What to do if the NEC Express5800 enclosure contains both SAS and SATA drives?
If your NEC Server enclosure contains both SAS and SATA drives, and the controller doesn't allow mixed drive types, contact your service representative to replace the RAID Controller.
What to do if the battery hardware is missing or malfunctioning on NEC Server?
If your NEC Server indicates that the battery hardware is missing, malfunctioning, unplugged, or fully discharged, check if the battery for the RAID Controller is connected properly. If the problem persists after ensuring the connection, contact your service representative for assistance.
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.
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 a low temperature error was detected in NEC Server Storage and I/O Blade?
Check if the ambient temperature of installation location satisfies the operation guarantee condition. If the same error persists, contact your service representative.
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 to do if entering configuration utility results in drive configuration changes on NEC Express5800?
If entering the configuration utility on your NEC Server may result in drive configuration changes, power off your system. Then check all cable connections to ensure all disks are present. If the problem persists after rebooting, contact your service representative.
What to do if NEC Express5800 Server VDs are missing?
If your NEC Server indicates that certain VDs are missing, power off your system and check the cable connections to ensure all disks are properly connected. If the issue persists, contact your service representative for assistance.
What to do if NEC Express5800 VDs have missing disks?
If your NEC Server displays a message indicating that certain VDs have missing disks, check all cable connections to ensure all disks are properly connected. If the problem continues, it is advisable to contact your service representative.
What to do if all disks from the previous configuration are gone on NEC Express5800?
If you receive a message indicating that all disks from your previous configuration are gone on your NEC Server, power off the system immediately. Check all cable connections to ensure all disks are properly connected. If the message was unexpected and the problem persists, contact your service representative.
