Applies To: System Center 2012 R2 Operations Manager, System Center 2012 - Operations Manager, System Center 2012 SP1 - Operations Manager

Use the following procedure to remove the management server role from a computer. For example, you might have to do this if you have to reassign a computer that is hosting the management server role and install a gateway server.

Before you remove the management server role from a computer, you must configure any objects that are managed by that management server, to be managed by a different management server as described in the following sections.

The high-level steps to remove a management server role are as follows:

  1. Delete the Management Server from the management group.

  2. If the management server you are about to remove functions as a primary management server for an agent, you must configure those agents to use a new primary management server. See Change the Primary Management Server.

  3. If the management server you are about to remove acts as a proxy agent for an agentless-managed computer, you must identify a new management server. See Configure an Agentless-Managed Computer to Use a Different Proxy Agent.

  4. If the management server you are about to remove acts as a proxy agent for a network device, you must identify a new management server. See Configure a Network Device to Use a Different Operations Manager 2012 Proxy Agent.

  5. Remove the management server role from a computer. See Remove the Management Server from a Computer.

Delete the Management Server

Use the following procedure to delete a management server role from the management group.

To delete a management server from the management group

  1. Open the Operations console with an account that is a member of the Operations Manager Administrator role for the management group.

  2. In the Operations console, click the Administration button.

    Note

    When you run the Operations console on a computer that is not a management server, the Connect To Server dialog box appears. In the Server name box, type the name of the Operations Manager management server that you want the Operations console to connect to.

  3. In the Administration pane, click Management Servers.

  4. Right-click the desired management server, and then click Delete.

  5. In the Confirm Delete Management Server dialog box, click Yes.

Change the Primary Management Server

Use the following procedure to change the primary management server for agent-managed computers that are assigned to primary and secondary management servers without using Active Directory Domain Services.

To change the primary management server for agent-managed computers by using the Operations console

  1. Open the Operations console with an account that is a member of the Operations Manager Administrator role for the management group.

  2. In the Operations console, click the Administration button.

    Note

    When you run the Operations console on a computer that is not a management server, the Connect To Server dialog box appears. In the Server name box, type the name of the Operations Manager management server that you want the Operations console to connect to.

  3. In the Administration pane, expand Administration, expand Device Management, and then click Agent Managed.

  4. In the Agent Managed pane, select the computers for which you want to change the primary management server, right-click them, and then select Change Primary Management Server.

    Note

    The Change Primary Management Server option is unavailable if Active Directory Domain Services was used to assign any of the selected computers to the management group.

  5. In the Change Management Server dialog box, select the desired management server in the list, and then click OK. The change takes effect on the agent after its next update interval.

If you are changing the primary management server for a Linux or UNIX computer, the certificate that was used to access the Linux or UNIX computer must also be copied to the new management server. You do not have to copy the certificate if you are changing the primary management server for computers that are running Windows.

To copy a certificate from one server to another server

  1. Log on to the management server that has the certificate that you want to copy.

  2. At the command prompt, change the directory to %ProgramFiles%\System Center 2012 – Operations Manager. Run the following command: scxcertconfig.exe – export <filename>.

  3. While the file created by scxcertconfig.exe contains only the public key of the certificate, you should still treat it as a security-sensitive file. The file, and any copies of the file, should be explicitly deleted when the certificate is imported into the new management server in step 5 in this procedure. Verify that the new management server can access the file copy location.

  4. Log on to the management server that you want to monitor agents from.

  5. At the command prompt, change the directory to %ProgramFiles%\System Center 2012 – Operations Manager. Run the following command: scxcertconfig.exe –import <filename>.

The imported certificate is required for Operations Manager to trust agents signed with that certificate. If multiple management servers are signing certificates, the certificates must be exported from each management server, and imported to the other management servers.

Configure an Agentless-Managed Computer to Use a Different Proxy Agent

Use the following procedure to change the Operations Manager proxy agent for an agentless-managed computer. The proxy agent can be any agent-managed computer in the management group that is configured to be a proxy.

To change the proxy agent for agentless-managed computers

  1. Open the Operations console with an account that is a member of the Operations Manager Administrators role.

  2. In the Operations console, click the Administration button.

    Note

    When you run the Operations console on a computer that is not a management server, the Connect To Server dialog box appears. In the Server name box, type the name of the Operations Manager management server that you want the Operations console to connect to.

  3. In the Administration pane, expand Administration, expand Device Management, and then click Agentless Managed.

  4. In the Agentless Managed pane, select the agentless-managed computers for which you want to change the proxy agent, right-click them, and then select Change Proxy Agent.

  5. In the Change Proxy Agent dialog box, select the computer that you want to be the new proxy agent, and then click OK.

Configure a Network Device to Use a Different Operations Manager 2012 Proxy Agent

Use the following procedure to change the Operations Manager proxy agent for network devices. The proxy agent can be any agent-managed computer in the management group. It must have Simple Network Management Protocol (SNMP) installed, an optional Windows element, and be able to connect to the devices that use SNMP.

To change the proxy agent for network devices

  1. Open the Operations console with an account that is a member of the Operations Manager Administrators role.

  2. In the Operations console, click the Administration button.

    Note

    When you run the Operations console on a computer that is not a management server, the Connect To Server dialog box appears. In the Server name box, type the name of the Operations Manager management server that you want the Operations console to connect to.

  3. In the Administration pane, expand Administration, expand Device Management, and then click Network Devices.

  4. In the Network Devices pane, select the network devices for which you want to change the proxy agent, right-click them, and then select Change Proxy Agent.
