Configuration Client:
The Configuration Client is a powerful
module that runs as an independent program from RAIDWatch
and can be installed on different hosts. It is used for event
notification via email, fax, LAN broadcast, SNMP traps, MSN
Messenger, ICQ, SMS (Short Message Service), and the
configuration utility screen. The Configuration Client helps
prevent blind time and keeps you constantly informed as to the
status of the storage management subsystem. Instructions on
activating the Configuration Client functionality are given in the
RAIDWatch User’s Manual
.

LEDs:
Device status indicating LEDs are placed on all the ES
active components. These LEDs are used to inform users of the
integrity of a given component or of a given FC link. You should
become familiar with the different LEDs that are present on the
subsystem and be aware of their functions. (See
Section 3.2
)
•
Audible alarm:
An audible alarm is present on the subsystem
controller board and will be triggered if any of a number of
threatening events occur. These events usually jeopardize the
functional and operational integrity of the controller board and
must be heeded at all times. Events such as a breach of the
temperature threshold will trigger the alarm and if an onsite
subsystem manager is present, the manager should use either the
LCD panel or the PC hyper-terminal to determine the cause of the
alarm and take the appropriate corrective measures. (See
Section
3.3
)

I
2
C:
The I
2
C bus monitors the operational integrity of the PSUs,
cooling modules, voltage readings, and RAID controller board
temperature. (See
Section 3.4
)
Subsystem monitoring is a necessary part of subsystem management. If
failure events or other disruptive events are detected and reported, the
subsystem managers must take the appropriate action to rectify the problem.
Failure to act in a properly specified manner to a system event (like
overheating) can cause severe and permanent damage to the subsystem.
3.2. Status-indicating
LEDs
3.2.1 Brief Overview of the LEDs
The GALAXY has status-indicating LEDs distributed over the active
components that inform subsystem managers about each component
operational status. The list in
Table 3-1
shows the number of LEDs assigned
to each component.
