Ref: Not receiving SCSIOP_START_STOP_UNIT during Shutdown

NTDEV
1

Hi All,

I have the following queries regarding the Shutdown
handling in the Windows 2000/2003.

I am trying to use SCSIOP_START_STOP_UNIT command
targeted at the LUN (and delivered to miniport via
SRB_FUNCTION_EXECUTE_SCSI) to spin down the drives.

To receive SCSIOP_START_STOP_UNIT, I am using the
following registry entry
[install_section_name.HW] HKR, “ScsiPort”,
“NeedsSystemShutdownNotification”, 0x00010001, 1

But I have seen that I am still not receiving
SCSIOP_START_STOP_UNIT command during shutdown even
after adding this entry to the registry.

Does anyone has faced this issue.

Thanks,
Gurpreet

Hi Gurpreet,

Do you see a SRB_FUNCTION_SHUTDOWN request coming in at shutdown.
Unless you can directly process the PNP power IRP’s, which is the case
for SCSI miniports, then this is your next best chance to spin down your
drives.

MKE.

Hi,

I believe you receive multiple shutdowns commands
(SRB_FUNCTION_SHUTDOWN) during shutdown, so basically
no way to determine which is the last one.

Thanks,
Gurpreet
