Specify the Node Naming Series

  • Article

If you will deploy nodes from bare metal, and you are not using a node XML file to import nodes to the cluster, computer names can be automatically generated for the new nodes that are being deployed. You must specify how those names will be generated, by defining a naming series.

The naming series is defined by selecting a root name and the starting number that will accompany that name. The starting number is enclosed in percentage signs (%).

For example, if you deploy three nodes after specifying the following naming series: Node-%100%, those nodes will be assigned these names:

  • Node-100

  • Node-101

  • Node-102

To specify the node naming series

  1. In the Deployment To-do List, click Configure the naming of new nodes. The Specify Node Naming Series dialog box opens.

  2. Type the naming series that you want to use. The preview in the Specify Node Naming Series dialog box helps you to see an example of how the naming series will be applied to the names of the nodes.

  3. To save the node naming series that you have specified, click OK.

Additional considerations

  • Node names are limited to 15 characters. When specifying the node naming series take into account the number of nodes in your deployment and ensure that the series that you specify will not generate names that exceed 15 characters. For example, if your deployment will consist of 1,000 nodes, and your starting number is 1, your root name cannot have more than 12 characters; otherwise, your node number 1,000 will need a name that consists of 16 characters.

  • You cannot specify a node naming series that consists only of numbers.
