Exporting Technical Support Data

Perform this task when requested by the Cisco Technical Assistance Center (TAC). This utility creates a summary report containing configuration information, logs and diagnostic data that will help TAC in troubleshooting and resolving a technical issue.

Important:

If any firmware or BIOS updates are in progress, do not export the technical support data until those tasks are complete.

Procedure
     Command or ActionPurpose
    Step 1Server # scope chassis  

    Enters chassis command mode.

     
    Step 2Server /chassis # scope tech-support  

    Enters the tech-support command mode.

     
    Step 3Server /chassis/tech-support # set collect-from {all | cmc | peercmc | bmc1 | bmc2}  

    Specifies the component for which the technical support data has to be exported.

     
    Step 4Server /chassis/tech-support # set remote-ip ip-address  

    Specifies the IP address of the remote server on which the technical support data file should be stored.

     
    Step 5Server /chassis/tech-support # set remote-path path/filename  

    Specifies the file name in which the support data should be stored on the remote server. When you enter this name, include the relative path for the file from the top of the server tree to the desired location.

    Tip   

    To have the system auto-generate the file name, enter the file name as default.tar.gz.

     
    Step 6Server /chassis/tech-support # set remote-protocol protocol  
    Specifies the protocol to connect to the remote server. It can be of the following types:

    • TFTP

    • FTP

    • SFTP

    • SCP

    • HTTP

    Note   

    The Cisco UCS C-Series server now supports fingerprint confirmation of the server when you update firmware through a remote server. This option is available only if you choose SCP or SFTP as the remote server type.

    If you chose SCP or SFTP as the remote server type while performing this action, a prompt with the message Server (RSA) key fingerprint is <server_finger_print _ID> Do you wish to continue? Click y or n depending on the authenticity of the server fingerprint.

    The fingerprint is based on the host's public key and helps you to identify or verify the host you are connecting to.

     
    Step 7Server /chassis/tech-support # set remote-username name  

    Specifies the user name on the remote server on which the technical support data file should be stored. This field does not apply if the protocol is TFTP or HTTP.

     
    Step 8Server /chassis/tech-support # set remote-password password  

    Specifies the password on the remote server on which the technical support data file should be stored. This field does not apply if the protocol is TFTP or HTTP.

     
    Step 9Server /chassis/tech-support # commit  

    Commits the transaction to the system configuration.

     
    Step 10Server /chassis/tech-support # start  

    Begins the transfer of the data file to the remote server.

     
    Step 11Server /chassis/tech-support # show detail   (Optional)

    Displays the progress of the transfer of the data file to the remote server.

     
    Step 12Server /chassis/tech-support # cancel   (Optional)

    Cancels the transfer of the data file to the remote server.

     

    This example creates a technical support data file and transfers the file to a TFTP server: 

    Server# scope chassis
Server /chassis # scope tech-support 
Server /chassis/tech-support # set collect-from all
Server /chassis/tech-support* # set remote-ip 192.0.20.41

    Rebooting the Cisco IMC

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


    Note

    If you reboot the Cisco IMC 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 Cisco IMC reboot is complete.

    Procedure
       Command or ActionPurpose
      Step 1Server # scope server {1 | 2}  

      Enters server command mode of server 1 or 2.

       
      Step 2Server /server # scope bmc  

      Enters bmc command mode.

       
      Step 3Server /server/bmc # reboot  

      The Cisco IMC reboots.

       

      This example reboots the Cisco IMC: 

      Server# scope server 1
Server /server # scope bmc
Server /server/bmc # 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 server {1 | 2}  

        Enters server command mode of server 1 or 2.

         
        Step 2Server /server # scope bios  

        Enters the bios command mode.

         
        Step 3Server /server/bios # clear-cmos  

        After a prompt to confirm, clears the CMOS memory.

         

        This example clears the BIOS CMOS memory: 

        Server# scope server 2
Server/server # scope bios
Server /server/bios # clear-cmos

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

        Resetting the BMC to factory Defaults

        On rare occasions, such as an issue with the current running firmware, troubleshooting a server may require you to reset the 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 BMC, 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 server {1 | 2}  

          Enters server command mode of server 1 or 2.

           
          Step 2Server /server # scope bmc  
          Enters bmc command mode.
          Note   

          Depending on the server number you have chosen, enters the BMC1 or BMC2 mode.

           
          Step 3Server /server/bmc # factory-default  

          After a prompt to confirm, the BMC resets to factory defaults. All your BMC configuration is lost and some of the inventory information may not be available until the server is powered on or power cycled.

           

          This example resets BMC1 to factory defaults: 

          Server# scope server 1
Server /server # scope bmc
Server /server/bmc # factory-default
This operation will reset the Server BMC configuration to factory default.
All your configuration will be lost. Some inventory information may
not be available until the server is powered on or power cycled.

          Resetting CMCs to Factory Defaults

          On rare occasions, such as an issue with the current running firmware, troubleshooting a server may require you to reset the CMCs 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 CMC, 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 chassis  

            Enters the chassis command mode.

             
            Step 2Server /chassis # factory-default  

            After a prompt to confirm, the CMCs resets to factory defaults. All your CMC configuration is lost and the network configuration mode is set to Cisco Card mode by default.

             

            The CMCs factory defaults include the following conditions:

            • SSH is enabled for access to the Cisco IMC CLI. Telnet is disabled.

            • HTTPS is enabled for access to the Cisco IMC GUI.

            • A single user account exists (user name is admin , password is password ).

            • DHCP is enabled on the management port.

            • The previous actual boot order is retained.

            • KVM and vMedia are enabled.

            • USB is enabled.

            • SoL is disabled.

            This example resets the CMCs to factory defaults: 

            Server# scope chassis
Server /chassis # factory-default 
This operation will reset the CMC configuration to factory default.
All your configuration will be lost.

                    Generating Non-Maskable Interrupts to the Host

                    In some situations, the server might hang and not respond to traditional debug mechanisms. By generating a non maskable interrupt (NMI) to the host, you can create and send a crash dump file of the server and use it to debug the server.

                    Depending on the type of operating system associated with the server, this task might restart the OS.

                    Procedure
                       Command or ActionPurpose
                      Step 1Server # scope chassis  

                      Enters chassis command mode.

                       
                      Step 2Server /chassis # scope server {1 | 2}  

                      Enters server command mode of server 1 or 2.

                       
                      Step 3Server /chassis/server # generate-nmi  

                      Generates the crash dump file for the server.

                      To use this command, the server must be powered on, and you must be logged in as an administrator.

                       

                      This example shows how to generate NMI signals to the host: 

                      Server # scope chassis
Server /chassis # scope server 2
Server /chassis/server # generate-nmi
This operation will send NMI to host and may cause reboot of OS
OS reboot depends on it's NMI configuration
