HP SIM V5.1 User Guide (356920-009, January 2007)

Storage integration using SNMP
Overview
Storage devices can be broken down into real-time access and backup systems. Real-time access systems
can be subdivided into internal disks, redundant disks (RAID), tape libraries, storage area networks (SAN),
and network attached storage (NAS).
Most data centers have combinations of these systems including:
• Small Business Almost entirely internal disk drives
• Medium Business Varying combination of internal disks and RAID systems
• Large Business Varying combination of internal disks, RAID, and some SAN or NAS
• Enterprise Business Mostly large SAN or NAS, and some RAID and internal disks might be present
HP Systems Insight Manager (HP SIM) can retrieve the information for the internal disk drives for systems
being monitored. This does not mean that HP SIM actively manages and configures each of the systems
previously indicated.
HP SIM can:
• Discover and identify storage systems that are directly attached to a server
• Discover and identify storage systems that are on the network, including tape libraries
• Discover and identify HP StorageWorks Command View storage device manager systems
• Receive storage system events and associate them with the system that generated the event (through
Command View) running on a system, or from a tape library management card
• Context launch appropriate management application from the context of the event or the context of the
system running the Command View that generated the event
Storage events
HP SIM enables administrators to monitor inventory and, configure and manage hardware resources and
the system software that affects the systems.
HP SIM provides the administrator with a complete overview of the hardware status. Storage events provide
notification that a problem exists that could affect the availability of storage resources, which can affect
system and application availability. HP SIM receives detailed event messages through WBEM events or
SNMP traps. These events identify the system and the affected disk and provide an error number for looking
up details and a description of the problem. The event details also contain links to the Command View server
that generated the event. HP SIM associates a disk or RAID subsystem with the controller managing these
drives for internal storage.
Storage inventory details
HP SIM inventory retrieves and stores the following information from internal disk drives:
• Disk
Total number of disk slots•
• Number of used slots
• Slot ID
• The type of disk in slot
• Disk manufacturer
• Disk model
• Disk part number
• Disk characteristics
