Description: H3C MIB for flash storage management on network devices including file operations and storage capacity.

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-FLASH-MAN-MIB?

H3C-FLASH-MAN-MIB is a vendor MIB from H3C (Hewlett-Packard/3Com's China-based networking arm) for managing flash storage cards and their operations on H3C network devices such as routers and switches. It exposes hardware inventory and status data about installed flash storage modules, including their size, position, chip count, description, initialization time, and whether they are removable or partitioned. This is directly a hardware-status monitoring MIB: it lets an administrator confirm that a flash storage card is present, correctly sized, and initialized, which is important for tracking storage health used for firmware images, configuration backups, and boot files on the device. It depends on general SNMPv2 SMI conventions and complements chassis/entity-level hardware MIBs (such as ENTITY-MIB) that H3C devices also typically support. It is typically deployed on H3C routers and switches that support removable or onboard flash storage cards for firmware and configuration storage. Engineers can download the H3C-FLASH-MAN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-FLASH-MAN-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 router
  • H3C Ethernet switch

Monitoring Examples

An administrator would poll the h3cFlashTable, indexed by h3cFlhIndex, to read h3cFlhSize, h3cFlhPos, h3cFlhName, and h3cFlhInitTime for each installed flash card, along with h3cFlhRemovable and h3cFlhPartitionBool to understand its physical characteristics. Comparing h3cFlhSize against expected capacity, or noticing a flash card missing from the table (compared to h3cFlhSupportNum, the expected count of flash slots), would reveal a failed or removed storage module. This is useful for catching storage hardware problems before a firmware upgrade or configuration save fails.

What Can Be Monitored

  • installed flash card count
  • flash card size/capacity
  • flash card position and chip count
  • flash card removable/partition status
  • flash card initialization time

How to Use in IPNetwork Monitor

Example using h3cFlhChipWriteTimes OID:

Select an H3C router/switch (flash storage card management) 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 h3cFlhChipWriteTimes 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. It reports a count of write times (retries) for the flash chip since initialization. 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 Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
