A Pair operations using PPRC
XP7 supports IBM Peer to Peer Remote Copy (PPRC) TSO and ICKDSF commands for performing
Continuous Access Synchronous 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 remote paths between the main and target systems
•
Add and delete pairs
•
Split and resume pairs.
•
Display pair status and other information.
You cannot change options for remote connections, the CU, initial copy priority, or DFW to S-VOL
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.

RWC operation
Establishes remote paths from an MCU to an RCU. The
default RCU options are used. See
“CESTPATH
command” (page 121) for more information.
MCU PPRCOPY
ESTPATH CESTPATH

Add RCU (and
configure ports)
Deletes all active paths between an MCU and an RCU. MCU PPRCOPY
DELPATH CDELPATH

Delete RCU
Displays the status of all paths for the CU specified by
the DEVN parameter. Cnt Ac-S Z supports the optional MCU PPRCOPY
QUERY/PATHS CQUERY/
PATHS RCU Status
FORMAT/UNFORMAT and VOLUME/PATHS
parameters.
Creates a pair and sets the initial copy and pair options
(copy mode = synchronous only, priority = 0, CFW P-VOL PPRCOPY
ESTPAIR CESTPAIR(MODE=
COPY) Add Pair
data = Primary Volume Only, DFW to Secondary
Volume = not required). Cnt Ac-S Z supports the
optional MODE, PACE, and CRIT parameters. The
MSGREQ parameter defaults to NO.
Splits a pair. Cnt Ac-S Z supports the optional PRIMARY
parameter. See WARNING about the QUIESCE
parameter at the end of this topic. P-VOL or
S-VOL PPRCOPY
SUSPEND CSUSPEND Suspend Pair
Releases a pair from the MCU. P-VOL PPRCOPY
DELPAIR CDELPAIR Delete Pair (to MCU)
Releases a pair from the RCU. S-VOL PPRCOPY
RECOVER CRECOVER Delete Pair (to RCU)
Displays pair status of the volume. Cnt Ac-S Z supports
the optional FORMAT/UNFORMAT and
VOLUME/PATHS parameters. P-VOL or
S-VOL PPRCOPY
