The Select RAID Level pop-up window appears. Notes 1. Typically, the first logical drive that you define will be the startup (boot) drive. 2. The ServeRAID Configuration program automatically assigns RAID level 0 to any logical drives defined in an array containing only one hard disk drive. When this is the case, the Select RAID Level pop-up window will not appear. 3. If you have two hard disk drives in the array, the Select RAID Level pop-up window appears, but RAID level 5 is not available. You need at least three hard disk drives in an array to assign RAID level 5 to the logical drives. 4. The RAID level that you assign to a logical drive can influence the amount of space that the drive requires; therefore, you must assign a RAID level before you enter the size of the logical drive. 5. For a description of RAID levels 0, 1, and 5, see "RAID classifications" on page 82. 6. You can define up to eight logical drives for the array. If you plan to use the logical-drive migration (LDM) procedure, do not define more than seven logical drives. The LDM procedure requires one free logical drive. (See "Logical drive migration administration" on page 38 for more information.) 7. If you plan to use the Change RAID Level feature of the LDM, you must assign the same RAID level to all of the logical drives in the array. (See "Changing RAID levels" on page 39 for more information.) 3. Use the Up Arrow (↑) or Down Arrow (↓) key to highlight the RAID level that you want to assign to the logical drive; then, press Enter. The Logical Drive Size pop-up window appears. If this is the first logical drive you are defining, the Logical Drive Size pop-up window will show the amount of free space available in the array. Note Typically, the first logical drive that you define will be the startup (boot) drive. If you already defined other logical drives for this array, the Allocation Table appears showing the existing logical drive sizes and the amount of free space available. 106 Netfinity Server HMM

The Select RAID Level pop-up window appears.
Notes
1.
Typically, the first logical drive that you
define will be the startup (boot) drive.
2.
The ServeRAID Configuration program
automatically assigns RAID level 0 to any
logical drives defined in an array containing
only one hard disk drive.
When this is the
case, the Select RAID Level pop-up window
will not appear.
3.
If you have two hard disk drives in the array,
the Select RAID Level pop-up window
appears, but RAID level 5 is not available.
You need at least three hard disk drives in
an array to assign RAID level 5 to the logical
drives.
4.
The RAID level that you assign to a logical
drive can influence the amount of space that
the drive requires; therefore, you must
assign a RAID level before you enter the
size of the logical drive.
5.
For a description of RAID levels 0, 1, and 5,
see “RAID classifications” on page
82.
6.
You can define up to eight logical drives for
the array.
If you plan to use the
logical-drive migration (LDM) procedure, do
not define more than seven logical drives.
The LDM procedure requires one free
logical drive.
(See “Logical drive migration
administration” on page
38 for more
information.)
7.
If you plan to use the Change RAID Level
feature of the LDM, you must assign the
same RAID level to all of the logical drives
in the array.
(See “Changing RAID levels”
on page
39 for more information.)
3.
Use the Up Arrow (
↑
) or Down Arrow (
↓
) key to
highlight the RAID level that you want to assign to the
logical drive; then, press
Enter.
The Logical Drive
Size pop-up window appears.
If this is the first logical drive you are defining, the
Logical Drive Size pop-up window will show the
amount of free space available in the array.
Note
Typically, the first logical drive that you define will
be the startup (boot) drive.
If you already defined other logical drives for this
array, the Allocation Table appears showing the
existing logical drive sizes and the amount of free
space available.
