Scalar i2000 Basic SNMP Reference Guide 1

About This Guide and Your Product

This reference guide describes the basic usage of the Simple Network Management Protocol (SNMP) to

acquire alert information from the Scalar® i2000 library. Focus is placed on the most critical information

available through Traps and Management Information Base (MIB) queries. For information about the Scalar

i2000 library, itself, refer to the Scalar i2000 User’s Guide. For information on integrating MIBs into a SNMP

management application, contact your software vendor.

The information presented in this document represents the most commonly requested MIB objects and

SNMP Traps needed to monitor the Scalar i2000 from a network management tool. For more information

about the Scalar i2000 MIBs, contact technical support.

This basic SNMP reference is written for library customers, partners, third party management software

developers, and other parties interested in integrating the Scalar i2000 library with commercial management

frameworks.

This document assumes the reader has a working knowledge of SNMP. The reader should be able to

compile a MIB on their specific framework application, perform SNMP GET operations, as well as

understand how to collect Traps and filter them for information.

Explanation of Symbols and Notes

The following symbols appear throughout this document to highlight important information.

Scalar i2000 Basic SNMP Reference Guide 5

Description

SNMP is a light-weight protocol designed for remote management and monitoring of infrastructure devices.

On the Scalar i2000, SNMP support is included for alert monitoring by means of framework applications.

SNMP should be used as an initial check for library events.

In-depth monitoring and alert management are handled using the Library Management Console (LMC). The

LMC provides access to descriptions of subsystem status and to the RAS ticket system, which gives

administrators the ability to diagnose specific subsystem events.

SNMP Functionality Available to External Applications

The Scalar i2000 provides standard SNMP functionality for monitoring library status. This includes GET

queries and unicast Traps (sent only to registered recipients). SET commands are not currently enabled on

the Scalar i2000.

The MIB variables described in this document are the only ones supported by Quantum for external

management of the library. All other variables in the MIB are for internal use only.

Specific Scalar i2000 SNMP characteristics include:

• Support for SNMP v1 and v2c

• Usage of well known ports for GETs (161)

• Default community read/Trap strings: public

• Trap Registration interface in the LMC to configure application IP addresses and user-configurable

UDP port numbers to receive Traps

Accessing SNMP Information

SNMP information is accessed from the Scalar i2000 through Traps and GET queries. Using the information

contained in this guide, an administrator can configure their framework application to receive Scalar i2000

SNMP information and generate alerts.

By default, SNMP information gathered will be an integer value (logical partition names will be string values).

For instance, the return value of Library Main Door might be 2. As outlined in this manual, a return value of

2 would indicate that the library door is closed.

6Description

It is possible to have the framework return a status value and a description of the status. To accomplish this,

the ADIC MIBs must be compiled and integrated with the framework application. In this case, the return

value of Library Main Door might be closed(2). The required MIBs are discussed in MIBs Implemented on

page 17 and are available from your Quantum representative.

SNMP Traps

Traps are automatically sent to registered hosts when specific events occur. You can only have one

application per port listening for traps, so if you have more than one application, make sure that you specify

a UDP port on which to send traps.

To receive Traps, you must perform two steps:

1Configure the framework application to collect Traps from the Scalar i2000.

2Using the LMC Trap Registration feature, register the host’s IP address and UPD port number on the

Scalar i2000.

Registration informs the Scalar i2000 that Traps should be sent to the host. For details on registering a host

with the Scalar i2000, see the Scalar i2000 User’s Guide or the LMC online help.

SNMP Queries

GET queries are initiated on a periodic basis by the framework application. By querying the MIB, hosts can

gather status information about specific components of the library. Frequent MIB queries are not required,

however, since the SNMP agent is event-driven.

GETs must also include an instance number. This instance ID tells the Scalar i2000 what specific device to

provide status information on. For example, to see if the 2nd logical library on a Scalar i2000 was online,

you would access the MIB variable for logical library online status and select the instance for logical library 2.

The format of each instance may vary depending on the subsystem component. This document provides a

listing of the instance format for each MIB variable you may need to query. You will notice that almost every

instance contains 8.0.0.0.0.0.1.0.59. This is the identifier for the Management Control Blade (MCB), the

device that manages the Scalar i2000.

Therefore, if you were querying logical library status, you might see the following two instances returned.

Selecting instance 8.0.0.0.0.0.1.0.59.2 would indicate if the second logical library was online or offline.

CAUTION

As with any SNMP device, excessive MIB queries can result in

performance degradation for the SNMP daemon, as well as for the

network.

Instance Number Description

1 8.0.0.0.0.0.1.0.59.1 the first logical library

2 8.0.0.0.0.0.1.0.59.2 the second logical library

Note

All Scalar i2000 MCB’s will have the same identifier: 8.0.0.0.0.0.1.0.59
