Chapter 5: Protecting Your Data 56
Assigning a Dedicated Hot Spare or Pool Hot Spare
A dedicated hot spare is assigned to one or more specific logical drives. (A dedicated hot spare
that has been assigned to protect more than one logical drive is called a pool hot spare.)
Note:
You must create the logical drive before you can assign a dedicated hot spare.
To assign a dedicated or pool hot spare:
1 In the Enterprise View, click the controller on which you want a dedicated hot spare.
2 In the Physical Devices View, click the disk drive you want to designate as a hot spare. (See
Hot Spare Limitations on page 55 for help selecting a disk drive.)
3 In the menu bar, select Actions, then click Create dedicated hot-spare drive for, then click
the name of the logical drive (in this example, Device 1).
A plus sign appears beside the selected disk drive, indicating that it’s designated as a
dedicated hot spare. (A yellow plus sign indicates an error. See What Do the Hot Spare Icons
Mean? on page 56 for help solving the problem.)
4 To use the same dedicated hot spare to protect another logical drive (create a pool hot
spare), repeat Step 2 and Step 3.
