LaCie Biggest F800
User’s Manual
The Problem
I was creating a RAID 5 array, and a
disk failed. What should I do?
I only have two or three disks. Can I
still create a RAID array?
The LCD Display reads “unmatched.”
Possible Answers
Replace the failed disk with another disk of equal or greater capacity. The array
will re-initialize when the failed disk is replaced and the process is restarted.
The LaCie Biggest F800 cannot create an array from just two disks. If you only
have three disks, you can only create a RAID 5 + Hot Spare array. The three disks
must be installed in the bottom three Drive Bays, with the top Drive Bay (the Hot
Spare location) empty.
The RAID Level Selector Switch is not set to the level of the existing array. 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 F800 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.
