Description: LeftHand Networks MIB providing system information and hardware inventory for LeftHand NUS iSCSI storage appliances.
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 LEFTHAND-NETWORKS-NUS-COMMON-INFO-MIB?
LEFTHAND-NETWORKS-NUS-COMMON-INFO-MIB is a vendor-specific SNMP module from LeftHand Networks (later HP StorageWorks) providing general system information and hardware inventory for LeftHand NUS iSCSI storage appliances (NSM storage nodes). It exposes identity data such as serial number, model, software version, and DSP firmware version, alongside environmental and hardware health readings including motherboard and CPU temperature, CPU fan speed, and a power supply status table. This MIB is heavily oriented toward monitoring hardware and software status: it directly reports temperature sensors, fan speed, power supply presence/status, and installed firmware/software version, the classic signals used to detect overheating, a failing fan, or a dead power supply on a storage node. It complements the companion LEFTHAND-NETWORKS-NUS-COMMON-STATUS-MIB, which layers a simplified overall status/message on top of this raw inventory data. It is typically deployed in HP LeftHand/StoreVirtual iSCSI SAN clusters for hardware health and inventory monitoring. Engineers can download the LEFTHAND-NETWORKS-NUS-COMMON-INFO-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in LEFTHAND-NETWORKS-NUS-COMMON-INFO-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
- HP LeftHand Networks NUS/NSM iSCSI storage appliance
- HP StoreVirtual storage node
Monitoring Examples
An administrator polls infoMotherboardTemperature and infoCPUTemperature alongside infoCPUFanSpeed to detect early signs of cooling failure inside the storage node chassis. infoPowerSupplyTable/infoPowerSupplyEntry (indexed by infoPowerSupplyIndex) exposes infoPowerSupplyStatus for each supply in infoPowerSupplyCount, so a status change from normal to failed on one supply triggers an alert on a redundant-PSU node. infoSoftwareVersion and infoDSPFirmwareVersion let the admin audit whether all nodes in a cluster are running consistent firmware. infoSerialNumber and infoModel support asset inventory reporting.
What Can Be Monitored
- motherboard and CPU temperature
- CPU fan speed
- power supply status per unit
- installed software/firmware version
- serial number and model
- power supply count
