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:

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,
