LSI Hardware RAID - S.M.A.R.T Monitoring

Check will detect number of drives attached to controller and query them all for overall smart health based off of smartctl's analysis of pre-fail attributes etc.

>> Returns OK if all attached drives return healthy.

>> Returns Warning if storcli could not be found.

>> Returns Critical if one or more drives report unhealthy. And proceeds to pull the device ID# (slot#), drive device name and serial number and prints this info witht he Critical messsage in Nagios Core.

Relies on smartctl (From SmartMonTools) and StorCli (MegaRAID CLI, successor to megacli)

Run check under sudo in command definition, ensure Nagios can run both storcli and smartctl under sudo by editing visudo with the following lines:

Change:
Defaults requiretty

To:
Defaults requiretty
Defaults:nagios !requiretty

Change:
## Allow root to run any commands anywhere
root ALL=(ALL) ALL

To:
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
nagios ALL=(ALL) NOPASSWD:/usr/sbin/smartctl
nagios ALL=(ALL) NOPASSWD:/opt/MegaRAID/storcli/storcli64

Edit the check file and set the storcli location to wherever your storcli binary is. Same with the visudo additions.
