PACKETLOGIC-RAID-MIB

Description: Monitors RAID array status, disk health, and rebuild progress on Procera Networks PacketLogic appliances.

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.

This is a Procera Networks vendor MIB for the PacketLogic2 platform, specifically targeting the RAID storage subsystem used by these deep packet inspection appliances. It exposes data on logical drives (ld) and physical disks (disk), including their identifiers, states, and RAID configuration parameters. It is squarely focused on monitoring hardware status, specifically disk and RAID array health, letting an operator see whether a logical drive or individual disk is degraded, failed, or rebuilding, which is critical since PacketLogic appliances rely on local storage for logging and reporting data. As a storage-focused vendor MIB it likely complements broader PacketLogic system MIBs covering CPU, memory, and general appliance health, though no explicit dependency is stated. It is typically deployed by network operators and ISPs running Procera PacketLogic DPI/traffic-management appliances where local disk reliability directly affects subscriber traffic reporting. Network engineers evaluating or troubleshooting this functionality can download the PACKETLOGIC-RAID-MIB file directly to load it into their MIB browser.

An administrator would poll the ldEntry table (indexed by ldEntryIndex) to check ldState for each logical drive and the diskEntry table (indexed by diskEntryIndex) to check diskId and disk health for each physical disk in the array, referencing adpNumber for the RAID adapter, ldNumber for the logical drive, and diskNumber for the physical disk position. An ldState showing degraded or rebuilding combined with a specific diskId reporting a fault would reveal a failed disk that needs replacement before a second failure causes data loss. The raidCfg object would confirm the overall RAID configuration in use, giving storage-level fault visibility that general appliance health checks might miss.
