When Operating a RAID System

[?] Unable to rebuild Hard Disk Drive
 Is the capacity of the Hard Disk Drive to be rebuilt enough?
→ Use a Hard Disk Drive with the same capacity as that of the faulty Hard Disk Drive.
 Is the Logical Drive RAID0?
→ RAID0 cannot be rebuilt because it has no redundancy. Replace the failed Hard Disk Drive, recreate the
configuration information, initialize it, and recover the drive using backup data.
[?] Fails to automatically rebuild the Hard Disk Drive
 Did you secure sufficient time for replacing the Hard Disk Drive (hot swap)?
→ To make auto-rebuild work, secure at least 90 seconds from when a Hard Disk Drive is removed to
when the drive is installed.
[?] The Hard Disk Drive failed
→ Contact the maintenance service company with which you signed up or the dealer where you purchased
the product.
[?] Unable to perform Consistency Check
 Is the Logical Drive Critical or Degraded?
→ Replace the failed Hard Disk Drive with new one, and then perform Rebuild.
 Is the Logical Drive RAID0?
→ RAID0 has no data redundancy, and therefore, Consistency Check is disabled in the RAID0
configuration.
