When STOP Error Occurs
[?]
Cannot turn the power OFF at the blue screen (STOP error screen)

the power switch for 4 seconds). If you press the switch briefly instead of holding it, the server will
not power off.

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.
[?]
Cannot set Write-Back for Cache Mode
→
The current cache mode of RAID Controller is displayed on Virtual Disks – Properties –
Policies – Write. If an extra battery is faulty, is not connected, or insufficiently charged, the
Cache Mode is changed to WThru (Write Through) even if you specify WBack (Write Back).
