## List of raid systems and how to monitor them
### FreeBSD gmirror software raid

<br />mpt based devices can be monitored under Linux with the kernel module "mptctl" and the <a title="The term &quot;FOSS&quot;" href="../../documentations/foss/the-term-foss">FOSS</a> tool "<a href="http://www.drugphish.ch/~ratz/mpt-status/">mpt-status</a>". There seems to be no support under FreeBSD available currently.

<br />This driver is used for most HP / Compaq controllers and is (afaik) found in almost all modern SAS/SATA systems provided by HP. As described in http://www.unixadmintalk.com/f41/monitoring-raid-arrays-51889/, you can monitor it via <b>camcontrol</b>:<br /><br />
<pre># camcontrol inquiry da0<br />pass0: &lt;COMPAQ RAID 1 VOLUME OK&gt; Fixed Direct Access SCSI-0 device<br />pass0: 135.168MB/s transfers<br /></pre>
<p>(This is untested by me, just found it on the net). On <a href="http://lists.freebsd.org/pipermail/freebsd-proliant/2006-October/000169.html">http://lists.freebsd.org/pipermail/freebsd-proliant/2006-October/000169.html</a> I also found the relevant strings to look for:<br /></p>
<pre>During normal operation of the raid:<br /># camcontrol inquiry da0 -D<br />pass0: &lt;COMPAQ RAID 1 VOLUME OK&gt; Fixed Direct Access SCSI-0 device<br /><br />After removing one of the raid member disks:<br /># camcontrol inquiry da0 -D<br />pass0: &lt;COMPAQ RAID 1 VOLUME inte&gt; Fixed Direct Access SCSI-0 device<br /><br />After re-inserting the raid member disk:<br /># camcontrol inquiry da0 -D<br />pass0: &lt;COMPAQ RAID 1 VOLUME reco&gt; Fixed Direct Access SCSI-0 device<br /><br />And about 45 minutes later:<br /># camcontrol inquiry da0 -D<br />pass0: &lt;COMPAQ RAID 1 VOLUME OK&gt; Fixed Direct Access SCSI-0 device<br /></pre>
<p>You could also use <a id="acu" name="acu">hpacucli, which can be found at </a>http://people.freebsd.org/~jcagle/. I have no experience with it. So if you have, you can send report or scripts to monitor it to me, so I can include it here (the hint to it was send by Jaimie Sirovich.<br /></p>
### 3ware raid: twa/twe
<p>Install and configure <b>sysutils/3dm</b>. This installs a daemon that provides a webinterface and which is also capable to notify you via e-mail if something happens. This is perhaps the easiest way of monitoring raid in FreeBSD. The other possibility to monitor 3ware raids is via <b>tw_cli</b>.</p>
