What Is RAID-Adapter-MIB?

RAID-Adapter-MIB is a vendor MIB (under the LSI/MegaRAID enterprise branch) for monitoring hardware RAID controller adapters used in servers to manage arrays of physical disks. It exposes an adapter table with firmware and BIOS version, DRAM cache size, rebuild rate, and flush interval, alongside per-adapter operational values such as I/O reads per second and configured limits like maximum concurrent commands and drive spin-up delay/count. This is squarely a hardware-health and storage-status monitoring MIB: it tracks logical drive counts and health, RAID rebuild progress after a disk failure, controller firmware/BIOS version for patch compliance, and I/O throughput, all critical indicators of impending or ongoing storage hardware problems. It is a self-contained vendor (LSI/MegaRAID) MIB with no apparent dependency on IETF standard storage MIBs. It is typically deployed on servers equipped with LSI MegaRAID (or OEM-rebranded, e.g., Dell PERC, IBM ServeRAID) hardware RAID controllers in data centers. Engineers can download the RAID-Adapter-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RAID-Adapter-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

  • server hardware RAID controller (LSI/MegaRAID and OEM-rebranded equivalents such as Dell PERC or IBM ServeRAID)

Monitoring Examples

An administrator monitoring array health after a disk replacement would poll numLogicalDrives via adapterTable (keyed by adpAdapterNumber) to confirm the expected number of logical drives are present, and watch rebuildRateInPercent to track how quickly a degraded array is rebuilding onto a replacement disk. firmwareVersion and biosVersion are checked to confirm the controller runs a supported release before a maintenance window, while adpIOReadsPerSec gives a real-time view of storage load that can reveal a bottleneck. A dropping numLogicalDrives count or a stalled rebuildRateInPercent indicates a failing rebuild or an additional disk failure.

What Can Be Monitored

  • number of logical drives
  • RAID rebuild rate/progress
  • controller firmware version
  • controller BIOS version
  • DRAM cache size
  • I/O reads per second
  • maximum concurrent commands / spin-up settings
