Table 9-13 Data mover for data set copy (to device of same geometry)
Data set type Data mover Notes
Sequential DFSMSdss
Partitioned (not PDSE) DFSMSdss / IEBCOPY All partitioned data sets that are not load modules are
compressed during a copy. Specify NOPACKING if FlashCopy is
to be used.
Partitioned (not PDSE)
load modules
DFSMSdss / IEBCOPY If copying partitioned load modules with REBLOCK, DFSMSdss
calls IEBCOPY to copy the data set to a like device.
Partitioned data set
extended (PDSE)
DFSMSdss / IGWFAMS DFSMSdss calls the IGWFAMS utility when you are converting a
PDS to a PDSE.
Direct nonrelative block

ESDS DFSMSdss / IDCAMS DFSMSdss calls IDCAMS if the target CISIZE, CASIZE, physical
record size, or physical block size of the target is different from
that of the source.
RRDS DFSMSdss / IDCAMS DFSMSdss calls IDCAMS if the target CISIZE, CASIZE, physical
record size, or physical block size of the target is different from
that of the source.
LDS DFSMSdss/IDCAMS DFSMSdss calls IDCAMS if the target CISIZE, CASIZE, physical
record size, or physical block size of the target is different from
that of the source.
KSDS or VRRDS DFSMSdss / IDCAMS DFSMSdss calls IDCAMS if any of the following are true:
The CISIZE, CASIZE, physical record size, physical block
size, imbed, or span attributes of the target are different from
that of the source.
The target data set is SMS and has an imbedded index or
has key ranges, and the target volume count is greater than
one.
The target data set is non-SMS, the source component or
components span multiple volumes, and there is not enough
space on one target volume to contain the entire data set.
Key range data set DFSMSdss / IDCAMS DFSMSdss calls IDCAMS if the source and target CASIZE,
physical record size, or physical block size are different; if the
components span multiple volumes; for a KSDS with IMBED and
either the source HURBA=HARBA or it has extended indexes.
Extended-format VSAM DFSMSdss / IDCAMS DFSMSdss calls IDCAMS if the target CISIZE, CASIZE, physical
record size, or physical block size of the target is different from
that of the source.
