NAME

HBAAPI - Fibre Channel Storage Network Industry Association Host Bus Adapter API

DESCRIPTION

The Common Host Bus Adapter Application Programming Interface (HBA API) provides a con-

sistent HBA standard interface for accessing information in a Fibre Channel (FC) Storage Area

Network (SAN) that is implemented across vendors as a standard ’C’ API supported by vendor-

speciﬁc library instances.

This API library is thread-safe. However, note that threads must not be cancelled when the exe-

cution is in the API.

The following functions are available in the API for managing a Fibre Channel HBA:

• General Vendor-Implemented Functions

— HBA_GetVersion( );

— HBA_LoadLibrary( );

— HBA_FreeLibrary( );

— HBA_GetNumberOfAdapters( );

— HBA_GetAdapterName( );

— HBA_OpenAdapter( );

— HBA_CloseAdapter( );

• Informational Functions

— HBAGetAdapterAttributes( );

— HBAGetAdapterPortAttributes( );

— HBAGetPortStatistics( );

— HBAGetDiscoveredPortAttributes();

• FCP Information Functions

— HBAGetFcpTargetMapping( );

• Control Functions

— HBARefreshInformation( );

This API is exposed to upper level applications to control storage area network (SAN) functions.

For detailed information about structures used, see the Fibre Channel - Methodologies for Inter-

connects (FC-MI) Revision 1.6 Annexure A by the Storage Network Industry Association

(SNIA).

NOTES

The functions in this API are available in a statically-linked archive library at

usr/lib/libcmnapi.a. For more infomation about using archives, see the eld Manual.
