SNMP Messaging

Occasionally, the library may encounter a situation that you want to know about,

such as an open magazine or a fault that causes the library to stop. The library

provides a standard TCP/IP protocol called Simple Network Management Protocol

(SNMP) to send alerts about conditions (such as need for operator intervention)

over a TCP/IP LAN network to an SNMP monitoring station. These alerts are

called SNMP traps. Using the information supplied in each SNMP trap, the

monitoring station (together with customer-supplied software) can alert operations

personnel of possible problems or operator interventions that occur.

SNMP Traps

SNMP traps are alerts or status messages that can be collected, monitored and

used to proactively manage attached libraries using SNMP protocol with the host

server(s). In summary, each trap provides the following information:

v Product Identification such as product name, description, manufacturer, model

number, firmware level, and the URL that the trap is designated for.

v Product Status such as the severity of the trap, status (current and previous) and

the time the trap occurred.

v Library State (physical device status) such as identification and status of devices

that are monitored. In the case of the library, it would include enclosure, power

supply, controller, magazine status, drive count, cartridge slot count, and I/O

station count. Also included would be certain library statistics, and where

appropriate, the fault FSC (fault symptom code) including the severity and

description of that fault.

v Drive Status such as the identification of each drive in the library, firmware

level, serial number and other address and status information.

v Trap Definitions such as library status change, open magazine, I/O accessed,

hard fault information, drive cleaning requests, excessive retries and library

returning to normal operations. For additional information, refer to Appendix G.

"SNMP Status MIB Variables and Traps" on page G-1.

v SNMP MIBs: The library's Management Information Base (MIB) contains units

of information that specifically describe an aspect of the system, such as the

system name, hardware number or communications configuration. Status and

error data is also gathered by MIBs and sent to one or more IP addresses

defined during the SNMP configuration operation. Download the SNMP MIB

file for this library from http://www.support.dell.com.
