SNMP Notification

SNMP notification directs the software to send remote notification of array events to
the administrator’s host by using SNMP traps. An SNMP trap is a user datagram
protocol (UDP, a protocol that converts data messages generated by the system into
data packets) that is sent to a set of hosts that are identified by their IP addresses.
The contents of the trap message include header information that identifies the type
of trap and the data associated with the trap message.

When an event occurs in the array that requires attention, a trap is asynchronously
sent to the administrator’s host to report the event. The host(s) to which the trap is
sent is configured by the user. The host software that receives the trap is an SNMP
management package.

The arrays use the

/etc/syslog.conf

file to trigger the SNMP trap. This file

contains four levels of error warning for the administrator’s attention. Refer to Sun
StorEdge T3 Array Administrator’s Guide for instructions on how to set up SNMP
notification.

An SNMP Management Information Base (MIB, the variables stored by an SNMP
agent) file is provided with the array for use with SNMP-based applications. The
MIB file is located in the following array directory:

/web/snmp/t300.mib

To use this file, copy the MIB file from the array to your SNMP management host
and refer to your specific SNMP management documentation for the correct MIB file
installation procedures.

Syslog Error Reporting

A syslog daemon is a background utility function that is activated to report specified
system conditions. The hardware RAID controller contains a syslog daemon that
reports system messages and provides for remote monitoring. There are four
possible levels of system messages.

■

Error. Indicates a critical system event that requires immediate user attention. An
example would be an over-temperature condition.

■

Warning. Indicates a system event that will eventually require user attention. An
example would be a disabled FRU with a recovery procedure being executed.

■

Notice. Indicates a system event that might be a side effect of other events or
possibly a normal condition. An example would be a power switch in the off
position.

■

Information. Indicates a system event that has no effect on the health of the
system. An example would be the reporting of the healthy state of a FRU.
