A Using PPRC commands for Continuous Access
Synchronous Z
This appendix describes how to use PPRC commands to perform Continuous Access Synchronous
Z operations.

Overview of PPRC commands

The P9500 supports IBM Peer to Peer Remote Copy (PPRC) TSO and ICKDSF commands to enable
you to perform Continuous Access Synchronous Z operations from the zSeries and S/390 host
system. PPRC TSO commands are issued from the system console to the M-VOL or R-VOL of a
Continuous Access Synchronous Z pair. PPRCOPY ICKDSF commands are issued from JCL job
cards. The Continuous Access Synchronous Z feature must be installed on the P9500, and IBM
PPRC must be installed on the host operating system.
You cannot change the RCU options, initial copy priority, or the DFW to R-VOL pair options using
PPRC commands.
Port configuration (RCU target <-> initiator) is supported using the CESTPATH and CDELPATH TSO
commands only when system option mode 1 14 ON (see
mode 1 14 is OFF, you must configure the ports using the licensed Continuous Access Synchronous
Z software on the Remote Web Console computer before adding paths and after deleting paths.
Even if you set ON for system option mode 1 14, initiator ports will not automatically change to
RCU target ports, nor vice versa, when these ports are in initiator/external mix mode.

— If system option mode 1 14 is OFF, the ports
must be configured using the Continuous
Access Synchronous Z. If system option mode
1 14 is ON, the ports are configured
automatically (RCU target/initiator to
initiator/RCU target) in response to the
CESTPATH and CDELPATH TSO commands.
However, even if you set ON for system option
mode 1 14, initiator ports will not automatically
change to RCU target ports, or vice versa,
when these ports are in initiator/external mix
mode.
For Fibre Channel interface, do not use the
CESTPATH and CDELPATH commands at the
same time as the SCSI path definition function
of LUN Manager. The Fibre Channel interface
ports need to be configured as initiator ports
or RCU target ports before the CESTPATH and
CDELPATH commands are issued.
MCU Establishes logical paths from an MCU to an
RCU. The default RCU options are used.
M-VOL Deletes all active paths between an MCU and
an RCU.
