Nagios plugin to check current server's RAID status

This plugin checks all RAID volumes (hardware and software) that can be
identified.

This is supposed to be a general plugin to run via NRPE.
It checks for the various RAID systems, and verifies they are working correctly.

Some checks require root permission, that is acomplished using sudo.

Plugin can install neccessary sudo rules (detected for your system), when invoked with -S argument.
You need to be root user and it will add required lines to the sudoers file.

Currently supported:
- Adaptec AAC RAID via aaccli or afacli or arcconf
- AIX software RAID via lsvg
- HP/Compaq Smart Array via cciss_vol_status (hpsa supported too)
- HP Smart Array Controllers and MSA Controllers via hpacucli (see
  hapacucli readme)
- HP Smart Array (MSA1500) via serial line
- Linux 3ware SATA RAID via tw_cli
