204 Physical Disks or Physical Devices
Global hot spares must be assigned and unassigned manually. They are not
assigned to specific virtual disks. If you want to assign a hot spare to a virtual
disk (it replaces any physical disk that fails in the virtual disk) then use the
Assign and Unassign Dedicated Hot Spare.
NOTE: When deleting virtual disks, all assigned global hot spares may be
automatically unassigned when the last virtual disk associated with the controller is
deleted. When the last virtual disk of a disk group is deleted, all assigned dedicated
hot spares automatically become global hotspares.
NOTE: For PERC H310, H700, H710, H710P, H800, and H810 controllers, if any of the
drives you selected is in the spun down state, the following message is displayed:
The current physical drive is in the spun down state. Executing this task on this
drive takes additional time, because the drive needs to spun up.
CAUTION: The SAS 6/iR controller enables you to assign two physical disks as
global hot spare. Assigning a physical disk as a global hot spare on a SAS 6/iR
controller is likely to cause data loss from the physical disk. If the system or boot
partition resides on the physical disks, it may be destroyed. You should only
assign physical disks that do not contain critical data. For more information about
global hot spares and the SAS 6/iR, see Global Hot Spare Considerations on a SAS
6/iR.
You should be familiar with the size requirements and other considerations
associated with hot spares. For more information, see the following:

Does my controller support this feature? See Supported Features.
The Online and Offline tasks only apply to physical disks that are included in
a redundant virtual disk and attached to a PERC 4/SC, 4/DC, 4e/Si, 4e/Di,
4e/DC, or 4/Di controller.
