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 Controller configured?
→ Provide proper configuration for the RAID Controller by using the LSI Software RAID Configuration Utility
or WebBIOS.
Fail to start the OS:
 Is the BIOS of the RAID Controller changed?
→ Set the BIOS correctly by using the LSI Software RAID Configuration Utility or WebBIOS.
 Does POST recognize the RAID Controller?
→ After making sure that the RAID Controller is connected correctly, then power on the server.
If the RAID Controller is not recognized correctly despite correct connection, 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 hard 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.
Auto rebuild fails:
 Was a sufficient time taken for hot swap of hard disk drives?
→ To allow the auto rebuild to operate correctly, it should take 90 seconds or longer for the interval between the
removal of the failed hard disk drive and the installation of a new hard disk drive.
 Is configuration correct?
→ Check the setting of auto rebuild by using the LSI Software RAID Configuration Utility. <Menus to check:
Top menu - [Objects] - [Adapter] - [Auto Rebuild]>
* Auto Rebuild cannot be specified in WebBIOS.
