- Execute Test Unit Ready SCSI command on a specific SCSI target.

- Executes the Test Unit Ready command on the SCSI target specified by ScsiIo.
- If Timeout is zero, then this function waits indefinitely for the command to complete.
- If Timeout is greater than zero, then the command is executed and will timeout after Timeout 100 ns units.

-
- @param[in] ScsiIo A pointer to the SCSI I/O Protocol instance
- for the specific SCSI target.
- @param[in] Timeout The timeout in 100 ns units to use for the execution
- of this SCSI Request Packet. A Timeout value of
- zero means that this function will wait indefinitely
- for the SCSI Request Packet to execute. If Timeout
- is greater than zero, then this function will return
- EFI_TIMEOUT if the time required to execute the SCSI
- Request Packet is greater than Timeout.
- @param[in, out] SenseData A pointer to sense data that was generated by
- the execution of the SCSI Request Packet. This
- buffer must be allocated by the caller.
- If SenseDataLength is 0, then this parameter is
- optional and may be NULL.

- the SCSI bus containing the SCSI target specified by
- ScsiIo when the SCSI Request Packet was executed.

- @retval EFI_NOT_READY The SCSI Request Packet could not be sent because
- there are too many SCSI Command Packets already
- queued. The SCSI Request Packet was not sent, so
- no additional status information is available.
