SCSI Decoder
About
SCSI error messages appearing in log files can many times be convoluted and non-trivial to understand. This tool is designed to help decode SCSI error messages and provide solutions to resolve issues more quickly and easily.
Usage
The user has the ability to parse SCSI error messages from both log files and/or a log file snippets. The app will parse all SCSI error messages and marshall each into the following fields:
SD: SCSI Device
SCSI Error Code: Hexadecimal error code
ASC: Additional Sense Code
ASCQ: Additional Sense Code Qualifier
Found: Number of times error was found
The user then has the ability to individually diagnose each SCSI error message. This diagnose action will return solutions that when clicked will open in a new browser tab.

Gengsheng,
This tool is looking for a "SCSI error: return code" which the text you posted does not contain. This error code is the most important in identifying an appropriate solution. Below is an example:
Dec 31 18:14:40 n118277vaps2015 kernel: sd 1:0:0:0: SCSI error: return code = 0x08000002
Dec 31 18:14:40 n118277vaps2015 kernel: Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE,SUGGEST_OK
Dec 31 18:14:40 n118277vaps2015 kernel: sdc: Current: sense key: Illegal Request
Dec 31 18:14:40 n118277vaps2015 kernel: ASC=0x2 ASCQ=0x10
