Rebuild
Select Rebuild to rebuild one or more failed physical disks. For information
on performing a physical disk rebuild, see "Performing a Manual Rebuild of an
Individual Physical Disk" on page 108.
If no workload is placed on the storage subsystem, the controller rebuilds SAS
drives at a rate of approximately 200 GB/hour and SATA drives at a rate of
approximately 100 GB/hour. Several of the controller configuration settings
and the virtual disk settings affect the actual rate of rebuild. These factors
include the rebuild rate setting, virtual disk stripe size, virtual disk read policy,
virtual disk write policy, and the amount of workload placed on the storage
subsystem. For information on getting the best rebuild performance from
your RAID controller, see the documentation on Dell Support website at
support.dell.com.
Controller Management (Ctrl Mgmt)
The Controller Management screen (Ctrl Mgmt) displays the product name,
package, BIOS version, firmware version, BIOS Configuration Utility version,
and boot block. Use this screen to perform actions on the controller and
BIOS. You can perform functions such as enable or disable the controller
BIOS, and the BIOS during bootup in event of BIOS errors. In addition, you
can select a virtual disk from which to boot, select default settings, and reset
the configuration.
