Cause

When both the SRC and TGT devices are in the QUERY set of devices, the duplicate rows occur.

Two rows are created, one for the SRC device 2A4 and one for the TGT device 2AC.

The rows are sorted by SRC. The report is by SRC, so this causes the two rows to come together and appear as duplicates.

Resolution

The duplicate row is removed on the QUERY SNAPSHOT DEV(ALL) output.

Workaround:  
  • The duplicate row can be ignored. 
Permanent Fix:
  • As of January 24, 2022, for Mainframe Enablers 8.5, Dell Engineering is investigating this issue. A permanent solution is still in progress. Contact the Dell Customer Support Center or your service representative for further assistance and quote this article number.
