CORFU_NONCONFIG and DATASTORE Services are UNKNOWN on post redeploying an NSX Manager

Products

• VMware NSX

Issue/Introduction

• In the NSX_UI under System --> Appliances --> VIEW DETAILS and when reviewing the Service Status for CORFU_NONCONFIG and DATASTORE these are reporting as UNKNOWN 

• After Using the NSX-CLI command to detach NSX Manager for example using the UUID of the node detach node <UUID> ,please note that Detach node command will only detach and remove NSX Manager from the NSX Manager cluster but it will not delete or power off the NSX Manager virtual machine from the vCenter Server inventory.
• NSX manager has been redeployed using the same IP address and by mistake the detached NSX node has been powered on 

Cause

Once the NSX-Manager is detached from the cluster using the NSX-CLI it should be  power off the NSX-T Manager VM and delete the VM from disk. This would aviod the incorrect NSX Manager been powered on . Please note that this work-flow is implemented in the NSX_UI when the node it deleted in the NSX_UI 

Resolution

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

Workaround:

When detaching a node from NSX Node from NSX Cluster it needs powered off and deleted from Disk, This workflow is completed when completing it in the NSX_UI 

System -- > Appliances --> Selecting the required NSX node to delete  --> ACTIONS --> Delete 

If a new NSX node needs to be deployed again you can use the NSX_UI --> System -- > Appliances --> ADD NSX APPLIANCE

If the above workflow fails to resolve the issue , open a support case with Broadcom Support and refer to this KB article.
