Current smartd reports send by mail only list device name (e.g. /dev/sdc) which is not enough to easily identify the problematic disk.

It will be better to add some more info to the report, e.g. something like:

The following warning/error was logged by the smartd daemon:

Device: /dev/sdc [SAT], 4 Offline uncorrectable sectors

-----------

Device Model: WDC WD20EARS-00MVWB0 Serial Number: WD-WMAZ2026xxxxx User Capacity: 2,000,398,934,016 bytes [2.00 TB]

(above is easily obtained by smartctl -i /dev/sdc |egrep "Device Model|Serial Number|User Capacity")

Hey.

On https://www.smartmontools.org/wiki/Supported_RAID-Controllers it says:

-d cciss,N /dev/cciss/cXd0

and

-d cciss,N /dev/cissX

for CCISS (HP/Compaq Smart Array Controller).

However, it seems that /dev/cciss/ is no longer present with current drivers.

But... it seems that one can simply use *any* device that is exported from that controller, e.g. /dev/sda (if that is).

Perhaps just add a note to the wiki (and other documentation) that this works just as well, which may not be immediately obvious.

Thanks, Chris.

Most of SCSI/SAS drives are supporting cache control, so it is possible to implement this functionality. This should help a lot for SAS drives behind the RAID - some of them turning off write cache if drive is not "native".

Tested on scsi, megaraid and cciss device types on Linux. It was found that cciss silently filtering MODE SELECT command, so actual values are not changed. On megaraid and direct connection everything works as expected.
