Compute Manager constantly showing a "Connection Status" of "Connecting"

Products

• VMware NSX

Issue/Introduction

When viewing the Compute Manager (vCenter) inventory in the NSX Manager UI, the "Connection Status" of a Compute Manager is showing a status of "Connecting" but never fully connecting or failing.

The cm-inventory.log file is not generating or updating on at least one NSX Manager node in the cluster.

Environment

NSX 3.1.1

Cause

The cm-inventory service on at least one NSX manager is not fully running.

Resolution

Check Status of cm-inventory service on all the NSX manager node

Admin: get service cm-inventory

Root: /etc/init.d/cm-inventory status

Restart the cm-inventory service via CLI on all three Manager nodes using the below command and reassess the connectivity to the Compute Manager.

Root User: 
/etc/init.d/cm-inventory restart

Admin User:
restart service cm-inventory

Note: This command should be non-impactful but it is recommended to do so during a maintenance window, especially if multiple Compute Managers are connected in the environment, to reduce the potential risk.
