Pre-upgrade checks failed for MP: Failed to execute Check for the version sync status of UC on all the MP nodes error observed during NSX Upgrade

Products

• VMware NSX

Issue/Introduction

When attempting to start upgrade for NSX Managers there is a failure with the below error message and the upgrade does not begin.

Pre-upgrade checks failed for MP: Failed to execute Check for the version sync status of UC on all the MP nodes .. Failed to execute method GetStatusSummary. upstream connect error or disconnect/reset before headers. reset reason: connection failure, transport failure reason: delayed connect error: 111

Environment

VMware NSX

Cause

This issue occurs due to service unavailability or network connectivity problems between the manager nodes. There is a built-in pre-check to verify that the UC version is exactly the same on all MP nodes. The process of checking the version fails because the primary node cannot connect to the remote nodes to retrieve their UC version.

Resolution

This is a condition that may occur in a VMware NSX environment.

Workaround

• Wait and retry. If you recently performed actions that involved service restarts, wait for a brief period to ensure all services are fully running and initialized, then retry the upgrade.

• Verify services and connectivity. If the issue persists, check the service states on all manager nodes and verify that there are no network connectivity issues blocking inter-manager communication.

If the issue persists and no connectivity issues are observed then please raise a Broadcom support ticket for assistance. If you are contacting Broadcom support about this issue, please provide the following:

• NSX Manager support bundles.
• Text of any error messages seen in NSX GUI or command lines pertinent to the investigation.
