It may be necessary to change the names of CommServe, MediaAgent and/or Client
computers in a CommCell. The need to change the names of computers may occur in
one or more of the following situations:
When the CommServe is moved or hardware changed to provide for a better
configuration.
When a CommCell is migrated and the clients are moved to another
CommServe.
When the domain name associated with an entire CommCell or part of a CommCell
is changed.
When a Client is moved or hardware changed to provide for a better configuration.
The following sections describes the name management process in all of the above
situations.
Ensure the following before you change the names of computers in the CommCell
using the CommCell Console:
Change the name of the computer in the operating system.
Make sure that the computer is available in the network with the
new name. (DNS lookup or other name resolution facilities is
appropriately configured to resolve the new name of the computer.)
Ensure that all applications running on the computer, such as SQL
server, Exchange, Server, Oracle database, etc function with the new
name. For the procedure 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 such network connectivity
utilities) to verify whether the computer which has a new name, is accessible.
Also ensure that the other computers in the network are accessible to
the computer with the new name.
Name management process is supported for all components from the CommCell
Console.
Computers in Windows and Unix are supported in the clustered environment.
(Netware is not supported in the clustered environment.). When performing the
name change process in a clustered environment, use the CommCell Console to
perform the name change.
Consider the following before performing the name change operation in a CommServe:
All MediaAgents/Clients must be accessible during the CommServe name change
process. If for some reason the MediaAgents/Clients were not accessible a dialog
box will provide a list of MediaAgents/Clients that were unavailable during
the name change operation. In such case, make sure that the MediaAgents/Clients
are accessible and perform the name change operation in those MediaAgents/Clients
using one of the following procedures:
The Client/MediaAgent name can be changed from the Client or MediaAgent Properties
in the CommCell Console. See
Change the
Name of Client/MediaAgent Computers. for step-by-step instructions.
When performing the name change process in a clustered environment, use the
CommCell Console to perform the name change.
The CommServe, MediaAgent and Client names can be changed from the command line.
This maybe useful when you install the software using the
Decoupled Install
and would like to change the name of the computer when the computer is registered.
The command must be executed locally, in the computer,
and cannot be used to change the name of a remote computer.
Use the following steps to change the hostname or display name of a
MediaAgent/Client computer as an example:
Navigate to the <Software Install Directory>\Base folder
and run the following command:
newcomputername is the new display
name of the computer
oldcomputername is the name of the
computer currently displayed in the CommCell Browser
The command will display the "Successfully changed names" message when completed.
You can run the above commands for the CommServe
and Web Server computers by replacing the
CCNAME parameter in the command with
CSNAME for the CommServe, or WEBSERVER
for the Web Server.
Restart the Services from the Service Control Manager, see
Start Services on Windows for
step-by-step instructions.
Once the services are started open the CommCell
Console. The new name for the computer will be displayed in the CommCell
Browser.
If
Application Based Firewall is enabled on computer then the Name Change operation
may fails. Perform the following steps if you encounter this problem:
If the name change operation is performed on a client that contains the File
Archiver for Windows/Unix agent, services must be restarted on that client
after the name change operation. This will ensure that stub recall from
these clients functions correctly.
Web Search Server
When the CommServe name is changed, the value in the
sINSTANCE registry key, in the computer hosting
the Web Search Server, must be changed to reflect the new CommServe name. This
registry key contains the SQL database instance name in which CommServe database
is stored. See sINSTANCE
registry key for more information.
When you change the name of a client that has the Web Search Server installed,
make sure to change the URLs from the
Search Server URLs
tab of the Client Properties dialog box.
