Quantum Scalar i500, Reference Manual

Page: 10 / 156

4 Description
You can, however, configure the framework application to return status information as a string value, which
provides a description of the status. For example, the return value of
Library Main Door might be closed(2) .
To do this, you must compile and integrate the library’s MIBs with your framework application.
SNMPv3
Although the Scalar i500 supports SNMP version 1 and version 2c for MIB information retrieval, we strongly
recommend that you access the library using SNMP version 3 (SNMPv3). SNMPv3 is the most secure of
the three versions, as it supports message digest 5, or MD5, as its authentication protocol.
To access the library for SNMP support, use the following values as needed in the remote management
application:
User name: Admin
Context name: (None. Leave this field blank.)
Authentication protocol: MD5
Privacy protocol: (None. Leave this field blank.)
Password: Your Admin password
For secure access to the library using SNMP, disable SNMPv1 and SNMPv2c access from the remote web
client and the operator panel. For more information, see either the
Scalar i500 User’s Guide or the relevant
Scalar i500 online help topics.
SNMP Traps
Traps enable alerts to be sent automatically to registered hosts when specific events occur. Only one
application per UDP port can listen for traps.
The Scalar i500 only supports SNMP v1 traps as defined by RFC 1157.
To receive traps, you must perform two steps:
1 Configure your framework application to collect traps from the Scalar i500.
2 Using the library’s SNMP Trap Registrations feature, register the host’s IP address, transport protocol,
and UDP port number.
Registration informs the Scalar i500 to send traps to the host.
For additional details about registering a host with the Scalar i500, refer to the Scalar i500 Tape Library
User’s Guide .
SNMP Queries
SNMP queries, or GET queries, can be 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 ID. The instance identifies a specific device from which you can retrieve
status information. For example, to determine if the second partition on a Scalar i500 is online, access the
MIB variable for logical library online status and select the instance for partition 2.
CAUTION
As with any SNMP device, excessive MIB queries can result in performance
degradation for the SNMP daemon, as well as for the network.
