3.2. Changing the RAID Mode
Before you change the RAID mode of the LaCie 2big, familiarize
yourself with the 2big’s RAID modes. See section
3.1. About RAID
Modes
.
To change the RAID mode:
1. Unmount or safely remove the 2big Quadra volumes from your
computer, disconnect the interface cable, and switch off the
2big.
2. To enter RAID modification mode, push and hold the front but-
ton and simultaneously turn on the 2big. The front LED will blink
blue and red.
3. Use the 2-in-1 tool to push the RAID selection button until the
light arrives in front the desired RAID mode. The LED of the
selected mode will blink until you validate it (next step) (
Fig. 11
).
4. Validate the mode by pushing the front LED button. The 2big
will start.
5. Connect the 2big’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
.
CAUTION:
Your LaCie 2big comes preconfigured in Fast (RAID 0)
mode. Fast mode allows access to the whole storage capacity and
enhanced transfer speeds. However, Fast mode does not provide
data security in the event of disk failure. LaCie recommends Mixed
mode in order to take advantage of RAID 0 performance with the
option to back up all data on the RAID 1 partition. See section
3.1.
About RAID Modes
, for more information.
IMPORTANT INFO:
Changing the RAID mode or encryption con-
figuration destroys data stored on the LaCie 2big. If you have saved
data on the drives, back it up before following these steps.
IMPORTANT NOTE:
If you have encrypted your 2big, changing
the RAID mode will not change the encryption configuration (includ-
ing login name and password) but will erase the encrypted data.
