Resolution

The ability to modify the DNS server IP address after the initial configuration in an EVO:RAIL appliance is not a component of the EVO:RAIL management interface.
To add/modify the DNS server IP address:
  1. Log into the vCenter Server Appliance using SSH as the root user.
  2. Run this command to stop the EVO:RAIL engine:

    /etc/init.d/vmware-marvin stop

  3. Open the /etc/dnsmasq.conf file using a text editor.
  4. Add or modify the server entry with the new DNS address. For example:

    server=new-dns-addr

    Where new-dns-addr is the new DNS address.

    Note
    : If multiple DNS servers need to be specified, each server must be listed on a separate line.

  5. Run this command to restart the EVO:RAIL engine:

    /etc/init.d/vmware-marvin start

Note: EVO:RAIL configures the VMware vCenter Server Appliance DNS address to 127.0.0.1. Do not change this setting to any other value.
