Recovery failover — Confirm

Use this page to confirm which volume pairs to use during a failover operation to your recovery site. This process allows the volumes from your recovery site to be used to restart your production environment during a planned or unplanned outage.

Introduction

A failover operation is used to restart a production environment using the volumes from the recovery site. A failover operation is followed by a failback operation after a path from your recovery site to the production site is created. The failover and failback operations are designed to help reduce the time that is required to synchronize volumes after switching between the source and the target sites.

Use this page to confirm the volume pair in which the target volume at the recovery site will become a source volume and the source volume of the volume pair as the target volume for the new failover operation. A path must be active and the volumes available, otherwise this process fails. The recovery failover is done on the tracks that is associated with the specified storage unit when you click OK.
Note: Volume sizes for operations that use failover and failback must be the same; otherwise, the failback operation fails.
