      Resetting to Factory Default

      On rare occasions, such as an issue with the current running firmware, troubleshooting a server may require you to reset the chassis or BMC to the factory default. When this happens, all user-configurable settings are reset.

      This procedure is not part of the normal server maintenance. After you reset the chassis or BMC, you are logged off and must log in again. You may also lose connectivity and may need to reconfigure the network settings. Some of the inventory information may not be available during this transition.

      When you reset the BMC to factory settings, the serial number is displayed in the Cisco IMCXXXXXX format, where XXXXXX is the serial number of the server.

      Before You Begin

      You must log in as a user with admin privileges to reset the chassis or BMC to factory defaults.

      Procedure
        Step 1   In the Navigation pane, click the Admin menu.
        Step 2   In the Admin menu, click Utilities.
        Step 3   In the Actions area of the Utilities pane, click Reset to Factory Default.
        Step 4   In the Reset to Factory Default dialog box, review the following information:

        Actions

        Description

        Reset to factory Default Setting of drop-down list

        Allows you to select the chassis or BMCs for which you want to reset the factory default setting. This can be one of the following:

        • Chassis

        • BMC1

        • BMC2

        Step 5   Click Reset to reset the selected component to the factory-default settings.

        A reboot of Cisco IMC while the host is performing BIOS POST (Power on Self Test) or is in EFI shell powers down the host for a short amount of time. Cisco IMC powers on when it is ready. Upon restart, the network configuration mode is set to Cisco Card mode by default.

        Exporting and Importing the Cisco IMC Configuration

        Exporting and Importing the Cisco IMC Configuration

        To perform a backup of the Cisco IMC configuration, you take a snapshot of the system configuration and export the resulting Cisco IMC configuration file to a location on your network. The export operation saves information from the management plane only; it does not back up data on the servers. Sensitive configuration information such as user accounts and the server certificate are not exported.

        You can restore an exported Cisco IMC configuration file to the same system or you can import it to another Cisco IMC system, provided that the software version of the importing system is the same as or is configuration-compatible with the software version of the exporting system. When you import a configuration file to another system as a configuration template, you must modify system-specific settings such as IP addresses and host names. An import operation modifies information on the management plane only.

        The Cisco IMC configuration file is an XML text file whose structure and elements correspond to the Cisco IMC command modes.

        When performing an export or import operation, consider these guidelines:

        • You can perform an export or an import while the system is up and running. While an export operation has no impact on the server or network traffic, some modifications caused by an import operation, such as IP address changes, can disrupt traffic or cause a server reboot.

        • You cannot execute an export and an import simultaneously.

        You can perform an import or an export operation on the following features:

        • Cisco IMC version


          Note

          You can only export this information.

        • Network settings

        • Technical support

        • Logging control for local and remote logs

        • Power policies

        • BIOS - BIOS Parameters


          Note

          Precision boot is not supported.

        • Communication services

        • Remote presence

        • User management - LDAP

        • SNMP

        • Dynamic Storage Configuration

        • Chassis Description
