I'm new to this scsi stuff. Is there any good online reference where I can look up CDBs and the format of responses etc. For e.g. I know that 0x43 is READ_TOC but I have no idea how to construct the CDB and what format to response is. You should look into t10.org to get SAM SPC SBC specs first , All SCSI command & response format could be found there , or you just look the kernel source in driver/scsi -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
