Managing Remote Presence

This chapter includes the following sections:

Managing the Virtual KVM

KVM Console

The KVM console is an interface accessible from the CIMC that emulates a direct keyboard, video, and mouse connection to the server. The KVM console allows you to connect to the server from a remote location. Instead of using CD/DVD or floppy drives physically connected to the server, the KVM console uses virtual media, which are actual disk drives or disk image files that are mapped to virtual CD/DVD or floppy drives. You can map any of the following to a virtual drive:

  • CD/DVD or floppy drive on your computer
  • Disk image files (ISO or IMG files) on your computer
  • USB flash drive on your computer
You can use the KVM console to install an operating system or hypervisor on the server and to do the following:
  • Access the BIOS setup menu by pressing F2 during bootup.
  • Access the CIMC Configuration Utility by pressing F8 during bootup.
  • Access the WebBIOS to configure RAID, by pressing the Ctrl and H keys during bootup.

Configuring the Virtual KVM

Before You Begin

You must log in as a user with admin privileges to configure the virtual KVM.

Procedure
     Command or ActionPurpose
    Step 1Server# scope kvm  

    Enters KVM command mode.

     
    Step 2Server /kvm # set enabled {yes | no}  

    Enables or disables the virtual KVM.

     
    Step 3Server /kvm # set encrypted {yes | no}  

    If encryption is enabled, the server encrypts all video information sent through the KVM.

     
    Step 4Server /kvm # set kvm-port port  

    Specifies the port used for KVM communication.

     
    Step 5Server /kvm # set local-video {yes | no}  

    If local video is yes, the KVM session is also displayed on any monitor attached to the server.

     
    Step 6Server /kvm # set max-sessions sessions  

    Specifies the maximum number of concurrent KVM sessions allowed. The sessions argument is an integer between 1 and 4.

     
    Step 7Server /kvm # commit  

    Commits the transaction to the system configuration.

     
    Step 8Server /kvm # show [detail]

        Server /kvm #             
        

        Configuring Virtual Media

        Before You Begin

        You must log in as a user with admin privileges to configure virtual media.

        Procedure
           Command or ActionPurpose
          Step 1Server# scope vmedia  

          Enters virtual media command mode.

           
          Step 2Server /vmedia # set enabled {yes | no}  

          Enables or disables virtual media. By default, virtual media is disabled.

          Note   

          Disabling virtual media detaches the virtual CD, virtual floppy, and virtual HDD devices from the host.

           
          Step 3Server /vmedia # set encryption {yes | no}  

          Enables or disables virtual media encryption.

           
          Step 4Server /vmedia # set low-power-usb-enabled {yes | no}  

          Enables or disables low power USB.

          Note   
          While mapping an ISO to a server which has a UCS VIC P81E card and the NIC is in Cisco Card mode:
          • If the low power USB is enabled, after mapping the ISO and rebooting the host the card resets and ISO mapping is lost. The virtual drives are not visible on the boot selection menu.
          • If the low power USB is disabled, after mapping the ISO, and rebooting the host and the CIMC, the virtual drivers appear on the boot selection menu as expected.
           
          Step 5Server /vmedia # commit  

          Commits the transaction to the system configuration.

           
          Step 6Server /vmedia # show [detail]  

          (Optional) Displays the virtual media configuration.

           

          This example configures virtual media encryption:

                Managing Serial over LAN

                Serial over LAN

                Serial over LAN (SoL) is a mechanism that enables the input and output of the serial port of a managed system to be redirected via an SSH session over IP. SoL provides a means of reaching the host console via the CIMC.

                Guidelines and Restrictions for Serial over LAN

                For redirection to SoL, the server console must have the following configuration:

                • Console redirection to serial port A
                • No flow control
                • Baud rate the same as configured for SoL
                • VT-100 terminal type
                • Legacy OS redirection disabled

                The SoL session will display line-oriented information such as boot messages, and character-oriented screen menus such as BIOS setup menus. If the server boots an operating system or application with a bitmap-oriented display, such as Windows, the SoL session will no longer display. If the server boots a command-line-oriented operating system (OS), such as Linux, you may need to perform additional configuration of the OS in order to properly display in an SoL session.

                In the SoL session, your keystrokes are transmitted to the console except for the function key F2. To send an F2 to the console, press the Escape key, then press 2.

                Configuring Serial Over LAN

                Before You Begin

                You must log in as a user with admin privileges to configure SoL.

                Procedure
                   Command or ActionPurpose
                  Step 1Server# scope sol  

                  Enters SoL command mode.

                   
                  Step 2Server /sol # set enabled {yes | no}  

                  Enables or disables SoL on this server.

                   
                  Step 3Server /sol # set baud-rate {9600 | 19200 | 38400 | 57600 | 115200}  

                  Sets the serial baud rate the system uses for SoL communication.

                  Note   

                  The baud rate must match the baud rate configured in the server serial console.

                   
                  Step 4Server /sol # commit  

                  Commits the transaction to the system configuration.

                   
                  Step 5Server /sol # show [detail]  

                  (Optional) Displays the SoL settings.

                   

                  This example configures SoL:

                  Server# scope sol
                  Server /sol # set enabled yes
                  Server /sol *# set baud-rate 115200
                  Server /sol *# commit
                  Server /sol # show
                  Enabled Baud Rate(bps)  
                  ------- --------------- 
                  yes     115200    
                  
                  Server /sol #            
                  

                  Launching Serial over LAN

                  Procedure
                     Command or ActionPurpose
                    Step 1Server# connect host  

                    Opens an SoL connection to the redirected server console port. You can enter this command in any command mode.

                     
                    What to Do Next

                    Press Ctrl and X keys to disconnect from SoL and return to the CLI session.


                    Note


                    When you enable SoL, the output from the serial port is redirected; therefore, when you try to session into the host from Cisco IOS CLI, you will not see any output.
