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 DDMs. You can
use the following methods to migrate data to the storage unit from open-system
hosts that are running UNIX:
Environment or Operating System
Linux environment
z/OS operating system
z/VM operating system
VSE/ESA operating system
Data Migration Method
Remote Mirror and Copy (when available)
v DFDSS (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 Amdahl 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.
v Backup and Restore dialogs
v VSE fastcopy command to move volumes
and files between devices with identical
track formats.
v VSE ditto command to copy files.
v VSE power command to transfer the
spool queue from one device to another.
v VSE REPRO or EXPORT/IMPORT
function to move any VSAM data set.
