SmartStor Responds to a Critical RAID Volume

How the SmartStor responds to a Critical RAID Volume depends on the RAID level of your Volume and whether you have a spare drive available:

•For a RAID 1 Volume or a three-drive RAID 5 Volume, if a spare drive is available, the RAID Volume begins rebuilding itself automatically.

•For RAID 1, 5, and 10 Volumes, when no spare drive is available, you must replace the failed disk drive. The RAID Volume will begin rebuilding itself when you install the new disk drive. See “Replacing a Failed Disk Drive” on page 113.

•RAID 0 Volumes go offline after a disk drive failure. A RAID 0 Volume cannot be rebuilt. All data on the Volume is lost.

Additional Details about Rebuilds

•The Rebuild takes several minutes, depending on the size of your disk drives.

•During a rebuild, you can access your folders on the SmartStor.

•When you replace the failed disk drive with a new disk drive, the new disk drive becomes a Free Drive.

The SmartStor considers a RAID Volume invalid when the RAID Volume was created by a different SmartStor. However, the RAID Volume itself remains functional and the data on it is safe.

This condition could happen when you:

•Move the disk drives from one SmartStor to a different SmartStor.

•Remove the disk drives in order to send your SmartStor for service.
