Setting up your environment to use PPRC extended distance

There are three requirements for setting up your environment to use PPRC extended distance mode:

• A PPRC link must be active between the primary logical subsystem or storage control and recovery logical subsystem or storage control.
• A PPRC volume pair must be established with the CESTPAIR OPTION(XD) command.
• The primary and secondary devices must be in SIMPLEX state or in SUSPEND state at the beginning of the process.

For additional information about:

• Establishing PPRC links, refer to Ensuring PPRC paths are active.
• PPRC volume pairs, refer to Establishing PPRC volume pairs.
• Implementing PPRC extended distance, refer to Scenarios using PPRC extended distance and synchronous mode for backup purposes.
