Buffalo TS5600D2406 [38/176] Configuring a hot spare

8 Select a RAID mode and the drives to be used, then click Create RAID Array.

Note: Normally, after a RAID array is created, it is "resynced", which optimizes the array, making it more stable.

The resyncing process takes about 1 hour per terabyte of space in the array. File transfers will be slower

during this period, but the array will remain fully usable. The I17 message will be shown on the LCD display

during the resync. If you uncheck "Resync after creating the RAID array", the resync will be skipped. This is not

recommended for RAID 5 arrays, which should always be resynced. Resyncing is not needed for RAID 0 arrays. If

the TeraStation is rebooted during the resyncing process, the resync will begin again from the beginning.

9 Step through the wizard to create the array.

Notes:

• You can also configure RAID settings from Easy Admin.

• After changing the RAID mode, create a shared folder.

Configuring a Hot Spare

If you have a hot spare configured and an array fails, the TeraStation immediately switches over to the hot spare. To

use a hot spare, you need an extra drive that's not part of any array and a RAID 1, RAID 10, RAID 5, RAID 51, or RAID 6

array.

Notes:

• All data on the hot spare drive is deleted when it is configured as a hot spare and again when it changes from

a spare to a drive in the array.

• A hot spare cannot be configured for TeraStation models with only two hard drives. Use RAID 1 instead.

1 In Settings, click Drives.

2 Click to the right of "RAID".
