Assigning the Host Name or IP Address to the Server

In this task you assign the Host Name/IP address to the 5.1(1) server. In 4.x releases, the Host Name/IP Address field (also known as Servername) on the publisher server Server Configuration Settings window contains one of the following types of values:

If DNS is enabled, it identifies the host name.

If DNS is not enabled, it contains the IP address of the server.

To access Server Configuration Settings, navigate to System > Server.

The Data Migration Assistant (DMA) file that is used to migrate data from 4.x to 5.1(1) releases includes the Host Name/IP Address value. When you migrate data by using DMA, the Host Name/IP Address (Servername) for the publisher server gets imported into the 5.1(1) database as follows:

If the Host Name/IP Address (Servername) was a Host Name, the installation program compares this Servername to the provisioned Hostname for the 5.1(1) server (either through static provisioning or DNS/DHCP). If a mismatch exists, the installation program does the following actions:

Uses the provisioned Hostname as the Host Name/IP address for the 5.x server, overriding the servername in the DMA file.

Notifies you about the mismatch and its resolution.

Prompts you to proceed or cancel the installation.

If the Host Name/IP Address (Servername) was an IP address, the installation program compares this Servername to the provisioned IP Address for the 5.x server (either through static provisioning or DNS/DHCP). If a mismatch exists, the installation program does the following actions:

Uses the provisioned IP Address as the Servername for the 5.x server, overriding the servername in the DMA file.

Notifies you about the mismatch and its resolution.

Prompts you to proceed or cancel the installation.

This feature allows you to import your 4.x data to a 5.1(1) server without having to preserve the IP Address or Host Name. The IP Address and/or Host name of the 5.1(1) server can differ from the 4.x servername.


Caution Do not assign a hostname or IP address to the upgraded server that is already assigned to another node in the cluster. Doing so causes the cluster upgrade to fail.
