scsi_id_t
Structure
The scsi_id_t
structure provides command ID information.
typedef struct scsi_id { uint64_t id_cmd; uint64_t id_timestamp; } scsi_id_t
The id_cmd
member represents an identifier of the command. It can be used to match a SCSI request with a SCSI response. The value of the id_cmd
member can be reused when the command execution is complete. Therefore, the id_cmd
member must be used with the id_timestamp
member or you must sort the script output according to the another time stamp.
The id_timestamp
member is a time stamp of the SCSI command request in nanoseconds. It can be used with a DTrace build-in variable time stamp to do various time related calculations.
