■4.1.1. RAID 5

This is the default setting of the LaCie Biggest

Fig. 4.1.1

CAUTION: In a RAID 5 array, in the event that a disk needs to be replaced, always replace the failed disk with the LaCie Biggest Quadra’s power on. Do not turn the LaCie Biggest Quadra’s power off; doing so may lead to the loss of the data on the array.

■4.1.2. RAID 5 + Hot Spare

1.Power off the LaCie Biggest Quadra.

2.Move switch 1 of the RAID Level Switch Selectors to the OFF position. Move switch 2 of the RAID Level Switch Selectors to the ON position.

Important Info: In a RAID 5 + Hot Spare array, the disk in the top drive bay is desig- nated as the Hot Spare (the default setting), and the Disk Status Indicator will light in amber to indicate this configuration.

Fig. 4.1.2

Technical note: In the initial configura- tion of a RAID 5 + Hot Spare array, the top drive bay (Drive Bay 1) is the default Hot Spare (the Disk Status Indicator will be amber). In the event that a disk fails, the Hot Spare position will change.

For example, if the disk in Drive Bay 3 fails, then the Hot Spare disk in Drive Bay 1 will be re-built and will no longer be the Hot Spare. Instead, when you place a new disk in Drive Bay 3, it will become the new Hot Spare, and will be indicated by the amber Disk Status Indicator.
