With the system powered off, you physically connect a new SCSI disk intro the existing SCSI chain. You boot the system using the boot r command.
In which four locations can you find the new device names for the new SCSI disk? (Choose four)

A.
/devices

B.
/dev/dsk

C.
/dev/rdsk

D.
/kernel/drv

E.
/etc/path_to_inst

F.
/etc/name_to_major

G.
/platform/sun4u/kernel/drv

Explanation:

The /devices , /dev/dsk and /dev/rdsk directories are re-built from the boot r command.
path_to_inst stores the physical device names, there is no major_to_minor.
Incorrect
Answers:
The file /etc/name_to_major is used to map the device driver names to the major number mapping.
The /kernel/drv directory is used for tape devices so would not be affected by a new SCSI disk
