Server /cimc/tech-support # start
    What to Do Next

    Provide the generated report file to Cisco TAC.

    Rebooting the CIMC

    On rare occasions, such as an issue with the current running firmware, troubleshooting a server may require you to reboot the CIMC. This procedure is not part of the normal maintenance of a server. After you reboot the CIMC, you are logged off and the CIMC will be unavailable for a few minutes.


    Note

    If you reboot the CIMC while the server is performing power-on self test (POST) or is operating in the Extensible Firmware Interface (EFI) shell, the server will be powered down until the CIMC reboot is complete.

    Procedure
       Command or ActionPurpose
      Step 1Server# scope cimc  

      Enters the CIMC command mode.

       
      Step 2Server /cimc # reboot  

      The CIMC reboots.

       

      This example reboots the CIMC:

      Server# scope cimc
Server /cimc # reboot

      Clearing the BIOS CMOS

      On rare occasions, troubleshooting a server may require you to clear the server's BIOS CMOS memory. This procedure is not part of the normal maintenance of a server.

      Procedure
         Command or ActionPurpose
        Step 1Server# scope bios  

        Enters the bios command mode.

         
        Step 2Server /bios # clear-cmos  

        After a prompt to confirm, clears the CMOS memory.

         

        This example clears the BIOS CMOS memory:

        Server# scope bios
Server /bios # clear-cmos

This operation will clear the BIOS CMOS.
Note: Server should be in powered off state to clear CMOS.

        Recovering from a Corrupted BIOS

        Before You Begin
        • You must be logged in as admin to recover from a corrupted 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 power cycled at the end of the recovery procedure.
        Procedure
           Command or ActionPurpose
          Step 1Server# scope bios  

          Enters the bios command mode.

           
          Step 2Server# recover  

          Launches a dialog for loading the BIOS recovery image.

           

          This example shows how to recover from a corrupted BIOS:

          Server# scope bios
Server /bios # recover
This operation will automatically power on the server to perform BIOS FW recovery.

          What to Do Next

          Power cycle or reset the server.

          Resetting the CIMC to Factory Defaults

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

          Procedure
             Command or ActionPurpose
            Step 1Server# scope cimc  

            Enters the CIMC command mode.

             
            Step 2Server /cimc # factory-default  

            After a prompt to confirm, the CIMC resets to factory defaults.

             

            The CIMC factory defaults include the following conditions:
            • SSH is enabled for access to the CIMC CLI. Telnet is disabled.
            • HTTPS is enabled for access to the CIMC GUI.
            • A single user account exists (user name is admin , password is password ).
            • DHCP is enabled on the management port.
            • The boot order is EFI, CDROM, PXE (using LoM), FDD, HDD.
            • KVM and vMedia are enabled.
            • USB is enabled.
            • SoL is disabled.

            This example resets the CIMC to factory defaults:

            Server# scope cimc
Server /cimc # factory-default 
This operation will reset the CIMC configuration to factory default.
All your configuration will be lost.
Continue?[y|N]

            Exporting and Importing the CIMC Configuration

            Exporting and Importing the CIMC Configuration

            To perform a backup of the CIMC configuration, you take a snapshot of the system configuration and export the resulting CIMC 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 CIMC configuration file to the same system or you can import it to another CIMC 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 CIMC configuration file is an XML text file whose structure and elements correspond to the CIMC 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.

            Exporting the CIMC Configuration


            Note

            For security reasons, this operation does not export user accounts or the server certificate.

            Before You Begin

            Obtain the backup TFTP server IP address.

            If you want the option to restore the SNMP configuration information when you import the configuration file, make sure that SNMP is enabled on this server before you create the configuration file. If SNMP is disabled when you export the configuration, CIMC will not apply the SNMP values when the file is imported.

            Procedure
               Command or ActionPurpose
              Step 1 Server# scope cimc  

              Enters the CIMC command mode.

               
              Step 2 Server /cimc # scope import-export  

              Enters the import-export command mode.

               
              Step 3 Server /cimc/import-export # export-config tftp-ip-address path-and-filename  

              Starts the backup operation. The configuration file will be stored at the specified path and file name on the TFTP server at the specified IP address.

               

              To determine whether the export operation has completed successfully, use the show detail command. To abort the operation, type CTRL+C.

              This example shows how to back up the CIMC configuration:

              Server# scope cimc
Server /cimc # scope import-export
Server /cimc/import-export # export-config 192.0.2.34 /ucs/backups/cimc5.xml
Export config started. Please check the status using "show detail".
Server /cimc/import-export # show detail
Import Export:
    Operation: EXPORT
    Status: COMPLETED
    Error Code: 100 (No Error)
    Diagnostic Message: NONE

Server /cimc/import-export #

              Importing a CIMC Configuration

              Before You Begin

              If you want to restore the SNMP configuration information when you import the configuration file, make sure that SNMP is disabled on this server before you do the import. If SNMP is enabled when you perform the import, CIMC does not overwrite the current values with those saved in the configuration file.

              Procedure
                 Command or ActionPurpose
                Step 1 Server# scope cimc  

                Enters the CIMC command mode.

                 
                Step 2 Server /cimc # scope import-export  

                Enters the import-export command mode.

                 
                Step 3 Server /cimc/import-export # import-config tftp-ip-address path-and-filename  

                Starts the import operation. The configuration file at the specified path and file name on the TFTP server at the specified IP address will be imported.

                 

                To determine whether the import operation has completed successfully, use the show detail command. To abort the operation, type CTRL+C.

                This example shows how to import a CIMC configuration:

                Server# scope cimc
Server /cimc # scope import-export
Server /cimc/import-export # import-config 192.0.2.34 /ucs/backups/cimc5.xml
Import config started. Please check the status using "show detail".
Server /cimc/import-export #
