When you activate the secondary System Manager server, the system stops replicating the data from the primary System Manager server to the secondary System Manager server. During activation, you cannot gain access to the web console of the secondary System Manager server for some time.
In the same browser instance, do not open the primary and secondary System Manager server in different tabs. The system might display an unknown error after the activation, deactivation, or recovery is complete. You can ignore this error message.
Before you begin
Log on to the System Manager web console of the secondary server.
Procedure
On the System Manager web console, click Services > Geographic Redundancy > GR Health.
Click Activate Secondary Server.
The system displays the Geographic Redundancy (GR) Health Current status dialog box.
In the Select the reason for activation, choose one of the following options:
Primary Down: When the primary System Manager server becomes nonoperational, the server hardware is faulty and unusable, or the application server fails to recover.
Network Split: When the enterprise network splits and servers fail to communicate with each other.
Maintenance: When the maintenance activities such as backup, restore, upgrade, and shutdown are in progress.
Other: Any other reason where the primary System Manager server becomes unusable and needs the secondary System Manager server to become operational.
Click Yes.
The system displays the initialization of the activation process.
Click Yes.
The activation process takes about 15–20 minutes to complete.
If the activation process fails, the system displays an error message on the secondary System Manager web console and rolls back to the previous state. If the activation process is successful, the secondary System Manager server changes to the active mode and provides complete System Manager functionality.
Because the server becomes unavailable, you cannot gain access to the web console. Wait until the process is complete before you continue with the next step.
