I did a quick look into hpcisss2.sys

Such driver is CSMI based and it recognizes CC_CSMI_SAS_STP_PASSTHRU 
control code in CSMI_SAS_SIGNATURE group.

But it also implements proprietary access control as described in 
paragraph 5 of:
> http://www.t10.org/ftp/t10/document.04/04-284r0.pdf

The CC_CSMI_SAS_STP_PASSTHRU requires CSMI=Full access while default is 
CSMI=Limited - so the CC_CSMI_SAS_STP_PASSTHRU requests are refused.

There's a chance that smartmontools will work, using CSMI (-d csmi) 
method - if the driver will be reconfigured in registry to allow full 
access.

Sorry, I have no such hardware, so I can't test by self.

I claimed, I did just quick look into binary driver = so I can be wrong.

Even if it will work, I feel no responsibility for possible security 
consequences of driver running in CSMI=Full mode. Nor for other 
consequences it may have.
