Nagios monitors HDD raid

Background: Due to online server hard disk failure, resulting in service, data failure;

Objective: To ensure the first time to find out whether the hard disk information is normal;

Scenario: Use Nagios custom scripts to monitor the drive status;

Note: The following script only provides for the use of HPACUCLI MEGACLI software that has been installed;
