Description

Currently in Netscaler Cluster deployments the option for backup and restore is not available via the GUI.
In order to perform this action a manual backup would need to be taken from the cluster nodes.

Instructions

Restoring Cluster Nodes or Adding Replacement Node in Cluster Deployment: 
 
Replace Node-A with Node-B (Node-B is same platform as Node-A with same interface conventions)
  1. Save Node-A config via cli cmd “save ns config” and config gets saved in path “/nsconfig/ns.conf“.
  2. Copy Node-A ns.conf to same directory (i.e. /nsconfig/ns.conf) to Node-B. Make sure license is correct on Node-B.
  3. Plug out Node-A network cables and plug in to Node-B. Then Reboot Node-B.
In the case were the entire cluster is to be restored, this can be done using the same steps above, however this would require the cluster to be rebuilt.   

Note:
  •          All other files to be copied from Node-A to Node-B. Refer to this link.
 
Limitations:
  •          If CLA (Cluster Link Aggregation) MAC is generated from the Faulty Node, above procedure will not work at the current time.​
  •          Currently if restoring the entire cluster the cluster will need to be broken and rebuilt from the restored configuration repeating the above steps for each node as they are added back into the cluster.
