Hi,
If you want to see the SCSI mid-layer implementation check out:
drivers/scsi/scsi.c
If you are curious about the SCSI commands sent to a SCSI disk you can
look at:
drivers/scsi/sd.c
SCSI tape:
drivers/scsi/st.c
SCSI optical media (CDs/DVDs)
drivers/scsi/sr.c
SCSI enclosures
drivers/scsi/ses.c
For the embedded email from Vichy:
6,10,12 and even 16 is the (CDB) command length.
In the case of Write CDB size allows you to adjust the LBA, Transfer
Length, etc. Some older targets do not handle larger CDB sizes.

Enjoy!

Dear all:
I found there is number at the end of SCSI commands like below:
Command document
WRITE(6) SBC
WRITE(10) SBC

Could someone tell me what the number, (6), (10) and (12) mean?
Appreciate your help,
