The HBA_SendScsiInquiry() and HBA_SendScsiInquiryV2() functions send a SCSI Inquiry command as defined in the T10 specification SPC-2 to a remote FCP port. The HBA_SendReportLUNs() and HBA_SendReportLUNsV2() functions send a SCSI Report LUNs command as defined in the T10 specification SPC-2 to a remote FCP port. The HBA_SendReadCapacity() and HBA_SendReadCapacityV2() functions end a SCSI Read Capacity command as defined in the T10 specification SBC-2 to a remote FCP port. RETURN VALUES
The HBA_SendScsiInquiry() function returns the following value: HBA_STATUS_OK The command has completed. Success or failure should be determined by verifying that the sense data does not contain a check-condition. If a check-condition is present, the content of pRspBuffer is undefined. The HBA_ScsiInquiryV2() function returns the following values: HBA_STATUS_OK The command has completed. The complete payload of the SCSI INQUIRY command is returned in pRspBuffer. HBA_STATUS_ERROR_ILLEGAL_WWN The port WWN hbaPortWWN is not a WWN contained by the HBA specified by handle. HBA_STATUS_ERROR_NOT_A_TARGET The identified remote Port does not have SCSI Target functionality. HBA_STATUS_ERROR_TARGET_BUSY The command cannot be sent due to a SCSI overlapped command condition. HBA_STATUS_ERROR An error occurred. The HBA_SendReportLUNs() function returns the following values: HBA_STATUS_OK The command has completed. Success or failure should be determined by verifying the sense data does not contain a check-condition. If a check-condition is present, the content of pRspBuffer is undefined. HBA_STATUS_SCSI_CHECK_CONDITION The HBA detected a check-condition state. Details are present in the pSenseBuffer payload. The content of pRspBuffer is undefined. Not all VSLs support this error condition. Other error values indicate the content of pRspBuffer is undefined. In some cases, the pSenseBuffer can contain sense data. The HBA_SendReportLUNsV2() function returns the following values: HBA_STATUS_OK The command has completed. Sense data must be verified to ensure that it does not contain a check-condition to determine success. If a check-condition is present, the content of pRspBuffer is undefined. HBA_STATUS_ERROR_ILLEGAL_WWN The port WWN hbaPortWWN is not a WWN contained by the HBA specified by handle. HBA_STATUS_ERROR_NOT_A_TARGET The identified remote Port does not have SCSI Target functionality. HBA_STATUS_ERROR_TARGET_BUSY The command cannot be sent due to a SCSI overlapped command condition. HBA_STATUS_ERROR An error occurred. The HBA_SendReadCapacity() function returns the following values: HBA_STATUS_OK The command has completed. Success or failure should be determined by verifying that the sense data does not contain a check-condition. If a check-condition is present, the content of pRspBuffer is undefined. HBA_STATUS_SCSI_CHECK_CONDITION The HBA detected a check-condition state. Details are present in the pSenseBuffer payload. The content of pRspBuffer is undefined. Not all VSLs support this error condition. Other error values indicate the content of pRspBuffer is undefined. In some cases, the pSenseBuffer can contain sense data. The HBA_ScsiReadCapacityV2() function returns the following values: HBA_STATUS_OK The command has completed. Sense data must be verified to ensure that it does not contain a check-condition to determine success. If a check-condition is present, the content of pRspBuffer is undefined. HBA_STATUS_ERROR_ILLEGAL_WWN The port WWN hbaPortWWN is not a WWN contained by the HBA specified by handle. HBA_STATUS_ERROR_NOT_A_TARGET The identified remote Port does not have SCSI Target functionality. HBA_STATUS_ERROR_TARGET_BUSY The command cannot be sent due to a SCSI overlapped command condition. HBA_STATUS_ERROR An error occurred. Other error values indicate the content of pRspBuffer is undefined. In some cases, the pSenseBuffer can contain sense data. ERRORS
See libhbaapi(3LIB) for general error status values. EXAMPLES
Example 1: Send a SCSI inquiry to the given discovered Target port WWN. The following example sends a SCSI inquiry to the given discovered Target port WWN. memset(&inq, 0, sizeof (inq)); memset(&sense, 0, sizeof (sense)); if ((status = HBA_SendScsiInquiry(handle, discPortAttrs.PortWWN, 0, 0, 0, &inq, sizeof (inq), &sense, sizeof (sense))) != HBA_STATUS_OK) { fprintf(stderr, "Unable to send SCSI " "inquiry, reason %d\n", status); continue; } printf(" Vendor: %.*s\n", 8, inq.inq_vid); printf(" Model: %.*s\n", 16, inq.inq_pid); ATTRIBUTES

HBA_OpenAdapter(3HBAAPI), libhbaapi(3LIB), attributes(5) T11 FC-MI Specification BUGS
The HBA_SendScsiInquiry(), HBA_SendReportLUNs(), and HBA_SendReadCapacity() functions do not take a portindex to define through which port of a multi-ported HBA the command should be sent. The behavior on multi-ported HBAs is vendor-specific and can result in the command being sent through the first HBA port, the first HBA port the given PortWWN is connected to, or other vendor-specific behavior. SNIA version 2 defines HBA_ScsiInquiryV2(), HBA_ScsiReportLUNs(), and HBA_ScsiReadCapacity() to take a Port WWN as an argument. This fixes the bug with multi-ported HBAs in HBA_ScsiInquiry(), HBA_SendReportLUNs(), and HBA_SendReadCapacity(). SunOS 5.10 1 Sep 2003 HBA_SendScsiInquiry(3HBAAPI)
