Hi all,
Can someone give me lead to implementing a scsi target mode driver in
NT/win2k.
Thanks,
Jeyaram

I’ve successfully implemented a SCSI Target Mode driver in NT/2K. First
you need a SCSI/Fibre Channel adapter that can support it and the low-level
code to drive it. Then you wrap around that a SCSI miniport driver with a
private interface that is architected to support SCSI Target Mode. You
need to notify upper layers when a command is received, and the NT I/O
driver stack is not architected to do this. I then went ahead and created
a user-mode DLL with an ASPI-like interface into the kernel-mode driver for
the purpose of exporting the SCSI Target Mode functionality to other user
apps. It works great. If interested, call or e-mail me for more details.
Thanks,
Don

Hi, it is very nice for me to find a guru in this Fibre Channel Adapter
driver development. I need to write a Fibre Channel Adapter or some kind of
HBA(Host Bus Adapter) driver. But now I am not very familiar with this
field. Can you give me some advice on how to write this kind of drivers?
Where can I find some materials about this? Does it need some background
knowledge? I have driver development experience for some kind of parallel
port device and WDM driver(USB). Or can you give me a sample example? In
order to develop a Fibre Channel Adapter or HBA driver I need to know
something about NDIS driver?
Thank you very much. I really appreciate your help.
Michael

Much of that will depend upon the Fibre channel controller that you are
using. If you have a Qlogic 2x00 family then all you need to do in is to use
the drivers provided by Qlogic for SCSI and TCP/IP, or use the boards that
we manufacturer based on the Qlogic adapter and our drivers for non-SCSI
mini-port usages such as peer to peer.

In the Win2K DDK there are sample SCSI miniport drivers
under src\storage\miniport. Similarly, there are NDIS
miniport samples.
Modifying this (i.e., using it as a skeleton) to work with your adapter would allow you to initiate SCSI commands to disk
devices, etc.
On NT4 and I think Win2K, NDIS was for networking, and you’d write NDIS miniports, and Microsoft did not have a story that would
allow you to
use the same adapter for both SCSI disks and say TCP/IP, even though the
hardware didn’t prevent it. There was a rumor a long time ago that
XP would allow one miniport driver to be used for both purposes, but I have no
info on whether this happened.
