Creating a Global Hotspare Drive

The MegaRAID BIOS CU enables you to create global hotspare drives (dedicated hotspare drives are not supported). A hotspare drive can automatically replace a failed drive in a redundant RAID 1 or RAID 10 array, to protect against data loss.

WARNING: When you select disk drive for a global hotspare, be sure it is the same type of drive (either SAS or SATA) as the drives in the arrays that it will protect. It is recommended that you do not combine SAS and SATA drives in the same array.

You can create a hotspare when you are configuring a new storage configuration, as described in the previous sections.

Adding a Hotspare Drive

To add a hotspare drive to an existing redundant storage configuration, use the following steps:

1.Select OBJECTS from the MANAGEMENT menu.

2.Select PHYSICAL DRIVE.

A list of physical drives appears.

3.Select an un-configured drive or READY drive from the list, and press ENTER.

4.When the PHYSICAL DRIVE PROPERTY menu appears, select MAKE HOT SPARE and press ENTER.

5.Select YES from the pop-up menu to create the hotspare drive.

Removing a Hotspare Drive

To remove a hotspare drive

1.Select OBJECTS from the MANAGEMENT menu.

2.Select PHYSICAL DRIVE.

A list of physical drives appears.

3.Select the HOTSP disk and press ENTER

4.Select FORCE OFFLINE and press ENTER.

The status of the drive changes to READY, and it can then be used in another new array.

Initializing Virtual Drives

WARNING: When you initialize a virtual drive all existing data on the virtual drive is erased.
