===== 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]]
07:08.0 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
