Question:
A Hard disk error is shown. What can I do?
Answer:
Hard disk error is shown in one or more of the following situations.
1. The message “disk drive x failed or is unplugged” is shown in the Event Log.
2. The message “disk drive x failed or is unplugged” is shown on the LCD panel.
3. An abnormal disk message is shown in the hard disk configuration under administrator mode, e.g. “no disk”.
Note: Some data may not be recovered due to different types of disk damage and the disk configuration (e.g RAID0 vs RAID5 etc.).
* Some possible solutions.
1. For RAID 1 and RAID 5 configurations: Turn off the system and replace the damaged disk(s).
The Ciphertex NAS will perform disk recovery when the system restarts.
The system can run properly and all data can be used again.
Note: It is recommended to replace the damaged disk with a new one of the same manufacturer/model.
2. For a Single disk volume: Turn off the system and replace the damaged disk after the system restarts.
When the NAS restarts, launch the web browser, e.g. IE 8, and login the system.
Go to Disk Configuration page to configure the new disk volume.
Note: Only the data on the other disks or volumes can be recovered.
3. For JBOD and RAID 0: Turn off the system and replace the damaged disk.
When the NAS restarts, launch the web browser, e.g. IE 8, and login the system.
Go to Disk Configuration page to configure the new disk volume.
Note: The data on the damaged disk cannot be recovered.
* Some Maintenance steps.
1. Unlock the disk tray.
2. Take out the disk tray.
3. Determine if any disk is damaged.
Unplug the possible damaged disk and connect it to a test machine in order to determine if it is working.
4. Replace the damaged disk.
5. Make sure the new disk is of the same manufacturer/model as the other ones.
* Disk checking after maintenance:
1. Turn on the NAS.
2. Make sure there is no disk error message shown on the LCD panel.
3. Login to the system as administrator.
4. Check the disk status in disk volume configuration page.
If the message “Not initialized” is shown, the disk is installed successfully.
5. When the disk volume is configured as RAID-1, RAID10, RAID-5 or RAID-6, the system will rebuild upon successful restart. Make sure the system works properly and no errors are displayed after rebuilding.
