Its not a common scenario, but for atleast one or two customer you might have faced failed cluster discovery due to login. Two possible scenarios,
- Cluster nodes use different Administration password
- Cluster node with different Administration username/password
In the first scenario, each node is set with different administration password. For such scenarios change the admin password and keep it unique. To change the administration password use below command from CLI.
set password user admin
In the second scenario, each nodes use different username and password. changing the administration password is not difficult. but we cannot change the admin username which we created during the installation.
For such scenario, on all nodes create a user with privilege 1 and use same username and password.
create a new account test
note:- When you create a new user, make sure you login using this user and change the default password set through CLI.
Do a cluster discovery using the new administration user
note:- Admin user which you created during installation has privilege 4 . When creating a new user you can only have privilege 0 or 1.
