MegaRAID:
=====================================



/etc/smartd.conf

/dev/sda -d megaraid,0 -a -s S/../.././01
/dev/sda -d megaraid,1 -a -s S/../.././02
/dev/sda -d megaraid,2 -a -s S/../.././03
/dev/sda -d megaraid,4 -a -s S/../.././04

sudo service smartmontools restart

========================================

/etc/munin/plugin-conf.d/smart_

[smart_*]
user root
group disk


[smart_sda-0]
env.smartargs -d megaraid,0 -a

[smart_sda-1]
env.smartargs -d megaraid,1 -a

[smart_sda-2]
env.smartargs -d megaraid,2 -a

[smart_sda-3]
env.smartargs -d megaraid,3 -a

========================================


Create symlinks in /etc/munin/plugins

smart_sda-0 -> /usr/share/munin/plugins/smart_
smart_sda-1 -> /usr/share/munin/plugins/smart_
smart_sda-2 -> /usr/share/munin/plugins/smart_
smart_sda-3 -> /usr/share/munin/plugins/smart_

ln -s /usr/share/munin/plugins/smart_ smart_sda-0
ln -s /usr/share/munin/plugins/smart_ smart_sda-1
ln -s /usr/share/munin/plugins/smart_ smart_sda-2
ln -s /usr/share/munin/plugins/smart_ smart_sda-3


========================================

Validate on host itself

raw disk check

smartctl -d megaraid,0 -a /dev/sda  (1,2,3)

munin-run smart_sda-0 (1,2,3)
