetes Grid 2.1 – deployment guide

As the documentation is still pretty dry and there is not so much information about that on the internet I’ve decided to post a series of articles describing the Tanzu Kubernetes Grid deployment based on the latest and greatest version 2.1. It’s intended to be a step by step guide that will walk you through the entire process from the begining till the end. Starting from the vSphere, NSX and ALB infrastructure preparation up to a deployment of a sample…

vRSLCM deployment is not available

vRSLCM deployment is not available

During one of the recent VCF 3.9.1 deployments I’ve found interesting challenge while trying to deploy vRealize Suite components. Initially integrated with MyVMware and downloaded a vRealize Suite Lifecycle Manager version 2.1 (the only one avaialble to download). Without paying much attention to the Build Number, which was part of the problem. Even though my vRSLCM was downloaded and properly listed in download history in vRealize Suite tab I was still getting an information that my vRSLCM is not available…

Cloud builder 4.2 – 502 bad gateway

Cloud builder 4.2 – 502 bad gateway

Cloud Builder in VCF 4.2 has enhanced password requirements. Thus if you deploy the appliance with a password which doesn’t match those requirements it’s going to be deployed with an error, making it unusable. While trying to access the GUI you will get “502 Bad Gateway” which is not so meaningful. Trying to access SSH will fail as well. However, accessing the direct console gives a clear information about the problem. Based on that there is nothing left than redeploying…

VCDX BoM

VCDX BoM

As part of my VCDX preparation I’ve read lots of books, blogs and other documents to expand the knowledge and fill the gaps. That was partially one of the most valuable parts of the journey where I learned a lot. Without that I wouldn’t probably even read half of those great books. I can’t say this is something that every candidate must read, but I decided to share this list as a VCDX BoM as I found it valuable for…

A wrap-up of my own VCDX Jurney #291

A wrap-up of my own VCDX Jurney #291

This is a post I was about to write already 2 months ago as a summary of 2020 as it’s imporant to wrap-up a long time I spent preparing for VCDX and also say Thank You. However, due to other tasks, engagements, etc. I just managed to complete it right now! So first things first – finally, after a very long and extremely informative journey at 15 Dec 2020, I finally received probably the best e-mail ever. Hi Pawel, Congratulations! You passed!…

vCloud Director Network considerations

vCloud Director Network considerations

One of the most tricky parts of vCD – networks. It took my some time to to digest how those network relations between different types of network in vCD works. Just to remind we distinguish: External Networks VDC Organization Networks vApp Networks Moreover for both VDC Orgzanization and vApp networks we distinguish folowing types: Directly connected to upper layer network Routed network Isolated Network To complicate even further vApp directly connected network can be fenced 🙂 All networks apart from…

NVIDIA P40 – unable to power on a VM

NVIDIA P40 – unable to power on a VM

During recent Horizon deployment with GPUs for a Customer I’ve encounter an issue related to ECC on NVIDIA P40 GPU card. By the way as per documentation it applies to all cards with Pascal architecture. In NVIDIA documentation you can find an information that apart from installing NVIDIA’s VIB you need to disable ECC. Which is clear for me. However, using nvidia-smi command after installing that VIB the status looks as follows: ECC status is listed as N/A, which I…

NSX-V VTEP, MAC, ARP Tables content mapping

NSX-V VTEP, MAC, ARP Tables content mapping

It took me a while to figure out what information I see while displaying VTEP, MAC and ARP table on Controller Cluster in NSX. In documentation you can find what information are included in those tables but it might not be seemingly obvious which field contains what kind of data that’s why I decided to make a short reference for myself but maybe it will help also someone else. To understand those tables I started with Central CLI to display…
