HBA_GetAdapterPortAttributes(3HBAAPI) Common Fibre Channel HBA Information Library Functions HBA_GetAdapterPortAttributes(3HBAAPI)NAMEHBA_GetAdapterPortAttributes, HBA_GetDiscoveredPortAttributes, HBA_GetPortAttributesByWWN - retrieve Fibre Channel port attributes for a specific deviceSYNOPSIScc [ flag... ] file... -lHBAAPI [ library... ] #include <hbaapi.h> HBA_STATUS HBA_GetAdapterPortAttributes(HBA_HANDLE handle, HBA_UINT32 portindex, HBA_PORTATTRIBUTES *portattributes); HBA_STATUS HBA_GetDiscoveredPortAttributes(HBA_HANDLE handle, HBA_UINT32 portindex, HBA_UINT32 discoveredportindex, HBA_PORTATTRIBUTES *portattributes); HBA_STATUS HBA_GetPortAttributesByWWN(HBA_HANDLE handle, HBA_WWN PortWWN, HBA_PORTATTRIBUTES *portattributes);PARAMETERShandle an open handle returned from HBA_OpenAdapter(3HBAAPI) portindex the index of a specific port on the HBA as returned by a call to HBA_GetAdapterAttributes(3HBAAPI). The maximum value specified should be (HBA_ADAPTERATTRIBUTES.NumberOfPorts - 1). portattributes a pointer to an HBA_PORTATTRIBUTES structure. Upon successful completion, this structure contains the specified port attributes. discoveredportindex the index of a specific discovered port on the HBA as returned by HBA_GetAdapterPortAttributes(3HBAAPI). The maximum value specified should be (HBA_PORTATTRIBUTES.NumberOfDiscoveredPorts - 1). PortWWN the port WWN of the device for which port attributes are retrieved.DESCRIPTIONThe HBA_GetAdapterPortAttributes() function retrieves Port Attributes for a specific port on the HBA. The HBA_GetDiscoveredPortAttributes() function retrieves Port Attributes for a specific discovered device connected to the HBA. The HBA_GetPortAttributesByWWN() function retrieves Port Attributes for a specific device based on the PortWWN argument.RETURN VALUESUpon successful completion, HBA_STATUS_OK is returned. Otherwise, an error value is returned from the underlying VSL and the values in hbaattributes are undefined.ERRORSSee libhbaapi(3LIB) for general error status values.EXAMPLESExample 1 Retrieve the port attributes for each port on the HBA. The following example retrieves the port attributes for each port on the HBA. for (hbaPort = 0; hbaPort < hbaAttrs.NumberOfPorts; hbaPort++) { if ((status = HBA_GetAdapterPortAttributes(handle, hbaPort, &hbaPortAttrs)) != HBA_STATUS_OK) { fprintf(stderr, "Unable to get adapter port %d " "attributes for HBA %d with name "%s". ", hbaPort, hbaCount, adaptername); HBA_CloseAdapter(handle); continue; } memcpy(&wwn, hbaPortAttrs.PortWWN.wwn, sizeof (wwn)); printf(" Port %d: WWN=%016llx ", hbaPort, wwn); /* ... */ } Example 2 Retrieve the discovered port target attributes for each discovered target port on the HBA. The following example retrieves the discovered port target attributes for each discovered target port on the HBA. for (discPort = 0; discPort < hbaPortAttrs.NumberofDiscoveredPorts; discPort++) { if ((status = HBA_GetDiscoveredPortAttributes( handle, hbaPort, discPort, &discPortAttrs)) != HBA_STATUS_OK) { fprintf(stderr, "Unable to get " "discovered port %d attributes for " "HBA %d with name "%s". ", discPort, hbaCount, adaptername); continue; } memcpy(&wwn, discPortAttrs.PortWWN.wwn, sizeof (wwn)); printf(" Discovered Port %d: WWN=%016llx ", discPort, wwn); /* ... */ }ATTRIBUTESSee attributes(5) for descriptions of the following attributes: +-----------------------------+-------------------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-------------------------------------+ |Interface Stability |Standard: FC-MI 1.92 (API version 1) | +-----------------------------+-------------------------------------+ | |Standard: FC-HBA Version 4 (API ver- | | |sion 2) | +-----------------------------+-------------------------------------+ |MT-Level |Safe | +-----------------------------+-------------------------------------+SEE ALSOHBA_GetAdapterPortAttributes(3HBAAPI), HBA_OpenAdapter(3HBAAPI), libhbaapi(3LIB), attributes(5) T11 FC-MI Specification SunOS 5.11 1 Sep 2003 HBA_GetAdapterPortAttributes(3HBAAPI)
