Formatting multiple dasd with the YaST DASD disk management fails with:
Error Disk formatting failed: Error code 2
For example, 4 disks in parallel will fail 1 out of 4 or 5 times. In the progress bar, one sees only 2 or 3 of the 4 disks formatting, and no progress for the other disks. Then a pop-up will show the error. This can be intermittent and a rerun may succeed the next time. 


The s390-tools updates released May 2016 include the solution to resolve this problem. Please install the recommended updates.
