NSX-T is able to Stage the VIBs onto vLCM, then I go to the Cluster > Updates > trying to run pre-checks and I get this error. I try Remediate and its failing as well.
I opened a few cases with vmware support but it just seems this process is new to everyone and no solution yet.
NTP is all synced and NSXT is registered with Compute Manager using an Administrator level account.
Any ideas? Thanks.
Seems there is a fix on the version you are trying to go 🙂
However, could be something different, what do you see here: /var/log/upgrade-coordinator/upgrade-coordinator.log. That log is inside the NSX Manager.
Thanks for the reply! I did figure it out. For anyone that swings back this way, the solution for me was a bad SSL certificate in one of the vCenter services. So, when it was saying it failed to do the health check, the translation was that NSX Manager was unable to communicate with vCenter and the vLCM in a trusted manner and the connection was being aborted. Updated the thumbprint in NSX and boom, all gravy.
The Fix is to Restart NSX Managers.
There was a session ID/Tokent ID that got created between NSX-T Managers and vlCM when you register NSX-T with vLCM.
Yes, the fix also is listed on the new Upgrade bundle.
Fixed Issue 3028358: vLCM remediation of a host cluster fails because of NSX-T health check issue.
The NSX-T log of the Upgrade Coordinator indicates a null pointer exception, which causes the API call to fail with HTTP 500 Internal server error.
