3.3 Monitoring the Disk Tray
You can monitor the Sun StorEdge T3 disk tray remotely by using any of the
following tools:
■
Sun StorEdge Component Manager software
■
Simple Network Management Protocol (SNMP) notification
■
syslog
error reports
3.3.1 Sun StorEdge Component Manager
The Sun StorEdge Component Manager software provides a graphical user interface
(GUI) to monitor and manage one or more Sun StorEdge T3 disk trays that are
connected to a host. The software enables you to administer some of the components
of the disk tray and also constantly monitors system health. Alarm notification and
remote reporting alert the administrator to abnormal activities or conditions that
require attention. Component Manager can run on any host connected to the same
network as the disk tray.
For more specific information regarding Component Manager and its functions, refer
to the Sun StorEdge Component Manager User’s Guide. For information on installing
the software, refer to the Sun StorEdge Component Manager Installation Guide.
3.3.2 SNMP Notification
SNMP notification directs the software to send remote notification of disk tray
events to the administrator’s host by using SNMP traps. An SNMP trap is a UDP
datagram 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 disk tray unit that requires attention, a trap is
asynchronously sent to the host, reporting the event. The host(s) to which a trap is
sent is configured by the user. The host software that receives the trap is an SNMP
management package.
The Sun StorEdge T3 disk tray uses the
/etc/syslog.conf
file to trigger the
SNMP trap. This file contains four levels of error warning to the administrator. For
instructions on how to set up SNMP notification for the Sun StorEdge T3 disk tray,
refer to the Sun StorEdge T3 Disk Tray Administrator’s Guide.
