Table 5.2 Sense and subsense codes (5 of 5)
C* Q* Name Explanation
Sense
key
45 00 Select/Reselect failure A response wait time-out from the INIT was detected in the
RESELECTION phase.
B
47 00 SCSI parity error A parity error was detected on the SCSI data bus. B
48 00 INITIATOR DETECTED
ERROR message received
The INITIATOR DETECTED ERROR message was received from
the INIT.
B
49 00 Invalid message error An unsupported or inappropriate message was received. B
4C nn Logical unit failed self-
configuration
The IDD's initial setup failed. ('nn' is a Fujitsu unique code)
• A1: SA Read error (any 3/11/** error during SA read)
• A3: SA Read error (any 3/13/** error during SA read)
• A4: SA Read error (any 3/14/** error during SA read)
• A5: SA Read error (any 3/15/** error during SA read)
• A7: SA Read error (any 4/44/** error during SA read)
• A8: Invalid SA (Header/Check Sum)
• E0: Initial calibration failed
4
4D nn Tagged overlapped
command
Before completing one command execution, new command having
the same tag number was issued to the same logical unit. (nn=queue
tag number)
B
4E 00 Overlapped commands
attempted
1) Before execution of an untagged command was completed, the
same INIT issued a new command to the same LUN.
2) Before execution of a tagged command was completed, the same
INIT issued a command to the same LUN with the same tag. Or,
an untagged command was issued when not in the sense hold
state.
B
55 04 Insufficient Registration
Resource
PERSISTENT RESERVATION OUT command is issued from
insufficient device server resource.
5
01 Spindle synchronized The rotational synchronization operation was completed. 65C
02 Spindle not synchronized. Rotational synchronization deviated. 6
5D nn SMART predictive failure SMART related sense data
•
12: The read error rate attribute has reached the failure threshold.
•
14: The frequency of grown defect allocation attribute has
reached the failure threshold.
•
43: The seek error rate attribute has reached the failure threshold.
•
56: The spin up time attribute has reached the failure threshold.
•
64: The remaining alternate sector count attribute has reached the
failure threshold.
•
FF: The drive is in test mode.
0, 1, 6
90 00 Initiator's SCSI ID not
identified
Since the SCSI ID of the INIT was not notified in the SELECTION
phase, the RESERVE, RESERVE EXTENDED, RELEASE AND
RELEASE EXTENDED commands cannot be executed.

C4 nn Drive Failure A serious error was detected in the drive's control system. ('nn' is a
Fujitsu unique code)
•
00: Abnormal Rotation of Spindle Motor
•
01: Any error at Spindle Motor Start
•
30: On track failure
