Setting Up the Biggest Quadra
4.1. Setting the RAID Level
The LaCie Biggest Quadra is pre-configured at RAID
level 5, but it may be re-configured. The RAID level is set
using the RAID Level Switch Selectors on the rear panel of
the LaCie Biggest Quadra. The RAID level selectors consist
of two switches, with four possible switch position combina-
tions: RAID 0, 0 + 1, 5 and 5 + Hot Spare.
CAUTION: The LaCie Biggest Quadra must
be powered off to change the RAID level.
ImpOrTANT INfO: In the event that the
RAID level does not correspond to both the disk
settings and the RAID Level Switch Selectors, the
LCD will display the following two alternating
messages:
1. “RAID level”
“Unmatched”
2. “Current: Rx” (i.e. the current RAID level set-
tings of the installed disks)
“Original: Rx” (i.e. the RAID level settings on
the RAID Level Switch Selectors)
Example:
The RAID Level Switch Selectors are posi-
tioned to indicate a RAID 0 setting, but the
disks were set earlier as a RAID 5 array, the
LCD will display the following two alternating
messages:
1. “RAID Level”
“Unmatched”
2. “Current: R5”
“Original: R0”
In this situation, the array will not function.
There are two options:
1. Shut down the LaCie Biggest Quadra and
re-position the RAID Level Switch Selectors
to the previous RAID setting, in this case,
RAID 5.
2. Re-insert the four drives, and re-create the
array as a RAID 0 array. If there is any data on
the disks, it will be lost during the initializa-
tion.
CAUTION: If there is data on the array, chang-
ing the RAID level may lead to the loss of all of
the data on the array.
