This chapter includes the following sections:

About Launching UCS SCU

UCS Server Configuration Utility (SCU) is a bootable image based on a 32-bit Linux kernel and can be used to perform operations such as BIOS setup, configure RAID logical volume, install operating systems, and perform diagnostics on Cisco rack servers. It is designed to run on one server at a time.


Note


You can launch UCS-SCU from the F6 boot option on UCS C220 M3 and C240 M3 servers.


This section contains the following topics:

Obtaining UCS-SCU ISO Image From cisco.com

Before you launch the UCS-SCU on your system, you need to download the UCS-SCU ISO image.

To download the ISO file for your server online, follow these steps:

    Step 2   Click Unified Computing and Servers in the middle column.
    Step 3   Click Cisco UCS C-Series Rack-Mount Standalone Server Software in the right-hand column.
    Step 4   Click the name of your server model in the right-hand column.
    Step 5   In the Select a Software Type list, select Unified Computing System (UCS) Server Configuration Utility.

    The Download Software page appears listing the release version and the UCS-SCU image.

    Step 6   Click Download to download the ISO file.
    Step 7   Verify the information on the next page, then click Proceed With Download. If prompted, use your cisco.com credentials to log in.
    Step 8   Continue through the subsequent screens to accept the license agreement and browse to a location where you want to save the utilities zip file.
    Step 9   Extract the contents of the SCU zip file and note the location to which the SCU ISO file is saved.

    Launching UCS-SCU

    Using Cisco Flexible Flash

    About Cisco Flexible Flash

    Some C-Series Rack-Mount Servers support an internal Secure Digital (SD) memory card for storage of server software tools and utilities. The SD card is hosted by the Cisco Flexible Flash storage adapter.

    The SD storage is available to CIMC as four virtual USB drives. Three are preloaded with Cisco software and the fourth can hold a user-installed hypervisor or other content. The four virtual drives are as follows:

    • Cisco UCS Server Configuration Utility (bootable)
    • User-installed (may be bootable)
    • Cisco drivers (not bootable)
    • Cisco Host Upgrade Utility (bootable

    The Cisco Flexible Flash card is built into the rack server and allows the utility software to be pre-loaded at the factory during the manufacturing process.

    Alternatively, the utility software can be made available online along with the rest of the firmware updates. These updates can then be downloaded to the storage on the Cisco Flexible Flash card through the UCS-SCU GUI.

    Launching UCS-SCU From Cisco Flexible Flash

    To load the UCS-SCU from the Cisco Flexible Flash card, follow these steps

    Procedure
      Step 1   During startup, press F6 to enter the boot selection menu.

      The boot selection menu appears.

      Step 2   Use the arrow keys to select SCU, and then press Enter.
      Note   

      The Drivers option in the F6 boot selection screen is not a bootable option. If you select this option accidentally, you should restart your server as a workaround and select a different option. The HUU and SCU options are bootable. Use either of these options to boot the application with the images you downloaded and flashed to the SD card of your system. See Launching UCS-SCU From Cisco Flexible Flash for information on downloading the latest images of SCU and HUU to the SD card on your server


      Using Virtual Media

      About KVM Console

      You can use KVM Console to launch the UCS-SCU application with virtual media.

      KVM Console is an interface accessible from CIMC that emulates a direct keyboard, video, and mouse (KVM) connection to the server. KVM Console allows you to connect to the server from a remote location.


      Note


      KVM Console requires Java Runtime Environment (JRE) version 1.5.0 or higher.


      KVM Console has the following tabs:

      • KVM—This tab displays the UCS-SCU application when the application is booted.
      • Virtual Media—This tab allows you to map the following to a virtual drive:
        • CD/DVD on your computer or your network
        • Disk image files (ISO or IMG files) on your computer or your network
        • USB flash drive on your computer

      Entering Virtual KVM Console

      To enter the Virtual KVM Console, follow these steps:

      Procedure
        Step 1   Log in to CIMC.
        Step 2   Click Launch KVM Console.

        Virtual KVM Console displays the server console.


        Launching UCS-SCU From KVM

        To boot the UCS-SCU application using virtual KVM Console, follow these steps:

        Before You Begin

        Before you begin, download the UCS-SCU ISO image file from cisco.com. For information on how to download the image, go to the Obtaining UCS-SCU ISO Image From cisco.com

        Procedure
          Step 1   Log in to CIMC from your desktop.
          Step 2   Click Launch KVM Console to launch KVM Console
          Step 3   Click the Virtual Media tab.

          The Virtual Media tab opens.

          Step 4   Click Add Image.
          Step 5   Navigate to and select the ISO file and click Open to mount the image.
          Step 6   In the Client View section, select the check box in the Mapped column for the ISO file that you added and then wait for the mapping to complete.

          KVM Console displays the progress in the Details section.

          Step 7   Reboot the server by clicking in the CIMC.
          Step 8   Press F6 when the server starts to select a boot device.

          The boot selection menu appears.

          Step 9   Use the arrow keys to select Cisco Virtual CD/DVD and then press Enter.

          The server boots using the UCS-SCU image and launches the application in the KVM tab.


          Using Physical Media

          To launch the application on your server using a physical CD/DVD, follow these steps:

          Before You Begin

          Before you begin, do the following:

          • Download the UCS-SCU ISO image file from the Cisco Web site. For information on how to download the image, go to the “Obtaining ISO Image From cisco.com”
          • Create an .iso CD using an application that burns .iso CDs.
          Procedure
            Step 1   Connect the USB DVD drive to the server through the USB port.
            Step 2   Insert the physical media on to your DVD drive.
            Step 3   Restart the server and press F6 to enter the boot selection menu. Select CDROM drive as the boot device.

            The server boots using the UCS-SCU image and starts the application.


            Exiting UCS-SCU

            To exit the UCS-SCU application, follow these steps:

            Procedure
