Hello,
I am experiencing a problem sending private IOCTL_SCSI_MINIPORT when no
drives are attached. This interface is for our management software to
create/delete arrays. At one point there won’t be any arrays at all. It
seems like the scsiport driver is blocking the IOCTL_SCSI_MINIPORT. Is there
a work around for such a situation?
Thanks for your help,
Shakeel.
Check the Archives, this question was asked sometime back …
If you are on Win2k3, this link should help (check out
CreateInitiatorLU)
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/storag
e/hh/storage/02mnport_8tgn.asp)
I guess this is not supported on Win2k, and you will probably need to
create a virtual disk (pseudo-LUN) in your miniport and handle all
inquiry and other SCSI commands to it.

No, this is a known SCSIPORT issue. Create a fake LUN on your adapter to
work it around.

Thanks Max and Girish,
The fake LUN created would appear in the Device Manager. correct? I don’t
want the user to see it, how to hide the fake LUN created from the user?
Thank you,
Shakeel.

Yes.
I don’t want the user to see it
Why not? Name it like “MyAdapter Control Device” and this will be OK. To do
this, invent the proper INQUIRY for it, and list the PnP ID (based on INQUIRY)
in your INF file.
HighPoint does this for years.

And please, please, please, don’t make the virtual lun a disk type
device. Use processor or a vendor-specific type code, but not one of
the known codes.

Max,
Actually mine is miniport for a IDE controller. So, currently I set the
PORT_CONFIGURATION_INFORMATION->MaximumNumberOfTargets = 4;
PORT_CONFIGURATION_INFORMATION->MaximumNumberOfLogicalUnits = 1;
If I change the NumberOfTargets = 5, and invent the INQUIRY data for the 5th
one. Is that all I need to do? Should I need to handle other SRB requests
for this fake Target?if not, what status I should return SRB_STATUS_ERROR
for all other requests?
Max, I didn’t understand the second part, listing of PnP ID in INF file.
Presently, I am listing the PCI VENDER/DEVICE ID for the controller. Do I
need to list one for the Disk also? Sorry! for my ignorance here.
Thanks,
Shakeel.

For a fake LUN, create the driver-less INF file section (details are
documented).
The PnP ID for all SCSI devices - your fake LUN included - is built from
the INQUIRY data, and the details are documented again - the PnP docs section
about how PnP IDs are formed for well-known busses.
So - respond to INQUIRY in your fake LUN, do NOT use the disk/CD/tape
device type - use Processor - and fill INQUIRY data with some strings of yours.
Then use the same strings in the PnP ID in the INF file.
This will lead to a sane display of the fake LUN in the Device Manager. You
can use the INF file for HighPoint 370 as a reference - they use the same
approach.

And as pointed out here by Girish, please do NOT do this for Server
2003. Instead, use the CreateInitiatorLU entry in your INF. Also, set a
BusType value (default is SCSI for scsiport, Fibre for Storport).
Check the Archives, this question was asked sometime back …

There is one problem still. If you create a ‘Processor’ type device, it
throws up ‘New Hardware Found’ box for the psuedo processor type device. Is
there a way to avoid that?

Create an INF with an entry for that device which installs nothing.
