Creating Hot Spares
Hot spares are drives that are available to automatically replace failed drives in a virtual drive. There are two kinds of hot spares: 1) dedicated hot spares, which are available for a specified drive group, and 2) global hot spares, which are available to any drive group defined on the controller.
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:
- Select the Physical View tab in the left panel of the MegaRAID Storage Manager window,
- Select the icon for any drive that is not already part of a drive group.
For each drive, the screen displays the port number, enclosure number, slot number, drive state, drive capacity, and drive manufacturer.- In the right panel of the MegaRAID Storage Manager window, select the Operations tab.
- Select Make Global Hotspare.
- Click Go to create the global hot spare.
The drive state for the drive changes to global hot spare.You normally create a dedicated hot spare when you create a new configuration (see Creating a New Configuration). To add a dedicated hot spare to an existing drive group, follow these steps:
- In the left panel of the MegaRAID Storage Manager window, click the icon of a drive that is not already assigned to a storage configuration. (A check mark appears on the drive icon if it is already assigned.)
- In the right panel, click the Operations tab and select Make Dedicated Hotspare.
- Select the drive group from the list that appears in the right frame.
The hotspare will be dedicated from the drive group you selected.- Click Go to create the dedicated hotspare.
The drive state for the drive changes to hot spare.
