Copy Services

Manage data that is stored on your DS8800 storage system with Copy Services functions such as FlashCopy®, Global Mirror, and Metro Mirror. Managing your data with Copy Services also requires that you create mirroring connectivity, previously referred to as paths for data communication.

Getting started with Copy Services
Before you use the point-in-time copy and remote mirror and copy features of Copy Services, review the guidelines and requirements for managing a Copy Services environment.
Adding a Copy Services 2105 domain to a storage complex
You can set up a Copy Services 2105 domain by using the DS Storage Manager to create Copy Services functions between machine type 2105 and machine types 242x.
FlashCopy
A FlashCopy relationship creates a copy of a source volume on the target volume. This copy is called a point-in-time copy. When you initiate a FlashCopy operation, a FlashCopy relationship is created between a source volume and a target volume. You can use either the DS Storage Manager (GUI) or DS command-line interface (DS CLI) to help you create, monitor, and manage your FlashCopy operations.
Global Mirror
Global Mirror asynchronously copies data from a host to a remote site, and maintains data on a storage unit at the remote site. You can use either the DS Storage Manager or DS Command-line interface (DS CLI) to help you create, monitor, and manage your Global Mirror operations.
Metro Mirror
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. You can use either the DS Storage Manager or the DS Command-line interface (DS CLI) to help you create, monitor, and manage your Metro Mirror operations.
Mirroring connectivity (paths)
Before you can create Metro Mirror and Global Mirror volume pairs, you must create mirroring connectivity, previously referred to as paths. Mirroring connectivity is needed to communicate between the volume pairs and to copy data from the source volume to target volume.
Modifying logical subsystem Copy Services values
You can modify several logical subsystem (LSS) values.
