Not able to define Mysql server node IP to Hashicorp HA node configuration

Setup is with 2 vault and mysql storage. We created mysql storage with mysql level DB cluster and have three node IPs.

Following configuration value not working Max_idle_connection value of no effect.

storage “mysql” {
database = “vault”
username = “uvault”
password = “vau20@19”
address = “”
ha_enabled = “true”
lock_table = “vault_lock”
max_idle_connections = “10”
max_connection_lifetime = “360000”

How to give IPs of three nodes of MYSQL in vault configuration file?

I think this it not possible/ implemented. You’ll have to deliver an address pointing to a proxy (mysqlrouter, proxysql) that should handle the connection to the three mysql nodes. Just a theory.
