146 TrueCopy for the XP128/XP1024/XP10000/XP12000
XP128/XP1024/XP10000/XP12000 SVP error code. If you need to call HP technical support for
assistance, report the TC390 and SVP error codes.

Using PPRC Commands for TrueCopy
Overview of PPRC Commands
The XP128/XP1024/XP10000/XP12000 supports IBM Peer-to-Peer Remote Copy (PPRC) TSO and
ICKDSF commands to perform TC390 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 TC390 pair. PPRCOPY ICKDSF
commands are issued from JCL job cards. The TC390 feature must be installed on the
XP128/XP1024/XP10000/XP12000 and IBM PPRC must be installed on the host operating system. For
TC390A operations, special switches and parameters are used to control and monitor TC390A pairs and
groups using PPRC commands.
The following TC390 operations cannot be performed using PPRC commands: async options, and TC390A
group addition/deletion. The async options and groups must be configured using the Command View XP
management station or XP Remote Web Console before you can add any TC390A pairs (CESTPAIR). You
also cannot change the RCU options, initial copy priority, or the DFW to R-VOL pair options using PPRC
commands. For more information on the restrictions associated with using PPRC commands instead of
TC390 through Command View XP or XP Remote Web Console, see ” PPRC Support ” on page 41.
Port configuration (LCP ↔ RCP, RCU target ↔ initiator) is supported through the CESTPATH and CDELPATH
TSO commands only when SVP mode 114 ON (refer to Table 3 on page 20). If SVP mode 114 is OFF,
you must configure the ports using the licensed TC390 software on the Command View XP management
station or XP Remote Web Console before adding paths and after deleting paths.
Table 30 on page 148 lists the TC390 operations and describes the corresponding PPRC TSO and
ICKDSF commands. ” Using PPRC TSO Commands with TrueCopy Asynchronous ” on page 149 provides
instructions for using the PPRC TSO commands with TC390A pairs.
NOTE: For Fibre Channel interface, do not use the CESTPATH and CDELPATH commands at the same
time as the SCSI path definition function of LUN Management. 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 or 2105). PPRC command
extensions are supported when running with 2105 emulation.
The PPRC TSO and ICKDSF commands have required and optional parameters that are not described in
detail in this chapter. These 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 chapter describes the PPRC TSO commands.
