Changing DNS or Hosts file settings

Use the following procedures to change the DNS or Hosts file settings after initial configuration.

Changing DNS settings

To change the DNS server IP address or search domain

  1. From the Flex Appliance Shell, run the following command:

    system set-DNS

  2. Follow the prompts to change the DNS settings as follows:

    • To replace the existing settings with new parameters, enter the new information in the appropriate fields. You can enter multiple DNS server IP addresses or search domains using a comma-separated list.

    • To remove the DNS settings, leave the fields blank.

      Warning:

      If you remove existing DNS settings, you must add the hostname resolution information to the appliance Hosts file. See Changing Hosts file settings.

Changing Hosts file settings

If you do not want to use DNS or want to bypass DNS for specific hosts, you can use the appliance Hosts file to manage the hostname resolution information.

To add entries to the Hosts file

  1. Gather the following information for all appliance nodes and for the Flex Appliance Console, if applicable:

    • IP address

    • Hostname

    • Domain

  2. From the Flex Appliance Shell, run the following command:

    system add-host

  3. One at a time, enter the required information for the nodes and the Flex Appliance Console, if applicable.

To remove an entry from the Hosts file

  1. From the Flex Appliance Shell, run the following command:

    system remove-host

  2. Enter the IP address of the host that you want to remove.
