Metro Mirror

This topic provides information to help you get started and later manage your data using Metro Mirror functions. Metro Mirror is a function for application data recovery, but also for failover to remote sites for disaster recovery, remote migration of data, and off-site backups.

• Creating a Global Copy relationship
  Complete this task to create a Global Copy relationship between a source volume and a target volume.
• Creating a Metro Mirror relationship
  Complete this task to create a Metro Mirror relationship between a source volume and target volume.
• Creating a Metro Mirror volume pair between a 1750 and a 2105
  Complete this task to create a Metro Mirror volume pair using volumes from a 1750 and a 2105.
• Converting Global Copy volume pairs to synchronous
  Complete this task to convert Global Copy volume pairs to synchronous (Metro Mirror volume pairs).
• Deleting a Metro Mirror relationship
  Complete this task to delete a Metro Mirror relationship between the a source and target volume.
• Performing a failback recovery operation
  Complete this task to confirm the volume pairs on which the disaster recovery failback operation will be run. The failback operation copies all modified tracks from a target volume to a source volume.
• 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.
• Resuming a Metro Mirror relationship
  Complete this task to resume a Metro Mirror relationship between a volume pair that has been suspended (or paused).
• Resynchronizing a Metro Mirror volume pair
  Use this process to resynchronize a volume pair in suspended mode.
• Suspending a Metro Mirror relationship
  Complete this task to suspend a Metro Mirror relationship.
• Viewing information about Metro Mirror relationships
  Complete this task to view information about volume pairs in Metro Mirror relationships.
