Unable to set up HA in GUI after upgrading to 14.1
Article ID: CTX575058

Description
After upgrading to 14.1 4.42, when trying to add HA node from GUI, the following error will be thrown even RPC password is correct.
Changing RPC password from GUI will not help to resolve this issue.
Resolution
* Please test and verify the change before implementation.
1) In ADC #1 's CLI, add the opposite node ADC#2, just ignore the warning(node ID 0 is for the local ADC, ID 1 is for the remote ADC).
> add HA node 1 <ADC#2 IP>
Warning: One or more RPC nodes are configured with default passwords. For enhanced security, you must change the default RPC node password.
Done
On ADC#1, the ADC#2 's status shows as unknown at this time.
On ADC#2, the ADC#1 can not be seen at this time.
2) In ADC #2 's CLI, add the opposite node ADC#1, the same warning displays, ignore it.
> add HA node 1 <ADC#1 IP>
Warning: One or more RPC nodes are configured with default passwords. For enhanced security, you must change the default RPC node password.
Done
The opposite node's status displays as UP, and sysnchronization state becomes success.
3) (Notes) Don't try to change RPC password before set up HA.
If you change the self-node's RPC password before adding opposite node in CLI as below,
> set ns rpcnode <ADC#1/ADC#2> -password ****
Done
> add HA node 1 <ADC#2/ADC#1>
Warning: One or more RPC nodes are configured with default passwords. For enhanced security, you must change the default RPC node password.
Done
The follwing error will display:
For a solution, reset RPC password on self-node both on the two nodes from GUI, the synchronization state will become success.

Problem Cause
After upgrading to 14.1, "RPC Node Password" is a required parameter in GUI, but there is not a related parameter in CLI command "add HA node". Adding opposite node separatedly on the two nodes' CLI is a workaround for this issue.Additional Information
