Chapter 3. System Configuration from the SMN

This chapter walks you through steps to use KVM to enable remote console access from the system management node (SMN) to an SGI Altix UV 100 or an SGI Altix UV 1000 system. It covers the following topics:

Enabling a Remote Console


Note: The enabling a remote console feature is currently NOT available. A new BaseIO firmware image will be released in the near future to enable this capability.


This section describes how to use KVM to enable remote console access.

Procedure 3-1. Enabling a Remote Console

    To enable a remote console to your SGI Altix UV system, perform the following steps:

    1. Establish a network connection to the SMN, as follows:

      # ssh -X sysco@uv-system-smn

      The password set out of the factory is sysco.

    2. From the SMN, launch the Mozilla Firefox web browser, as follows:

      sysco@system-smn:~/hw>firefox

    3. Enter the IP address of the BaseIO node baseboard management controller (BMC), similar to the following:

      http://192.168.1.200

      To determine the IP address of the BaseIO node BMC, see “Determining the IP Address of the BaseIO BMC”.

    4. The BMC login screen appears, as shown in Figure 3-1. Login as root with the password superuser.

      fs0:\>cd efi
      fs0:\efi>cd SuSE
      fs0:\efi\SuSe>elilo

      Note: This example shows booting SLES11 SP1. Alternatively, you could boot RHEL 6 at the Shell> prompt.


    13. The operating system login screen appears. At the prompt enter init5, as shown in Figure 3-10.

    15. The SUSE Linux Enterprise Server 11 (x86_64) desktop appears, as shown in Figure 3-12.

    Changing Configuration Settings

    From the Configuration tab shown in Figure 3-13, you can access various configuration setting pages. For example, you can configure fixed network settings under the Network Settings page.

    Under the Mouse Mode Settings page, the Absolute setting should be selected for both Linux and Windows operating systems on the host. Older Linux distributions required Relative mouse mode. SGI Altix UV systems use Absolute mouse mode.

    The remainder of the configuration pages are security related and may be of use to you if you connect the BaseIO BMC to your house network rather than the system management node.

    Determining the IP Address of the BaseIO BMC

    This section describes how to determine the IP address of the BaseIO BMC.

    By default, the external Ethernet port on the BaseIO BMC is configured to use DHCP. In the case that it is connected to an SMN, the SMN will serve it an IP address mapped to a known host name.

    Procedure 3-2. Determining the IP address of the BaseIO BMC without an SMN

      To determine the IP address of the BaseIO, perform the following steps:

      1. Login to the CMC, as follows:

        ssh root@hostname-cmc
        SGI Chassis Manager Controller, Firmware Rev. 1.1.11
        
        CMC:r1i1c>  

      2. Run the iodcon command on the CMC to get to the node BMC 'bmc0', as follows:

        CMC:r1i1c> iodcon
        Starting BaseIO BMC debug console on node BMC 'bmc0'
        *** Use CTRL-X to exit this console ***
        
        SGI UV BMC, Firmware Rev. 1.1.11

      3. Log into the console as root, as follows:

        r1i1b0i login: root
        Password: 
        
        SGI UV BMC, Firware Rev. 1.0.0
        
        r1i1b0i> 

      4. Run the ifconfig eth1 command to obtain the inet addr, as follows:

        r1i1b0i> ifconfig eth1
        eth1      Link encap:Ethernet  HWaddr 08:00:69:15:C1:2B
                   inet addr:172.20.255.254  Bcast:172.20.255.255  Mask:255.255.0.0
                   UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
                   RX packets:331167 errors:0 dropped:0 overruns:0 frame:0
                   TX packets:596190 errors:0 dropped:0 overruns:0 carrier:0
                   collisions:0 txqueuelen:1000
                   RX bytes:22075035 (21.0 MiB)  TX bytes:742617052 (708.2 MiB)
                   Interrupt:1

      5. Enter CTRL-X to exit the console.

      6. The output also displays the MAC address as the HWaddr. You can use this information to configure a known MAC to IP address/host name mapping in your DHCP server.

      Procedure 3-3. Determining the IP address of the BaseIO BMC with an SMN

        To determine the IP address of the BaseIO, perform the following steps:

        1. Establish a network connection to the SMN, as follows:

          # ssh -X sysco@uv-system-smn

          The password set out of the factory is sysco.

        2. Perform the following command to find the IP address of the BaseIO BMC, as follows:

          sysco@uv-sys-smn:~/hw> cmclist -a
          # File: /var/lib/dhcp/db/dhcpd.leases
          # UID              IP Address      
          d \001\010\000i\025\300\237 172.21.0.255    

        Accessing the SGI KVM BIOS Setup Utility

        This section describes how to access the SGI KVM BIOS setup utility software residing on the BaseIO blade.

        Procedure 3-4. Accessing the SGI KVM BIOS Setup Utility

          To access the SGI KVM BIOS setup utility software, perform the following steps:

          1. Perform steps one through 11 in Procedure 3-1.

          2. When the Linux Shell> prompt appears enter exit, as shown in Figure 3-14.

            Figure 3-14. KVM JViewer Shell Prompt with exit Command Screen
