Configuring the RLM

You can use the setup command or the rlm setup command to configure the RLM. You can configure the RLM to use either a static or a DHCP address.

Before you begin

AutoSupport should be configured before you configure the RLM. Data ONTAP automatically sends the AutoSupport configuration to the RLM, allowing the RLM to send alerts and notifications through AutoSupport messages.

About this task

If you are running RLM firmware version 4.0 or later, and you have enabled IPv6 for Data ONTAP, you have the option to configure the RLM for only IPv4, for only IPv6, or for both IPv4 and IPv6. Disabling IPv6 on Data ONTAP also disables IPv6 on the RLM.
Attention: If you disable both IPv4 and IPv6, and if DHCP is also not configured, the RLM has no network connectivity.

Steps

  1. At the storage system prompt, enter one of the following commands:
    • setup
    • rlm setup

    If you enter setup, the rlm setup script starts automatically after the setup command runs.

  2. When the RLM setup asks you whether to configure the RLM, enter y.
  3. Do one of the following when the RLM setup asks you whether to enable DHCP on the RLM.
    • To use DHCP addressing, enter y.
    • To use static addressing, enter n.

    Note: DHCPv6 servers are not currently supported.

  4. If you do not enable DHCP for the RLM, the RLM setup prompts you for static IP information. Provide the following information when prompted:

    • The IP address for the RLM
      Note: Entering 0.0.0.0 for the static IP address disables IPv4 for the RLM.
    • The netmask for the RLM
    • The IP address for the RLM gateway
    • The name or IP address of the mail host to use for AutoSupport

  5. If you enabled IPv6 for Data ONTAP and your RLM firmware version is 4.0 or later, the RLM supports IPv6, and the RLM setup asks you whether to configure IPv6 connections for the RLM:
    • To configure IPv6 connections for the RLM, enter y.
    • To disable IPv6 connections for the RLM, enter n.

    Note: You can use the rlm status command to find the RLM version information.

  6. If you choose to configure IPv6 for the RLM, provide the following IPv6 information when prompted by the RLM setup:

    • The IPv6 global address

      Even if no IPv6 global address is assigned for the RLM, the link-local address is present on the RLM. The IPv6 router-advertised address is also present if the ip.v6.ra_enable option is set to on.

    • The subnet prefix for the RLM
    • The IPv6 gateway for the RLM

    Note: You cannot use the RLM setup to enable or disable the IPv6 router-advertised address for the RLM. However, when you use the ip.v6.ra_enable option to enable or disable the IPv6 router-advertised address for Data ONTAP, the same configuration applies to the RLM.

    For information about enabling IPv6 for Data ONTAP or information about global, link-local, and router-advertised addresses, see the Data ONTAP Network Management Guide for 7-Mode.

  7. At the storage system prompt, enter the following command to verify that the RLM network configuration is correct:
    rlm status
  8. At the storage system prompt, enter the following command to verify that the RLM AutoSupport function is working properly:
    rlm test autosupport

    Note: The RLM uses the same mail host information that Data ONTAP uses for AutoSupport.

    The following message is a sample of the output Data ONTAP displays:

    Sending email messages via SMTP server at mailhost@companyname.com. If autosupport.enable is on, then each email address in autosupport.to should receive the test message shortly.

Examples for configuring the RLM and displaying the configuration information

The following example shows that the RLM is configured for both IPv4 and IPv6 connections:
toaster> rlm setup
	  The Remote LAN Module (RLM) provides remote management capabilities
 	 including console redirection, logging and power control.
 	 It also extends autosupport by sending
 	 additional system event alerts. Your autosupport settings are used
 	 for sending these alerts via email over the RLM LAN interface.
