There can be a significant difference between the status of something as reported in some database somewhere and the real world. RMM is a product that runs on your mainframe. You already stated you inadvertently scratched it in RMM and then manually assigned a "correct" status. The RMM status merely reflects the results of these actions. The tape itself is a virtual tape that is physically processed on some other system. You have not shown us anything about what that other system did to the actual media/data. RMM may have told this system to scratch the tape before you changed its status back. > I've tried recalls and get this in syslog - > IEC501A M > 0320,V05537,SL,COMP,DFHSM,DFSMSHSM.S1,DFHSM.HMIGTAPE.DATASE > ARC0645I DFHSM ,DFSMSHSM,0320,T,RESIN1 ,READ ,DATA 751 > ARC0645I (CONT.) CHECK ,0000000001,BSAM > IEF234E K 0320,V05537,PVT,DFHSM,DFSMSHSM The description for DATA CHECK says the control unit or I/O device detected invalid data. There should be some log data on your virtual tape system to confirm this. While virtual tapes can suffer data corruption, it is more likely that it was overwritten and the virtual system is telling HSM there is no data. > Trying not to write off the tapes, only backups/migration copies of datasets > at this point.

You need to provide details. Do you mean you have two backup copies, each on a different tape? Or do you mean you have a backup copy that spans two tapes? Are you saying that attempts to recover a backup copy of a dataset from a different tape has the same problem? What do backup tapes have to do with the status of the ML2 tape that started this thread? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
