SOLVING PROBLEMS
When the CPU blade does not operate as expected, see the following troubleshooting information
before assuming a failure.
If the CPU blade still fails to operate after following the troubleshooting information, note any error
messages and contact your service representative.
CPU Blade
The operating system cannot be installed:
 Did you create a virtual disk?
→ Create a virtual disk by using WebBIOS (see Chapter 4).
The operating system cannot be started:
 Is the boot priority correct?
→ Run SETUP and select the Boot menu to check the boot priority.
 Are the hard disk drives securely inserted?
→ Install the hard disk drive properly.
Hard disk drive failed:
→ Contact your service representative.
Rebuilding cannot be performed:
 Is the capacity of the hard disk drive to be rebuilt insufficient?
→ Use a hard disk drive of the same capacity as the faulty one.
 Is the RAID level of virtual disk "RAID0"?
→ RAID0 does not have redundancy, thus rebuilding cannot be performed. Replace
the failed hard disk drive and create a virtual disk again.
Consistency Check cannot be performed:
 Is virtual disk indicated as "Degraded"?
→ Replace the failed hard disk drive and execute the rebuild process.
 Is the RAID level of virtual disk "RAID0"?
→ The Consistency Check does not work on RAID0 because it has no redundancy.
