Paths

Before you can create Metro Mirror and Global Mirror volume paths, you must create paths. Paths are needed to communicate between the volume pairs and to copy data from the source volume to target volume.

The Paths feature is accessible only from the Real-time Manager; the Paths feature is not accessible from the Simulated Manager.

• Paths — Main page
  Use this page to work with paths for remote mirror and copy relationships. The paths are needed to communicate between a source LSS in a storage unit and a target LSS in another storage unit and to copy data from the source to the target volumes.
• Create paths — Select source LSS
  Use this page to select a source logical subsystem (LSS) to which to create a logical path between the source LSS that you select and a target LSS.
• Create paths — Select target LSS
  Use this page to select a target logical subsystem (LSS) to which a logical path will be created between the target LSS that you selected and the source LSS.
• Create paths — Select source I/O ports
  Use this page to select I/O port properties for the source LSS. You can use one or more port properties.
• Create paths — Select target I/O ports
  Use this page to select I/O port properties for the target LSS.
• Create paths — Select path option
  Use this page to define a consistency group for all volume pairs using this path. Consistency groups are used for controlling error situation and for maintaining data consistency across volume pairs sharing this path.
• Create paths — Verification
  Use this page to verify the options that you selected for the paths that will be created.
• LSS copy options
  Use this page to define copy options for logical subsystems (LSSs). The LSS copy options that you select here are applied to all the volumes of an LSS when Remote Mirror and Copy requests are processed.
