NOTE Library SCSI-3 Command Set Log Sense Command (4DH) Sense Key See Table 3-1 on page 3-3. Additional Sense Code (ASC) The Additional Sense Code specifies detailed information related to the error reported in the Sense Key field. See Table 3-2 on page 3-4. Additional Sense Code Qualifier (ASCQ) The Additional Sense Code specifies detailed information related to the error reported in the Sense Key field. See Table 3-2 on page 3-4. SKSV When set to 1, the Sense Key Specific bytes contains valid data. When set to 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. Bytes identified as being in error are not necessarily the bytes that need to be changed to correct the problem. Error Code Determined by fault isolation, this error code indicates the cause of the failure. The values of the hardware error codes are in Table 3-4 on page 3-16. Chapter 2 2- 143

Library SCSI-3 Command Set
Log Sense Command (4DH)
Sense Key
See Table 3-1 on page 3-3.
Additional Sense Code (ASC)
The Additional Sense Code specifies detailed information related to the
error reported in the Sense Key field. See Table 3-2 on page 3-4.
Additional Sense Code Qualifier (ASCQ)
The Additional Sense Code specifies detailed information related to the
error reported in the Sense Key field. See Table 3-2 on page 3-4.
SKSV
When set to 1, the Sense Key Specific bytes contains valid data. When
set to 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.
Error Code
Determined by fault isolation, this error code indicates the cause of the
failure. The values of the hardware error codes are in Table 3-4 on
page 3-16.
