HP XP P9000 Continuous Access Synchronous for Mainframe Systems User Guide

A Pair operations using PPRC
XP P9500 supports IBM Peer to Peer Remote Copy (PPRC) TSO and ICKDSF commands for
performing Cnt Ac-S Z operations from the zSeries and S/390 host system.
PPRC commands and requirements are described in this topic. However, not all instructions for
using the commands are provided. Refer to the IBM user documentation for more information.
Overview of PPRC commands
The following operations can be performed using PPRC issued from JCL job cards:
• Port configuration using Remote Web Console (cannot be done using PPRC).
You can change port type (RCU target to initiator, and so on) as part of the pair creation
operation using CESTPATH.
• Add and remove logical paths between the main and target systems
• Add and delete pairs
• Suspend and resume pairs.
• Display pair status and other information.
You cannot change RCU options, CU options, initial copy priority, or DFW to S-VOL pair options
using PPRC commands.
The following table describes Cnt Ac-S Z operations you perform using Remote Web Console and
the corresponding TSO and ICKDSF commands.

Establishes logical paths from an MCU to an RCU. The
