Notice
Check
Without accesses, the green lamp may blink frequently. This does not indicate the occurrence of a failure.
It is caused by routine monitoring accesses by NEC ESMPRO or the disk array controller itself or periodical accesses from OS. In addition, due to the nature of the disk array controller, the blinking period against a single access is rather long. Such accesses may cause frequent blinks to occur.
Some servers cannot be equipped with additional HDD cages or can only be equipped with different types of additional HDD cages. Contact your service representative for details.
The disk lamps are controlled by a driver. The umber lamp goes on in installation of OS or every boot of the server. However, this does not indicate the occurrence of a fault. The umber lamp goes off after OS is started to operate the driver.
Rebooting takes place with the lamp status at rebooting remaining unchanged.
