What to do if READY LED is on and FAULT LED blinks on NEC Storage M100?
If the READY LED (green) is on, and the FAULT LED (orange) blinks (on for 1 second and off for 1 second) on your NEC Disk array system, the issue might be that subsequent disk enclosures are not turned on. The solution is to turn on the disk enclosures.
Why is the INPUT GOOD LED (green) off on my NEC Storage M100 Disk array system?
If the INPUT GOOD LED (green) is off on your NEC Disk array system, it means AC input is not being supplied. Check whether the power supply cable is correctly connected. If the cable is correctly connected, replace the power supply.
What to do if POWER LED and SERVICE LED blink on NEC Storage M100?
If the POWER LED (green) and SERVICE LED (orange) are blinking at intervals (on for 4 seconds and off for 8 seconds) on your NEC Disk array system, it indicates that the battery backup failed during the last power-off state. This can lead to file corruption, so restore those files using backup files. This may occur because a backup device such as a flash memory was destroyed (replace the controller), battery backup was performed past the battery life span, or the disk array unit was continuously used or has been used at a temperature higher than the predetermined temperature.
Why are READY LED blinking and FAULT LED on NEC Storage M100 Disk array system?
If the READY LED (green) is blinking (on for 1 second and off for 1 second), and the FAULT LED (orange) is on on your NEC Disk array system, it means that subsequent disk enclosures cannot be found, or the disk ports are disconnected. Check whether the cables are correctly connected to the disk ports.
How to fix POWER LED off on NEC Storage M100?
If the POWER LED (green) is off on your NEC Disk array system, it means that starting the disk enclosure has not been completed. Check whether the INPUT GOOD LED of the disk enclosure power supply is on, indicating that the power is supplied to the disk enclosure. Check cable connection status to confirm whether this disk enclosure is normally connected to other disk enclosures or the disk array unit. Check POWER LED of the disk array unit to confirm whether the power of the disk array unit was turned on.
What does it mean if INPUT GOOD LED, FAULT LED, and DC GOOD LED are on NEC Storage M100 Disk array system?
If the INPUT GOOD LED (green), FAULT LED (orange), and DC GOOD LED (green) are on on your NEC Disk array system, it indicates a power fan error or that the temperature within the power supply has reached the warning value. The unit has a dual power supply configuration. Therefore, SERVICE LED turns on when FAULT LEDs of both PS0 and PS1 are on.
What does it mean when POWER LED and SERVICE LED are on NEC Storage M100 Disk array system?
If the POWER LED (green) and SERVICE LED (orange) are on on your NEC Disk array system, confirm that power is being supplied to both PS0 and PS1 in the disk array unit or connected disk enclosure. To ensure that power is being supplied, confirm that POWER LEDs of the disk array unit and disk enclosure are on. When SERVICE LED of the connected disk enclosure is on, refer to the description of 'SERVICE LED is on'. When the last operation is maintenance, processing such as disk recovery may take time. Ask the maintenance personnel for the estimated time of completion. If the disk is not recovered beyond the estimated time, ask the maintenance personnel to investigate.
Why is logical disk in disk array not visible from application server on NEC?
If a logical disk in your NEC Disk array system is not visible from the application server (host), there might be an inconsistency in the 'Data Rate' or 'Server Connection Type' settings. Confirm the Server Connection Type between the application server (host) and the disk array unit, and also confirm the Data Rate between the host port and the disk array unit.
What does it mean if READY LED and FAULT LED are on NEC Storage M100 Disk array system?
If the READY LED (green) and FAULT LED (orange) are on on your NEC Disk array system, it means a failure has been detected in the system. Analyze the error and then remove the cause.
