CPUs not in Duplex mode:
→ Check if the memory configuration is correct.
→ Check if third-party CPUs or memory (DIMM) are used.
Disks not in Duplex mode:
→ Unless you perform mirroring (including reconfiguration after failed disks are
replaced) in correct order, the mirror may not be (re)configured. Check if the
steps were correct.
RAID configuration is not automatically resynchronized even though the failed hard
disk is replaced:
→
Generally, when you replace a failed hard disk, RAID configuration is
automatically resynchronized.
If RAID configuration is not resynchronized automatically, you can
resynchronize it manually.
(See Chapter 3 "Replacing a hard disk drive" for details.)
Occasionally, the replaced disk may not be recognized.
If this happens, follow the steps below.
1) Remove the disk, wait for approximately 15 seconds and then insert the
disk again.
2)If the disk is not recognized even after the operation above,stop the PCI
module in which the unrecognized disk is installed by using ft server utility,
then restart.
See Chapter 3 "Evaluate Startup and Stop of PCI Modules" for information on
starting/stopping PCI module.
The keyboard or mouse fails to operate:
Is the cable properly connected?
→ Make sure that the cable is connected to the correct connector on the rear of the
server.
Are the keyboard and mouse are compliant with NEC Express5800/ft series?
→ Operation of the server with unauthorized devices is not guaranteed.
Does the server have drivers installed?
→ Refer to the manual that comes with your OS to check that the keyboard and
mouse drivers are installed. (These drivers are installed along with the OS.) Some
OS allow you to change the keyboard and mouse settings. Refer to manual that
comes with your OS to check that the keyboard and mouse settings are correct.
