Hydra LAN User Guide
2.1.1 Adding more hard drives
It is not possible to add more hard drives once the RAID array has been created, unless
the RAID system is removed and re-built again, loosing all data in the process.
1. Backup all data stored on the Hydra LAN to your computer or another storage drive.
2. Login via web browser, go to the “RAID Setting” section and press the button “Remove
raid system” to remove the RAID array.
3. Install the additional drive(s).
4. In the “RAID Setting” section, create a new RAID array and format the drives.
5. Move the data from your computer or another storage drive back to the Hydra LAN.
Note: When removing the RAID system, all data will be lost!
2.1.2 Replacing a faulty hard drive
When using RAID1 or RAID5, a faulty hard drive can easily be replaced and the data
restored automatically. This can be done using the web browser or with the hardware
buttons (A, B, C, D).
When using RAID 0 or JBOD, the RAID system has to be removed, the new HDD installed
and then the RAID system has to be rebuilt, so all data will be lost!
1. When one of the drives in a RAID 1 or RAID 5 system is defective, the ERROR LED
will light up red.
2. Remove the front panel and check which of the drives has to be replaced. The
corresponding LED from A-D will blink red to indicate the defective drive. In the “RAID
Setting” section of the web interface, the faulty hard drive will be marked by an
exclamation mark.
Note: Never turn off the power, remove or add a hard drive during the rebuild process!
