6-2 Adding Hotspare Disks
Hotspares are disk drives that are available to automatically replace failed drives in
a RAID 1 or RAID 10 virtual disk. Only global hotspares are supported for Embed-
ded MegaRAID Software.
To add a global hotspare disk, follow these steps:
1. In the left panel of the MegaRAID Storage Manager window, rightclick the icon
of any unused disk drive.
2. Select Make Global Hotspare.
Make sure the capacity of the hotspare drive is equal to or larger than the capacity
of the disks in the array and that it is the same type of drive (SAS or SATA).
Note: The hotspare drive will rebuild a failed drive even if it is SAS and the array
drives are SATA, or vice versa. Once the rebuilt is completed, It is recommended
that you replace the new array member with a drive of the same type.
12. Review the configuration shown in the window. If you want to change something,
click Back and change the configuration parameters.
13. Click Finish to accept the configuration and start the initialization process (unless
you selected No Initialization earlier).
