Virtual disk with a bus enumerator (SRB_FUNCTION_CLAIM_DEVICE) ?

OSR_Community_User · July 2, 2001, 10:05pm

I have a bus enumerator based on the Toaster sample.
I return ?DETECTED\FakeDisk? for deviceID, and ?GenDisk? for
CompatibleId. It works fine.
The Pnp manager finds my fake disk drive add to the device list, and
send me an
SRB_FUNCTION_CLAIM_DEVICE message (IRP_MJ_SCSI). I just return a
STATUS_SUCCESS status, and then the Pnp manager says I have to reboot
the system. That means I don?t get more SRB_FUNCTIONs. I checked the
disk class driver source code in the DDK, and seems it doesn?t need more
response for CLAIM_DEVICE, just the status.

How can I avoid the reboot?

As I remember Anton Kolomyeytsev asked similar question a few days ago,
but I couldn?t find the answers.

Regards,

Zoltan

Ps:

Anton,

Maybe you can help me with this problem.

Hi,

You have to implement a couple of IOCTLs in your code as well. At least
IOCTL_STORAGE_QUERY_PROPERTY. See the source of the disk class driver in
DDK for this. Other IOCTLs are optional (as IOCTL_SCSI_GET_ADDRESS,
IOCTL_DISK_GET_DRIVE_GEOMETRY etc).
