5.7 DASDCONV (DASD i
mage file conversion program)

5.7.1 Function

The DASD CKD image conversion utility is used to convert HDR-30 CKD image files or compressed (.gz)
image files to the AWSCKD format that is used by the Hercules Emulator. The .gz compressed format
was recently used by IBM to ship the ADCD DASD image files for the FLEX-ES emulator.

5.7.3
Parameter

options:

-r

Replace the output file if it already exists.

-lfs

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

-q

The "-q" (quiet) option suppresses the progress messages.


arguments:

infile

The name (and optionally path) of the input HDR-30 CKD image file or the name of
the compressed (.gz) image file.

-

If the hyphen is specified instead of a filename, then DASDCONV reads from stdin.
This gives the possibility of piping the output from gunzip in the case that DASD-
CONV was generated without gzip support.

outfile

The name of the AWSCKD image file to be created.

5.7.4 Examples

Example 1:

Convert a .gz compressed DASD image file to AWSCKD format. Create a large file (> 2 GB) and replace
the output file if it already exists.

DASDCONV -r -lfs D:\MVS\DASD\MVSRES.GZ D:\MVS\DASD\MVSRES.CKD
