NT Fake out SCSI Miniport driver

I'm looking for information on, or sample code for, a fake out NT scsi miniport driver. I need to know how to make it look like I have a bogus device hooked up to a bogus HBA. I took the aha154x DDK sample and have it looking like \Device\ScsiPort2 to NT, but I need to know how to get NT to think there's a device attached that it can talk to. How do I configure HW_INITIALIZATION_DATA, and how do I handle callbacks for the various routines to and from the scsi port driver. Thanks. Chuck xxxxx@usa.net PS - My DebugPrint()s don't show up on windbg. --

RE: NT Fake out SCSI Miniport driver

NT (SCSIPORT) discovers LUNs on the HBA by sending SCSI inquiry and/or report-LUNs commands to potential SCSI addresses. These are sent to your miniport as SRBs via HwStartIo. You just need to mock valid device responses to these commands for one such address (LUN should be zero, as SCSIPORT won't discover non-zero LUNs if there is no response on LUN zero). ----------------------------------------------------------------------- Dave Cox Hewlett-Packard Co.

RE: NT Fake out SCSI Miniport driver

Hi, I think ATAPI will be the best one to start with. Regarding the DebugPrint's you need to change the export variable ScsiDebug of SCSIPort to 1, 2 or 3. If you use DebugPrint((0, "....")); it will be displayed in WinDebug without changing the SCSIDebug variable. Ofcourse you need to copy the debug version of SCSIPort.sys to see all the debug messages anyway. Syam. -----Original Message----- From: Chuck R [mailto:xxxxx@usa.net] Sent: Monday, June 26, 2000 6:51 PM To: NT Developers Interest List Subject: [ntdev] NT Fake out SCSI Miniport driver I'm looking for information on, or sample code for, a fake out NT scsi miniport driver.

RE: NT Fake out SCSI Miniport driver

A really nice solution to setting ScsiDebug automatically is to place the following registry value: HKLM\system\currentcontrolset\services\(scsi miniport driver name)\device\ScsiDebug:REG_DWORD You still need to be using the checked version of scsiport of course.

Re: NT Fake out SCSI Miniport driver

The first step would be to let scsiport know that a device is attached to the controller. ScsiPort will only create Device Objects when SP_RETURN_FOUND is returned to a call to your HwFindAdapter routine. You also need to fill in the correct values in the structure PORT_CONFIGURATION_INFORMATION that is returned to the scsiport. Good Luck!
