Quick Tip - NSX-T 2.1 upgrade gotcha, use NSX Manager IP Address vs Hostname

by // 1 Comment

NSX-T 2.1 was released right before the holiday break and one of the biggest enhancement is support for VMware's upcoming Pivotal Container Service (PKS) which you can read more about here. Right before I took some much needed time off with the family, I had attempted an upgrade of my existing NSX-T 2.0 environment and ran into an issue which turned out to be a known issue but apparently it is no where listed on the NSX-T 2.1 release notes.

I figure I would share the simple workaround as it drove me a bit insane trying to figure out what was going on. After successfully uploading the NSX-T 2.1 upgrade bundle and then starting the upgrade, which starts off by updating the Upgrade Coordinator component and shortly after, I am shown the following error message:

This page is only available on the NSX Manager where Upgrade Coordinator is running. To enable the service, run the command "set service install-upgrade enabled" on the NSX Manager. If the install-upgrade service is already enabled, try disabling it using "clear service install-upgrade enabled" and then enable it again.

Although the error seems to suggest the Upgrade Coordinator service may not be running (it was), even after performing the recommended operations, the error message continue to persists as seen in the screenshot below.


After reaching out to Engineering as I was out of ideas on how to further troubleshoot the issue, it turns out this was actually a known upgrade issue going from 2.0 to 2.1. Instead of connecting to the NSX-T Manager using its Hostname (FQDN), I needed to use the IP Address instead for the upgrade. Once I logged back in using the IP Address, I was no longer seeing the error message and could proceed with my NSX-T upgrade as shown in the screenshot below.

Deploying NSX-T VIBs and/or creating custom NSX-T Image Profile

Similiar to its earlier predecessor, NSX-T also provides complete lifecycle management (LCM) of its underlying NSX components (Controllers, Edges and Managers) including the Fabric Nodes (e.g. ESXi and/or KVM hosts). Additionally, a new Upgrade Coordinator is now part of NSX-T which greatly simplifies the patching and updating of the network virtualization platform. However, for existing vSphere customers who already have a process for distributing VMware VIBs using vSphere Update Manager (VUM) and/or custom Image Profiles, being able to leverage their existing methods is quite important. This is especially true for customers or system integrators who wish to slipstream all necessary VIBs as part of their base ESXi image for initial deployment which may come in the form of an automated installation via Kickstart and/or even manual install using an ISO image.

The good news is that like NSX-V, NSX-T also supports the same set of deployment methods that customers are already familiar with. I had recently looked into this due to a few questions that I and a few other folks had during our NSX-T Bootcamp training a couple of weeks back. I also did not see anything in the existing NSX-T documentation and figure it would be useful to outline the specific steps for each of the installation methods, especially when creating a custom ESXi Image Profile using PowerCLI which requires a particular order.

Note: Auto Deploy is currently not supported with NSX-T.

NSX-T PowerCLI community module

by // Leave a Comment

During the development of my automated NSX-T 2.0 lab deployment script, I had created several PowerCLI functions using the new NSX-T cmdlets and NSX-T APIs to help me test and troubleshoot. I finally got a chance to clean up the code as well as package them all up into an NSXT.psm1 module which hopefully can benefit others. For those of you who are looking for a primer on how to get started with the new NSX-T PowerCLI cmdlets and the NSX-T APIs, check out this awesome post from Romain Decker.

The NSXT module contains the following 8 functions:

  • Get-NSXTComputeManager
  • Get-NSXTController
  • Get-NSXTFabricNode
  • Get-NSXTFirewallRule
  • Get-NSXTIPPool
  • Get-NSXTLogicalSwitch
  • Get-NSXTManager
  • Get-NSXTTransportZone
