SECURSTOR ASTRA ES 131
Warning
Take no further corrective action until you have consulted with
Technical Support.
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
Astra ES provides both audible and visual indicators to alert you of a disk drive failure. The following will occur
when a disk drive fails or goes offline:
• The Logical Drive LED changes from green to amber.
• The Disk Carrier Status LED changes from green to red.
• The audible alarm repeatedly sounds two short beeps.
• Astra Web GUI reports the condition.
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.
After the disk array rebuilds itself using the spare drive, you must replace the failed drive.
Without a Hot Spare Drive
If there is no hot spare drive of adequate capacity, you must remove the failed drive and install an unconfigured
replacement drive of the same or greater capacity in the same slot as the failed drive. Until you install the
replacement drive, the logical drive will remain Degraded.
• If the Auto Rebuild function is ENABLED, the disk array will begin to rebuild automatically as soon as you
replace the failed drive.
• If the Auto Rebuild function is DISABLED, you must manually rebuild the disk array after you replace the
failed drive.
Important
If your replacement disk drive was formerly part of a different disk
array or logical drive, you must clear the configuration data on the
replacement drive before you use it.
Rebuild Operation
During rebuild:
• The alarm sounds a single short beep, repeated
• No warning icon displays over the Disk Array or Logical Drive in the Tree.
Management View reports the Disk Array’s Operational Status as OK, Rebuilding.
• The drive carrier holding the rebuilding physical drive displays a green Activity (lower) LED while the Status
(upper) LED flashes green once per second.
