I can't believe how much this sucks.
Workaround 1 is what i'd really love, I also discovered the lack of
documentation. Also, a list of all the EventID numbers (with
descriptions)that it puts in the Windows application log would be nice
(since there isn't a red or yellow event that occours if you just pull out a
drive..), so that I know what event codes our event monitoring software
should send an email to me on. I was never able to get an answer from Intel
on this one. They just said they didn't have a list on that, with the excuse
that the info the Manager can report is supposed to be more detailed (though
I didn't try calling back several times to get different peoples answers)...
clearly I need the phone extension of the developers of the
application/driver for that. :( :( :(
Unfortunatley, the other options are not going to work:
- I need to know the temp of the actual drives.
- I'm not sure my boss would go for installing another drive (of the same
model, since I've seen over 10 degrees of difference in drive temperatures
of different models sitting right next to each other) in each of these
machines, so that we know the temp of the drives :) It would also mean
getting access to all the machines in the off hours... which don't have an
IT person at the locations.
Thanks for all the suggestions I hadn't thought of...
I guess I'll call Intel a few more times to try and root out as much info as
I can... then DEFINATELY report back here with whatever I find out.

So, the docs say something along the lines of... "Third party
applications are not able to monitor the S.M.A.R.T settings (such as
drive temperature), but the storage manager software will notify you if a
problem comes up".
So..... what if I want to just look at some smart values.... say, the
temperature? Because I run some systems in remote locations using IMST in
RAID1... and they don't have air-conditioning on at night, so I am
wanting to monitor the drives temperature, in case I need to rectify the
cooling situation at all.
Does anyone know of a tool to get these values? Or some way to get them
from the Storage Manager or something?
This is an example of Intel's view on the subject.
http://www.intel.com/support/chipsets/imsm/sb/cs-015002.htm
"Can't view S.M.A.R.T. values of hard drive after setting up RAID
Intel Matrix Storage Manager supports S.M.A.R.T.; however, once a
RAID volume is created using the Intel Matrix Storage Manager, the
S.M.A.R.T. values of the hard drives can no longer be viewed by third
party software utilities that read these values.
This is a known issue. While S.M.A.R.T. values cannot be viewed by
third party software utilities, they are still reported as S.M.A.R.T.
alerts by the Intel Matrix Storage Manager tray alert and the
Intel Matrix Storage Console."
Possible workarounds.
1) Figure out how to use "tray alert" ? I can't find a decent manual with
details.
Manual70.pdf from Intel doesn't say.
2) Use a utility that can monitor the "motherboard temperature" readout
provided by the Super I/O hardware monitor interface ? The motherboard
temperature may reflect changes in room temp. This isn't always going
to work in an absolute sense, since some motherboards have picked a
"hot spot" for the location of the sensor. Take readings from all
your computers, when air conditioning is known to be functional, and
then note any temps which shoot past these norms. Even if the sensor
reads "60C", if the room gets 10C hotter, the sensor should read "70C",
and you know there is a delta of 10C present in the room. Even if the
motherboard is not actually at 70C. The sensor may only be good enough
for relative measurement. (The motherboard sensor on mine works
properly,
and is likely a separate thermistor. I also have a room temperature
sensor connected to a spare header provided by the motherboard. Not
many motherboards provide that.)
3) Install a separate disk, not part of any array. Then a SMART utility
can read that disk.
There is a FAQ here, where I first read about the "passthru" issue for
pseudo-SCSI interfaces and using SMART.
"Can I monitor disks behind RAID controllers?"
http://web.archive.org/web/20080110092056/http://smartmontools.sourceforge.net/
"RAID controllers typically simulate a (logical) disk for each array of
(physical) disks to the OS. Access to SMART functionality relies on
ATA
or SCSI pass through I/O controls providing direct access to each
physical
disk. But the standard I/O controls available are usually not designed
to
make this distinction between logical and physical disks. Therefore,
smartmontools has to use vendor specific I/O controls. Support for
disks
behind RAID controllers is highly dependent on both platform and
controller type."
