Log in to OpenManage Enterprise

When you boot the system for the first time from the Text User Interface (TUI), you are prompted to accept the EULA, and then change the administrator password. If you are logging in to OpenManage Enterprise for the first time, you must set the user credentials through

the TUI. See Configure OpenManage Enterprise by using Text User Interface .

CAUTION: If you forget the administrator password, it cannot be recovered from the OpenManage Enterprise appliance.

1. Start the supported browser.

2. In the Address box, enter the OpenManage Enterprise appliance IP address.

3. On the login page, type the login credentials, and then click Log in .

NOTE: The default user name is admin .

If you are logging in to OpenManage Enterprise for the first time, the Welcome to OpenManage Enterprise page is displayed. Click Initial

Settings

, and complete the basic configuration setup. See Configure OpenManage Enterprise

. To discover the devices, click Discover

Devices .

NOTE: If incorrect OpenManage Enterprise login credentials are entered, your OpenManage Enterprise account is locked and you will not be able to log in until completing the lockdown period. By default, the lockdown duration is 900 seconds. To change this duration, see

Set the login security properties

.

Configure OpenManage Enterprise by using Text

User Interface

The Text User Interface (TUI) tool provides you a text interface to change the admin password, view appliance status and network configuration, configure networking parameters, and enable field service debug request.

NOTE: 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.

1. Before logging into the TUI, accept EULA when prompted. In the next Choose keyboard layout screen, change the keyboard layout if needed.

a) On the Change admin password screen, enter the new password and confirm the password.

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

b) Use the arrow keys or press Tab to select Apply .

c) When prompted for confirmation, select Yes , and then press Enter .

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

• Change the Admin Password

• Display Current Appliance Status shows the appliance service status.

• Display Current Network Configuration shows the IP configuration details.

Get started with OpenManage Enterprise 23

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

• Set Networking Parameters

• Choose Network Adapter menu lists all the available networks adapters. Clicking on a network adapter allows you to reconfigure its network parameters and apply the changes to the appropriate interface.

NOTE:

• 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.

• DNS configuration is only available on the primary network interface. If DNS resolution is desired on this interface, all host names must be resolvable by the DNS server configured on the primary interface.

• Select Primary Network Interface allows you 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 in the event of 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.

• Configure Static Routes can be used 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.

• Enable Field Service Debug (FSD) Mode

• Reboot the Appliance

NOTE: Possibly after running a command to restart the services, it may be observed that the TUI displays the following message: NMI watchdog: BUG: soft lockup - CPU#0 stuck for 36s! [java:14439].

This 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.

• Setup Debug Logging

• Enable Debug Logs

• Disable Debug Logs

• Enable SCP Retention

• Disable SCP Retention

• Services Restart

• Restart All Services

• Restart Networking

2. To confirm the current appliance administrator password, select Change the Admin Password , and then enter the password. Press

Tab and select Continue .

3. On the TUI screen: a) To view appliance status and the IPv4 and IPv6 statuses and addresses, select Current Appliance Status .

b) To configure network interface, select Set Networking Parameters .

On the Configure Network Interface screen, to enable IPv4, or IPv6, or both, press Enter . Select Apply .

NOTE:

• Multihoming is enabled and the appliance can be accessed from two networks. It should be noted that the mandatory primary interface is used by the appliance for all external communication and when proxy settings are used.

• 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.

• 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.

• To perform any write operations on TUI, ensure that you type the admin password, and then configure IPv4 or

IPv6.

24 Get started with OpenManage Enterprise

• To configure IPv6, ensure that it is already configured by a vCenter server.

• In an IPv6 environment, when a Router Advertisement is configured for stateless configuration of multiple

IPv6 IPs on a port, iDRAC supports a maximum of 16 IPs addresses. In such a case, OpenManage Enterprise displays only the last discovered IP and uses that IP as the out-of-band interface to iDRAC.

• 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.

c) To enable console debug, select Enable Field Service Debug (FSD) Mode . See

Field service debug workflow

.

d) To collect the debug logs of the application, monitoring tasks, events, and task execution history, select Setup Debug Logging .

In addition, to collect the template .XML files, select the Enable SCP retention option under Setup Debug Logging . You can download the debug logs by clicking Monitor > Audit Logs > Export > Export Console Logs in OpenManage Enterprise.

e) To restart OpenManage Enterprise, select Reboot the Appliance .
