The functions in this library access Fibre Channel and/or Sereal Attached SCSI HBA data depending on vendor provided implementation underneath.
HBA information is provided through a standard interface in a vendor independent manner. This common interface provides access to the following information:
Local HBA attributes
Local HBA port attributes and statistics
Mapping between discovered devices and operating system SCSI information
Discovered devices port attributes
SCSI commands for discovered devices (Report LUNS, Read Capacity, and Inquiry)
Storage Managment Protocol commands to discover Serial Attached SCSI configuration details
Common Transport commands to discover Fibre Channel Fabric details
The shared object libSMHBAAPI.so.1 provides the public interfaces defined below. See Intro(3) for additional information on shared object interfaces.

Client applications link with the Common Library (using -lSMHBAAPI) to access the interfaces. The Common Library dynamically loads individual Vendor-Specific Libraries (VSL) listed in /etc/smhba.conf and described on smhba.conf(4).
Using the libSMHBAAPI involves the following steps:
1. Optionally determining the version of the library by calling SMHBA_GetVersion().
2. Initializing the Common Library by calling HBA_LoadLibrary().
3. Determine the number of HBAs known to the common library by calling HBA_GetNumberOfAdapters().
4. Determine each HBA name in turn by calling HBA_GetAdapterName().
5. Open each HBA in turn by calling HBA_OpenAdapter().
6. Operate on a given HBA by calling the following:
SMHBA_GetAdapterAttributes()
SMHBA_GetAdapterPortAttributes()
SMHBA_GetDiscoveredPortAttributes()
SMHBA_GetPortAttributesByWWN()
SMHBA_GetNumberofPorts()
SMHBA_GetPortType()
SMHBA_GetProtocolStatistics()
SMHBA_GetPhyStatistics()
SMHBA_GetBindingCapability()
SMHBA_GetBindingSupport()
SMHBA_SetBindingSupport()
SMHBA_GetTargetMapping()
SMHBA_GetPersistentBinding()
SMHBA_SetPersistentBinding()
SMHBA_RemoveAllPersistentBindings()
SMHBA_GetLUNStatistics()
SMHBA_SendScsiInquiry()
SMHBA_SendReportLuns()
SMHBA_SendReadCapacity()
SMHBA_RegisterForAdapterAddEvents()
SMHBA_RegisterForAdapterEvents()
SMHBA_RegisterForAdapterPortEvents()
SMHBA_RegisterForAdapterPortStatEvents()
SMHBA_RegisterForAdapterPhyStatEvents()
SMHBA_RegisterForTargetEvents()
HBA_RegisterForLinkEvents()
HBA_RemoveCallback()
SMHBA_GetSASPhyAttributes()
SMHBA_SendSMPPassThru()
SMHBA_GetFCPhyAttributes()
HBA_SendCTPassThruV2()
HBA_SetRNIDMgmtInfo()
HBA_GetRNIDMgmtInfo()
HBA_SendRNIDV2()
HBA_SendRPL()
HBA_SendRPS()
HBA_SendSRL()
HBA_SendLIRR()
HBA_SendRLS()
HBA_SendTEST()
HBA_SendECHO()
7. Close open HBAs by calling HBA_CloseAdapter().
8. Unload the library by calling HBA_FreeLibrary().
