I want to wipe hard disk which is behind the raid controller. I am able to break the raid. After that, i m getting /dev/sg2 not /dev/sda like.
# lsscsi -g [1:1:0:0] disk Hitachi HDxxxx jp40 --- /dev/sg2 [1:1:1:0] disk SAMSUNG HDxxxx 1AA0 --- /dev/sg3
so i have to write this using /dev/sg2 handle. so what is the way to wipe the disk using /dev/sg2 handle.
