All miniport drivers must have a HwScsiStartIo routine. But I have solved this problem. The SCSI port driver will manage all required bus-reset delays. But it did not work. While this callback runs, it cannot be preempted by an interrupt except from a device with a higher priority interrupt than the HBA. Thank u for reply. Indicates that a target device might have been added or removed from a dynamic bus.

windows – SCSI port vs storport – Stack Overflow
Given the inherent limitations of using SCSIport with high performance adapters for which it was not designed, Microsoft has developed a new port driver, Storport. After this notification, the miniport driver is still responsible for completing any active requests.

Join Date May Posts Bus enumeration is time-consuming and ties up the bus, so a miniport driver should not send this notification unnecessarily.
Indicates the miniport driver is ready for another request to a target that is not currently busy. This is not allowing me copy paste the scaiport.
Notes on Windows SCSI Miniport Driver
Post as a guest Name. In this callback, the miniport driver reenables interrupts on the HBA.
If this value is set, ScsiPortNotification requires two additional parameters: WIll continue to look. This notification should be sent by the miniport driver as soon as the driver is ready for another request. Leave a Reply Cancel reply Your email address will not be published.
Marvell MV91xx SATA driver – storport or miniport?
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. While this callback runs, it cannot be preempted by an interrupt except from a device with a higher priority interrupt than the HBA. This value should be used only if the HBA can queue multiple requests nad support auto-request sense or tagged queuing.
Google was storporr help. The difference is in the way the driver interacts with Windows. As soon as it receives the initial request for a target peripheral, the operating system-specific port driver calls the HwScsiStartIo routine with an input SRB. When you go to update the driver in dev mgr, specifically which file do you point it to?
I ahve the source differfnce and no debug environment. One thing to look at also is how your Fabric Zoning is configured.
These limitations have been overcome with the development of Storport, the new device driver designed to supplement SCSIport on Windows Server and beyond. There’s an indepth document from Microsoft found here: That betweeh one of the docs I was referring to.
If you’re going to use StackOverflow, you need to learn how to post. In the Marvell MV91xx driver package there are two folders, storport and miniport.
