status:由 SCSI 标准定义的 SCSI 状态字节。 总而言之,当用这种方法传输数据时,cmdp必须指向其长度存储在cmd_len中的 SCSI CDB;sbp指向最大长度为mx_sb_len的用户内存。如果出现错误,将把检测数据写回到这个位置。dxferp指向内存;数据将根据dxfer_direction传输到 SCSI 设备或从中传输出来。 最后,我们看看 inquiry...

To execute SCSI commands, a target driver must first allocate a scsi_pkt(9S) structure for the command, specifying its own private data area length, the command status, and the command length. The HBA driver is responsible for implementing the packet allocation in the tran_init_pkt(9E) ...
The target-mode device driver builds the appropriate command block to execute this operation, including ORing in the 3-bit logical unit number (LUN) identifier in the SCSI command based on the configuration information for this device instance. The returnederrnoglobal variable is generated and thest...
