47 Executes the Test Unit Ready command on the SCSI target specified by ScsiIo.\r
48 If Timeout is zero, then this function waits indefinitely for the command to complete.\r

56 @param[in] ScsiIo A pointer to the SCSI I/O Protocol instance\r
57 for the specific SCSI target.\r
58 @param[in] Timeout The timeout in 100 ns units to use for the execution\r
59 of this SCSI Request Packet. A Timeout value of\r
60 zero means that this function will wait indefinitely\r
61 for the SCSI Request Packet to execute. If Timeout\r
62 is greater than zero, then this function will return\r
63 EFI_TIMEOUT if the time required to execute the SCSI\r
64 Request Packet is greater than Timeout.\r
65 @param[in, out] SenseData A pointer to sense data that was generated by\r
66 the execution of the SCSI Request Packet. This\r
67 buffer must be allocated by the caller.\r
68 If SenseDataLength is 0, then this parameter is\r
69 optional and may be NULL.\r
70 @param[in, out] SenseDataLength On input, a pointer to the length in bytes of\r
71 the SenseData buffer. On output, a pointer to\r
72 the number of bytes written to the SenseData buffer. \r
73 @param[out] HostAdapterStatus The status of the SCSI Host Controller that produces\r
74 the SCSI bus containing the SCSI target specified by\r
75 ScsiIo when the SCSI Request Packet was executed.\r
76 See the EFI SCSI I/O Protocol in the UEFI Specification\r
77 for details on the possible return values.\r
78 @param[out] TargetStatus The status returned by the SCSI target specified\r
79 by ScsiIo when the SCSI Request Packet was executed\r
80 on the SCSI Host Controller. See the EFI SCSI I/O\r
81 Protocol in the UEFI Specification for details on\r
82 the possible return values. \r
83\r
84 @retval EFI_SUCCESS The command was executed successfully.\r
85 See HostAdapterStatus, TargetStatus, SenseDataLength,\r
86 and SenseData in that order for additional status\r
87 information.\r
88 @retval EFI_NOT_READY The SCSI Request Packet could not be sent because\r
89 there are too many SCSI Command Packets already\r
90 queued. The SCSI Request Packet was not sent, so\r
91 no additional status information is available.\r
92 The caller may retry again later.\r
93 @retval EFI_DEVICE_ERROR A device error occurred while attempting to send\r
94 SCSI Request Packet. See HostAdapterStatus,\r
95 TargetStatus, SenseDataLength, and SenseData in that\r
96 order for additional status information.\r
97 @retval EFI_UNSUPPORTED The command described by the SCSI Request Packet\r
98 is not supported by the SCSI initiator(i.e., SCSI\r
99 Host Controller). The SCSI Request Packet was not\r
100 sent, so no additional status information is available.\r
101 @retval EFI_TIMEOUT A timeout occurred while waiting for the SCSI Request\r
102 Packet to execute. See HostAdapterStatus, TargetStatus,\r
