Performing a failover recovery operation

Complete this task to confirm the volume pairs on which the disaster recovery failover operation will be run. In a disaster recovery process, the failover procedure must be followed by a failback procedure after a path from the target site to the source site is created.

You must have created a remote mirror and copy volume pair. Volume sizes for operations that use failover and failback operations must be the same; otherwise, the failback operation fails.

When you are ready to return to Site A (your production site), issue the failback operation (on the Volume A-Volume B pair) from Site B (your recovery site). This process makes the target volume (Volume B) transition to a source and the original source volume (Volume A) transition to a new target volume. The process will re-synchronize the volumes with those at Site A. At Site A, ensure failback process is complete and that the volume pair is duplex.

Perform the following steps to confirm the volume pairs on which the disaster recovery failover operation will be run:

  1. In the navigation, select Real-time Manager > Copy Services > Metro Mirror. A page containing a list of Metro Mirror volumes displays. Select one or more volumes on which to perform an action.
  2. Select Recovery Failover from the Select Action drop-down box and click OK.
  3. A table displays showing the volume pairs in which the failover process will occur. Volume nicknames are not displayed if the volumes are associated with a 2105.
  4. If you want to cancel the options, click Cancel and the page closes.
