-lfs

Output CKD file will be a single file even if it exceeds 2 GB in size.

-o type

Output file type (CKD, CCKD, FBA, CFBA).

arguments:

infile

The input DASD file.

shadowfile

The (optional) name of an associated shadow DASD file.

outfile

The output DASD file.

5.8.4 Examples

Example 1:

Copy the compressed DASD file (CCKD) MVSRES.CCKD to SARESX.148, uncompress it (CKD file) and
replace an already existing file with the same name.

DASDCOPY -r -lfs D:/MVS/DASD/MVSRES.CCKD D:/MVS/DASD/MVSRESX.148

Example 2:

Copy the compressed DASD file (CCKD) MVSRES.CCKD to SARESX.148, uncompress it (CKD file) and
create 2 separate files for systems which do not support large file support.

DASDCOPY D:/MVS/DASD/MVSRES.CCKD D:/MVS/DASD/MVSRESX.148

5.8.5 Sample Utility Output

Sample 1:

Copy the DASD image file MVSRES.CCKD to the new DASD image file SARESX.148. Do not create a
large image file (> 2 GB), create two separate files instead.

D:\HERCULES>dasdcopy D:/MVS/DASD/MVSRES.CCKD D:/MVS/DASD/SARESX.148

5.9.3 Parameter

options:

-v

Display version information and help text.

-z

Build compressed DASD image file using zlib.

-bz2

Build compressed DASD image file using bzip2.

-0

Build compressed DASD image file with no compression (0 = zero).

-lfs

Build a large (uncompressed) DASD file (single file), if it is supported on the plat-
form DASDINIT is running on.

-a

Build a DASD image file that includes alternate cylinders. This option is ignored if
the size is manually specified.

-r

Build raw DASD image file (no VOL1 or IPL track).

-b

Make the wait PSW in the IPL1 record a BC-mode PSW. If this option is not spe-
cified, the wait PSW will be an EC-mode PSW.
