SCSI Sense Codes
The following example shows a typical SCSI error message.
[+6708 72410001 002a9858 0:7] scsi disk: CHECK CONDITION on
disk 0:6:5:0
Read of logical block 509856, count 128
disk sd45a, block 254920, 65536 bytes
Valid = 1, Error code = 0x70
Segment number = 0x00, Filemark = 0, EOM = 0, ILI = 0
Sense key = 0x1, "RECOVERED ERROR"
Information = 0x00 0x07 0xc7 0xe4
[+6709 72410001 002a9a10 0:7] scsi disk: Additional sense
length = 0x0a
Command-specific information = 0x00 0x00 0x00 0x00
Additional sense = 0x18, Qualifier = 0x01
Field replaceable unit code = 0xea
SKSV = 1, C/D = 0, BPV = 0, Bit pointer = 0
Field pointer = 0x0003
The status (CHECK CONDITION) and sense key (RECOVERED ERROR) are
interpreted. The Additional sense and Qualifier codes require interpretation. Use
both codes to locate the interpretation. In the example, the Additional sense (0x18)
and Qualifier (0x01) codes are interpreted as “recovered data with error correction
and retries applied.” and list all possible status and sense key codes. interprets the
Additional sense and Qualifier codes contained in SCSI error messages reported by
the console.
