aa Length of the Command Descriptor Block (CDB) sent by the host. In this case,
“0C” bytes.

A5 SCSI Command (in this case Move Medium).
70 Byte 0 of Library Sense Data (Valid Data).
04 Sense Key (in this case Hardware Error).
818F ASC/ASCQ (extra sense code/additional sense code qualifier), in this case a
“Cannot Find Slider Block” error.
SCSI sense data - tape drive error
The following example of SCSI Sense Data was received from a System p Open System host and shows a
Tape Drive Failure and what the sense data would look like. Like the SCSI sense data in the previous
example, this data contains valid sense data as defined by the hex “71” in the first sense byte position.
Therefore, there is valid data to rely on. While the data shows a TAPE_ERR2, further review of the
ASC/ASCQ (Media Load or Eject Failed) points more to a problem with the media or the drive. The fact
