enumerate children disk PDOs of a parent controller;

In my driver I need to know all the disks PDOs enumerated by a specific controller. I have parent controller’s FDO/PDO available?

Thanks.

You can do this in user mode, not kernel

ok. I need to identify a particular disk (in kernel mode). Do you have any suggestions how can I do that? I tried using Pnp notification (GUID_DEVINTERFACE_STORAGEPORT) to get notify upon the arrival of the disks and then send identify to it (using IOCTL_SCSI_MINIPORT + SMART_RCV_DRIVE_DATA) to check if it is the interesting one but I received 0xC0000010L status. Any suggestions? Thanks.

GUID_DEVINTERFACE_STORAGEPORT would be the storage port FDO device interface, if you want disks, have you used GUID_DEVINTERFACE_DISK?

The disks I’m interested in do not have a class driver so I cannot use GUID_DEVINTERFACE_DISK. [Thanks for the quick reply]

Well you need to find out what devinterface the non class driver enables for the disks and subscribe to that
