LaCie Biggest S1S
User’s Manual
4.1. Setting The RAID Level
The LaCie Biggest S1S 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 S1S. The RAID level selectors consist of two switches, with four
possible switch position combinations: RAID 0, 0 + 1, 5 and 5 + Hot Spare.
Caution!
The LaCie Biggest S1S must be powered off to change the RAID level.
Caution!
If there is data on the array, changing the RAID level may lead to the loss of all of the data on the array.
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 settings 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 positioned 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 S1S 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 initialization.
