Configuration : Creating Hot Spares

Creating Hot Spares

Hot spares are drives that are available to automatically replace failed drives in a redundant virtual drive (RAID 1, 5, 6, 10, 50, 60). There are two kinds of hot spares:

n

Dedicated hot spares, which are available for a specified drive group

n

Global hot spares, which are available to any drive group defined on the controller

 

* 

NOTE The capacity of the drives you assign as dedicated hot spares should be equal to or greater than the capacity of the other drives in the drive group.

To create a global hot spare, follow these steps:

1.

Select the Physical tab in the left panel of the MegaRAID Storage Manager main menu screen and click the icon of an unused drive.

For each drive, the screen displays the port number, enclosure number, slot number, drive state, drive capacity, and drive manufacturer.

2.

Select either Go To>>Physical Drive>>Assign Global Hot Spare or Go To>>Physical Drive>>Assign Dedicated Hot Spare.

If you selected Assign Dedicated Hot Spare, select a drive group from the list that appears. The hot spare is dedicated to the drive group that you selected.

* 

If you selected Assign Global Hot Spare, skip this step, and go to the step 4. The hot spare is available to any virtual drive on a specific controller.

3.

Click Go to create the global hot spare.

The drive state for the drive changes to dedicated hot spare or global hot spare, depending on your selection.
