What to do if cache contains dirty data and VDs are missing on NEC Express5800 Server?
If your NEC Server reports that the cache contains dirty data and some VDs are missing or will go offline, power off your system immediately. Check all cable connections to ensure all disks are present. If the error persists, contact your service representative. Be aware that pressing 'X' will permanently discard the cached data.
What causes failed to acquire the current revision on NEC Express5800?
If you are unable to acquire the current revision on your NEC Server, the network may be busy. Try again. If the error persists, contact your service representative because a failure may have occurred in BMC.
Why are NEC Server VDs configured for write-back running in write-through mode?
If your NEC Server's VDs configured for write-back are temporarily running in write-through mode, it's likely due to the battery charging, being missing, or being faulty. Run WebBIOS or Universal RAID Utility to check if battery for RAID Controller is detected. If the battery is not detected, check the connection and allow it to charge for at least 24 hours. If the battery is detected, halt the system for at least 9 hours to charge the battery. If the problem persists, contact your service representative.
What to do if cache data was lost on NEC Express5800 due to unexpected power-off?
If your NEC Server lost cache data due to an unexpected power-off or reboot during a write operation, check the battery connection for the RAID Controller. If the issue persists, contact your service representative to replace the RAID controller and battery.
What is considered Invalid domain name for NEC Express5800 Server?
You can use only alphanumeric characters, minus sign (–), and underscore (_) for a domain name. A domain name should be up to 128 characters.
What is considered Invalid user name for NEC Express5800?
You can use only alphanumeric characters, minus sign (–), and underscore (_) for a user name. A user name should be 31 characters or less.
Why I fail to access (read or write) to the Flash FDD on NEC Express5800 Server?
To resolve issues with accessing (reading or writing) the Flash FDD on your NEC Server, place the write-protect switch on the Flash FDD to the "Write-enabled" Position. Use a formatted Flash FDD. Ensure that only one Flash FDD is connected to a USB connector of this server.
Why is my NEC Server not found on the network?
To resolve the issue of the NEC Server not being found on the network, ensure the cable is securely connected to the network port on the rear of the server. Verify the BIOS settings using the BIOS setup utility. Also, make sure the transfer speed and duplex mode are the same as those on the connected hub.
What to do if multiple single-bit ECC errors are detected on NEC Express5800 Server?
If your NEC Server detects multiple single-bit ECC errors, contact your service representative to replace the RAID Controller.
What to do if single-bit overflow ECC errors are detected on NEC Express5800?
If your NEC Server detects single-bit overflow ECC errors, contact your service representative to replace the RAID Controller.
