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.
