Description: H3C MIB for monitoring physical disk drive status, capacity, and health in H3C storage and server equipment.

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-DISK-MIB?

H3C-DISK-MIB is an H3C proprietary MIB for monitoring physical disk drives installed in H3C storage arrays, servers, or other devices with local disk storage. It exposes per-disk hardware attributes including port type and speed, total and free capacity, and physical indicator states such as location, run, and fault LEDs. This is explicitly a hardware-health MIB: h3cDiskRunLedState and h3cDiskFaultLedState directly report drive operational and fault status, h3cDiskFreeSpace tracks capacity exhaustion, and h3cDiskGlobalSpare identifies hot-spare disks available for automatic rebuild. It is an H3C-proprietary module with no stated dependency on IETF standards, though it is typically deployed alongside H3C's entity and environmental MIBs for full chassis health monitoring. It is deployed on H3C storage systems and servers equipped with hot-swappable physical disk drives, usually after an H3C-DISK-MIB download is loaded into the monitoring system's MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in H3C-DISK-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 storage array
H3C server with local disk storage

Monitoring Examples

Polling h3cDiskTable/h3cDiskEntry (indexed by h3cDiskIndex) lets an administrator watch h3cDiskFaultLedState transition to a fault condition and h3cDiskRunLedState go dark, signaling a failed drive that needs replacement. Tracking h3cDiskFreeSpace against h3cDiskSize across all disks flags an array approaching full capacity, while h3cDiskGlobalSpare confirms a spare is available to absorb a rebuild.

What Can Be Monitored

disk capacity and free space
disk fault LED state
disk run LED state
disk location/presence state
disk port type and speed
hot-spare disk availability

OIDs

OID symbolic	OID numeric	Type	Access	Description
h3cDisk	1.3.6.1.4.1.2011.10.10.3			This MIB describes the general information of disk device, include the running status, disk interface, and chche management.
h3cDiskMibObjects	1.3.6.1.4.1.2011.10.10.3.1
h3cDiskTable	1.3.6.1.4.1.2011.10.10.3.1.1		not-accessible	This table contains some entity extend information of the disk.
h3cDiskEntry	1.3.6.1.4.1.2011.10.10.3.1.1.1		not-accessible	An entry containing management information applicable to the disk.
I32 h3cDiskIndex	1.3.6.1.4.1.2011.10.10.3.1.1.1.1	Integer32	not-accessible	This object identifies the entity index of disk. The object identified by this index is the same object as identified by the same value of entPhysicalIndex.
INT h3cDiskPortType	1.3.6.1.4.1.2011.10.10.3.1.1.1.2	INTEGER	read-only	This object describes the interface type of disk. The value 'sata' means serial advanced technology attachment. The value 'pata' means parallel advanced technology attachment. The value 'sas' means serial attached SCSI. The value 'scsi' means small computer system interface. The value 'ieee1394' means a type of bus standard. The value 'fcal' means fiber channel arbitrated loop.
I32 h3cDiskPortSpeed	1.3.6.1.4.1.2011.10.10.3.1.1.1.3	Integer32	read-only	This object identifies the speed of disk interface. The units is million bytes per second.
I32 h3cDiskSize	1.3.6.1.4.1.2011.10.10.3.1.1.1.4	Integer32	read-only	This object describes the size of disk's total space. The units is million bytes.
I32 h3cDiskFreeSpace	1.3.6.1.4.1.2011.10.10.3.1.1.1.5	Integer32	read-only	This object describes the size of spare space of the disk. The units is million bytes.
H3C h3cDiskLocationState	1.3.6.1.4.1.2011.10.10.3.1.1.1.6	H3cStorageEnableState	read-write	This object identifies if the led used to confirm the position of disk is enable.
INT h3cDiskRunLedState	1.3.6.1.4.1.2011.10.10.3.1.1.1.7	INTEGER	read-only	This object identifies the runing state of the disk. The value of 'on' means the blue led is on, and the disk works well. The value of 'blink' means the blue led is blinking, and the disk is being readed or writed. The value of 'fastblink' means the blue led is blinking very fast, and the disk is being located. This object can not be 'fastblink' when the value of associated h3cDiskLocationState object is equal to 'disable'.
INT h3cDiskFaultLedState	1.3.6.1.4.1.2011.10.10.3.1.1.1.8	INTEGER	read-only	This object identifies the fault state of the disk. The value of 'off' means the yellow led is go out, and the disk works well. The value of 'on' means the yellow led is on, and the disk break down. The value of 'blink' means the yellow led is blinking, and a group of raid disk is being synchronized.
H3C h3cDiskInitialize	1.3.6.1.4.1.2011.10.10.3.1.1.1.9	H3cStorageActionType	read-write	The operation of initialize the disk. When the value of this object is set to 'action', the operation of disk initialize are touched off.
