HBA_RefreshInformation, HBA_RefreshAdapterConfiguration - refresh information for a specific HBA
cc [ flag… ] file… –lHBAAPI [ library… ] #include <hbaapi.h> void HBA_RefreshInformation(HBA_HANDLE handle);
an open handle returned from HBA_OpenAdapter(3HBAAPI)
The HBA_RefreshInformation() function requests that the underlying VSL reload all information about the given HBA. This function should be called whenever any function returns HBA_STATUS_ERROR_STALE_DATA, or if an index that was previously valid returns HBA_STATUS_ERROR_ILLEGAL_INDEX. Because the underlying VSL can reset all indexes relating to the HBA, all old index values must be discarded by the caller.
The HBA_RefreshAdapterConfiguration() function updates information about the HBAs present on the system. This function does not change any of the relationships between the HBA API and adapters that have not been reconfigured. HBA handles continue to refer to the same HBA even if it is no longer installed. The HBA name or index assigned by the library remains assigned to the same HBA even if it has been removed and reinstalled, as long as the bus position, WWN, and OS device have not changed. Adapter that have been removed and not replaced cannot have their HBA handles, HBA names, and HBA indexes reassigned. Calls to these adapters will generate HBA_STATUS_ERROR_UNAVAILABLE.
