Description: HP StorageWorks LeftHand Networks MIB for managing network interface configuration 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-NETWORK-MIB?

LEFTHAND-NETWORKS-NSM-NETWORK-MIB is an HP StorageWorks/LeftHand Networks SNMP module covering network interface configuration on P4000 series SAN storage nodes running the SAN/iQ software. It's a narrowly-scoped module whose primary content is a network device count and a network device table enumerating each node's network interfaces. Its practical use for status monitoring is verifying how many network interfaces a storage node has configured and detecting changes in that interface inventory, which can signal a NIC failure, an added bonding/teaming interface, or a misconfiguration. As with its sibling LeftHand modules it defines its own AGENT-CAPABILITIES/conformance groups and depends mainly on standard SNMPv2 conventions rather than other IETF MIBs, though it complements the standard IF-MIB for full interface statistics. It's deployed in HP P4000/LeftHand SAN clusters alongside the clustering and storage MIBs, giving admins network-path visibility for the storage nodes, an area where LEFTHAND-NETWORKS-NSM-NETWORK-MIB SNMP monitoring complements cluster health checks.

IPNetwork Monitor allows you to monitor SNMP objects defined in LEFTHAND-NETWORKS-NSM-NETWORK-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 node (LeftHand Networks SAN/iQ)

Monitoring Examples

An admin would poll networkDeviceCount and walk networkDeviceTable/networkDeviceEntry to enumerate each network interface configured on a P4000 storage node and confirm the expected count of NICs/bonded interfaces is present. A sudden drop in networkDeviceCount compared to the node's known hardware configuration would indicate a failed or disconnected network adapter. This module is typically polled alongside LEFTHAND-NETWORKS-NSM-CLUSTERING-MIB to correlate network health with cluster quorum status.

How to Use in IPNetwork Monitor

Example using networkDeviceCount OID:

Select an HP StorageWorks P4000 SAN storage node (LeftHand SAN/iQ network interfaces) 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 networkDeviceCount into the Find box to locate it in the OID tree, then select it and click OK. The number of network devices. 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 an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the count changes from its expected baseline, since that would indicate the underlying set of items changed unexpectedly. Click Finish to create the monitor; you can adjust any parameter later.
