Detail Data
aabb xxxx ccdd eeee eeee eeee eeee eeee ffgg hhxx ssss ssss ssss ssss ssss ....
aa Length of the Command Descriptor Block (CDB) sent by the host. In this case,
“0C” bytes.
bb SCSI target address. In this example, SCSI address “00”.
xx Unused or reserved.
cc Start of CDB, cc is the operation code (byte 0). In this case, “A5” which
was an “Move Medium”.

Table 1. Library sense data example
Hex Description
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
that a FID was listed ("86") defines the failure as "The drive detected a drive hardware or media fault". In this case, follow the FID to make a repair. For more information
about Sense Key and ASC/ASCQ fields, see the IBM LTO Ultrium Tape Drive SCSI Reference.
