Restoring Services If the Production Site Fails

Scenarios

If the production site servers and disks fail due to physical faults, you can fail over services to the DR site servers and disks to guarantee service continuity.

DR site servers and disks can be used immediately after a failover. You can power on the servers, or use CBR to restore data to a specified data restore point.

After a failover is started, data synchronization stops.
After the failover is complete, the status of the protection group changes to Failover complete. Go to the protected instance details page and start the DR site server.

Notes and Constraints

For Linux servers with Cloud-Init installed, if you have changed hostname of the production site server before you perform a failover for the first time, this modification will not synchronize to the DR site server.
To resolve this problem, see What Can I Do If hostname of the Production Site Server and DR Site Server Are Different After a Planned Failover or Failover?

The protection group must contain replication pairs.
Protection is enabled for the protection group, and the protection group is in the Protecting, Failover failed, or Planned failover failed state.

Procedure

Log in to the console.
Click Service List and choose Storage > Business Recovery Service.

The Business Recovery Service page is displayed.
In the pane of the desired protection group, click Protected Instances.

The protection group details page is displayed.
In the upper right corner of the page, click More and choose Fail Over from the drop-down list.

The Fail Over dialog box is displayed.
Click Fail Over.

During the failover, do not start or stop the servers in the protection group. Or, the failover may fail.
