The device map file /boot/grub/device.map is in this format:

(disk) /dev/device

So, for example, on a system with a floppy and a single SCSI disk, the file would look like this:

(fd0) /dev/fd0
(hd0) /dev/sda

I try to display its content :

cat /boot/grub/device.map 

I get this error: No such file or directory

Is it renamed or it is a new hierarchy of Linux system?

The device map is not installed by default with grub2. You can create a device map by typing the following into your console:

sudo grub-mkdevicemap

This will put device.map into the /boot/grub directory.
