Check HP MSA (Modular Smart Array) sensors

Project Notes

This plugin checks all sensors of an HP MSA array.
Currently successfully tested with :

HP MSA2312i
HP MSA2012i
HP MSA2012fc
HP MSA2324i
HP P2000 G3 MSA (iSCSI & FC)

Usage : check_msa_hardware.pl -H [ hostname | IP address ] -C [ SNMP community ]
Don't forget to enable SNMP on the MSA.

This plugin checks HP MSA probes. Thoses probres can be temperature sensors, voltaic sensors, hard disk states (from SMART), power supply states, and many things more.
Each probes send their status which can be "warning" or "critical" according to their severity. Then, the worst state is send back to Nagios.

Example usage:
[root@supervision libexec]# ./check_msa_hardware.pl -C public -H 10.1.1.4
HP StorageWorks MSA2012i: Power Supply 2 Voltage, 12V: 1.75V [power-supply]. Power Supply 2 Voltage, 5V: 0.02V [power-supply]. Overall status value: Failed [enclosure]. CRITICAL

There is a new option --list which list all available probes on your HP MSA:

[root@supervision libexec]# ./check_msa_hardware.pl -H 10.1.1.4 -C public --list -v 2

Nota1: It should now work with SNMP V1 and V2
Nota2: People having Service check did not exit properly error messages may change the nagios command definition by adding the full path to perl executable in front of this plugin:
define command{
command_name check_msa_sensors
command_line /usr/bin/perl $USER1$/check_msa_hardware.pl -H $HOSTADDRESS$ -C $_HOSTSNMPCOMMUNITY$ -v 2
}
This is needed because your nagios may be built with Embeded Perl in it.
