OPEN/EOV tape volume security and verification exit (Eioption 16)

z/OS DFSMSdss Storage Administration
SC23-6868-01

This exit point is called when DFSMSdss is ready to open a tape. You can bypass password and expiration date checking for tape volumes or reject the volume and request a scratch tape with this exit by placing a return code in the first word of the record pointed to by EIRECPTR. DFSMSdss passes this return code to OPEN/EOV. The EIRECPTR points to the parameter list described by the IECOEVSE macro.

The valid return codes are:
0
Continue normal processing
16
Record modified
20
Disconnect exit
32
End function. This return code is only valid for a full dump and a full restore operation
