Description: H3C MIB for storage snapshot management including snapshot creation, scheduling, and status on H3C storage systems.

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 H3C-STORAGE-SNAP-MIB?

H3C-STORAGE-SNAP-MIB is a vendor-specific MIB from H3C covering snapshot management on H3C storage arrays and storage-virtualization devices. It exposes configuration objects for snapshot-capable logical volumes, including snapshot area sizing, auto-expansion thresholds and increments (h3cSnapAreaAutoExpand, h3cSnapAreaThreshold, h3cSnapAreaIncSize, h3cSnapAreaMaxSize), plus status and notification objects (h3cSnapAreaStatus, h3cSnapAreaNotify). Its monitoring focus is squarely on storage software/configuration status rather than physical hardware sensors: administrators use it to track whether snapshot reserve space is filling up, whether auto-expand has fired, and the overall status of each snapshot area, catching capacity exhaustion before it causes snapshot failure or data-protection gaps. It is a standalone H3C private-enterprise MIB with no apparent dependency on external storage standards, though it typically coexists with other H3C storage MIBs for volumes and RAID. It is deployed on H3C SAN/NAS storage systems in data centers that rely on scheduled snapshots for backup and recovery. Network engineers evaluating or troubleshooting this functionality can download the H3C-STORAGE-SNAP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-STORAGE-SNAP-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

  • H3C SAN/NAS storage systems
  • H3C storage virtualization devices

Monitoring Examples

An operator would poll h3cSnapConfigTable (indexed by h3cSnapLvIndex/h3cSnapAreaId) and check h3cSnapAreaThreshold against actual usage to catch a snapshot reserve area approaching h3cSnapAreaMaxSize. A rising trend combined with h3cSnapAreaAutoExpand disabled and no headroom under h3cSnapAreaIncSize predicts an imminent h3cSnapAreaFullDeleteTM event where the oldest snapshots get purged. h3cSnapAreaStatus and h3cSnapAreaNotify let the NMS alert before snapshots start failing due to space exhaustion.

What Can Be Monitored

  • snapshot area usage vs threshold
  • snapshot area auto-expand status
  • snapshot area maximum size
  • reserve/additional space sizing
  • snapshot full-delete timestamp
  • snapshot area status/notifications
