Hello list,
  I have a question regarding IEC507D:
  I am using HSM and CA1, and the tape volumes used by HSM is protectd
  by expiration date, and when HSM thinks the contents of a tape
  volume is expired,it will notify CA1 via an exit similar to the exit
  used by RMM interface with HSM.
  However there is a problem: the data sets reside on expired volumes
  are not expired,they have expiration date as 99/365.
  When next time there is a scratch mount request,the tape volume is
  mounted to service the request, IEC507D will kick in.
  My questions are:
  1.What part of operating system component issue the mesage,check the
  expiration data of dataset?
  I check the message and found it was issued by DFSMSdfp,moudle
  IFG0194C.

  2.Why doesn't TMS(Tape management subsystem) check and issue the
  error mesage?
  Why does TMS leave the task to SMSdfp to check it?
  It seems TMS only checks if dataset names matches,volume status
  maches,volume expiration status maches, but not individual dataset
  expiratation status if the volume is expired via an exit or via
  command(like HSM's DELVOL)?
  
  3.Is there a customized parameter in CA1 to let customer suppress
  the appearance of IEC507D just like EXPDTCHECK in RMM?

Best regards,
 victor
