Hello,
And keep in mind that all 5 files must have compatible dcb info. When you read the dd with the 5-file concatenation, the file with the largets blksize should be the first file named. |

the alternative ( recommended ) is to explicitly define a large enough blksize in the first DD...
for dasd datasets, blksize=32760 should be enough
but if I remeber correctly the restriction was relaxed in some recent os release |
