When you change the name of the computer where the CommServe resides, you need to notify the CommServe database and client computers about the new computer name because it also affects the CommServe host name. Rename the CommServe computer from the CommCell Console if you want to update the computer name without reinstalling the CommServe software.
During the name change operation, the CommCell updates the CommServe host name and informs all MediaAgents and clients (non-clustered) in the CommCell of the new CommServe hostname. (The CommCell name (top node) in the CommCell Browser remains unchanged because it is used by other entities in the CommCell environment.)
Notes
-
If MediaAgents or clients are unavailable or offline during the name change operation, the system completes the name change operation when the clients are available.
-
On the computer hosting the Web Server, update the value of the sINSTANCE additional setting to reflect the new CommServe name. This additional setting contains the SQL database instance name in which CommServe database is stored.
-
For information on changing the CommServe host name, see Changing the CommServe Host Name on a Client or Changing the CommServe Host Name on Commserve and Remote Clients Using the Command Line Interface.
Before You Begin
Before changing the name of the CommServe computer, follow the steps below:
-
Perform a Disaster Recover Backup.
Verify that the Disaster Recovery Backup completes successfully. Also note down the location of the disaster recovery backup file.
-
Specify the current CommServe name in the hosts file located in the C:\Windows\System32\drivers\etc directory. The CommServe name should be specified in the following format:
172.xx.xx.xx commservName commservComputer.mydomain.company.com
Adding the CommServe name to the hosts file will allow the upcoming name change operation to automatically update the system DSN with the new CommServe name.
-
Important: Verify that all MediaAgents and clients will be accessible during the CommServe name change process.
-
If you have a firewall, review the information in Network Considerations for Name Change Operations.
Procedure
-
Perform the name change on the computer's operating system and then verify the following:
-
Verify that the computer is available in the network with the new name. (DNS lookup or other name resolution facilities are appropriately configured to resolve the new name of the computer.)
-
Verify that all applications running on the computer, for example, SQL server, Exchange, Server, and Oracle database, function with the new name. To rename a computer that hosts a stand-alone instance of SQL Server, see http://msdn.microsoft.com/en-us/library/ms143799.aspx.
-
Use ping (or other network connectivity utilities) to verify that the computer with the new name is accessible. Also verify that other computers in the network are accessible to the computer with the new name.
-
-
From the CommCell Console ribbon, click the Home tab and then click Control Panel.
-
Under Maintenance, click Name Management.
The Name Management Wizard appears.
-
Select Update CommServe hostname on CommServe and Remote clients and then click Next.
The current hostname of the CommServe is automatically populated in the Old CommServe Name box.
-
In the New CommServe Name box, enter the new host name and then click Finish.
