3. Select the appropriate RAID level from the pull-down
list.
Note
The number of hard disk drives in the array
determines the RAID levels available for the
array.
If the array contains one hard disk drive, you
can select only RAID level-0 for the logical
drive.
If the array contains two hard disk drives,
you can select RAID level-0 or RAID level-1
for the logical drive.
If the array contains three or more hard disk
drives, you can select RAID level-0, RAID
level-1, or RAID level-5 for the logical drive.
4. Enter the Requested Space in the entry field.
The ServeRAID program uses the maximum available
space for the selected RAID level to calculate the
default value that it assigns.
Note
The actual logical drive size may be slightly
different from what you type in the Requested
Space field. The RAID level and the number of
hard disk drives determine the size of the logical
drive. For example, a disk array consisting of
three, 1 GB hard disk drives with a requested
RAID level-0 logical 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. Select OK to create the logical drive.
Notes
1. If you plan to use the Logical Drive Migration
(LDM) feature,
do not define more than seven
logical drives. The LDM feature requires one
free logical drive to perform the migration. Refer
to “Logical drive migration administration” on
page 109 for more information.
2. If you plan to use the Change RAID Level
function of the LDM feature, you must assign the
same RAID level to all logical drives within a
single disk array. Refer to “Change RAID levels”
on page 109 for more information.
Initializing logical drives:
Initializing a logical drive
erases the first 1024 sectors on the drive and prevents
access to any data previously stored on the drive.
To initialize a logical drive:
