Table 8. Physical disk actions

Action	Description

Rebuild	Regenerates all data to a replacement disk in a redundant virtual disk (RAID level
	1, 5, 6, 10, 50, or 60) after a disk failure. A disk rebuild normally occurs without
	interrupting normal operations on the affected virtual disk.
Replace Member	Replaces the disk in the virtual disk with another disk that can be selected.
LED Blinking	Indicates when physical disks are being used to create a virtual disk. You can
	choose to start or stop the LED blinking.
Force Online	Changes the state of the selected physical disk to online.
Force Offline	Changes the state of the selected physical disk so that it is no longer part of a
	virtual disk.

Make Global HS

Remove HS

Designates the selected physical disk as a global hot spare. A global hot spare is part of a pool for all virtual disks controlled by the controller.

Removes a dedicated hot spare from its disk group or a global hot spare from the global pool of hot spares.

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.

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/ storagecontrollermanuals.

The listed rates in the following table were taken during single disk failure with no I/O. 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.
