Replace a Failed Cluster Server

Data Server Node Replacement

One symptom of a failed 

Data Server Node

 is the appearance of offline nodes in the UNUM 

System Health

dashboard as shown in the example below. 

In the example, UNUM displays single ESXi instance with 4 data nodes, all offline.

UNUM System Health Dashboard - Cluster

In the event of a 

Cluster Server

 failure and you have received a replacement

 Server

 from Arista Networks

please use the following instructions to rebuild the

 Cluster

.

Note: 

The replacement 

Server

 you receive has 

VMware ESXi

 installed. You need to add the Server to the

Cluster using the 

cluster_menu.sh 

configuration script.
