Table 57 TrueCopy for Mainframe Operations versus PPRC TSO and ICKDSF Commands (continued)

Description

Command

Issued to:

ICKDSF Command

TSO Command

TrueCopy for

Mainframe

Operation

Resynchronizes a TrueCopy
for Mainframe pair (or
TrueCopy for Mainframe
Asynchronous group), and
sets the TrueCopy for
Mainframe initial copy
options and pair options.
TrueCopy for Mainframe
supports the optional
MODE, PACE, and CRIT
parameters.

M-VOL

PPRCOPY ESTPAIR

CESTPAIR (MODE=
RESYNC)

Resume Pair

Supported by TrueCopy for
Mainframe Synchronous.
Command is rejected by
TrueCopy for Mainframe
Asynchronous pairs.
Redirects application I/Os
from the M-VOL to the
R-VOL.

M-VOL and R-VOL

P/DAS SWAP

Supported by TrueCopy for
Mainframe Synchronous.
Command is rejected by
TrueCopy for Mainframe
Asynchronous pairs.

MCU (M-VOL or
simplex)

CGROUP
(FREEZE/RUN)

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.

PPRC TSO command parameter support depends on the CU emulation (3990, 2105, or
2107). PPRC command extensions are supported when running with 2105 or 2107 emulation.

The PPRC TSO and ICKDSF commands have required and optional parameters which are not
described in detail in this document. For further information on using PPRC TSO and PPRCOPY
ICKDSF commands, see IBM publications Advanced Copy Services (SC35-0355), DFSMS
MVS V1 Remote Copy Guide and Reference (SC35-0169)
, ICKDSF R16 Refresh User's Guide
(GC35-0033)
, and other IBM documents on ICKDSF R16 or later.

The PPRC TSO and ICKDSF commands use slightly different command/keyword names to
provide equivalent PPRC functions. For example, the CESTPAIR TSO command is equivalent
to the PPRCOPY ESTPAIR ICKDSF command. This document describes the PPRC TSO commands.
See the IBM PPRC and ICKDSF documentation for complete information on using PPRCOPY
ICKDSF instead of PPRC TSO commands.

When the CESTPATH command is executed, the following processing is performed.

The path that is used before the CESTPATH command is executed but that is not specified
in the CESTPATH command is deleted.

1.

2.

The path that is used before the CESTPATH command is executed and specified again
in the CESTPATH command is maintained.

3.

The path that is not used before the CESTPATH command is executed but that is specified
in the CESTPATH command is added.

If you specify to delete all paths that are used before the CESTPATH command is executed,
the pair operation might be suspended because the path does not exist temporarily in the
processing described above.
