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 165.
• 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.
