TC390 and SVP error codes.

Using PPRC commands for TrueCopy
Overview of PPRC commands
The XP12000/XP10000 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 XP12000/XP10000 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 XP Command View
Advanced Edition Software server 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 XP Command View Advanced Edition Software or XP Remote Web
Console, see ” PPRC support ” on page 40.
Port configuration (LCPRCP, RCU targetinitiator) is supported through the CESTPATH and CDELPATH
TSO commands only when system option mode 114 ON (see Table 3 on page 18). If system option mode
114 is OFF, you must configure the ports using the licensed TC390 software on the XP Command View
Advanced Edition Software server or XP Remote Web Console before adding paths and after deleting
paths.
NOTE: Even if you set ON for system option mode 114, initiator ports will not automatically change to
RCU target ports, nor vice versa, when these ports are in initiator/external mix mode.
Table 33 on page 158 lists the TC390 operations and describes the corresponding PPRC TSO and ICKDSF
commands. ” Using PPRC TSO commands with TrueCopy Asynchronous ” on page 160 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, 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 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.
When the CESTPATH command is executed, the following processing is executed sequentially.
