Hi Rex, How have you activated tape protection in your environment - SETROPTS, PARMLIB(DEVSUPxx), or a Tape Management product option? What Tape Management product do you have?
Not that this may matter, but does your ID have READ access to FACILITY ICHBLP or your Tape Management product's equivalent? If it does, have you tried the function with an ID that does not have this access? Regards, Bob Robert S.

According to the FileManager documentation - which I verified on my system - granting any kind of access (read, update, alter, it doesn't matter) either grants you access to the function or denies it (access=none). For example, if I grant READ access to FILEM.TAPE.OUTPUT, I have access to update tapes. Likewise if I grant ALTER access to FILEM.TAPE.INPUT, all that gives me access to is tape browse type functions like tape browse and tape label display. These are just toggles to the function within FileManager. The problem that I am running into is that for example, if I have 2 production datasets on tape, one with GL information and the other with the payroll information on it, and I need to grant an accountant access to the GL information but not the payroll, it appears that I can't. It looks like FileManager doesn't check dataset level access. Once I grant access to FILEM.TAPE.INPUT, a user can browse data on any tape on the system, regardless of whether they have access at a dataset level or not. I'm hoping I just have something set wrong, but I can't seem to get FileManager to look at dataset level RACF protection on tapes. As I mentioned earlier, I have a mixed GDG, with some generations on disk and others on tape. If I grant an ID access to the TB function, whether through FILEM.FUNCTION.TB or through the grouping profile FILEM.TAPE.INPUT, I can look at the data on the tape, even though I can't look at the other generation that's on disk through FileManager. Test I just reran this morning. GDG with 5 generations, 4 on disk, 1 on tape. ISPF edit on one of the disk based generations I got RACF security violation, ACCESS INTENT(READ ) ACCESS ALLOWED(NONE ) Filemanager option 2 edit on the same generation as ISPF: ACCESS INTENT(READ ) ACCESS ALLOWED(NONE ) Filemanager option 4.1, Tape Browse: FILEM.FUNCTION.TB CL(FACILITY) ACCESS INTENT(READ ) ACCESS ALLOWED(NONE ) Change FILEM.FUNCTION.TB to give me READ access to the FACILITY profile Filemanager option 4.1: I got access to browse the data Filemanager option 2 with the tape generation: I got access. Looks like it's time for a question to IBM FM folks to see if this is WAD. In my mind, this is a security hole.
