Deleted NSX-T Manager from VCenter by mistake, removed node is still showing in NSX UI

Products

• VMware NSX

Issue/Introduction

One of the 3 NSX-T managers was deleted by mistake , and it's still showing in the NSX UI.  There is no option to remove it in NSX.

 

 

Environment

VMware NSX

Cause

NSX Manager that was first added and that was used to deploy the other two NSX-T Manager appliance Nodes can NOT be removed from the NSX UI directly. 

Resolution

SSH into one of the two remaining NSX manager nodes by admin :

 

• Retrieve the UUID of the failed NSX Manager node.

Run the command to view the details of the cluster members.

     get cluster status

The status of the failed node is Down.

• Record the UUID of the failed NSX Manager node.

Run the command to detach the failed node from the cluster

     detach node faild_node_uuid

The detach process might take some time.

• When the detaching process finishes, run the command to view the cluster status.

     get cluster status

The status of all cluster nodes is Up.

 

After that,  a new NSX manager node can be redeployed in the NSX UI.
