Rebuild

Select Rebuild to rebuild one or more failed physical disks. For information on performing a physical disk rebuild, see the
topic Performing A Manual Rebuild Of An Individual Physical
Several of the controller configuration settings and the virtual disk settings affect the actual rate of rebuild. The 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 at dell.com/support/manuals.
The listed rates in the following table were taken during single disk failure with no I/O present on a PERC H810 card
connected to a single PowerVault MD1220 enclosure. Rates vary depending on type, speed and number of hard drives
present in array; as well as which controller model and enclosure configuration are being used.
