Hi,
any ideas on best way to switch IRPs from a removed disk device (typically a
surprise removal, or failure), and redirect them to a valid device? I have
an upper filter driver that can redirect to a different device during I/Os,
given that both devices are in valid state, but when I pull the cable on
primary device, I want to switch the I/Os that were meant for it to the
valid secondary device, but the PNP mgr has a different idea. 
What this comes down to is either faking out the PNP mgr, or finding an
“approved” method.
This is on win2k.
thanks
andy
