Table B-22: Embedded Data To Stream Device Segment Descriptor - Spectra Logic Spectra S50 User Manual

The Inline Data Number of Bytes field specifies the number of bytes of inline data that
are to be transferred to the stream device. A value of zero will not be considered an
error.
If the sum of the Inline Data Offset and the Inline Data Number of Bytes values
exceeds the value in the Inline Data Length field (see Table B-22), the copy manager
will terminate the command with a CHECK CONDITION status. The sense key will be set to
COPY ABORTED and the additional sense code will be set to INLINE DATA LENGTH EXCEEDED.
Embedded Data to Stream Device Operation
The segment descriptor format shown in Table B-22 instructs the copy manager to
write embedded data from the segment descriptor to a stream device.

The Descriptor Type Code field is described in Descriptor Type Codes on page 122 and
Segment Descriptors on page 133. Descriptor type code 05h (embedded->stream)
instructs the copy manager to write embedded data from the segment descriptor to a
stream device. The embedded data will be read from the segment descriptor. The data
