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 107.
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.
