cables (see Section 2.2, step 5).
NOTE: The failed drive must be replaced with a drive of identical model and capacity if
being used in a RAID 0 or RAID 1.
If the Mercury Elite Pro Dual is set up as a span or as a RAID 0, the array must be reformat-
ted before it can be used again. If the Mercury Elite Pro Dual is set up in independent
drive mode, you do not need to reformat the existing drive or the new drive. If the new
drive had data on it before being installed in the Mercury Elite Pro Dual, that data will
remain intact. See Section 2.4.2 for information on rebuilding after drive replacement
in a RAID 1.
2.4.2 Rebuilding a RAID 1
After the failed drive is replaced, if the Mercury Elite Pro Dual is configured as a RAID 1,
the array will automatically begin the rebuild process when it is turned on. This process
may take from several hours up to more than a day, based on the capacity of the drives.
During the rebuild process, the power LED will pulse blue slowly. It is recommended to
leave the Mercury Elite Pro Dual turned on during the entire rebuild process, but if power
is interrupted, the unit will continue rebuilding automatically when power is restored.
Once the rebuild process is complete, the power LED will resume normal activity. See
Section 1.4 for more information on the behavior of the LEDs on the front of the Mer-
cury Elite Pro Dual.
NOTE: The Mercury Elite Pro Dual needs an active data signal to remain on. If it goes to
sleep, if it is disconnected from the computer, or if the computer goes to sleep or turns
off, the Mercury Elite Pro Dual will turn off. In order to minimize the total rebuild time, it is
recommended to keep the Mercury Elite Pro Dual connected to the computer, keep the
computer turned on, and disable any hard drive sleep settings on the computer for the
duration of the rebuild process.
