A message is displayed stating that the system cannot be accessed during a failover. Troubleshooting in chassis The Troubleshoot option on the OME-Modular home page enables you to use the following options to resolve issues that occur in the chassis: • Extract Log-Use this option to extract application logs and save them to the NFS or CIFS locations on the network. • Diagnostic Commands-Use this option to run diagnostic commands and parameters to troubleshoot the chassis network. • Reset Management Module-Use this option to reboot the management module (MM) in a single management module configuration, and perform a failover in a dual MM configuration. NOTE: During a factory reset process, the synchronization takes about 3-5 minutes. During this period, the serial, KVM, and Quick Sync interfaces do not accept the factory password and the login attempt fails. • Terminate Serial Connection-Use this option to end the existing serial sessions. Blinking LEDs You can use the Blink LED option on the OME-Modular home page to turn off or turn on the chassis LED. Interfaces to access OME-Modular After configuring the network settings in OME-Modular, you can remotely access OME-Modular using various interfaces. The following table lists the interfaces that you can use to remotely access OME-Modular. Table 2. Management module Interfaces Interface Web interface Description Provides remote access to OME-Modular using a graphical user interface. The web interface is built into the OME-Modular firmware and is accessed through the NIC interface from a supported web browser on the management station. The number of user sessions allowed for each interface is: • Web interface - 6 • RESTful API - 32 • SSH - 4 For a list of supported web browsers, see the Supported browsers section in the OME Modular for PowerEdge MX7000 Chassis Release Notes available at www.dell.com/ openmanagemanuals. Remote RACADM command line interface LCD Use this command line utility to manage OME-Modular and its components. You can use remote or firmware RACADM: • Remote RACADM is a client utility that runs on a management station. It uses the out-ofband network interface to run RACADM commands on the managed system and uses the HTTPs channel. The -r option runs the RACADM command over a network. • Firmware RACADM is accessible by logging in to OME-Modular using SSH or telnet. You can run the firmware RACADM commands without specifying the OME-Modular IP, user name, or password. After you enter the RACADM prompt, you can directly run the commands without the racadm prefix. NOTE: A log for remote racadm session (login or logout) is displayed in the Audit Logs page, irrespective of the remote racadm status. However, the feature does not work if the remote racadm option is disabled. Use the LCD on the front panel to: 28 Logging in to OME-Modular

Troubleshooting in chassis

The Troubleshoot option on the OME–Modular home page enables you to use the following options to resolve issues that occur in the

chassis:

•

Extract Log—Use this option to extract application logs and save them to the NFS or CIFS locations on the network.

•

Diagnostic Commands—Use this option to run diagnostic commands and parameters to troubleshoot the chassis network.

•

Reset Management Module—Use this option to reboot the management module (MM) in a single management module

conﬁguration,

and perform a failover in a dual MM

conﬁguration.

NOTE:

During a factory reset process, the synchronization takes about 3-5 minutes. During this period, the serial, KVM,

and Quick Sync interfaces do not accept the factory password and the login attempt fails.

•

Terminate Serial Connection—Use this option to end the existing serial sessions.

Blinking LEDs

You can use the

Blink LED

option on the OME–Modular home page to turn

oﬀ

or turn on the chassis LED.

Interfaces to access OME-Modular

After

conﬁguring

the network settings in OME–Modular, you can remotely access OME-Modular using various interfaces. The following

table lists the interfaces that you can use to remotely access OME–Modular.

preﬁx.

NOTE:

A log for remote racadm session (login or logout) is displayed in the Audit

Logs page, irrespective of the remote racadm status. However, the feature does not

work if the remote racadm option is disabled.
