TrueCopy for Mainframe operations involve the HP storage system at the main and remote sites,
the physical communications paths between the main and remote storage systems, and the XP
TrueCopy software. TrueCopy for Mainframe copies the original online data at the main site to
the offline backup volumes at the remote site via the dedicated Fibre Channel remote copy
connections. The TrueCopy for Mainframe software is included in the Remote Web Console Java
application, and all TrueCopy for Mainframe functions and operations can be performed from
within a web browser. The I/O time-stamping host software function (provided by MVS DFSMSdfp)
is required for TrueCopy for Mainframe Asynchronous consistency groups which span multiple
storage systems. Error reporting communications (ERC) is required for effective disaster recovery
with TrueCopy for Mainframe.
