5.3.2.6 Degraded: RAID 10
The loss of a drive in a RAID 1 will result in a degraded RAID state. The LCD display will
show a “Degraded” state and the RAID LED (yellow) will flash. The RAID can be rebuilt
by powering down the DataPAK and replacing the failed drive, preferably with the same
model of drive. After the new drive is installed power up the DataPAK and wait for
DataPAK to initialize. When the DataPAK has initialized the LCD display will prompt you
to “Add new disk.” Select “yes” (left) and it will being to rebuild the RAID. There will be a
timer in the bottom right corner of the LCD that will give an approximate time to comple-
tion. After the rebuild is finished the DataPAK will need to be rebooted. A rebuild with
500GB drives will take approximately 1.5 hours.
The loss of two drives will result in a RAID failure. New drives will need to be inserted,
preferably the same model of the drives that are getting replaced. Open Configurator 3.0
to set up a new RAID. (see section 4.1.2)
NOTE: A degraded RAID 10 will stay mounted and can continue to transfer data. How-
ever, CRU-DataPort recommends disconnecting the unit during a rebuild if at all possible.
