Configuring the FQDN template of profile servers

The information from the article applies only when the Working with the Server profiles module is connected.

The “Server Profiles” module allows you to set a fully qualified domain name for each profile server according to a single template. A fully qualified domain name (FQDN) is a domain name that includes the names of all parent domains. In the fully qualified domain name template, you can use the parameters:

server ID: {server_id};
server name: {server_name};
rack name: {rack_name};
unit number: {unit}.

Profile servers can have third-level or higher domain names. For example:

server-1.example.com — third-level domain name;
server-1.rack-4.dci6.example.com — fifth-level domain name.

Applying FQDN templates

To apply the FQDN name template to profile servers:

From the left menu, click Servers → Profiles.
Select the desired profile or create a new one.
Go to Network Settings.
Activate the Hostname (FQDN) switch and enter the domain name template in the input field. You can click on the All Available Macros drop-down list and click to add the parameters you want to the template.
Click Save without applying to servers or Save and apply to servers.

Example of a domain name template using all parameters:

{server_name}-{server_id}.{rack_name}.{unit}.example.com

Syntax

Only the characters a-Z, 0-9, “-” and “.” are allowed in the fully qualified domain name. Space and underscores are automatically replaced by the “-” character. This restriction applies also to parameter values that are used in the template. For example, if the {server_name} parameter is used in the template, then the names of all profile servers must consist only of supported characters.

If other characters are present, the template cannot be applied and the operation will end with an error.

The FQDN format implies termination with a dot, e.g.: “dci6.example.com.”. In the FQDN template in DCImanager 6, you do not need to put a dot at the end.
