Resolution

The answer can be found into IBM book: DFSMSdss Storage Administration 

The error 110 means:
The data set was updated and a split or extend is completed, which invalidates any dump that was in progress. When concurrent copy is used, the chances of an in-progress-dump being invalidated by a split or extend is significantly reduced.
 
Here is the information regarding this problem provided by IBM into the same book.
Bypassing backup-while-open processing (OY63531) When DFSMSdss encounters a data set marked as backup-while-open (BWO) eligible, DFSMSdss processes it accordingly.
If the BWO indication is on erroneously, the BWO processing may be bypassed for a logical data set dump. This function is affected by setting the flag at offset X'15' in ADRPATCH.
The settings are listed below:
X'00' BWO processing is performed. Any setting other than X'00' BWO processing is bypassed.
 
Note: For Disk 12.5 release,  for Disk doing the same as DFDSS please apply SO07293.
