Issue/Introduction
Symptoms:
- Upgrade precheck shows status as RED due to EMM dry run check failure.
- If upgrade is triggered, it fails at Host cluster upgrade as Hosts cannot enter MM.
Environment
VMware Cloud Foundation 3.9.x
Cause
- This is due to a limitation on NSX-T 2.5.0.0: Edge nodes are virtual.
- The hosts that have edges cannot enter MM without edge appliances being powered off
Resolution
- Start NSX-T upgrade from SDDC Manager.
- Wait for upgrade to complete on UC and Edge cluster.
- Turn off edge appliances from VC when Edge cluster upgrade passes post validate in LCM.
- Wait for Host clusters to be upgraded.
- Turn on edges after Host cluster upgrade passes post validate in LCM.
- Let upgrade proceed with NSX Manager cluster upgrade
