Resolution

SSH'd into the hosts that are showing "Unknown" and restarted the following: 

• /etc/init.d/nsx-nestdb restart
• /etc/init.d/proxy restart
• /etc/init.d/opsagent

If the above does not resolve the condition, please reboot the esxi hosts.

If the host continues to show in "unknown" state, please open a support request with Broadcom and include the following information:

• Log bundle from affected node.
• NSX Manager log bundle - Management plane only (unless edge is affected).
