Configuring Host Name Settings

Use the General page to configure the Host Name and Domain Name. The host name and the domain name together constitute the fully qualified domain name.

Prerequisites

Role: Administrator with chassis access

Procedure
  1. Click Management Network in the navigation tree, and then click the General tab.
  2. Enter the Subsystem Name (Host name).
    The host name is the DNS name of the Moonshot CM 2.0 subsystem. This name can be used only if DHCP and DNS are configured to connect to the Moonshot CM 2.0 subsystem name instead of the IP address.
  3. Enter the Domain Name if DHCP is not configured.
  4. Click Apply.
    NOTE: If DHCP is configured, the specified value is added under Search Domains and the domain value used is the one routed from the DHCP server. If DHCP is not configured, the specified value is considered as the domain.

Host name and domain name limitations

When reconfiguring the Host Name Settings, note the following:

  • Name service limitations—The subsystem name is used as part of the DNS name.

    • DNS allows alphanumeric characters and hyphens.

    • Always start the hostname with a letter, and not with a number or a hyphen. Any combination of letters, numbers, and the hyphen can be used after the first letter.

    • Name service limitations also apply to the Domain Name.

  • Namespace issues—To avoid these issues:

    • Do not use the underscore character.

    • Limit subsystem names to 15 characters.

    • Verify that you can ping the Moonshot CM 2.0 processor by IP address and by DNS name.

    • Verify that NSLOOKUP resolves the Moonshot CM 2.0 network address correctly and that no namespace conflicts exist.

    • Flush the DNS name if you make any namespace changes.
