Setting Up the Biggest Quadra
4.1. Setting the RAID Level
e LaCie Biggest Quadra is pre-configured at RAID
level 5, but it may be re-configured. e RAID level is set
using the RAID Level Switch Selectors on the rear panel of
the LaCie Biggest Quadra. e RAID level selectors consist
of two switches, with four possible switch position combina-
tions: RAID 0, 0 + 1, 5 and 5 + Hot Spare.
CAUTION: e 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:
e 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.
ere 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.
