Hi Anand,
Your controller only supports HDD right? If so, I don’t think you ever will
receive SCSIOP_START_STOP_UNIT. You only have SRB_SHUT_DOWN in some cases.

Hi Vu,
I have created Logical drives on the controllers.
Thanks,
Gurpreet

Hi,
You normally receive only 1 SRB_SHUT_DOWN per your logical device, unless it
is a boot device. You will not receive any more requests after this SRB.
If 1 of your logical devices is a boot device, you will have multiple
SRB_SHUT_DOWN from the OS to this device (Normally 2). Just treat the
SRB_SHUT_DOWN as a normal request then you should be covered in all cases.
Note: You will not receive the SRB_SHUT_DOWN, or any SRB_FLUSH_CACHE if
your logical device has no valid partitions. Moreover, if you have no
logical data on the device, who cares if they were shut down improperly
right! I think this is why MS does not send you any flush cache or shut
down CMD to the logical devices that do not have valid partitions.
Does your controller supports ATAPI devices also???

Hi Vu,
I dont think you have a way to tell in the Miniport
driver that the logical drive is a boot drive.
Moreover one can create a partition on the logical
drive.
DDK tells that SRB_FUNCTION_SHUTDOWN should not
considered as the last call as I can get multiple of
it ( at times more than 2).
I would push this question to MS too to check their
response.
We dont support ATAPI devices for the particular
controller I am using.
Thanks,
Gurpreet
