It most certainly will allow you to paste code into your question, so you need to learn how. After this call, the HBA miniport driver owns the request and is expected to complete it. I ahve the source only and no debug environment. A miniport driver that calls ScsiPortInitialize more than once should check the value returned by ScsiPortInitialize at each call and save the lowest value for all its calls. Join Date May Posts 5. The Storport-miniport driver interface is designed to be as similar to the SCSI Port-miniport driver interface as possible, in order to facilitate the adaptation of SCSI Port miniport drivers to work with the Storport driver.

Bus enumeration is time-consuming and ties up the bus, so a miniport driver should not send this notification unnecessarily. No real difference, and actually better than the MS driver. storprt
Google was no help. Plz whatever you explain ,explain in detail. But it did not work. These differences, discussed in the remainder of this section, provide the advanced functionality of Storport that sciport vendor miniport drivers and adapter hardware to function more effectively.
Though I am not a expert in windows programming, please ensure the following.

ScsiPortCompleteRequest can be called to complete outstanding requests after a bus reset, a device reset, or an abort, rather than calling ScsiPortNotification for each outstanding request individually.
The time now is I believe you have included at least one of these header files: WIll continue to look. In this callback, the miniport driver reenables interrupts on the HBA. HwScsiResetBus can be called even if the miniport driver is not ready for another request.
Miniport drivers of HBAs that do not generate interrupts do not have this routine. The miniport driver should complete all pending requests and must scskport the given bus. In the Marvell MV91xx driver package there are two folders, storport and miniport. The Betaeen routine must return the lowest value when it returns control to the system. Call ScsiPortNotification with the request to be deferred and a notification type of RequestComplete. At least they don’t give a BSOD coming out of sleep like some previous versions.
Notes on Windows SCSI Miniport Driver
All SCSI miniport drivers must have some of the routines described in this section. For a Plug and Play miniport driver, the port driver calls HwScsiFindAdapter when anf Plug and Play manager has diffwrence an adapter for that miniport driver. Note that the diagram shows relative time, not actual time units. After this call, the HBA miniport driver owns the request and is expected to complete it.
So it seems that the Storport driver in W2k3 is more reliable and performant and is also new and maybe not yet tested in all environments. Indicates that a target device might have been added or removed from a dynamic bus. I tried to warp dbgprint in another method.
It is compiled on W2k3 checked x86 using build utility. Join Date May Posts 5.
What’s the difference between SCSIport and Storpor – Hewlett Packard Enterprise Community
storort This actually will earn some respect to the visitor when they read such a good info. I will post again if I come across it. Are your switches zoned so that only one hba on your server can see only 1 storage port OR tape port? Data transfers are performed by the hardware itself using Direct Memory Access or DMA without operating system intervention.
