I implemented a driver which emulated a SCSI disk with a remote file. To
achieve PnP, A bus driver was added.
When the connection has been set up, everything is fine.
However, in the process of handling READ command(suppose I am reading the
MP3 file on the virtual disk),
once the connection is failed, I send EJECT command directly to the bus
driver. It shows error that I cannot do that.
How can I handle this kind of exception?
Any reply will be appreciated.

I would add a call to your bus driver that would tell it to make the PDO go
away. Your bus driver would then do a IoInvalidateDeviceRelations and
indicate the PDO is no longer present. That way remove handling would take
place…
