Data Migration From A Unix-Based Host System To A Ds8000 Storage Unit - IBM DS8000 User Manual

Data migration from a UNIX-based host system to a DS8000 storage
unit
For UNIX-based host systems, you can use a variety of methods for copying or
moving data from one disk drive to another.
The UNIX-based host sees the storage unit as one or more generic disk drive
modules (DDMs). You can use the following methods to migrate data to the
storage unit from open-system hosts that are running UNIX:
v Volume management methods
v Direct copy method
v Backup and restore methods
v Dump and restore commands as well as other commands for example the tar
Environment or Operating System
z/OS operating system
z/VM operating system
command
Data Migration Method
v DFSMSdss (simplest method)
v DFSMShsm
v IDCAMS EXPORT/IMPORT (VSAM)
v IDCAMS REPRO (VSAM, SAM, BDAM)
v IEBCOPY (partitioned data set (PDS),
including load module libraries, and
PDSE)
v ICEGENER (SAM), part of DFSORT
v IEBGENER (SAM)
v Specialized database utilities for CICS,
DB2, or IMS
v Softek Transparent Data Migration Facility
(TDMF), available from IBM as a data
migration service
DFSMS/VM with the following functions:
v DASD Dump Restore—Used to dump
data from disk to tape, restore data from
tape to disk, and copy data between like
disk drive volumes. You cannot use DDR
to copy data between disk devices with
different track formats.
v CMDISK—A DIRMAINT command used
to move minidisks from any device types
that VM supports to any other type.
v COPYFILE—A CMS command used to
copy files or minidisks between devices
with the same or different track modes.
v PTAPE—A Control Program (CP)
command used to dump spool files to
tape and to load files from tape to disk.
