Problems with RAID System and RAID Controller

Fail to install the OS:

 Did you create virtual disk?

→ Create virtual disks by using WebBIOS.

Fail to start the OS:

 Are hard disk drives properly installed?

→ Install them properly.

If the same error persists, the hard disk drive or RAID Controller may be faulty.

Contact your service representative.

A hard disk drive fails:

→ Contact your service representative.

Rebuild fails:

 Is the capacity of the hard disk drive to be rebuilt sufficient?

→ The hard disk drive to be rebuilt should have the same capacity of the failed had

disk drive.

 Is RAID0 configured for virtual disk?

→ RAID0 has no data redundancy, therefore, Rebuild is disabled in the RAID0

configuration. Replace the failed hard disk drive, then create the virtual disk again.

Check Consistency fails:

 Is virtual disk "Degraded"?

→ Replace the failed hard disk drive with new one, then perform Rebuild.

 Is RAID0 configured for virtual disk?

→ RAID0 has no data redundancy, therefore, Check Consistency 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 additional battery is faulty or insufficiently

charged, the cache mode is changed to "WThru (Write Through)" even if you

specify "WBack (Write Back)". See Chapter 4 for details.
