Hi Lizette, The problem is that the DFSMSdss COPYDUMP command does not 'reblock' a dump data set. So, if the blocksize of the input dump data set is 262144, then the blksize of the output dump data set must also be 262144. Also, the only supported way to copy a DFSMSdss produced dump data set is using the COPYDUMP command.
