Problems with Disk Array Configuration

Check the following if the server configuring a disk array does not operate properly or a utility does
not operate correctly. If a relevant item is found, follow the processing method.
Fail to display the BIOS banner to run the utility:
Is the mother board configured?
→ Change the RAID configuration jumper on the mother board (see Chapter 4).
Fail to install the OS:
Is the disk array controller configured?
→ Provide proper configuration for the disk array controller by using the
SoftwareRAID Setup Utility (see Chapter 4).
Fail to start the OS:
Is the BIOS of the disk array controller changed?
→ Change the RAID configuration jumper on the mother board (see Chapter 4).
Does POST recognize the disk array controller?
→ After making sure that the disk array controller is connected correctly, then power
on the server.
→ The disk array controller on the mother board 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.
