HBA_GetAdapterPortAttributes(3HBAAPI)         Common Fibre Channel HBA Information Library Functions         HBA_GetAdapterPortAttributes(3HBAAPI)

NAME

       HBA_GetAdapterPortAttributes,  HBA_GetDiscoveredPortAttributes,  HBA_GetPortAttributesByWWN  - retrieve Fibre Channel port attributes for a
       specific device

SYNOPSIS

       cc [ 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);

PARAMETERS

       handle          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.

       discoveredportinthe 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.

DESCRIPTION

       The 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 VALUES

       Upon  successful  completion,  HBA_STATUS_OK  is  returned. Otherwise, an error value is returned from the underlying VSL and the values in
       hbaattributes are undefined.

ERRORS

       See libhbaapi(3LIB) for general error status values.

EXAMPLES

       Example 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);

           /* ... */
       }
