2.4.1 Drive Replacement
If the drive was part of a RAID 1, it can be replaced and the array will be rebuilt. In
the meantime, the data will remain accessible through the other drive in the RAID
1. If the Mercury Elite Pro Dual was purchased with drives already installed and
it is still under warranty, see Section 3.6 for information on how to contact OWC
technical support to arrange for replacement.
If the warranty has expired or if the Mercury Elite Pro Dual was purchased without
drives, follow the assembly instructions in Section 2.2 to access and replace
the failed drive. If the HDD2 LED is blinking red, the failed drive is the one on the
bottom, connected directly to the black SATA connector on the circuit board (see
Section 2.2, step 4). If the HDD1 LED is blinking red, the failed drive is the one on
the top, connected using 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 reformatted before it can be used again. If the device 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 device is congured 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 Mercury 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 o, the device will turn o. To minimize the total rebuild time, it is
recommended to keep the device connected to the computer (with the computer
powered on), and disable any hard drive sleep settings on the computer for the
duration of the rebuild process.
