  Solution - both H1 and H2 devices must be in the same Esoteric.
  Modify the EDT in the Activate IODF to include both primary and
  secondary
  devices and ACTIVATE a new IODF.
  
  The activate can be performed as a SOFTWARE ONLY ACTIVATE.
  As per Redbook:
  Best Practices for IBM DS8000 and IBM z/OS HyperSwap with IBM
  Copy Services Manager

  .
  6.2.11  Allocation and esoteric names
  
  Esoteric definitions such as SYSDA must specify both primary
  and secondary devices for allocations to succeed, regardless of
  which set of disks is currently considered primary.
