FTF 013: Update NSX-T module on ESXi hosts

By | January 2, 2021

Last week I needed to do an update of NSX-T 3.0 to 3.0.2. The update process is simple and straightforward but I faced a small issue. When I wanted to do the update of ESXi hosts I received the following error on only hosts with vSphere on usb/sd card installed.

Install of offline bundle failed on host... No space left on device vibs

Errur during updating NSX-T bundle on host

There is a quick workaround to install an update separately using VMware Update Manager:

  1. Download an NSX bundle (NSX Kernel Module for VMware ESXi) directly from VMware page.
  2. Add to VMware Update Manager and create a new baseline.
  3. Apply the baseline to hosts.
  4. Remediate (no restart required).
NSX Kernel Modules for VMware ESXi available on VMware page

After performing above steps, NSX-T upgrade coordination detects new version of vib and move the process to the next stage - upgrading NSX Management Plane (NSX Managers).
