RAIDWatch Manager
3.4. RAIDWatch Manager
The RAIDWatch Manager enables users to manage and maintain the RAID Controllers
using their web browsers. The Ethernet port at the back of each controller module enable
users to use a LAN cable to connect to the subsystem.
The RAIDWatch Panel View is a specialized customization that shows a direct
representation of the ES U16U in the content panel of the RAIDWatch screen. The Panel
View allows users to quickly determine the operational status of critical ES U16U
components. Please refer to the RAIDWatch manual for further details.
NOTE:
The RAIDWatch User’s Manual can be found on the CD-ROM that came
with the system. To access the RAIDWatch User’s Manual please refer to this file.
3.5. Notification Processing Center (NPC)
The NPC is a powerful module that runs as a background
Disk and Executive Monitor
(DAEMON) independent from RAIDWatch that can, itself, be installed redundantly on
different hosts. It is used for event notification over Email, LAN broadcast, and SNMP
traps. It helps to prevent blind time and keeps a user constantly informed as to the status
of the storage management subsystem. The NPC functionality can be activated and the
instructions are given in the
RAIDWatch User’s Manual
.
NOTE:
The RAIDWatch User’s Manual can be found on the CD-ROM that came
with the system. To access the RAIDWatch User’s Manual please refer to this file.
3.6. Audible Alarm
Different controller environmental and operational parameters (like temperature etc.)
have been assigned a range of values between which they can fluctuate. If either the
upper or lower thresholds are exceeded, an audible alarm will automatically be triggered.
The alarm will also be triggered when an active component of the ES U16U subsystem
fails. If the ES U16U subsystem manager is onsite and is alerted by the alarm, to
determine what has triggered the alarm the user will have to read the error message on the
LCD screen or on the PC terminal. After determining what has occurred the ES U16U
subsystem manager must take appropriate actions to rectify the problem.
WARNING:
If an alarm is triggered it is necessary for the user to determine the problem. If the
audible alarm is ignored or not taken seriously and the problem is not rectified,
permanent damage to the system can result.
3.6.1 Default Threshold Values
Table 3-7
shows the default threshold values for the ES subsystem. If any of these values
are surpassed the alarm will sound:
