ISPF adds entries to the ISPF log to record when certain functions are called and when TSO commands are issued. You can use information in the ISPF log to diagnose errors in DFSMSrmm.

If the ISPF log is empty, your user profile is not set for logging error data, inter-module trace data, or trace-point trace data. Use the ISPF PARMS application to change your log defaults. Then attempt to re-create the failure.
