Dear all: Would you please tell me where I can find the SCSI initial sequence? Since I read the spec, I want to know the sequence of using them. For example, if I plug in a usb flash, what are the correct and proper sequences I should use before I call READ_10. appreciate your help, miloody 2009/3/24 loody <miloody@xxxxxxxxx>: > Hi all: > thanks for your kind help, > Sincerely Yours, > miloody > 2009/3/24 Mark Brown <markb@xxxxxxxxxxxxxxxxxxxxx>: >> 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. >> >> http://en.wikipedia.org/wiki/SCSI_CDB >> http://en.wikipedia.org/wiki/SCSI_Write_Commands >> >> Enjoy! >> >> -- Mark >> >> On Mar 24, 2009, at 4:21 AM, Sandeep K Sinha wrote: >> >>> On Tue, Mar 24, 2009 at 1:27 PM, loody <miloody@xxxxxxxxx> wrote: >>>> >>>> Hi: >>>> >>>> 2008/3/15 vichy <vichy.kuo@xxxxxxxxx>: >>>>> >>>>> Dear all: >>>>> I found there is number at the end of SCSI commands like below: >>>>> Command document >>>>> WRITE(6) SBC >>>>> WRITE(10) SBC >>>>> WRITE(12) SBC >>>>> Could someone tell me what the number, (6), (10) and (12) mean? >>>>> Appreciate your help, >>>>> vichy >>>>> >>>>> >>>>> -- >>>>> To unsubscribe from this list: send an email with >>>>> "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx >>>>> Please read the FAQ at http://kernelnewbies.org/FAQ >>>> >>>> Does anyone where the implementation about SCSI commands in linux driver? >>>> I want to compare the source with the spec. >>> >>> Look into scsi_ioctl( ). >>> Its located in linux/drivers/scsi/scsi_ioctl.c >>> >>> >>> HTH, >>> >>>> Sincerely Yours, >>>> miloody >>>> >>>> -- >>>> To unsubscribe from this list: send an email with >>>> "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx >>>> Please read the FAQ at http://kernelnewbies.org/FAQ >>>> >>>> >>> >>> >>> >>> -- >>> Regards, >>> Sandeep. >>> >>> >>> >>> >>> >>> >>> “To learn is to change.
