Configure OpenManage Enterprise by using Text User Interface

The Text User Interface (TUI) tool provides a text interface to change the Administrator password, view appliance status and network configuration, configure networking parameters, enable field service debug request, select the primary network, and to configure the appliance for automatic discovery of the servers in your network.

When you boot the system for the first time from the TUI, you are prompted to accept the End User License Agreement (EULA). Next, change the administrator password and configure network parameters for the appliance and load the web console in a supported browser to get started. Only users with OpenManage Administrator privileges can configure OpenManage Enterprise.

On the TUI interface, use the arrow keys or press Tab to go to the next option on the TUI, and press Shift + Tab to go back to the previous options. Press Enter to select an option. The Space bar switch the status of a check box.

NOTE
  • To configure IPv6, ensure that it is already configured by a vCenter server.
  • By default, the last discovered IP of a device is used by OpenManage Enterprise for performing all operations. To make any IP change effective, you must rediscover the device.

You can configure OpenManage Enterprise by using the TUI. The TUI screen has the following options:

Table 1. Text User Interface optionsThis table list all the Text User Interface options.
Options Descriptions
Change the Admin Password Select Change the Admin Password screen to enter a new password and confirm the password.

For the first time, you must change the password by using the TUI screen.

Display Current Appliance Status Select Display Current Appliance Status to view the URL and the status of the appliance. You can also view statuses of the Task Execution, Event Processing, Tomcat, Database, and Monitoring services.
Display Current Network Configuration Select Display Current Network Configuration to view the IP configuration details.

Choose Network Adapter menu lists all the available network adapters. Clicking on a network adapter will display its current settings.

Set Appliance Hostname Select Set Appliance Hostname to configure the appliance hostname on the DNS. This field supports the following valid characters for host names: alphanumeric (a-z, A-Z, 0-9), periods ( . ), and dashes ( - ).
NOTE Using periods will designate domain name information. If the appliance DNS information is configured statically rather than getting domain details from DHCP, you must configure the hostname using the fully qualified domain name (FQDN) so that the domain search information can be populated.
Set Networking Parameters Select Set Networking Parameters to reconfigure the network adapters.

Choose Network Adapter menu lists all the available networks adapters. Select a network adapter, reconfigure its network parameters, and select Apply to save the changes to the appropriate interface.

By default, only IPv4 is enabled on primary network interface with a private static IP in the appliance. However, if a new network interface is added, both IPv4 and IPv6 are enabled for multihoming.

If the OpenManage Enterprise appliance fails to acquire a IPv6 address, check if the environment is configured for router advertisements to have the managed bit (M) turned on. Network Manager from current Linux distributions causes a link failure when this bit is on, but DHCPv6 is not available. Ensure that DHCPv6 is enabled on the network or disable the managed flag for router advertisements.

NOTE
  • DNS configuration is only available on the primary network interface. If DNS resolution is wanted on this interface, all host names must be resolvable by the DNS server configured on the primary interface.
Select Primary Network Interface Select Primary Network Interface allows you to designate a primary network.

Primary interface selection gives priority to the selected interface in terms of routing and is used as the default route. This interface will have the routing priority if there is any ambiguity. The primary interface is also expected to be the 'public facing' interface which allows for corporate network/internet connectivity. Different firewall rules are applied to the primary interface, which allow for tighter access control such as access restriction by IP range.

NOTE If multihoming is enabled, the appliance can be accessed from two networks. In this case, the primary interface is used by the appliance for all external communication and when proxy settings are used. For more information about multihoming on OpenManage, seeRemote script execution with Dell EMC OpenManage Enterprise technical white paper on the support site.
Configure Static Routes Select Configure Static Routes if the networks require a static route to be configured to reach a specific subnet over the IPv4 and IPv6 networks.
NOTE A maximum of 20 static routes per interface is supported.
Configure Server Initiated Discovery Select Configure Server Initiated Discovery to allow the appliance to automatically register the required records with the configured DNS server.
NOTE
  • Ensure that the appliance is registered with DNS, and can dynamically update records.
  • The target systems must be configured to request registration details from DNS.
  • To change the DNS Domain Name, ensure Dynamic DNS registration is enabled on the DNS server. Also, for appliance to be registered on the DNS server, select the Nonsecure and secure option under Dynamic updates.
Enable Field Service Debug (FSD) Mode Select Enable Field Service Debug (FSD) Mode for console debugging. For more information, see Field service debug workflow.
Restart Services Select Restart Services with the following options to restart the services and networking:
  • Restart All Services
  • Restart Networking
Setup Debug Logging Select Setup Debug Logging using the following options :
  • Enable Debug Logs—to collect the Debug logs of the application monitoring tasks, events, and the task execution history.
  • Disable Debug Logs—to disable the Debug logs.
  • Enable SCP Retention—to collect the template .XML files.
  • Disable SCP Retention—to disable the SCP retention.

You can download the debug logs by clicking Monitor > Audit Logs > Export > Export Console Logs in OpenManage Enterprise.

Change keyboard layout Select Change keyboard layout to change the keyboard layout if needed.
Reboot the Appliance Select Reboot the Appliance to restart the appliance.
NOTE After running a command to restart the services, the TUI may display the following message: NMI watchdog: BUG: soft lockup - CPU#0 stuck for 36s! [java:14439].

The soft lockup issue likely occurs as a result of the hypervisor being overloaded. In such situations, it is recommended to have at least 16 GB of RAM and CPU of 8000 MHz reserved to the OpenManage Enterprise appliance. It is also recommended that the OpenManage Enterprise appliance be restarted when this message is displayed.
