<li><b>Can I monitor ATA disks behind SCSI RAID controllers?</b>
<li><a name="FAQ-RAID"></a><b>Can I monitor disks behind RAID controllers?</b>
<p>
From release 5.1-18, smartmontools fully supports 3ware SCSI RAID
controllers that use ATA disks internally. To pass commands through
the 3ware controller, use the smartmontools <b>-d 3ware,N</b> option
or Directive.
</p>
<p>
3ware Linux device drivers (<tt>3w-xxxx</tt>) versions <b>1.02.00.036</b>
and earlier do not return the SMART HEALTH STATUS (smartmontools
<b>-H</b>) of the disks. In addition, the ENABLE AUTOMATIC OFFLINE and
ENABLE ATTRIBUTE AUTOSAVE commands (smartmontools <b>-o on</b> and
<b>-S on</b>) can not be passed through the driver to the disks.
Later driver versions support <i>all</i> of these commands. You may:
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.
</p>
<ul>
<li>use version <b>1.02.00.037</b> or greater of the <tt>3w-xxxx</tt> driver, or</li>
<li><a href="3w-xxxx.txt">patch</a> earlier 3ware <tt>3w-xxxx</tt> drivers so that
these commands reach the disks, or</li>
<li> use an <b>unpatched</b> earlier <tt>3w-xxxx</tt> driver (which won't pass these
commands to the disks but will instead print
harmless warning messages to SYSLOG).</li>
<li><p>
3ware RAID controllers are supported on Linux since smartmontools release 5.1-18.
Support for char devices /dev/tw* was added in release 5.33.
</p></li>
<li><p>
3ware support on FreeBSD is available since release 5.33, multiple controller and
char device support was added in release 5.36.

3ware 9000 support for Windows was added 2006-09-27, the corresponding 3ware

<p>
To see if your system's <tt>3w-xxxx</tt> driver has been patched, give the
command:<br/>
<tt>smartctl -H -S on -o on -d 3ware,? /dev/sd?</tt>
<br/>
If you
have an unpatched kernel, you'll see warning messages prompting you to
patch the kernel.</p>
<p>
The 3ware <tt>3w-xxxx</tt> version 1.02.00.037 driver first appeared
in kernel version 2.6.0-test5-bk11 on 24 September 2003 and in kernel
version 2.4.23-bk2 on 3 December 2003. It was officially released on
the 3ware web site on December 19, 2003 as part of their
driver/firmware/utility package version 7.7.0.
The recent additions will appear in upcoming release 5.37.
</p>
<p>
Note (added 29 July 2004): starting with smartmontools (experimental)
release 5.33, one can also access SMART data from drives behind 3ware
controllers using the (character) devices /dev/twe0-15. This should
work correctly even with older versions of the 3w-xxxx driver. One can
also access SMART data from drives behind 3ware 9000-series
controllers (3w-9xxx driver) using the (character) devices
/dev/twa0-15.
