-===== 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!
-===== PERC 5/i =====

-===== 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
