What Is SCC-RAID7-MIB?

SCC-RAID7-MIB is a vendor-specific MIB from SCC, a RAID storage subsystem vendor, for managing RAID7-series storage array controllers. It exposes controller-level status such as firmware/system version, total and available memory, and cache hit percentage, along with block/volume configuration (block size, number of blocks) and per-host-channel configuration and status. Its monitoring value strongly emphasizes hardware and performance status of the storage subsystem: raid7SysVersion reports firmware version, raid7TotalMem/raid7GoodMem/raid7MemAvail reveal controller memory health (a drop in raid7GoodMem could indicate failing memory), and raid7CacheHitPercent is a key performance indicator for cache efficiency, while the channel and block tables let an administrator confirm each host interface channel and logical block configuration are correctly reported. It does not appear to build on a standard storage MIB and instead defines its own SCC-proprietary object tree. It is deployed by storage administrators managing SCC RAID7 disk arrays in server/SAN environments needing block-level storage monitoring, typically starting with an SCC-RAID7-MIB download to compile into their monitoring platform.

IPNetwork Monitor allows you to monitor SNMP objects defined in SCC-RAID7-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.

Monitoring Examples

An administrator would poll raid7CacheHitPercent regularly to track cache efficiency, where a sustained drop could indicate a workload change or a failing cache module, alongside raid7GoodMem and raid7MemAvail to detect controller memory degradation. raid7BlockTable / raid7BlockEntry rows would be checked for raid7BlockSize and raid7NumBlocks to confirm logical volume geometry matches expectations, while raid7ChannelTable / raid7ChannelEntry rows (alongside raid7NumHostChannels) would be polled to verify each host channel is present and reporting correctly.

What Can Be Monitored

system/firmware version
total, good, and available controller memory
cache hit percentage
block size and block count
host channel configuration/count

OIDs

OID symbolic	OID numeric	Type	Access	Description
NTF raid7DriveUp	1.3.6.1.4.1.1386.2.1.0.1			This trap is sent whenever the state for a drive changes to data or parity from any other value. An equivalent poll would be to poll raid7NumberDrives and raid7FailedDrives and then read the raid7DriveTable when one of them changes.
NTF raid7DriveDown	1.3.6.1.4.1.1386.2.1.0.2			This trap is sent whenever the state for a drive changes from data or parity to any other value. An equivalent poll would be to poll raid7NumberDrives and raid7FailedDrives and then read the raid7DriveTable when one of them changes.
NTF raid7EnvironmentFailure	1.3.6.1.4.1.1386.2.1.0.3			This trap is sent when the value of raid7EnvironmentStatus changes to failure.
