Change the Name of the CommServe Computer

Before changing the name of the CommServe computer, follow the steps below:

  1. Perform a Disaster Recover Backup.

    Verify and ensure that the Disaster Recovery Backup completes successfully. Also note down the location of the disaster recovery backup file. (For a more detailed discussion, see Phases of Disaster Recovery Backups.)

  2. Ensure the following:
    • 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.

  3. 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.

The following procedure describes the steps involved in changing the name of the CommServe computer.

  1. From the Tools menu in the CommCell Console, click Control Panel.
  2. Double-click Name Management.
  3. Select the Update CommServe hostname on CommServe and Remote clients option and click Next to continue.
  4. Select the new CommServe name from the Current CommServe Name list.
  5. Select the old CommServe name from the Old CommServe Host Name list and click Finish to continue.

The operation will change the CommServe name and will automatically inform all the MediaAgents/Clients in the CommCell of the new CommServe name. 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 client/MediaAgents using one of the following procedures:

Change the Name of CommServe in a multiple MediaAgents/Clients

The following procedure describes the steps involved in changing the name of the CommServe in a multiple clients/MediaAgent computers.

  1. From the Tools menu in the CommCell Console, click Control Panel.
  2. Double-click Name Management.
  3. Select the Update CommServe for Clients post Migration or Split option and click Next to continue.
  4. Select the new CommServe name from the Current CommServe Name list.
  5. Select the old CommServe name from the Old CommServe Host Name list and click Next to continue.
  6. Select the names of clients in which the CommServe name should be changed from the Available list and use the arrow button to move them to the Selected list and then click Finish.
    It is recommended that you do not select the Update database even if clients are unreachable option.

    If the option is not selected, and the clients are not reachable, you can subsequently re-run this operation for the failed clients.

    If this option is selected , and the clients are not reachable, you must manually update the clients as described in Manually Updating the CommServe or Domain name on Client/MediaAgent Computers.

The CommServe name will be changed in the selected clients.

Change the Name of Client/MediaAgent Computers

The following procedure describes the steps involved in changing the name in a specific Client/MediaAgent computers. On clustered computers, the name change must be performed from the CommCell Console.

  1. Perform the name change on the computer. After changing the name, ensure the following:
    • 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.

  2. Open the CommCell Console.
  3. Right-click the Client/MediaAgent in which the name was changed, and then click Properties.
  4. From the General tab, click Edit.
  5. From the Edit Client Name dialog box, modify the Client Name and the Host Name.
