DESCRIPTION
     The HBA_SendScsiInquiry() and HBA_SendScsiInquiryV2()  func-
     tions  send  a  SCSI  Inquiry  command as defined in the T10
     specification SPC-2 to a remote FCP port.


     The HBA_SendReportLUNs()  and  HBA_SendReportLUNsV2()  func-
     tions  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 com-
         mand 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.

         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 com-
         mand 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

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().
