Stor miniport: StorSynchronizeFullDuplex or StorSynchronizeHalfDuplex ?

Hi ,

The structure “PORT_CONFIGURATION_INFORMATION (Storport)” has a variable "SynchronizationModel ". And this variable can be set as “StorSynchronizeFullDuplex” or “StorSynchronizeHalfDuplex” . Now when “StorSynchronizeHalfDuplex” is set, my stor miniport driver works correctly but slowly. And When “StorSynchronizeFullDuplex” is set, my stor miniport driver runs rapidly but “stops” after some time(a lot of “SRB_FUNCTION_RESET_LOGICAL_UNIT” commands are repeatedly sent to my stor miniport driver ).

I am so confused that what is the essential difference between “StorSynchronizeFullDuplex” and “StorSynchronizeHalfDuplex” ? And what can I do ?

Thank you!

Hi,
While my stor miniport driver is set as “StorSynchronizeFullDuplex” , Longhorn/Vista sometimes can be installed on my raid, sometimes can’t; sometimes will “stop”, sometimes will crash. And on some mainboards, Longhorn/Vista can be always installed, and on some other mainboards, Longhorn/Vista nearly can’t be installed everytime.
Oh! I am suffering at this.
