Figure 56. Delete Array Warning Message
When you click Yes, watch the Logical Configuration structure in the Logical
Configuration Panel (left side) to verify that the selected array icon is removed
from the configuration. Also, watch the drives from the deleted array in the
Physical Elements Panel (right side) to verify that the blue light, on the bottom
side of the affected drives, turns off. This means that these drives are now
available to be used in a new array configuration. They may also be marked as
hot-spares.
Assigning a Dedicated Hot-Spare
The advantage of assigning a dedicated hot-spare to a selected array (see the drive
with the "S" and the circle) is to ensure priority response time in the event of a
failed drive and failed array condition. Since the system will search and use a
dedicated hot-spare first, it is a good safety practice to build a dedicated hot-spare
option into your configuration. Two methods are available to create a dedicated
hot-spare: (1) Assigning a Dedicated Hot-Spare while Creating an Array or (2)
Assigning a Dedicated Hot-Spare after Creating an Array. When you click on the
array icon, the disk drives associated with the icon will be lit up with the blue
light ON in the Physical Elements Panel (see
Figure 57 ).
When other gray drives in the enclosure have the blue light on, it means they are
associated with a different array that is not selected. In order to see an available
drive in the enclosure, the drive and the light will be gray. In the example below
(see
Figure 57 ), there are the following: one failed drive, six gray drives with the
light on, three blue drives with the light on plus the dedicated spare to that array,
five gray drives with no light ( these drives are available), and three global spares.
