• Closed as program error.

Error description

• When a  NAS backup to a remote drive (devtype=NAS, storage
  pool dataformat=*dump) exceeds 2.1 Terabytes in size, the
    next backup written to the same tape will overwrite the
    last backup on the tape.
    The Tivoli Storage Manager is tracking the number of
    kilobytes during the write operation of an NDMP backup.
    This value is eventually used to determine the append
    position of the volume. If number of kilobytes written
    exceeds the maximum value of a signed int32
    (2,147,483,647) variable, then the append position is
    not incremented ausing the backup to be overwritten
    on the next backup to this tape.
  Tivoli Storage Manager Versions Affected:
    All platforms and version.
  Customer/L2 Diagnostics (If Applicable):
    A trace using the flags PVRROPEN, PVRRCLOSE, PVRRREAD,
    PVRRWRITE, PVRRPOS, PVRRERROR, PVRVOL of the backup
    will show the following output:
  
    [ndmpspi.c][nnnn][spiTrace]: Leaving spiStoreSeg, rcNdmp
        0, wrote 2516120558592 bytes, handle: 0x6a1f688.
  
    NOTE: this is the key trace statement below, which is
      displayed at the end of the backup or tape change. The
      negative number for kbytes indicates the error:
    [pvrnas.c][nnn][NasWrite]:In NasWrite, mpP is 0x6386868,
        kbytes is -1837818313
    [asalloc.c][nnnn][AsApplySeg]:AsApplySeg: Archival segment
        being applied (VolId=10463, Start=13, Offset=0,
        Size=2516120558592).
    Also, during a point in time restore operation of the first
    image found on the volume the last image backed up to the
    volume is always restored.
  
  Initial Impact:
    High
  Additional Keywords:
    NDMP OVERWRITE
  

Local fix

•   If the backup image exceeds 2.1 TB in size, limit one
    image to a volume.
