Configuring and Managing RAID

Physical Disk Actions

Table 6-6 describes the actions you can perform on physical disks.

For procedures that can be used to perform the actions, see "Physical Disk

Management" on page 108.

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 111.
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 on Dell Support website at support.dell.com/manuals.

longer part of a virtual disk.

A global hot spare is part of a pool for all virtual disks

controlled by the controller.
