Samir,

YOu will need to have mirror/UX product installed in order for you to mirror the volumes. Mirroring is not done at the disk level but at Logical volume level. TO verify if Mirror/UX is installed do

swlist -l product |grep -i mirror

There are few things you have to do before mirroring the boot disk. Search the forums with the string 'mirror boot disk' and you should be able to find many threads explaining the procedures.
