Operating Systems Solaris Sense key unit attention & iostat hardware and transport errors on SAN disks Post 302836335 by DukeNuke2 on Wednesday 24th of July 2013 03:03:11 AM

It could be the whole way of transport... From HBA to the transceiver over the cables to the other end of the system. it can also be a hardware error on the HBA itself. Also there can be a faulty device which may cause bus resets and therfore a rescan of the bus all the time.

The first thing I would try is to change two transceivers (from two HBAs; if you have) and see if the error is going with the transceiver or staying on the same controller.

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

NAME
HBA_RefreshInformation, HBA_RefreshAdapterConfiguration - refresh information for a specific HBA SYNOPSIS
cc [ flag... ] file... -lHBAAPI [ library... ] #include <hbaapi.h> void HBA_RefreshInformation(HBA_HANDLE handle); void HBA_RefreshAdapterConfiguration(void); PARAMETERS
handle an open handle returned from HBA_OpenAdapter(3HBAAPI) DESCRIPTION
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_ILLE- GAL_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. ATTRIBUTES
