Dell PowerVault 775N (Rackmount NAS Appliance) - Manual (Page 54)

You cannot extend a volume if any of the following are true:
The volume is formatted as FAT or FAT32.
The volume is using software RAID (striped, mirrored, or RAID 5 volume).
Unallocated space is not available on a dynamic disk.
You can extend simple and spanned volumes on dynamic disks onto a maximum of 32 dynamic disks. After a volume is
extended, it cannot be mirrored or striped using software RAID. No portion of a spanned volume can be deleted without
deleting the entire spanned volume.
1. Right-click the simple or spanned volume you want to extend, and then click Extend Volume.
The selected volume appears in the dialog box along with its current size.
2. Enter the amount to extend the volume, and then click OK.
Ignore any system messages that you might see while the volume extends. You do not have to run any special utilities.
3. Click OK.
The volume now shows the size of the extended volume.
Enclosure Management
The PERC 3/DC and PERC 3/QC controllers support enclosure management. Array Manager displays the properties of the
enclosure's fans, power supply, and temperature probes. Array Manager also notifies you of enclosure status changes through
events that are displayed on the Events tab and logged in the Windows Powered Event Log.
Enclosure Components in the Tree View
When you expand a storage subsystem in the Array Manager tree view in the left pane, you see the controllers that are
attached to the storage subsystem. You can expand the controller to display the controller's channels. Expanding an
enclosure channel displays the enclosure's fans, power supply, and temperature probes. Each of these objects expands to
display the individual fans, power supplies, and temperature probes within the enclosure.
Thermal Shutdown
Enclosure management provides a feature which automatically shuts down the operating system, the server, and the
enclosure when the enclosure's temperature reaches dangerous temperature extremes. The temperature when shutdown
occurs is determined by the enclosure temperature probe's Minimum Error Threshold and the Maximum Error
Threshold. These thresholds are default settings that cannot be changed.
Enclosure Fans
The fans that are installed in the enclosure are displayed under Fans in the tree view in the left pane. You can select and
expand Fans to display the individual fans and their status information in the right pane. You can also expand Fans to
display the individual fans in the left page.
If you right-click the Fans object or an individual fan, a context menu is displayed with a Properties option.
Enclosure Power Supplies
The power supplies that are installed in the enclosure are displayed under Power Supplies in the tree view. Select Power
Supplies in the left pane to display the individual power supplies and their status information in the right pane. You can also
