5.3.2 Halted: RAID Invalid/Degraded
This error occurs when the RAID has encountered a problem, most likely caused by bad
sectors or a dead drive. This error will prompt a visual confirmation on the LCD and a
steady System access LED to the right of the LCD. There are different steps to follow
depending on what RAID type the drives are configured in.
5.3.2.1 RAID Invalid: Spanning
There is no data protection in Spanning, you will have to build a new RAID. Remove the
DualPAK and replace the failed drive, preferably with the same model of drive. Open
Configurator to set up a new RAID. (see section 4.1.2)
5.3.2.2 RAID Invalid: RAID 0
There is no data protection in Spanning, you will have to build a new RAID. Remove the
DualPAK and replace the failed drive, preferably with the same model of drive. Open
Configurator to set up a new RAID. (see section 4.1.2)
5.3.2.3 Degraded: RAID 1
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.
NOTE: A degraded RAID 1 will stay mounted and can continue to transfer data. How-
ever, CRU-DataPort recommends disconnecting the unit during a rebuild if at all possible.
