Dell PowerVault 745N - Manual (Page 49)

The temperature probes that are installed in the enclosure are displayed under Temperature Probes in the tree view. You can select Temperature Probes to
display the individual temperature probes and their status information in the right pane. The status information includes the current temperature in Celsius
and the warning and error thresholds for the temperature probe. The error threshold has a default value that cannot be changed. However, you can set the
warning threshold. See the Set Thresholds for Temperature command in "
Enclosure Commands " for information on setting the warning threshold.
Right-clicking Temperature Probes in the left pane displays a context menu with a Properties option. You can also expand Temperature Probe to display the
individual temperature probes in the tree view. Right-clicking an individual temperature probe also displays a context menu with a Properties option. This
option enables you to set the minimum and maximum warning threshold for the selected temperature probe.
Enclosure Commands
This section describes the commands associated with the enclosure and its fans, power supplies, and temperature probes. For the commands associated with
the array disks in an enclosure, see "
Disk Commands ."
Right-clicking an enclosure object in the tree view displays a context menu with the enclosure commands. Right-clicking the enclosure's fans, power supplies,
and temperature probes also displays a context menu for each of these components.
The enclosure's context menu items can vary depending on the model of the enclosure. The enclosure context menu might include any of the following
commands:
l Rescan — Checks whether any new array disks and other components such as fans or temperature probes have been added to the enclosure.
l Enable Alarm — Enables an audible alarm that sounds whenever the fault LED lights.
l Disable Alarm — Turns off the audible alarm settings. If the alarm is already sounding, you can turn it off with this command.
l Set Tag Data — Allows you to enter or change asset information for the enclosure.
l Download Firmware — Allows you to download firmware to the enclosure.
l Enclosure Properties — Displays enclosure properties.
l Set Thresholds for Temperature — Sets the minimum and maximum values for the temperature warning threshold. This command is located on the
context menu for the individual temperature probes, not on the main context menu.
Disk Management
This section describes conceptual and procedural information about how to implement basic and dynamic disks using Array Manager.
Monitoring Disk Reliability
Array Manager supports Self-Monitoring Analysis and Reporting Technology (SMART) on array disks that are SMART enabled.
SMART performs predictive failure analysis on each hard drive and sends an alert if a hard disk failure is predicted. The RAID controllers check the array disks
for failure predictions. If the RAID controller predicts a failure, it passes the information to the Array Manager. Array Manager immediately displays an alert icon
for the hard drive, raises an alert under the Events tab, and puts an alert message in the Windows Storage Server 2003 Event Log.
Managing Volumes Using Disk Management
This section describes how to use the Windows Disk Management tool to manage basic and dynamic volumes.
NOTE: The Download Firmware command is only available on the PowerVault 220S and PowerVault 221S enclosures.
NOTE: The supported PERC controllers do not report SMART alerts for unassigned or hot-spare hard drives. Also, when you pause controller I/O, the
controller does not send SMART alerts or events.
