Description: AMI MegaRAID RAID controller management including logical/physical disk status and battery backup.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is AMIMEGARAIDMIF-MIB?

AMIMEGARAIDMIF-MIB is a MIB (apparently converted from a DMTF MIF/DMI component definition, given field names like tComponentid and a1-prefixed attributes) from American Megatrends for managing its widely-OEM'd MegaRAID RAID controllers, covering controller identification along with logical/physical disk and battery-backup status per its short description. It exposes hardware inventory-style data - manufacturer, product name, firmware version, and serial number - for the RAID controller component, grouped under a controller-information object with an adapter-number index. Its monitoring value centers on hardware status: identifying exactly which controller model and firmware revision is installed, and (per the module's broader scope) the health of logical/physical drives and the battery backup unit that protects the controller's write cache - critical for catching a failing disk or battery before data is at risk. It follows the DMTF MIF component/group conventions ported into SNMP form rather than a native SNMP MIB design. It is deployed on servers equipped with AMI MegaRAID controllers in enterprise and data-center environments. Engineers can download the AMIMEGARAIDMIF-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in AMIMEGARAIDMIF-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Servers equipped with AMI MegaRAID RAID storage controllers

Monitoring Examples

Under tControllerInformation/eControllerInformation, indexed by a2Adpadapternumber, the attributes a1Manufacturer, a1Product, a1Version, and a1SerialNumber let an admin inventory exactly which MegaRAID controller and firmware revision is installed in a given server, while a1Installation and a1Verify indicate the component's installation/verification state. The excerpt available here does not include the specific logical-drive or battery-backup status objects referenced in the module's short description, so those details cannot be confirmed beyond the controller-identification fields shown.

What Can Be Monitored

RAID controller manufacturer/product/version
controller serial number
controller installation/verification status
adapter number identification
