2. Select the disk array ID for which you want to create
a logical drive.
3. Select the RAID level that you want to assign to the
logical drive from the pull-down list.
The RAID levels available depend on the number of
hard disk drives that you select for the disk array.
Notes:
a. If you have one hard disk drive, the logical drive
can be only RAID level 0.
b. If you have two or more hard disk drives, the
logical drive can be RAID level 0 or 1.
c. If you have three or more hard disk drives, the
logical drive can be RAID level 0, 1, or 5.
d. If you plan to use the Change RAID Level
feature of logical drive migration, 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.
4. Type the size, in megabytes, that you want to assign
to the logical drive in the Requested Space entry
field.
Notes:
a. The Requested Space default value is calculated
as the maximum logical drive size available for
the RAID level assigned.
b. The Requested Space must be between 2 MB
and the maximum available.
c. The actual logical drive size that appears might
be slightly different from what you type in the
Requested Space field.
The size of a logical drive is determined by the
RAID level and the number of hard disk drives.
For example, a disk array consisting of three,
1 GB hard disk drives with a requested RAID
level 0 drive of 1000 MB will actually contain only
999 MB because the data is striped across all
three drives, with 333 MB on each drive.
5. Click on OK to create the logical drive.
6. You
must initialize all new logical drives before storing
data in them. Continue with “Initializing logical drives”
on page 36.
