NOTE Library SCSI-3 Command Set Request Sense Command (03H) SKSV When set to 1, the Sense Key Specific bytes (Bytes 15, 16, and 17) contain valid data. When set to 0, Bytes 15, 16, and 17 are 0.

Library SCSI-3 Command Set
Request Sense Command (03H)
SKSV
When set to 1, the Sense Key Specific bytes (Bytes 15, 16, and 17)
contain valid data. When set to 0, Bytes 15, 16, and 17 are 0.
C/D
1 = Illegal Parameter is in Command Descriptor Block.
0 = Illegal Parameter is in Data Out Phase.
BPV
1 = Bit pointer field is valid.
0 = Bit pointer field is invalid.
Bit Pointer
Specifies which bit is in error. When a multiple bit field is in error, the
pointer points to the most significant bit in the field.
Field Pointer
Specifies which byte is in error. Bytes are numbered starting from 0.
When a multiple-byte field is in error, the pointer points to the most
significant byte of the field.
NOTE
Bytes identified as being in error are not necessarily the bytes that need
to be changed to correct the problem.
Additional Sense Bytes
This field may contain information when the Additional Sense Length
field contains a value greater than 10. See Table 3-3 on page 3-9.
