To change some of the information that you supplied when you installed Site Recovery Manager Server, you can run the Site Recovery Manager installer in modify mode.

Installing Site Recovery Manager Server binds the installation to a number of values that you supply, including the vCenter Server instance to extend, the Site Recovery Manager database type, DSN and credentials, the certificate, and so on. The Site Recovery Manager installer provides a modify mode that allows you to change some of the values that you configured when you installed Site Recovery Manager Server:

  • The Platform Services Controller address, if the vCenter Server instance that Site Recovery Manager extends moves to a different Platform Services Controller
  • The vCenter Single Sign-On user name and password, if they changed since you installed Site Recovery Manager
  • The information with which you register Site Recovery Manager with vCenter Server
  • Upload or generate a new certificate
  • The user name, password, and connection numbers for the Site Recovery Manager database
  • The user account under which the Site Recovery Manager Server service runs
Note: If you change the certificate that vCenter Server or Platform Services Controller uses, you must run the Site Recovery Manager installer in modify mode. Running the Site Recovery Manager installer in modify mode updates the Site Recovery Manager certificate thumbprints to reflect the new vCenter Server or Platform Services Controller certificate.

Prerequisites

Verify that you have administrator privileges on Site Recovery Manager Server or that you are a member of the Administrators group. Disable Windows User Account Control (UAC) before you attempt the change operation or select Run as administrator when you start the Site Recovery Manager installer.

Procedure

  1. Log in to the Site Recovery Manager Server host.
  2. Open Programs and Features from the Windows Control Panel.
  3. Select the entry for VMware vCenter Site Recovery Manager and click Change.
  4. Click Next.
  5. Select Modify and click Next.
  6. Verify or modify the information with which to register the Site Recovery Manager extension with Platform Services Controller, and click Next.
    Option Description
    Address You can change the Platform Services Controller address if vCenter Server migrated to a different Platform Services Controller after the initial installation of Site Recovery Manager.
    Important: If you change the Platform Services Controller address, you must reconfigure the connection between the Site Recovery Manager sites after you have updated the installation.
    HTTPS Port Change the Platform Services Controller port if it changed after the initial installation of Site Recovery Manager.
    Username Modify the vCenter Single Sign-On user name, if it has changed since the initial installation.
    Password Enter the vCenter Single Sign-On password.
  7. If prompted, verify the Platform Services Controller certificate and click Accept to accept it.
  8. Verify the vCenter Server instance that Site Recovery Manager extends, and click Next.
    You cannot use the installer's modify mode to change the vCenter Server instance that Site Recovery Manager extends.
  9. Verify or modify the information with which to register the Site Recovery Manager extension with vCenter Server, and click Next.
    Option Description
    Administrator E-mail Modify this value if the Site Recovery Manager administrator has changed after you installed Site Recovery Manager Server.
    Local Host The address of the host on which Site Recovery Manager Server runs. If you change this value, you must either regenerate the certificate or provide a new certificate that includes the new address in Step 10.
    Important: To facilitate IP address changes in your infrastructure, provide a fully qualified domain name (FQDN) whenever possible, rather than an IP address.
    Listener Port The port for all HTTPS traffic between Site Recovery Manager Server and vCenter Server. The default port is 9086.
    Note: Changing the listener port prevents you from using the VMware Site Recovery service on VMware Cloud on AWS.
    SRM UI Port The HTTPS port for the Site Recovery Manager user interface.
  10. Select a certificate type and click Next.
    Option Description
    Automatically generate a certificate Select this option to generate a new auto-generated certificate.
    Use a PKCS #12 certificate file Select this option to upload a new custom certificate.
    Use existing certificate Select this option to retain the current certificate. If the installed certificate is not valid, this option is unavailable.
    If you do not select Use existing certificate, you are prompted to supply additional details such as the certificate location or strings to use for Organization and Organizational Unit.
    Important: If you modified the Local Host value for Site Recovery Manager Server in Step 9, you must select Automatically generate a certificate to regenerate the certificate or Use a PKCS #12 certificate file to upload a certificate that includes the new Site Recovery Manager Server address. If you select Use existing certificate, the installation modification succeeds, but attempts to log in to Site Recovery Manager fail because the certificate contains an incorrect address for the Site Recovery Manager Server host.
  11. Verify or modify the database configuration information and click Next.
    If you selected the embedded database when you installed Site Recovery Manager, you cannot modify the installation to use an external database, or the reverse.
    Option Description
    Data Source Name The DSN for the Site Recovery Manager database. This only appears if you use the embedded database. You cannot change this value.
    Database User Name A user ID valid for the specified database. Modify this value if the database user account has changed after you installed Site Recovery Manager Server.
    Database Password The password for the specified user ID. Modify this value if the password for the database user account has changed after you installed Site Recovery Manager Server. You must enter this value in all cases.
    Database Port This only appears if you use the embedded database. You cannot change this value.
    Connection Count Modify the initial connection pool size. If all connections are in use and a new one is needed, a connection is created as long as it does not exceed the maximum number of connections allowed. It is faster for Site Recovery Manager to use a connection from the pool than to create one. The maximum value that you can set depends on your database configuration. In most cases, it is not necessary to change this setting. Before changing this setting, consult with your database administrator. Setting the value too high can lead to database errors.
    Max Connections Modify the maximum number of database connections that can be open simultaneously. The maximum value that you can set depends on your database configuration. If the database administrator restricted the number of connections that the database can have open, this value cannot exceed that number. In most cases, it is not necessary to change this setting. Before you change this setting, consult with your database administrator. Setting the value too high can lead to database errors.
  12. Select or deselect the Use Local System account check box to change the user account under which the Site Recovery Manager Server service runs, and click Next.
    • If you deselect Use Local System account, you must provide a username and password for a valid user account.
    • If you are using SQL Server with Integrated Windows Authentication, the username text box shows the username of the account that is running the installer and cannot be modified.
  13. Click Install to modify the installation.
    The installer makes the requested modifications and restarts the Site Recovery Manager Server.

What to do next

When the modification operation is finished and the Site Recovery Manager Server restarts, log in to the vSphere Web Client to check the connection between the sites. If the connection is broken, or if you changed the Platform Services Controller address, reconfigure the site pairing. For instructions about how to reconfigure the site pairing, see Reconfigure the Connection Between Sites.
