rebuild process. 

Umber 

Slow blink

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.
