Problems with RAID System and RAID Controller
Check the following if the server configuring a RAID System does not operate properly or a
management utility does not operate correctly. If a relevant item is found, follow the processing
method.
Fail to install the OS:
Is the RAID configured?
→ Provide proper configuration for the RAID controller by using the WebBIOS.
Fail to start OS:
Is the BIOS of the RAID controller changed?
→ Provide proper configuration by using the WebBIOS.
Does POST recognize the RAID controller?
→ After making sure that the RAID controller is connected correctly, then power on
the CPU blade.
→ If it is not recognized though the connection is proper, the RAID controller may be
failed. 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?
→ RAID0 has no data redundancy, therefore, Rebuild is disabled in the RAID0
configuration. Replace the failed hard disk drive, create the configuration data
again and initialize the hard disk drives. Then recover the data by using backup
data.
