Description: Monitors Mylex DAC960 SCSI RAID controller status, drives, and array health.

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 MYLEXDAC960SCSIRAIDCONTROLLER-MIB?

MYLEXDAC960SCSIRAIDCONTROLLER-MIB is a vendor-specific MIB from Mylex for its DAC960 family of SCSI RAID controllers, a hardware storage-management technology area. It exposes objects identifying controller manufacturer, product, firmware version, and serial number, along with controller-level and component-indirection tables implying physical/logical drive and array status. Its core purpose is hardware status monitoring for storage subsystems — tracking RAID controller identity/firmware version, controller count, and component verification/health, which is critical for catching a failed/degraded drive or array before data loss occurs. It relies on the SNMPv2 SMI framework (evident from the "v2" object) and is a self-contained enterprise MIB with no dependency on other RAID vendors' MIBs. It's typically deployed on servers fitted with Mylex DAC960 SCSI RAID controllers, where MYLEXDAC960SCSIRAIDCONTROLLER-MIB SNMP monitoring by storage-monitoring tools watches RAID health.

IPNetwork Monitor allows you to monitor SNMP objects defined in MYLEXDAC960SCSIRAIDCONTROLLER-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

Mylex DAC960 SCSI RAID controller
server with Mylex RAID storage

Monitoring Examples

An administrator would poll a1Manufacturer, a1Product, a1Version, and a1SerialNumber (reached via the tComponentid/eComponentid indirection objects) to identify the exact DAC960 controller model and firmware revision installed, and use a2ControllerNumber together with tControllerInformation/eControllerInformation to enumerate each controller in a multi-controller server. The a1Verify object suggests a data-verification/consistency-check status is exposed per component. A storage admin would watch for a1Verify indicating a failed verification pass or an unexpected drop in reported controller count, either pointing to a degraded RAID array or an offline controller.
