SNMP Operation & Installation
D-1 Overview
The McRAID storage manager includes a firmware-embedded Simple Network Management Protocol (SNMP) agent
and SNMP Extension Agent for the RAID controller. An SNMP-based management application (also known as an
SNMP manager) can monitor the disk array. An example of a SNMP management application is Hewlett-Packard's
Open View, Net-SNMP or SNMPc. The SNMP extension agent can be used to augment the RAID controller if you are
already running an SNMP management application at your site.
D-2 SNMP Definition
SNMP, an IP-based protocol, has a set of commands for getting the status of target devices. The SNMP management
platform is called the SNMP manager, and the managed devices have the SNMP agent loaded. Management data is
organized in a hierarchical data structure called the Management Information Base (MIB). These MIBs are defined
and sanctioned by various industry associations. Each type of device on your network has its own specific MIB file.
The MIB file defines the device as a set of managed objects — values that can be read or changed by the SNMP
manager. The MIB file enables the SNMP manager to interpret trap messages from devices. To make sense out of a
trap that's sent by a device, the SNMP manager needs to have access to the MIB that describes the format and
content of the possible traps that the device can send. The objective is for all vendors to create products in compli-
ance with these MIBs so that inter-vendor interoperability can be achieved. To be available for the SNMP manager,
a command adds the MIB file for each of devices to the MIB database. This enables the devices to be managed via
the SNMP manager.
The following figure illustrates the various components of an SNMP-based management architecture.
