The computer name is a name that your computer uses to identify itself in a network or a domain. In a centralized management environment, an Arcserve domain can consist of a primary server and one or more member servers, or a stand-alone server. You establish the names of the Arcserve domain, the computer name of the primary server, and the computer names of the member servers when you install Arcserve Backup.
Arcserve Backup uses the computer names of the primary server and the member servers to establish communication between the servers. Arcserve Backup specifies the computer name of the primary server in the Discovery.cfg configuration file. The Discovery.cfg configuration file resides on the primary server and the member servers.
Note: The Arcserve domain name and the computer name of the primary server can be different. However, both names must not exceed 15 bytes. A name totaling 15 bytes equates to approximately 7 to 15 characters.
When you change the computer name of the primary server or the member servers, the servers cannot communicate with each other in the Arcserve domain.
In an Arcserve domain, the following scenarios exist when you change the computer name of an Arcserve server:
To ensure that the primary server and the member servers can communicate, see Change the Computer Name of the Primary Server on the Primary Server, and Change the Computer Name of the Primary Server on a Member Server.
To ensure that the member server can communicate in the Arcserve domain, see Change the Computer Name on a Member Server.
To ensure that a stand-alone server can communicate in an Arcserve domain, see Change the Computer Name on a Stand-alone Server.
To ensure that a server that is running the Manager Console can communicate in an Arcserve domain, see Change the Computer Name on a Server that is Running the Manager Console.
