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.
If ScsiIo is NULL, then ASSERT().
If SenseDataLength is NULL, then ASSERT().
If HostAdapterStatus is NULL, then ASSERT().
If TargetStatus is NULL, then ASSERT().
If SenseDataLength is non-zero and SenseData is not NULL, SenseData must meet buffer
alignment requirement defined in EFI_SCSI_IO_PROTOCOL. Otherwise EFI_INVALID_PARAMETER
gets returned.
@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.
@param[in, out] SenseDataLength On input, a pointer to the length in bytes of
the SenseData buffer. On output, a pointer to
the number of bytes written to the SenseData buffer.
@param[out] HostAdapterStatus The status of the SCSI Host Controller that produces
the SCSI bus containing the SCSI target specified by
ScsiIo when the SCSI Request Packet was executed.
See the EFI SCSI I/O Protocol in the UEFI Specification
for details on the possible return values.
@param[out] TargetStatus The status returned by the SCSI target specified
by ScsiIo when the SCSI Request Packet was executed
on the SCSI Host Controller. See the EFI SCSI I/O
Protocol in the UEFI Specification for details on
the possible return values.
@retval EFI_SUCCESS The command was executed successfully.
See HostAdapterStatus, TargetStatus, SenseDataLength,
and SenseData in that order for additional status
information.
@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.
The caller may retry again later.
@retval EFI_DEVICE_ERROR A device error occurred while attempting to send
SCSI Request Packet. See HostAdapterStatus,
TargetStatus, SenseDataLength, and SenseData in that
order for additional status information.
@retval EFI_UNSUPPORTED The command described by the SCSI Request Packet
is not supported by the SCSI initiator(i.e., SCSI
