Configuring Lenovo Flex System chassis components by using the CLI

You must configure the Lenovo Flex System chassis and its components for your operating environment. You can perform this configuration by using the CMM command-line interface.

The Lenovo Flex System chassis automatically detects the modules and compute nodes that are installed and stores the vital product data (VPD). When the chassis is started, the CMM automatically configures the remote management and console (Ethernet) connector of the CMM, so that you can configure and manage Lenovo Flex System components. You configure and manage Lenovo Flex System components remotely by using the CMM command-line interface (CLI) or the CMM web interface. The CMM web interface includes an initial setup wizard that simplifies the setup operation (see Using the Initial Setup Wizard for information). The optional Lenovo XClarity Administrator or Flex System Manager software also supports selected configuration and management functions for the Lenovo Flex System chassis.

To manually configure the basic settings for an Lenovo Flex System chassis by using the CMM CLI, complete the following steps:

  1. Configure the CMM to use the CLI (see Configuring the CMM for CLI operation for information).
  2. Start a CMM CLI session (see Starting the command-line interface for information).
  3. View the installed components in the Lenovo Flex System chassis and their health status by using the list command (see list command for information) and health command (see health command for information). All components in the chassis should be shown and indicate a healthy state.
  4. Verify that the general settings of the CMM are correct by using the config command (see config command for information).
  5. Set the system date and time by using the date command (see date command for information).
  6. Verify the CMM IP configuration by using the ifconfig command (see ifconfig command for information).
  7. Set up credentials of the main supervisor user account (USERID) by using the users command (see users command for information).
  8. To communicate with network resources and with components in the Lenovo Flex System chassis, configure the I/O-module ports.
    • To communicate with the compute nodes for functions such as deploying an operating system or application program over a network, at least one external (in-band) port on an Ethernet switch in one of the I/O bays of the Lenovo Flex System chassis must be configured for operation and connected.
    • If a pass-thru module is installed in an I/O bay (instead of an Ethernet I/O module), you might have to configure the network switch that the pass-thru module is connected to; see the documentation that comes with the pass-thru module and the network switch for information and instructions.
    • You might be able to configure an I/O module through its external management connector. An Ethernet switch module can be configured through an external port that is enabled for management connection by the CMM. Depending on your I/O module and configuration, configuration can be performed by using a Telnet interface, a serial connection, or a web browser. See the documentation that comes with each I/O module for information and instructions.
    1. Enable and configure I/O-module port settings by using the ports command (see ports command for information).
    2. Configure IP addresses for the I/O modules by using the ifconfig command (see ifconfig command for information).
  9. Set the overall CMM security policy by using the security command (see security command for information).
  10. Set the CMM DNS configuration by using the dns command (see dns command for information).
  11. Set an email address for CMM event notifications by using the alertentries command (see alertentries command for information).
These steps complete basic configuration of the Lenovo Flex System chassis. You can now perform additional setup operations, as required, for your specific chassis configuration.
