For the past two days, I’ve been troubleshooting a frustrating issue with my NSX v4.2 cluster. Both nodes refused to start, showing only error code 101 in the browser with no service details (unknown state). Connectivity between nodes was inconsistent, and the Corfu service failed, making troubleshooting even more challenging. What followed was a deep [...]
I don't work with HCX(abbreviation for Hybrid Cloud Extension) for some time, installing the infrastructure at least. Recently I only used it in some VMs and Apps migrations. So it was time to build some HCX infrastructure lab, and in this How to install-pairing HCX Manager and Connector, I will explain how to do this. [...]
When I deploy the latest versions of HCX Manager 4.4.0-build 20427536 and HCX Connector 4.4.2-build-20502808, for some reason, DNS is not set on the deploy of the OVA, and HCX Manager and HCX Connector DNS are not working after deploying. When I try to connect the HCX to vCenter (as the first option), I always [...]
This quick tip about NSX Host Transport Nodes Install Failed, when you get Install Failed, I will explain a simple fix that fixes this problem in most cases.

In this blog post about vCloud Director v10.3 vs NSX-T error Certificate is already trusted, I talk about an issue that is new when you install a new vCloud Director v10.3, or you upgrade your existing vCD to v10.3. In a new vCD install, when you try to add your NSX-T (or V), you will [...]
In this vCloud Director Migrations: Linux vCD external SQL DB to vCD Appliance – Part 2, I will migrate a Linux vCloud Director with an external SQL Server DB into a new vCloud Director Appliance with embedded Postgres DB. Before I start, honestly, I would like that VMware could write documentation that easy to read [...]
Upgrade to vSphere 7 NSX-T Host Transport Nodes is another blog post about upgrading your environment to vSphere 7. When we upgrade our vCenter and vSphere and using NSX-T, we also need to upgrade our NSX-T Host Transport Nodes vib agents in the ESXi hosts. After we upgrade our vCenter and vSphere to v7, we [...]
Today, when upgrading one of our NSX-T, I encounter an error. I saw it for the first time when NSX-T did a pre-check on the ESXi hosts to the new version I got the error "Disk space requirements not met. Please ensure 180MB free space is available in tmp partition to proceed with upgrade". NSX-T [...]
