        Recovering from a Corrupted BIOS


        Note

        This procedure is not available in some server models.

        In addition to this procedure, there are three other methods for recovering from a corrupted BIOS:

        • Use the Cisco Host Upgrade Utility (HUU). This is the recommended method.

        • Use the Cisco IMC CLI interface.

        • If your server model supports it, use the BIOS recovery function of the hardware jumper on the server motherboard. For instructions, see the Cisco UCS Server Installation and Service Guide for your server model.

        Before You Begin

        • You must be logged in as admin to recover corrupt BIOS.

        • Have the BIOS recovery ISO image ready. You will find the BIOS recovery ISO image under the Recovery folder of the firmware distribution package.

        • Schedule some down time for the server because it will be powered cycled at the end of the recovery procedure.

        Procedure
          Step 1   In the Navigation pane, click the Server tab.
          Step 2   On the server tab, click BIOS.

          The BIOS page appears.

          Step 3   In the Actions area, click Recover Corrupt BIOS.

          The Recover Corrupt BIOS wizard appears.

          Step 4   Use the Recover Corrupt BIOS wizard to recover your corrupt BIOS.

          Resetting Cisco IMC to Factory Defaults

          On rare occasions, such as an issue with the current running firmware, troubleshooting a server may require you to reset the Cisco IMC 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 Cisco IMC, you are logged off and must log in again. You may also lose connectivity and may need to reconfigure the network settings.

          When you upgrade from version 1.5(1) to version 1.5(2), the hostname in the Cisco IMC interface is retained as is. However, after upgrading to version 1.5(2), if you do a factory reset, the hostname changes to CXXX-YYYYYY format, where XXX is the model number and YYYYYY is the serial number of the server.

          When you downgrade from version 1.5(2) to version 1.5(1), the hostname is retained as is. However, if you do a factory reset, the hostname changes to ucs-cxx-mx format.


          Note

          If you reset Cisco IMC 1.5(x), 2.0, and 2.0(3) versions to factory defaults, Shared LOM mode is configured by default. For C3160 servers, if you reset Cisco IMC to factory defaults, Dedicated mode is configured to Full duplex with 100 Mbps speed by default.

          Before You Begin

          You must log in as a user with admin privileges to reset the Cisco IMC to factory defaults.

          Procedure
            Step 1   In the Navigation pane, click the Admin tab.
            Step 2   On the Admin tab, click Utilities.
            Step 3   In the Actions area of the Utilities pane, click Reset Cisco IMC to Factory Default Configuration.
            Step 4   Click OK.

            A reboot of Cisco IMC while the host is performing BIOS POST (Power on Self Test) or is in EFI shell will turn off the host for a short amount of time. Cisco IMC will power on when it is ready.

            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

            • Event management

            • SNMP

            Exporting the Cisco IMC Configuration


            Note
