Critical & Offline Disk Arrays
A fault-tolerant disk array—RAID 1, 1E, 5, 10, and 50—goes critical when a disk
drive is removed or fails. A RAID 6 or 60 disk array—goes degraded when a disk
drive is removed or fails and critical when two disk drives are removed of fail.
Due to the fault tolerance of the disk array, the data is still available and online.
However, once the disk array goes critical, the disk array has lost its fault
tolerance, and performance may be adversely affected.
If the fault was caused by a failed drive that was removed, the drive must be
replaced by another drive, either identical or larger, in order for the RAID system
to rebuild and restore optimal configuration.
If your fault-tolerant disk array—RAID 1, 1E, 5, 6, 10, 50, and 60— goes offline,
contact Promise Technical Support. See “Contacting Technical Support” on
page 355.
A non-fault tolerant disk array—RAID 0—goes offline when a disk drive is
removed or fails. Since the disk array is not fault tolerant, the data stored in the
disk array is no longer accessible.
If one disk drive fails, all of the data on the disk array is lost. You must replace the
failed drive. Then, if the disk array had more than one disk drive, delete the disk
array and re-create it. Restore the data from a backup source.
When a Physical Drive Fails
VTrak provides both audible and visual indicators to alert you of a disk drive
failure. The following events occur when a disk drive fails or goes offline:
• The Logical Drive LED changes from green to amber. See page 309.
• The Disk Carrier Status LED changes from green to red. See page 310.
• The audible alarm repeatedly sounds two short beeps. See page 307.
• WebPAM PROe reports the condition. See page 318.
Also see “Physical Drive Problems” on page 340.
With a Hot Spare Drive
When a physical drive in a disk array fails and a spare drive of adequate capacity
is available, the disk array will begin to rebuild automatically using the spare
drive.
Warning
Take no further corrective action until you have consulted with
Promise Technical Support.
