+===== Dell PERC 6/i and RAID monitoring =====
+A few pointers for people trying to get Dell's PERC 6/i RAID monitoring working under Ubuntu, and any other linux for that matter. It also applies to PERC 5/i too, and... other stuff :-)
+First, visit [[http://linux.dell.com/|Dells Linux]] site. Have a poke about, see what's there.
+Next, we need to download a tool to get information from your array. Download LSI's MegaRAID CLI tool for linux. It comes as a .RPM, so if you're an ubuntu user, you can convert it to a .deb using alien, or convert it to a .tar.gz.
+   # alien --to-tgz MegaCli-1.01.39-0.i386.rpm
+You then have a CLI tool you can use to get all your data now! For example:
+   # ./opt/MegaRAID/MegaCli/MegaCli64 -LDInfo -Lall -aALL | grep State State: Optimal
+One thing I spent a while figuring out was how to get the rebuild progress, so here's how:
+   # ./opt/MegaRAID/MegaCli/MegaCli64 -PDRbld -ShowProg -PhysDrv \[32:1\] -aALL
+There's also a really useful [[http://tools.rapidsoft.de/perc/perc-cheat-sheet.pdf|cheat sheet]] for common tasks
+Don't forget to actually monitor this output with nagios, or your favorite monitoring tool!

+===== Monitoring Dell SAS 5/iR RAID with nagios =====
+see: [[http://www.drugphish.ch/~ratz/mpt-status/readme.txt]]
+:08.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068 PCI-X Fusion-MPT SAS (rev 01)
+           Subsystem: Dell SAS 5/iR Adapter RAID Controller
+The status of this RAID card can be read using mpt-status, in Gentoo this package is available as sys-block/mpt-status.  Here's an example of the output:
+   # mpt-status
+   ioc0 vol_id 0 type IM, 2 phy, 148 GB, state OPTIMAL, flags ENABLED
+   ioc0 phy 1 scsi_id 32 ATA      WDC WD1600JS-75N 2E04, 149 GB, state ONLINE, flags NONE
+   ioc0 phy 0 scsi_id 1 ATA      WDC WD1600JS-75N 2E04, 149 GB, state ONLINE, flags NONE
+The latest 'check_mpt' script can be found on Nagios Exchange.  Download it and put it in your libexec folder, for me on gentoo its '/usr/nagios/libexec/'.  Open the file, and make sure the 'use lib' line points to the correct place.
+The script uses sudo to run mpt-status, so you'll need to modify your /etc/sudoers - adding a line like this:
+   %nagios ALL=(ALL) NOPASSWD:/usr/sbin/mpt-status
+Next, you need to configure nagios, your filenames might be different from the names I use below.
+/etc/nagios/commands.cfg : Note, the -c param refers to the number of disks you expect to be active.
+   define command{
+     command_name  check_mpt
+     command_line  $USER1$/check_mpt -c 2
+  }
+/etc/nagios/localhost.cfg
+   define service{
+     use                  local-service
+     host_name            localhost
+     service_description  mpt - Dell Raid
+    check_command        check_mpt
+  }
+Reload nagios, on gentoo, it's /etc/init.d/nagios reload
