Table 1. Physical disk actionsPhysical 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	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.
Remove HS	Removes a dedicated hot spare from its disk group or a global hot spare from the global pool of hot spares.
