To replace a failed drive, go to the local user interface at http://x.x.x.x, where x.x.x.x is the IP
address of your CloudStation. See which drive failed. Turn off the CloudStation and replace the
bad drive. Turn the CloudStation back on and let it boot up. In the local user interface, click on
After replacing the drive, click here . The array will be rebuilt.
To remove a drive that has not failed, put the drives into Independent mode. In the local user
interface, select that drive to remove and click on
remove disk . Power down the CloudStation and
physically remove the drive.
In
Independent Mode
, the disks are independent. They may contain different data. The full
capacity of both drives is usable. There is no redundancy. If a drive fails, all data on that drive is
lost.
In
RAID 1
, disk mirroring provides fault tolerance but also decreases overall capacity. An array of
drives is created and the system saves the data to both hard drives in the array simultaneously. If
a drive fails, the healthy drive continues to work and your data is accessible without interruption.
Once the faulty drive is replaced and the array is rebuilt, the array is restored to its original
condition.
When changing from Independent mode to RAID 1, you have three options:
Keep the data from disk 1 (left drive in chassis)
Keep the data from disk 2 (right drive in chassis)
Don’t keep any data
When changing from RAID 1 to Independent Mode, all data is lost.
