NSX upgrade precheck warnings with Edge nodes

Products

• VMware NSX

Issue/Introduction

• After running the NSX upgrade pre-check, warnings occur indicating open alarms with the Edge nodes.  However, when looking at the Edge nodes under "System" > "Fabric" > "Nodes" in NSX manager UI, the Edge nodes are showed as "Up" and healthy. 
• Upon checking the error details, you might see similar message as:

Environment

• VMware NSX-T
• VMware NSX

Cause

The NSX upgrade precheck will flag any open alarms for the NSX transport nodes as errors, even when the nodes are working as expected.  This is intended by design.

Resolution

• Identify any open alarms for the transport nodes by going to the NSX manager UI and check under "Alarms". 
  • The relevant open alarms could be associated with objects that such as Load Balancers or VPN's that run within the NSX Edge's, rather than with the Edges themselves. 
• Resolve any open alarms for the NSX transport nodes before proceeding with NSX upgrade. 
• After resolving all open alarms, this precheck warning should not trigger again.
