CONFIG_FUSION_ISENSE: Enhanced SCSI error reporting

General informations

The Linux kernel configuration item CONFIG_FUSION_ISENSE:

Help text

The isense module (roughly stands for Interpret SENSE data) is completely optional. It simply provides extra English readable strings in SCSI Error Report(s) that might be generated from the Fusion MPT SCSI Host driver, for example when a target device returns a SCSI check condition on a I/O. Without this module loaded you might see:

SCSI Error Report =-=-= (ioc0,scsi5:0) SCSI_Status=02h (CHECK_CONDITION) Original_CDB[]: 2A 00 00 00 00 41 00 00 02 00 SenseData[12h]: 70 00 02 00 00 00 00 0A 00 00 00 00 04 02 02 00 00 00 SenseKey=2h (NOT READY); FRU=02h ASC/ASCQ=29h/00h

Where otherwise, if this module had been loaded, you would see:

SCSI Error Report =-=-= (ioc0,scsi5:0) SCSI_Status=02h (CHECK_CONDITION) Original_CDB[]: 2A 00 00 00 00 41 00 00 02 00 - "WRITE(10)" SenseData[12h]: 70 00 02 00 00 00 00 0A 00 00 00 00 04 02 02 00 00 00 SenseKey=2h (NOT READY); FRU=02h ASC/ASCQ=29h/00h "LOGICAL UNIT NOT READY, INITIALIZING CMD. REQUIRED"

Say M for "Enhanced SCSI error reporting" to compile this optional module, creating a driver named: isense.

NOTE: Support for building this feature into the kernel is not available, due to kernel size considerations.
