The root password was changed on the backup node on OS level.


There is no way to change the root password on the Cloud Infrastructure nodes using the UI in the current module version.

The feature will be implemented in the scope of the request CCU-20908: "Simple password change procedure for BN/HN".

Contact your Technical Account Manager to request a workaround.
