Hitachi HNAS: Status of System Drives
This check monitors the status of system drives of Hitachi NAS-Devices.
It was tested against Hitachi HNAS Modell 3090 but probably will work
for other HNAS devices using the BlueArc MIB.
The check works by scanning the SNMP status information of all system drives
as given by the device. It displays the number of drives found in each of the
known states - if it is non-zero. Known states are: "Online", "MBR corrupt",
"Failed and unaccessible", "Not present", "Not accessible by controller",
"Offline", "Initializing", "Formatting", "Unknown",
All stati except "Online" and "Unknown" trigger a CRIT state of
the service. "Online" triggers OK and "Unknown" triggers UNKNOWN
One check for each device is created.
