RAID/SMART driver

NTDEV

Hi.
I develop driver so that driver is second for device. (I know that its not
“good”) Maybe someone now how to

  1. How to Synchronize work of all 2 drivers.
    If its only one way - to install upper filter driver what to do if filter
    driver is alredu exist.

  2. What do you think about this project? it is possible to create driver
    which will work correctly with the device?

I want to take a S.M.A.R.T. attributes like tempreture of each disk in RAID
array . In user mode i can’t do this. Maybe you have any idea about it?

2nd driver for device - generally that would be a filter driver. You may
have multiple upper/lower filter drivers for any device. If there is
already an upper filter (or filters) then just append or prepend your
filter to the existing list.

You cannot synchronize operation of other drivers other than by holding
off IO requests to lower devices.

How are you going to access individual physical disks in a raid set?
Generally this is vendor dependent.

What adapter are you using? Is it an LSI 1020/1030? If so then you can send
an IOCTL_SCSI_MINIPORT with a SCSI IO RAID PASSTHROUGH request, but you
will have to go to LSI to get the header files and docs you need.

Oh, and incase I was unclear … you don’t need a kernel driver to send the
IOCTL_SCSI_MINIPORT. You can do it from an application.

It would be my guess that much the same facility exists in other RAID
controllers, but you will have to go to the manufactuer of the controller
for specifics on how to do that.

To Roddy, Mark
I use PIO. ATA registers. Disable interrupt on RAID controller and send. But its work only if disks are in rest.
To Gary Little
I try to do this with Tecram T-822 and Fastrak TX4000 and Fastrak TX4000
Thanks to all. I ll try to do it. Don’t close this topic please.
