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 "
" 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 "
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:
Rescan — Checks whether any new array disks and other components such as fans or temperature probes have been
added to the enclosure.
Enable Alarm — Enables an audible alarm that sounds whenever the fault LED lights.
Disable Alarm — Turns off the audible alarm settings. If the alarm is already sounding, you can turn it off with this
command.
Set Tag Data — Allows you to enter or change asset information for the enclosure.
Download Firmware — Allows you to download firmware to the enclosure.
NOTE:
The Download Firmware command is only available on the PowerVault 220S and PowerVault 221S
enclosures.
Enclosure Properties — Displays enclosure properties.
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,
