You can use the maintenance console to configure network settings, to configure and manage the system on which Unified Manager is installed, and to perform other maintenance tasks that help you prevent and troubleshoot possible issues.
More information
What functionality the maintenance console provides
The Unified Manager maintenance console enables you to maintain the settings on your Unified Manager system and to make any necessary changes to prevent issues from occurring.
What the maintenance user does
The maintenance user is created during the installation of Unified Manager on a Red Hat Enterprise Linux or CentOS system. The maintenance user name is the "umadmin" user. The maintenance user has the Application Administrator role in the web UI, and that user can create subsequent users and assign them roles.
Diagnostic user capabilities
The purpose of diagnostic access is to enable technical support to assist you in troubleshooting, and you should only use it when directed by technical support.
Accessing the maintenance console
If the Unified Manager user interface is not in operation, or if you need to perform functions that are not available in the user interface, you can access the maintenance console to manage your Unified Manager system.
Accessing the maintenance console using the vSphere VM console
If the Unified Manager user interface is not in operation, or if you need to perform functions that are not available in the user interface, you can access the maintenance console to reconfigure your virtual appliance.
Maintenance console menus
The maintenance console consists of different menus that enable you to maintain and manage special features and configuration settings of the Unified Manager server.
Changing the umadmin password on Linux systems
For security reasons, you must change the default password for the Unified Manager umadmin user immediately after completing the installation process. If necessary, you can change the password again anytime later.
Adding network interfaces
You can add new network interfaces if you need to separate network traffic.
Adding disk space to the Unified Manager database directory
The Unified Manager database directory contains all of the health and performance data collected from ONTAP systems. Some circumstances may require that you increase the size of the database directory.
