description:
 This check monitors the state of logical disks (RAID arrays) of an LSI
 MegaRAID Controller. The Linux agent sends the necessary data,
 if the command line utility {MegaCli} is found in the shells
 search path. The usual way is to install it into {/usr/local/bin}.

 The utility {MegaCli} can be downloaded from
 {http://www.lsi.com/downloads/Public/MegaRAID%20Common%20Files/8.02.16_MegaCLI.zip}.
 This is an alternative to the utility {cfggen}. {cfggen} only works
 with the driver {mptsas}, whereas {MegaCli} uses a device created
 by the driver {megaraid_sas}.

 All states other than {Optimal} are considere critical.

item:
 The number of the adapter and the logical disk, separated by a slash, e.g. {"0/0"}.

discovery:
 One service is created for each logical disk.
