8. Highlight RAID and press ENTER.
A list of the available RAID levels for the current virtual drive appears.
9. Select a RAID level for the virtual drive and press E
NTER.
10. (Optional) You may also set the logical drive size by highlighting SIZE and then
pressing E
NTER.
The minimum valid virtual drive size is 64 Mbytes. An error will appear if you try to
create a virtual drive that is smaller 64 Mbytes.
By default, all the available space in the array is to the current virtual drive. For
RAID 10 arrays, only one virtual can be defined for the entire array.
11. (Optional) You may change the disks’s default Write Cache and Read Ahead
policies (see Section 4-3: "Setting the Hard Disk Write Cache and Read Ahead
Policies" on page 4-9).
12. When you have finished defining the current virtual drive, select A
CCEPT and press
E
NTER.
13. Configure additional virtual drives on the same array, if desired.
If you have created more than one array, configure a virtual drive on the second
array.
14. Save the configuration when prompted, and press any key to return to the
M
ANAGEMENT menu.
15. Initialize the new virtual drive(s). (See "Initializing Virtual Drives" on page 4-7 for
detailed instructions.)
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.
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 O
BJECTS from the MANAGEMENT menu.
2. Select PHYSICAL DRIVE.
A list of physical drives appears.
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.
