PPRCOPY commands—CKD

Peer-to-Peer Remote Copy (PPRCOPY), also referred to as PPRC, allows synchronous and asynchronous copying of a DASD volume from one subsystem to another subsystem volume, without host system dependencies, for those subsystems that support it.

A detailed description of PPRCOPY can be found in z/OS DFSMS Advanced Copy Services. You need to read this before using the ICKDSF PPRCOPY commands.

This topic provides information on PPRCOPY and on the ICKDSF PPRCOPY commands, which initiates and supports the PPRCOPY functions:

How PPRCOPY works
Using synchronous and asynchronous PPRCOPY; see Asynchronous PPRCOPY for additional information on Asynchronous PPRCOPY.

PPRCOPY commands
Attention: In the following commands, PPRCOPY is shown as the keyword before each command, you can use PPRC in place of PPRCOPY.

PPRCOPY DEFINESESSION

–Sessions are OPENed (created) and CLOSEd (terminated); see PPRCOPY DEFINESESSION.

PPRCOPY DELPAIR

–Deletes remote copy device pairs; see PPRCOPY DELPAIR–deleting pairs.

PPRCOPY DELPATH

–Deletes ESCON and FCP paths between two subsystems; see PPRCOPY DELPATH–deleting paths.

PPRCOPY ESTPAIR

–Establishes remote copy device pairs; see PPRCOPY ESTPAIR–establishing pairs.

PPRCOPY ESTPATH

–Establishes ESCON and fibre channel protocol (FCP) paths between two subsystems; see PPRCOPY ESTPATH–establishing paths.

PPRCOPY FREEZE

–Suspends all operations for all PPRCOPY volumes on a single storage control; see PPRCOPY FREEZE–suspend all operations for all PPRCOPY volumes on a single storage control.

PPRCOPY POPULATESESSION

–Populates or depopulates a previously OPENed session with volumes; see PPRCOPY POPULATESESSION.

PPRCOPY QUERY

–Queries status; see PPRCOPY QUERY–querying status.

PPRCOPY QUERY ASYNCCOPY

–Queries data about the Asynchronous PPRCOPY configuration; see PPRCOPY QUERY ASYNCCOPY.

PPRCOPY QUERY OUTOFSYNCSTATE

–Queries data about the number of volumes in the specified session that are out of sync; see PPRCOPY QUERY OUTOFSYNCSTATE.

PPRCOPY QUERY SESSIONSDEVICES

–Queries status of the session open on the LSS; see PPRCOPY QUERY SESSIONSDEVICES.

PPRCOPY RECOVER

–Reestablishes access to a secondary volume; see PPRCOPY RECOVER–recovering data on the recovery system.

PPRCOPY RUN

–Resumes all operations for all PPRCOPY volumes on a single storage control; see PPRCOPY RUN–resume all operations for all PPRCOPY volumes on a single storage control.

PPRCOPY SETCHARACTERISTICS

-Allows management software to designate a Metro Mirror pair in a Multi-Target Mirror configuration that must remain full duplex when performing a Remote Pair FlashCopy® (Preserve Mirror) operation.

PPRCOPY STARTASYNCCOPY

–Initializes or modifies and starts the configuration of an Asynchronous PPRCOPY session; see PPRCOPY STARTASYNCCOPY.

PPRCOPY SUSPEND

–Suspends pairs; see PPRCOPY SUSPEND–suspending pairs.

PPRCOPY TERMASYNCCOPY

–Pauses or terminates Asynchronous PPRCOPY for the specified session; see PPRCOPY TERMASYNCCOPY.
