Logging In to a Compute Node, Pass-through Module, or Switch Module over SOL

Logging In to a Compute Node, Pass-through Module, or Switch Module over SOL

Scenarios

Connect cables to a compute node, pass-through module, or switch module in an E9000 chassis, and log in to the node or module by using the MM910 Serial over LAN (SOL) function for remote maintenance.

Prerequisites

  • You have used the floating IP address of the management module to log in to the MM910 CLI.
  • There is no jumper cap over the pins on the mainboard of the compute node, pass-through module, or switch module.
  • You have obtained the user name and password for logging in to the MM910. The default user name is root, and the default password is Huawei12#$.
  • You have obtained the user name and password for logging in to the compute node to be connected. The default user name is root, and the default password is Huawei12#$.
  • You have obtained the password for logging in to the pass-through module or switch module to be connected. The default password is Huawei12#$.

Procedure

  1. Log in to the MM910 CLI with the floating IP address of the MM910 over Secure Shell (SSH).

    This section uses PuTTY as an example for login over SSH. For details, see Logging In to a Server Over a Network Port by Using PuTTY.

  2. Log in to the SOL screen.

    telnet 0 1101
    *=====================================================================* 
     *             Welcome to SMM SOL Server                               * 
     *     Please log in with SMM account and password.                    * 
     *=====================================================================* 
      
      
     user name: 

    If you need to disconnect from the service terminal or server power supply after logging in to the SOL screen, exit the SOL screen first. Otherwise, re-logging in to the SOL screen will fail.

  3. Enter the user name and password.

    The screen for selecting a slot number is displayed.

    Log in Success! 
      
     *=========================================================================================================== 
           please input the SOL Blade1~Blade16(1 ~ 16), Blade1A~Blade16A(17 ~ 32), Swi1~Swi4(33 ~ 36) and COM#(n) 
           press Ctrl+R to return 
     *=========================================================================================================== 
      
      
     Blade1~Blade16(1 ~ 16) 
     Blade1A~Blade16A(17 ~ 32) 
     Swi1~Swi4(33 ~ 36) 
     Please input your choice:
    The slot numbers are described as follows:
    • Numbers 1 to 32 indicate the compute nodes in slots 1 to 32 respectively.
    • Numbers 33 to 36 indicate the switch modules in slots 1E, 2X, 3X, and 4E respectively.

  4. Enter the slot number of the compute node, passthrough module, or switch module, and press Enter.

    • If you enter a compute node slot number, the following serial port information is displayed:
       1 systemcom 
       2 RAIDcom 
       3 BMCcom 
       4 Exboardcom 

      Or

       1 SYS COM 
       2 BMC COM 

      Or

       1 systemcom 
       2 BMCcom 

      If you enter a switch module slot, the following serial port information is displayed:

       1 BMCcom 
       2 fabriccom 
       3 basecom 
       4 FCcom

      Or

       1 BMCcom 
       2 fabriccom 

      Or

       1 BMCcom 
       2 fabriccom 
       3 basecom 

    • If you enter a pass-through module slot, the following serial port information is displayed:
      1 BMCcom

  5. Select a serial port by entering a number, and press Enter.

    The serial port screen is displayed. On this screen, you can configure and query data, or perform other operations.
    NOTE:

    You can press Ctrl+R once to return to the slot number selection screen, or press Ctrl+R twice to exit the SOL screen.
