Messages ADR709E and IGD17040I might be received when copying or restoring the following types of non-VSAM, multivolume data sets:

• Empty, multivolume data sets dumped with the ALLEXCP keyword
• Undefined data sets
• TTR-organized BDAM data sets
• Data sets with BLKSIZE=0

This function is affected by setting the flag at offset X'14' in ADRPATCH. The settings are listed below:

X'00'

DFSMSdss functions normally; these data sets are allocated as multivolume data sets.

Any setting other than X'00'

These data sets are allocated as single volume data sets.

To set the flag to on dynamically, use the SET PATCH command. To set the flag to on permanently, modify the sample JCL (see Sample JCL) as follows:

//SYSIN DD *
   NAME ADRDSSU ADRPATCH
   VER   14        00
   REP   14        FF
