Category: Legacy and Historical, Storage

Description: Defines Symbios DMI 2.0 component ID 2.0 instrumentation objects for legacy storage controller management.

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 SYMBIOSDMI20MIFDEFINITIONID20-MIB?

This is a legacy MIB translating DMI (Desktop Management Interface) 2.0 MIF component definitions from Symbios Logic, a SCSI/storage controller vendor later folded into LSI/Adaptec, into SNMP objects for storage controller management. It exposes hardware/software inventory data for a component abstraction, manufacturer, product name, version, serial number, installation, and verification status, plus a subcomponent-software table tracking installed software/firmware modules by index. This lets administrators monitor both hardware identity (serial number, product/version) and software status (installed firmware/driver version per subcomponent) of legacy SCSI storage controllers, important for confirming firmware compatibility and asset tracking. Being a DMI-to-SNMP translation, it is explicitly dependent on the DMI 2.0/MIF standard and the SCSI component model it mirrors. It was typically deployed on legacy servers using Symbios/LSI SCSI RAID or host bus adapter controllers managed through DMI-aware system management software. Network engineers evaluating or troubleshooting this functionality can download the SYMBIOSDMI20MIFDEFINITIONID20-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SYMBIOSDMI20MIFDEFINITIONID20-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

  • Symbios/LSI SCSI storage controller
  • legacy server with DMI-managed host bus adapter

Monitoring Examples

An administrator reads a1Manufacturer, a1Product, a1Version, and a1SerialNumber to confirm the exact SCSI controller model and firmware/hardware revision installed in a server, and checks a1Verify/a1Installation status to confirm the component passed self-verification after installation. The a2SoftwareIndex under tSubcomponentSoftware/eSubcomponentSoftware would be polled to confirm which firmware/driver version is active on a given subcomponent, with a mismatch indicating an outdated or failed firmware update.

What Can Be Monitored

  • controller manufacturer/product/version identity
  • serial number
  • installation/verification status
  • subcomponent software/firmware index
