To troubleshoot abnormal RAID operation of your NAS, follow these steps:
Check whether the RAID rebuilding has failed.
When the RAID rebuilding fails:
• The Status LED of the NAS blinks red.
• In the Disk Management > Volume Management window of the web-based
configuration utility of the NAS, the status of the disk volume configuration is
"In degraded mode."
Determine which hard drives caused the RAID rebuilding failure.
In the web-based configuration utility of your NAS, open the System
Administration > System Logs window and search for error messages similar to
the following sample message:
Error occurred while accessing Drive 2.
Drive 2 has been removed.
This message indicates that the hard drive in slot 2 has failed.
Replace the failed drives with new drives.
After inserting the new hard drives, the RAID rebuilding should start.
If the rebuilding succeeds, the NAS will return to normal operation. Skip the
remaining steps.
If the rebuilding fails again due to a read/write error, continue the troubleshooting.
Determine which hard drives caused the error.
• If the error is caused by one of the new drives, go back to
• If the error is caused by an old drive, go to
If the RAID configuration is RAID 1, do one of the following:
Reinstall and set up the NAS:
a. If you haven't done so already, back up the drive data to another storage
device.
b. Reinstall and set up the NAS.
