Hardware Controller Silence Alarm
From OSNEXUS Online Documentation Site
Turns off the hardware alarm that is built into many hardware RAID controllers. Alarms can happen when equipment gets to hot or in cases where a RAID unit is degraded.
It is also possible to permanently disable alarm which is often recommended for datacenter and co-lo placement but for that you'll need to use the console to use the vendor's CLI tool to disable the setting on the controller.
Note: LSI based controllers, the command is: sudo MegaCli -AdpSetProp AlarmDsbl -aALL
