3.2. Changing the RAID Mode
The 4big comes preconfigured in RAID 5 mode. Before you change
the RAID mode of the LaCie 4big, familiarize yourself with the 4big’s
RAID modes. See section
3.1. About RAID Modes
.
To change the RAID mode:
1. Unmount or safely remove the 4big Quadra volumes from your
computer, disconnect the interface cable and switch off the
4big.
2. To enter RAID modification mode, turn ON the 4big (do not
select “AUTO”) and simultaneously press the front LED button
for 15 seconds. The front LED will blink blue and red.
3. Push the + or - buttons on the RAID mode selector until the
desired RAID number appears (
Fig. 14
).
NOTE:
0=RAID 0, 1=RAID 10, 2=Concatenation, 3=RAID 3,
4=RAID 3+Spare, 5=RAID 5, 6=RAID 5+Spare, 7=N/A.
NOTE:
Although the number 7 appears in the RAID selector, no
RAID changes will take effect if 7 is selected.
4. Validate the mode by pushing the front LED button. The 4big
will start.
5. Connect the 4big’s interface cable. The device is ready to be
reformatted (see section
3.4. Formatting and Partitioning
).
IMPORTANT INFO:
You must partition the disk drives after
changing the storage policy configuration. See section
3.4. Format-
ting and Partitioning
.
IMPORTANT INFO:
Changing the RAID mode or encryption con-
figuration destroys data stored on the LaCie 4big. If you have saved
data on the drives, back it up before following these steps.
IMPORTANT NOTE:
If you have encrypted your 4big, changing
the RAID mode will not change the encryption configuration (includ-
ing login name and password) but will erase the encrypted data.
