DFR3517A ENTER 'YES' AFTER ENSURING I/O PREVENTION FOR THE FAILED ACTIVE IMS HAS COMPLETED

Explanation
 The recovering system is the IMS XRF complex. IMS DEDB Fast Recovery requests
the operator to check whether the I/O prevention has been completed
for both the failing active IMS and
the failing alternate IMS.

System action
 IMS DEDB Fast Recovery waits
for the operator response. If the reply is YES, IMS DEDB Fast Recovery recovers
the related DEDB areas from the I/O toleration buffers
and continues. Otherwise, it issues a DFR3525A message.

Operator response
 Enter YES after ensuring that the
I/O prevention has been completed for both IMS subsystems. If it is impossible to complete
the processing because of an MVS™ failure,
rerun the job after forcing the I/O prevention for both the active
and alternate IMS by resetting
the CEC.
