number that is closest to or lower than 2000 and divisible by 3 is
1998. The logical drive size is 999, which is 50% of the physical
capacity.
Scenario 3
The array consists of three 1 GB drives and you assign RAID
level 5. Data is striped across all three drives in the array, but
the space equivalent to that of one drive is used for redundant
storage. Therefore, if you type
1ððð MB
, the number in the Size
(MB) field remains 1000 because it is divisible by 2 (drives),
which is the space available for data.
If you do not use the entire array for this logical drive, you can
create another by assigning either the same or a different RAID
level for an additional logical drive. You can have as many as
eight logical drives among eight disk arrays.
7. To define more logical drives, repeat steps 1 through 6 of this
procedure.
8. To leave this screen, select Exit or press Esc.
9. To ensure that your server operates correctly, you must select
Initialize Logical Drive for proper operation. This sets the
drive to a predetermined state. The initialization process
overwrites any data on the drive with zeros.
a. Select Initialize/Synchronize Log Drive from the Main
Menu, then select Initialize Logical Drive.
b. Select the logical drives you want to initialize from the
Logical Drive list by pressing the Spacebar (the selected
drives will appear highlighted). To start the initialization,
press Enter. The Confirm pop-up window appears, asking
you to confirm your action.
Attention
: If you select Yes in the Confirm pop-up
window, information in the logical drive will be overwritten
with zeros.
