Hi All,
How do i get event for *all disks claimed completion by disk.sys driver*
If your aware about this event. Pl. let me know details about this.
Thanks in advance,
Regards,
Pravin G
There is no such event, with hot plug, etc the result would be never.
As a disk is recognized a full stack is typically built, so even if
there was such an event it is worthless.

Don,
I am writing a program to install MPIO driver & DSMs and embedding it in to
product installer.
Product installer executes my program at the end of install procedure and
ask for system reboot.
but after system reboot it ask to reboot it again.
I analyzed this scenario and i found that while installing MPIO driver and
DSMs my program returns immediately after installation of MPIO driver and
DSMs. but after this disk configuration activity takes place where system
spend some time and ask for second reboot to activate new devices.
Disk configuration activity is as follows:
-
All available SCSI disks claimed by the MPIO driver(mpdev.sys) based on
comparing disks Hardware Id and compatible Id for available DSMs. With this
all SCSI disks become MPIO disks with Hardware Id ‘gendisk’. -
Now disk.sys is looking for disks available on system who is having
Hardware Id ‘gendisk’. After conformation of Hardware Id Disk driver starts
claiming those disks with this all disks are ready for OS to use.
So, now i want to monitor and control this activity in my program. so that i
can avoid second reboot.
Pl. guide me to achieve this.
Thanks,
Regards,
Pravin G

The second reboot request after modifying the storage stack is
unavoidable if you have inserted your drivers into the boot or paging
or dump path. It might even be unavoidable for any mounted volume.

Hello Mark,
It is asking for second reboot because my program is not ensuring finish of
device configuration activity before first reboot.
if somehow i am able to wait on event for device install completion
activity, will confirm that storage device stack has been modified before
first reboot then i can shift control to main installer. This will work with
only one reboot.
but i want to get that event…!!!
Thanks,
Regards,

You could monitor but how could you control this?
I got the similar situation. We had our disk class driver which creates a virtual disk. We had one reboot when a system installed a disk class driver and the second reboot when the system mounted the virtual disk. It happened only one time on clean machine which didn’t have our disk class driver. We just didn’t pay attention to this because it would not worth to solve the problem.

This effect was certainly true for W2K3 vintage releases. I think it was
also true for 2008 server.
