Description: HP StorageWorks LeftHand Networks MIB defining SNMP notifications and traps for HP P4000 SAN storage system events.

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-NOTIFICATION-MIB?

LEFTHAND-NETWORKS-NSM-NOTIFICATION-MIB is HP StorageWorks's proprietary MIB (originally from LeftHand Networks, acquired by HP) defining SNMP notifications for the Network Storage Module (NSM) storage nodes used in the HP P4000 SAN storage system, delivered as both SNMPv1 traps and SNMPv2c informs. It exposes counters and tables tracking current and historical notification messages generated by the storage system. Its status-monitoring role is centered on fault/event tracking for storage hardware: rather than exposing continuous sensor readings, it tracks how many notification events (such as disk, node, or cluster-related faults) have occurred and archives older ones for audit. It relies on the standard SNMPv1 Trap-PDU and SNMPv2c Inform-PDU delivery mechanisms as its transport and is one of a family of related LeftHand/NSM MIBs. It is deployed on HP P4000/LeftHand SAN storage clusters in enterprise data centers using SAN/iQ clustered storage. Engineers can download the LEFTHAND-NETWORKS-NSM-NOTIFICATION-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in LEFTHAND-NETWORKS-NSM-NOTIFICATION-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 / LeftHand Networks SAN storage node

Monitoring Examples

An administrator polls notificationMessageCount and watches it against notificationOldMessageCount to see whether unacknowledged storage events are accumulating in notificationMessageTable. Entries that age into notificationOldMessageTable represent historical notifications an admin can review after an incident, such as a disk failure or node going offline, to reconstruct the fault timeline for the storage cluster.

What Can Be Monitored

  • current notification message count
  • historical/old notification message count
  • notification message table contents
  • storage fault/event history

How to Use in IPNetwork Monitor

Example using fanSpeed OID:

Select an HP StorageWorks P4000 / LeftHand Networks SAN storage node (traps/informs) 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 fanSpeed 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 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.
