TTOC does not tell you anything about the tape. It only tells you what HSM thinks is on the tape. The fact that HSM is getting I/O errors tells you that HSM's opinion and reality are out of sync. You still have no idea if the tape was overwritten.
Mount the tape BLP and use IDCAMS to print file 1 in dump format. > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:[email protected]] On > Behalf Of Michaud, Bruce > Sent: Wednesday, May 20, 2015 11:26 AM > To: [email protected] > Subject: Re: AUDIT function output in HSM ? > > Replies below CAPS - to make it easier to find answer, not yelling :) > > Bruce Michaud > Mainframe technical support > US Airways 52N-UIT > > [email protected] > Phone - 480-693-7754 > > > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:[email protected]] On > Behalf Of retired mainframer > Sent: Wednesday, May 20, 2015 10:28 AM > To: [email protected] > Subject: Re: AUDIT function output in HSM ? > > > -----Original Message----- > > From: IBM Mainframe Discussion List [mailto:[email protected]] > > On Behalf Of Michaud, Bruce > > Sent: Wednesday, May 20, 2015 6:55 AM > > To: [email protected] > > Subject: Re: AUDIT function output in HSM ? > > > > So let me change gears slightly. > > If I enter this command - > > AUDIT MEDCTL VOLUMES(V05537) > > > > I get this output back in HSM - > > /* MSG 916 - I/O ERROR ON VOLUME V05537 > > /* MSG 998 - AUDIT CONTINUING, COMMAND ACTIVITY LOG MAY > CONTAIN > > ADDITIONAL INFOR > > /* FIXCDS T 'L2-V05537-0000' PATCH(X'0000003C' X'00000000') > > /* FIXCDS T 'L2-V05537-0000' PATCH(X'00000040' X'0000') > > - END OF - ENHANCED AUDIT - LISTING - > > > > Can I just enter these above FIXCDS commands and 'fix' this ML2 tape ? > > Thanks again for any help. > > It depends on what the real problem with the tape is. > > Is it a physical tape or a virtual one? > VIRTUAL > > Has it been overwritten?
