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 
address mode
DFSMSdss
Direct relative block 
address mode
DFSMSdss Specify the DFSMSdss RELBLOCKADDRESS parameter.
Indexed sequential to 
same track. Target 
volume uses VTOC 
index. Target space 
available.

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.
