Description: HP StorageWorks LeftHand Networks MIB for monitoring system information and inventory on HP P4000 SAN storage nodes.

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-NSM-INFO-MIB?

LEFTHAND-NETWORKS-NSM-INFO-MIB is a MIB originally from LeftHand Networks and carried forward by HP StorageWorks for its P4000 SAN storage nodes, providing general system information and hardware inventory for these storage appliances. It exposes identification data (serial number, model, software and enclosure firmware versions) alongside hardware health telemetry such as motherboard temperature, CPU count and per-CPU details, and power supply and fan inventories. This makes it directly useful for monitoring the physical hardware health of a SAN storage node: temperature readings flag overheating risk, CPU count/table entries confirm processor health, and power supply/fan tables reveal a failed or missing redundant component, all of which are critical for storage array uptime. Several objects are explicitly marked "Old"/"Obsolete," indicating this MIB has evolved over time and is superseded in places by newer HP LeftHand MIBs, so it should be read alongside its current-generation counterparts. It is deployed on HP StorageWorks P4000 (formerly LeftHand Networks NSM) SAN storage nodes in clustered storage environments, where LEFTHAND-NETWORKS-NSM-INFO-MIB SNMP monitoring tracks hardware health across the cluster.

IPNetwork Monitor allows you to monitor SNMP objects defined in LEFTHAND-NETWORKS-NSM-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 StorageWorks P4000 SAN storage nodes (LeftHand Networks NSM)

Monitoring Examples

An administrator would poll infoMotherboardTemperature to catch a storage node overheating before it triggers a thermal shutdown, and check infoCPUTable/infoCPUEntry against infoCPUCount to confirm all expected processors are present and healthy. infoObsoletePowerSupplyTable and infoObsoleteFanTable (despite the "Obsolete" naming, still often populated) would be checked against their respective count objects to detect a failed power supply or fan needing replacement. infoSerialNumberOld and infoSoftwareVersionOld help confirm which firmware/software revision a given node is running during a fleet audit.

What Can Be Monitored

  • motherboard temperature
  • CPU count and per-CPU status
  • power supply presence/status
  • fan presence/status
  • serial number/model/firmware version

How to Use in IPNetwork Monitor

Example using infoFanSpeed OID:

Select an HP StorageWorks P4000 SAN storage node (LeftHand NSM hardware inventory) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type infoFanSpeed into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The current fan speed. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Gauge32-type OID, Value bounds is the most useful condition here — trigger an alert if the speed drops below the level expected for a healthy, spinning fan, since a stalled or slowing fan often precedes overheating. Click Finish to create the monitor; you can adjust any parameter later.
