removable disk Mapping for scsi driver

OSR_Community_User · January 16, 2002, 12:01am

Hi,
I have to write a scsi miniport driver which
actually communicates through the TCP/IP stack
and not the actual HBA.

I have lots of doubts regarding the scsi
miniport driver. I wrote a small scsi miniport
driver , the AdapterInterfaceType which i
specified was PCIBus and just printk’s in all the

routines except for the minimal initializations.
I was able to load the driver successfully.

My problem is How to send requests to the
miniport driver?. Is it possible to map a
removable disk(drive letter) so that I/O system
sends requests to the SCSI class driver which
inturn send requests to my scsi miniport driver.

What should be the interface type to be
specified??

Please send some inputs to this.

regards,
Murali

You use SPTI and/or an IoCtl such as IOCTL_SCSI_MINIPORT.

Hi Murali,

You can check www.cooldev.com for KoolStorage product. That’s exactly what
you want. Mapping removable drive over TCP. Even if you’ll choose different
model (not SCSI miniport) you can experiment with our software (source code
partially included in demo version) for free. I’d recomment personally
developing the core storage driver as monolithic scsi port not miniport
(tons of reasons skipped, you can just search this arhcive).

Regards,
Anton

Hi,

I think sending private SCSI command to device is much better idea - the
code will be:

More portable (IOCTL_SCSI_MINIPORT IOCTL support under Windows
95/98/ME?)
Does not rely on SCSI miniport model (you can use full port driver and
the command will be still devlivered to your LUN)

Anton

What revision of the iSCSI specification is you code compliant with?

Is this absolutely required for a free demo?
