Sense Data Layout

On AIX 7.1 we have errors with SC_DISK_ERR4 label.

In document "Fibre Channel Planning and Integration: User's Guide and Service Information" I can find SENSE Data description in section "PCI Fibre Channel Adapter, SCSI-3 Protocol (Disk, CD-ROM, Read/Write Optical Device) Error Log Sense Information". But there is no description of value in our case:

We have next Sense Data in our errpt output:

SENSE DATA
Code:
1000 8800 0000 0002 66BA DAD0 0000 0010 0004 0000 0000 0000 0140 0000 0000 0000 
0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 
0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 
0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 
0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 
0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 
0000 0000 0000 0271 7B16 000C D680 0000 0000 0000 0000 0000 0000 0000 0083 0010 
0002 006E 001D

So if we check field Status Validity and SCSI Status field, we have next value:
01 - Indicates that the SCSI Status field (SS) is valid
40 - ??? (the value in document is only 02, 08, 18)

Or may be i don't correctly understand this error log sense information.
So, can you give me link for document described Sense Data layout for SC_DISK_ERR4 errors, or may be you can explain how to interpreted this fields
Thank you.

SCSI status code 40h simply means the task was aborted. It doesn't elaborate on the error.
